🧱 refactor: typed CodeEnvRef + kind discriminator + principal-aware sandbox cache (#12960)
* 🧱 refactor: typed CodeEnvRef + kind discriminator + tenant-aware sandbox cache Final cutover for the LibreChat ↔ codeapi sandbox file identity. Replaces the magic string `${session_id}/${file_id}?entity_id=...` with a typed, discriminated `CodeEnvRef`. Pre-release lockstep deploy with codeapi #1455 and agents #148; no legacy aliases retained. ## Final shape ```ts type CodeEnvRef = | { kind: 'skill'; id: string; storage_session_id: string; file_id: string; version: number } | { kind: 'agent'; id: string; storage_session_id: string; file_id: string } | { kind: 'user'; id: string; storage_session_id: string; file_id: string }; ``` `kind` drives codeapi's sessionKey: `<tenant>:<kind>:<id>[✌️<version>]` for shared kinds, `<tenant>:user:<userId>` for user-private (auth context provides `userId`). `version` is statically required for `kind: 'skill'` and forbidden otherwise via discriminated union — constraint holds at compile time on every consumer, not just codeapi's runtime validator. `id` is sessionKey-meaningful for `'skill'` / `'agent'`; informational only for `'user'` (codeapi resolves user identity from auth context). ## What changed - `packages/data-provider/src/codeEnvRef.ts` — discriminated union + `CODE_ENV_KINDS` const-tuple keeps the runtime list and TS union locked together. - Schemas: `metadata.codeEnvRef` and `SkillFile.codeEnvRef` enums tightened to `['skill', 'agent', 'user']`. - `primeSkillFiles` writes `kind: 'skill'`, `id: skill._id`, `version: skill.version`. Cache-hit path reads `codeEnvRef` directly. Bumping `skill.version` on edit naturally invalidates the prior cache entry under the new sessionKey. - `processCodeOutput` writes `kind: 'user'`, `id: req.user.id`. Output bucket is always user-scoped, regardless of which skill the execution invoked. New regression test pins the asymmetry. - `primeFiles` reupload preserves `kind`/`id`/`version?` from the existing ref so a skill-cache-miss reupload doesn't silently demote to user bucket. - `crud.js` upload functions (`uploadCodeEnvFile` / `batchUploadCodeEnvFiles`) thread `kind`/`id`/`version?` to the multipart form (codeapi #1455 option α). Without these on the wire, codeapi falls back to user bucketing and skill-cache invalidation never fires. Client-side validation mirrors codeapi's validator. - `Files/process.js` — chat attachments use `kind: 'user'`; agent setup files use `kind: 'agent'`. - Drops `entity_id` everywhere (struct, schema sub-docs, write paths, upload form fields). Drops `'system'` from the kind enum (no emitter ever existed). ## Test plan - [x] `cd packages/data-provider && npx jest src/codeEnvRef.spec` — 4 / 4 - [x] `cd packages/data-schemas && npx jest` — 1447 / 1447 - [x] `cd packages/api && npx jest src/agents` — 81 / 81 in skillFiles + handlers + resources - [x] `cd api && npx jest server/services/Files server/controllers/agents` — 436 / 436 - [x] `cd api && npx jest server/services/Files/Code` — 98 / 98 (incl. new "outputs are user-scoped regardless of which skill the execution invoked" regression and "reupload forwards kind/id/version from existing ref") - [x] `npx tsc --noEmit -p packages/data-{provider,schemas}/tsconfig.json && npx tsc --noEmit -p packages/api/tsconfig.json` — clean (only pre-existing unrelated dev errors in storage/balance, untouched here) ## Deploy notes - **24h cache-miss burst** on first deploy. Inputs (skill caches re-prime under new sessionKey shape) and outputs (any pre-Phase C skill-output cached files become unreadable). Bounded by codeapi's 24h TTL. - **Lockstep with codeapi #1455 and agents #148.** Either repo can land first since no aliases to drain, but the three deploys must overlap within the same maintenance window. - **`@librechat/agents` bump to `3.1.79-dev.0`** required after agents #148 lands and is published. ## What this enables Auth bridge work (JWT-based tenant/user identity between LC and codeapi) — codeapi now derives sessionKey purely from `req.codeApiAuthContext.{ tenantId, userId}`, so the next chapter is replacing the header-asserted user identity with a verified-claim path. * 🩹 fix: persist execute_code uploads under codeEnvRef metadata key Codex review P1 (chatgpt-codex-connector). `Files/process.js` was storing the upload result under `metadata.fileIdentifier` even though: - `uploadCodeEnvFile` now returns `{ storage_session_id, file_id }`, not the legacy magic string. - The post-cutover schema (`File.metadata.codeEnvRef`) only declares `codeEnvRef` — mongoose strict mode silently strips unknown keys. - All readers (`primeFiles`, `getCodeFilesByIds`, `categorizeFileForToolResources`, controller filtering) check `metadata.codeEnvRef`. Net effect of the bug: chat-attached and agent-setup execute_code files would lose their sandbox reference on save, and primeFiles would skip them on subsequent code-execution turns — the file blob would still be available locally but never re-mounted in the sandbox. Fix: construct the full `CodeEnvRef` (`{ kind, id, storage_session_id, file_id }`) at the write site and persist under `metadata.codeEnvRef`. `BaseClient`'s "is this a code-env file" presence check accepts the new shape alongside the legacy `fileIdentifier` for back-compat with any pre-cutover records still in the database. Mirrors the same change in `processAttachments.spec.ts` (which re-implements the BaseClient logic for testability). New regression tests in `process.spec.js` cover three cases: - chat attachments (`messageAttachment=true`) → `kind: 'user'` - agent setup (`messageAttachment=false`) → `kind: 'agent'` - legacy `fileIdentifier` key is NOT persisted (would be schema-stripped) * 🩹 fix: read storage_session_id on primed file refs (Codex P1) Codex review (chatgpt-codex-connector). After Phase B's per-file `session_id` → `storage_session_id` rename, `primeFiles` emits the new field — but `seedCodeFilesIntoSessions` was still reading `files[0].session_id` for the representative session and `f.session_id` for the dedupe key. In runs with only primed attachments (no skill seed), `representativeSessionId` was `undefined`, the function returned the unchanged map, and `seedCodeFilesIntoSessions` silently dropped the entire batch. The first `execute_code` call then started without `_injected_files` and the agent couldn't see prior-turn artifacts. Fix: - `codeFilesSession.ts`: read `f.storage_session_id` for both the dedupe key and the representative session id. JSDoc updated to match the new field name. - `callbacks.js`: the two output-file persistence paths read `file.session_id` to pass to `processCodeOutput` — switch to `file.storage_session_id`. The original comment explicitly says this should be the STORAGE session, which is exactly the field Phase B renamed. - `codeFilesSession.spec.ts`: fixture builder uses `storage_session_id` and `kind: 'user'` to match the post-cutover `CodeEnvFile` shape. Lockstep coordination: this matches the post-bump shape of `@librechat/agents` 3.1.79+. CI tsc errors against the currently-pinned 3.1.78 are expected and resolve when the dep bumps in this PR before merge. * 📦 chore: Bump `@librechat/agents` to version 3.1.80-dev.0 in package-lock and package.json files * 🪪 fix: thread kind/id/version through codeapi /download URLs (Phase C α) Symmetric fix for the upload-side wire change in 537725a. Codeapi's `sessionAuth` middleware now requires `kind`/`id`/`version?` on every download/freshness URL — without them it 400s with "kind must be one of: skill, agent, user" before serving the file. Three sites construct codeapi-side URLs that go through `sessionAuth`: - `processCodeOutput` (`Files/Code/process.js`): `/download/<sess>/<id>` for freshly-generated sandbox outputs. Always `kind: 'user'` + `id: req.user.id` — code-output files are always user-private, regardless of which skill the run invoked. - `getSessionInfo` (`Files/Code/process.js`): `/sessions/<sess>/objects/<id>` for the 23h freshness check. Pulls kind/id/version straight off the `codeEnvRef` already in scope — skill files stay skill-bucketed, user files stay user-bucketed. - `/code/download/:session_id/:fileId` LC route (`routes/files/files.js`): proxies to codeapi for manual downloads. Code-output files only on this route, so `kind: 'user'` + `id: req.user.id`. The `getCodeOutputDownloadStream` helper in `crud.js` now takes an `identity` param, validated by a `buildCodeEnvDownloadQuery` helper that mirrors `appendCodeEnvFileIdentity`'s shape rules: kind required from the closed `{skill, agent, user}` set, version required for 'skill' and forbidden otherwise. Bad callers fail fast on the client instead of round-tripping a 400. Also cleans up two log-noise sources reported alongside the 400: - `logAxiosError` in `packages/api/src/utils/axios.ts` was dumping `error.response.data` raw. With `responseType: 'arraybuffer'` that's a `Buffer` (~4 chars per byte after JSON-serialization); with `responseType: 'stream'` it's a `Readable` whose internal state serializes the entire ring buffer + socket. New `renderResponseData` decodes small buffers as UTF-8 (truncated past 2KB) and stubs streams as `'[stream]'`. Diagnostics stay useful, log lines stop being megabytes. - `/code/download` route's catch was bare `logger.error('...', error)`, bypassing the redactor. Switched to `logAxiosError` so it benefits from the same buffer/stream handling. Tests updated to match the new contract: - crud.spec: `getCodeOutputDownloadStream` fixtures pass `userIdentity`; new cases cover skill identity (with version), bad kind rejection, skill-without-version rejection. - process.spec: `getSessionInfo` test passes a full `codeEnvRef` object. * ♻️ refactor: extract codeEnv identity helpers into packages/api Per the project convention that new backend code lives in TypeScript under `packages/api`, moves `appendCodeEnvFileIdentity` and `buildCodeEnvDownloadQuery` from `api/server/services/Files/Code/crud.js` into a new `packages/api/src/files/code/identity.ts` module. Both helpers are pure validators that mirror codeapi's `parseUploadSessionKeyInput` server-side rules (closed kind set, `version` required for `'skill'` and forbidden otherwise) — they deserve TS support and a dedicated spec rather than living as JSDoc-typed helpers in the legacy `/api` workspace. The new module: - Exports a `CodeEnvIdentity` interface using the `librechat-data-provider` `CodeEnvKind` discriminated union. - Adds 13 unit tests in `identity.spec.ts` covering the validation matrix (skill+version, agent, user, and every rejection path) plus URL encoding for the download query. - Re-exported from `packages/api/src/files/code/index.ts` alongside `classify`, `extract`, and `form`. Consumer updates: - `api/server/services/Files/Code/crud.js`: drops the local helpers and imports them from `@librechat/api`. Net -64 lines. - `api/server/services/Files/Code/process.js`: same. - Test mocks for `@librechat/api` in three spec files now stub the helpers' validation behavior locally rather than pulling them through `requireActual` (which would drag in provider-config init-time side effects). The package's `exports` field only surfaces the root barrel, so leaf imports aren't reachable from legacy `/api` test setup. No runtime behavior change. Identity validation rules and emitted form/query shapes are byte-for-byte identical pre/post. * 🪪 fix: emit resource_id alongside id on _injected_files (skill 403 fix) Companion to codeapi #1455 fix and agents 3.1.80-dev.1 — the wire shape for shared-kind files now requires `resource_id` distinct from the storage `id`. Without this LC change, codeapi's sessionKey re-derivation on every shared-kind /exec rejects with 403 session_key_mismatch: cached: legacy:skill:69dcf561...✌️59 (signed at upload, skill _id) derived: legacy:skill:ysPwEURuPk-...✌️59 (storage nanoid) Emit sites updated: - `primeInvokedSkills` cache-hit path: `resource_id: ref.id` (the persisted skill `_id` from `codeEnvRef.id`); `id: ref.file_id` unchanged (storage uuid). - `primeInvokedSkills` fresh-upload path: `resource_id: skill._id.toString()` on every primed file (the `allPrimedFiles` builder type now carries the field). - `processCodeOutput`'s `pushFile` (Code/process.js): `resource_id: ref.id` — for `kind: 'user'` this is informational (codeapi derives sessionKey from auth context) but emitted for shape uniformity with shared kinds. Bumps `@librechat/agents` to `^3.1.80-dev.1` (the version that ships the matching `CodeEnvFile.resource_id` field). ## Test plan - [x] `cd packages/api && npx jest src/agents` — 67 / 67 pass (skillFiles fixtures updated to assert `resource_id` on the emitted CodeSessionContext.files). - [x] `cd api && npx jest server/services/Files server/controllers/agents` — 445 / 445 pass (process.spec fixtures updated for the reupload + cache-hit emission). - [x] `npx tsc --noEmit -p packages/api/tsconfig.json` — clean. * fix(skill-tool-call): carry resource_id through primeSkillFiles → artifact Codeapi was 400ing every /exec following a `handle_skill` tool call with `resource_id is invalid` (`type: 'undefined'`). Both code paths in `primeSkillFiles` (cache-hit + fresh-upload) returned files without `resource_id`/`kind`/`version`, and the artifact in `handlers.ts` forwarded the stripped shape into `tc.codeSessionContext.files` → `_injected_files`. `primeInvokedSkills` (the NL-detected loader) had already been fixed end-to-end; this commit aligns the tool-invoked path with the same contract: `resource_id` = `skill._id.toString()`, `kind: 'skill'`, `version` = the skill's monotonic counter. Tests added to `skillFiles.spec.ts` lock the contract on `primeSkillFiles` directly so future refactors can't silently drop the resource identity again. * fix(handlers.spec): align session_id → storage_session_id rename + kind discriminator Pre-existing TS errors against the post-rename `CodeEnvFile` shape: the test file still used `session_id` on per-file objects (renamed to `storage_session_id` in agents Phase B/C) and was missing the `kind` discriminator the discriminated union requires. Both inputs and the matching `expect.toEqual(...)` mirrors updated together so the runtime equality check still holds. Lines 723-732 stay as-is — they sit behind `as unknown as ToolCallRequest` and TS already skipped them. * chore: fix `@librechat/agents`, correct version to 3.1.80-dev.0 in package.json files * chore: bump `@librechat/agents` to version 3.1.80-dev.1 in package.json and package-lock.json * chore: bump `@librechat/agents` to version 3.1.80-dev.2 * feat(observability): trace file priming chain from primeCodeFiles to _injected_files Diagnosing the user-upload "files=[] on first /exec" bug requires seeing where in the LC chain a file ref disappears. Prior to this patch the chain (primeCodeFiles → primedCodeFiles → initialSessions → CodeSessionContext → _injected_files) was opaque end-to-end: - primeCodeFiles silently dropped files without `metadata.codeEnvRef` - reuploadFile catches all errors and continues with no signal - the handlers.ts handoff to codeapi never logged what it was sending After this patch, a single grep on `[primeCodeFiles]` plus `[code-env:inject]` shows the full per-file path: [primeCodeFiles] in: file_ids=N resourceFiles=M [primeCodeFiles] file=<id> path=skip reason=no-codeenvref filename=... [primeCodeFiles] file=<id> path=cache-hit-by-session storage_session_id=... [primeCodeFiles] file=<id> path=reupload reason=no-uploadtime ... [primeCodeFiles] file=<id> path=reupload reason=stale ... [primeCodeFiles] file=<id> path=reupload-success oldSession=... newSession=... newFileId=... [primeCodeFiles] file=<id> path=reupload-failed session=... [primeCodeFiles] file=<id> path=fresh-active storage_session_id=... [primeCodeFiles] out: returned=N skippedNoRef=M reuploadFailures=K [code-env:inject] tool=<name> files=N missingResourceId=K (debug) [code-env:inject] M/N files missing resource_id ... (warn) [code-env:inject] tool=<name> _injected_files=0 ... (warn) The boundary log warns when LC sends zero injected files on a code-execution tool call — that's the user's actual symptom showing up at the LC side instead of having to correlate against codeapi's `Request received { files: [] }`. Tag chosen as `[code-env:inject]` rather than `[handoff:exec]` to avoid collision with the app-level "handoff" semantic (subagent handoff workflow). Structural cleanup in primeFiles: replaced the `if (ref) { ... }` nesting with an early `if (!ref) continue` so the per-path instrumentation hooks land at top-level scope instead of indented inside a conditional. Behavior unchanged; pushFile / reuploadFile identical. Spec fixtures (handlers.spec.ts, codeFilesSession.spec.ts) updated to include `resource_id` on `CodeEnvFile` literals — required by the post-3.1.80-dev.2 type now installed. ## Test plan - [x] `cd packages/api && npx jest src/agents/handlers.spec.ts src/agents/codeFilesSession.spec.ts src/agents/skillFiles.spec.ts` — 69/69 pass - [x] `cd api && npx jest server/services/Files/Code/process.spec.js` — 84/84 pass - [x] `npx tsc --noEmit -p packages/api` — clean - [x] `npx eslint` on all four touched files — clean * chore: add CONSOLE_JSON_STRING_LENGTH to .env.example for JSON log string length configuration * fix(files): align codeapi upload filename with LC's sanitized DB filename User-attached files for code execution were uploading to codeapi under `file.originalname` (raw upload filename, may contain spaces / special chars) while LC's DB record stored the sanitized form (`sanitizeFilename(file.originalname)`, underscores). Codeapi preserves whatever filename the upload sent, so the sandbox saw `/mnt/data/<originalname>` while LC's `primeFiles` toolContext text + `_injected_files.name` referenced `file.filename` (sanitized). Visible failure: agent gets system prompt saying /mnt/data/librechat_code_api_-_active_customer_-_2025-11-05.xlsx …tries that path, hits `FileNotFoundError`, then notices the sandbox's actual `Available files` line says /mnt/data/librechat code api - active customer - 2025-11-05.xlsx …retries with spaces, succeeds. Wastes a tool call per upload and leaks raw filenames into model context. Fix: sanitize once and use the sanitized form in both the codeapi upload AND the LC DB record. Sandbox path = LC toolContext text = in-memory ref name. No drift. Reupload path (`Code/process.js` line 867 `filename: file.filename`) already uses the sanitized DB name, so it stays consistent with the fresh-upload path after this change. ## Test plan - [x] `cd api && npx jest server/services/Files/process` — 32/32 pass - [x] `npx eslint` on the touched file — clean * chore: bump `@librechat/agents` to version 3.1.80-dev.3 in package.json and package-lock.json |

🧭 feat: Add Message Navigation Strip & Redesign Scroll-to-Bottom (#12657)
* feat(ui): add message navigation strip and redesign scroll-to-bottom button
Add a floating vertical navigation strip on the right edge of the chat
area that lets users jump between messages quickly. Each message gets an
indicator line (wider for assistant, narrower for user) with HoverCard
previews showing truncated message text. IntersectionObserver tracks
which messages are currently visible and highlights their indicators.
Redesign the scroll-to-bottom button: solid backgrounds instead of
semi-transparent, clean enter/exit animations without twist/rotate,
no hover float animation, positioned at the right edge of the chat
form instead of center.
* fix(ui): prevent message nav layout shift on scroll
Use a fixed-height container for each indicator so the nav strip
maintains consistent dimensions when indicators transition between
active and inactive states.
* fix(ui): debounce message nav refresh and persist visibility state
Debounce entry refresh (200ms) to avoid thrashing from rapid DOM
mutations during code block rendering. Persist the visible message
set across IntersectionObserver reconnections to prevent momentary
empty state that disabled navigation buttons.
* fix(ui): prevent nav buttons from disabling during fast scroll
- Fall back to last known active index when IntersectionObserver
reports no visible messages during rapid scrolling
- Lower intersection threshold from 10% to 1% for long messages
- Fix preview text to skip the message header (Prompt N: username)
* fix(ui): scroll to message start when using nav arrow buttons
Arrow buttons now use block: 'start' to always scroll to the top of
the target message. Indicator dots keep block: 'nearest' for minimal
repositioning on direct clicks.
* fix(ui): account for header offset when scrolling to messages
Use manual scrollTo with a 56px offset to prevent the fixed header
from covering the top of the target message when using arrow buttons.
* fix(ui): improve message nav scrolling and visual subtlety
- Up button scrolls to current message top first before jumping to
previous, preventing skipped messages on long content
- Down button consistently scrolls to the start of the next message
- Nav strip is faded (opacity 30%) by default, fully visible on hover
- Background, buttons, and indicators all appear on hover of the
nav area using group hover coordination
* fix(ui): use native scroll-margin-top for reliable message navigation
Replace manual scrollTo calculations with scrollIntoView + CSS
scroll-margin-top on .message-render elements. The browser handles
scroll offset natively, eliminating positioning errors during smooth
scroll animations.
* fix(ui): use firstActiveIndex for both nav directions
Use firstActiveIndex (topmost visible message) for both up and down
navigation. Down now advances one message at a time from what the user
is currently reading instead of jumping past all visible messages.
Remove unused lastActiveIndex.
* fix(ui): address PR review feedback
- Scope getMessageEntries query to scroll container instead of document
- Include preview text in entries equality check to catch content
updates during streaming/edits
- Move scroll button transition to base state so release animates
smoothly instead of snapping back
* fix(ui): make message nav scroll precise and chevrons reliable
- Bump .message-render scroll-margin-top from 1rem to 4rem so messages
land below the 52px absolute gradient header instead of behind it.
- Drive chevron jumps from live scrollTop + offsetTop comparison rather
than the IntersectionObserver-derived firstActiveIndex, which lagged
behind rapid clicks and treated any 1px-visible message as "current".
- Track canGoUp / canGoDown from the same scroll-position comparison so
the disabled state matches what the buttons will actually do.
- Auto-center the indicator column on the visible message range and
smooth-scroll it via rAF so 500+ indicators stay at 60fps.
- Pull entry data from useGetMessagesByConvoId (with a DOM fallback) so
previews are state-backed instead of scraped from rendered markup.
- Memoize MessageIndicator and filter MutationObserver to .message-render
add/remove only.
- Add 5 i18n keys (com_ui_message_nav*) for nav and indicator labels.
* perf(ui): skip off-screen message layout and fix resulting scroll drift
Large conversations used to freeze the main thread during sidebar
toggles because every animated frame had to relayout every message.
With ~3000 message elements on this branch: avg frame 650ms,
max 1701ms (~1.5fps) during the 300ms transition. Adding
`content-visibility: auto` with `contain-intrinsic-size: auto 200px`
on .message-render lets the browser skip layout/paint for messages
outside the viewport, dropping avg frame to 33ms and max to 74ms
(~30fps, feels responsive).
content-visibility comes with a trade-off though: off-screen messages
use the 200px intrinsic-size estimate until they're measured. That
broke indicator-click scrolling on long conversations, landing 1-2
messages off the target because scrollIntoView computed its target
scrollTop once with stale estimates, and intermediate messages
shrunk/grew as they rendered during the smooth scroll.
Replaced scrollIntoView with a manual rAF scroll that re-reads the
target's getBoundingClientRect every frame and eases toward the
*current* target. Verified drift=0 across fake-0, fake-50, fake-250,
fake-450 (messages near the bottom naturally land higher than
scroll-margin when the container is already at max scroll — expected).
Also two small MessageNav.tsx hot-path cleanups:
- Use col.children[i] instead of col.querySelector by data-msg-id for
the indicator-column centering lookup (entries map 1:1 to column
children since HoverCardTrigger asChild forwards to the button).
- Compare visibility set contents before setActiveIds, so an
IntersectionObserver flush with unchanged membership doesn't force
a re-render and 500x memo comparisons.
* revert(ui): drop content-visibility on .message-render
Didn't deliver the expected sidebar-toggle perf win in real-world
usage, and its intrinsic-size estimation introduced the exact kind of
scroll drift we then had to work around. The rAF scroll in MessageNav
is orthogonal to this and stays — it works fine with or without
content-visibility.
* fix(ui): address PR review — a11y, tests, and MessageNav correctness
- ScrollToBottom aria-label now runs through useLocalize instead of being
hardcoded English. Added com_ui_scroll_to_bottom translation key.
- MessageNav nav expands on keyboard focus-within, not just pointer hover.
- Indicator buttons expose aria-current="true" for the active message and
get a visible focus-visible ring. Chevron buttons get the same ring so
keyboard users can see focus.
- Cancel in-flight rAF scrolls when a new navigation starts, so clicking
a second indicator mid-animation doesn't race the first loop on
container.scrollTop.
- Invalidate the cached offsetsTop/offsetsBottom arrays via a
ResizeObserver on the scroll content. Previously heights that changed
after mount (code blocks rendering, images loading) left canGoUp /
canGoDown and the indicator-column centering reading stale positions.
- Observe IntersectionObserver entries incrementally. The observer is
now created once per scroll container and entries add/remove on
change instead of the whole observer being torn down and rebuilt for
every new message.
- memo() the default export so parent re-renders don't cascade through
MessageNav when entries/activeIds haven't changed.
- Add 18-test suite covering rendering threshold, user/assistant
indicator styling, preview sourcing (React Query vs DOM fallback vs
truncation), accessibility (aria-label, aria-current, chevron
disabled state), click-driven rAF scroll + cancellation, and observer
lifecycle (observe on mount, incremental sync, unobserve on removal,
disconnect on unmount).
* fix(ui): catch in-place message id mutations and react to layout shifts
Follow-ups from deep review:
- MutationObserver on .message-render now also watches the id attribute.
During the SSE lifecycle a single DOM node's id cycles through three
values (client UUID -> createdHandler id -> server id, see the comment
in MultiMessage.tsx), which meant the previous childList-only observer
never refreshed entries after a streaming response. Nav clicks on the
most recent message were silently failing because getElementById
returned null for the stale id.
- ResizeObserver now calls scheduleTick() instead of only flipping a
flag. The flag was only consumed inside the scroll handler's tick, so
heights that changed while the user wasn't scrolling (assistant message
streaming in, code blocks highlighting) left offsetsTop/offsetsBottom
stale and canGoUp / canGoDown wrong. Both handlers now route through
scheduleTick so a resize and a scroll share the same rAF slot.
- Unify scroll and resize callbacks on scheduleTick. Removes a duplicate
rAF path and makes the effect cleaner.
- Single-pass build of newIds during incremental IO sync (previously
entries.map().new Set() did two passes for no reason).
- CSSTransition timeouts drop from 550/700 to 300/250 to match the new
scroll-to-bottom animations. Old values left the button in the DOM
for up to 450ms after the exit animation finished.
- ScrollToBottom.tsx imports reordered to longest-first per project
convention.
- style.css: collapse split `border: 1px solid` + `border-color` into
one shorthand; dark variant still overrides border-color cleanly.
- Tests: add SSE-lifecycle test that mutates a .message-render id in
place and asserts the nav now shows an indicator for the new id and
none for the old one. HoverCard mock no longer spreads unknown props
to the DOM div (drops a React warning).
* fix(ui): address deep-review follow-ups on MessageNav
- Move activeScrollToken from module scope to a per-instance useRef
(scrollTokenRef). When LibreChat eventually mounts more than one
MessageNav side-by-side (multi-panel / added-convo view) a click in
one panel will no longer cancel an in-flight smooth scroll in another.
scrollToMessageStart is now an instance useCallback and the button
click path goes through an onSelect prop on MessageIndicator, keeping
the memoized indicator stable.
- messagesById goes through a ref (messagesByIdRef) so refreshEntries is
no longer recreated on every streaming token. Previously messagesById
landed in both the useMemo and the refreshEntries dep array, so each
streaming response rebuilt the MutationObserver effect dozens of times
per second. A separate small effect still calls refreshEntries when
messagesById changes, so previews stay fresh.
- Extract USER_TURN_SELECTOR constant and tighten the text-preview type
narrowing so we no longer need the `as { value?: string }` cast (TS
narrows string | TextData correctly through the `typeof object` +
property access guard).
- Cache the computed scroll margin (4rem = 64px) in scrollMarginRef so
the nav callbacks don't call getComputedStyle on every click.
- Tests: add a two-instance isolation test that verifies scroll tokens
don't cross between mounted MessageNavs. Drop the unused `import React
from 'react'` pattern in favor of local type aliases.
- client/package.json: bump @babel/preset-typescript to ^7.28.5. The old
^7.22.15 constraint was resolving to 7.23.3 via hoisting, which can't
parse modern `import type` syntax on a clean install and was breaking
the test suite.
* fix(ui): address re-review — clean lockfile + ScrollToBottom ref target
- package-lock.json: the preset-typescript bump last commit pulled in
transitive Babel packages resolved through a local internal registry
(npm.internal.berry13.com). Rewrote those 31 entries back to the
public npmjs.org registry so CI and contributors can install cleanly.
Integrity hashes unchanged — content-addressed.
- ScrollToBottom now forwards its ref to the wrapping <div> instead of
the inner <button>. CSSTransition's nodeRef + unmountOnExit can now
add transition classes to the actual root element, so the layout
wrapper is what mounts/unmounts, not just the button. Updated
scrollToBottomRef type in MessagesView to HTMLDivElement.
- jumpToPrevious / jumpToNext skip the document.getElementById fallback
lookup when scrollMarginRef is already populated, which is the normal
case after the first scroll-tick effect run.
* fix(ui): preserve IntersectionObserver across in-place id mutations
The IO sync effect was observing new ids before unobserving old ones.
During the SSE lifecycle of a fresh chat, a single .message-render node
cycles through three ids (client UUID -> handler id -> server id). When
the id mutated on the same element, the effect would call observe(el)
then unobserve(el) on that element in the same pass — leaving it
permanently unobserved. The active-message highlight never updated for
the new id until a hard refresh rebuilt everything from scratch.
Switched to element-identity tracking. Build an element -> newId map
from entries, then for each currently observed [oldId, el]:
- if the element no longer appears in entries, unobserve and drop it
- if the element appears under a new id, migrate observed and
visibleSet keys in place — the IntersectionObserver keeps watching
the same DOM node uninterrupted
Genuinely new elements get observed afterward as before. Rename doesn't
fire an IO callback, so flush activeIds manually when at least one
migration happened. Existing convos already had this working because
their ids never mutate after load — only fresh chats hit the SSE id
cycle, which matches the reproduction.
* fix(ui): keep message nav current and pinned at bottom

🧬 fix: Subagent MCP requestBody Propagation (bump @librechat/agents to 3.1.78 + cleanup) (#12959)
* 📦 chore: bump `@librechat/agents` to v3.1.78 v3.1.78 ships [danny-avila/agents#147](https://github.com/danny-avila/agents/pull/147), which makes `SubagentExecutor` inherit the parent invocation's `configurable` (with `thread_id`/`run_id`/`parent_run_id` scrubbed) into the child workflow. Subagent tool dispatches through the parent's `ON_TOOL_EXECUTE` handler now arrive with parent's `requestBody`, `user`, `userMCPAuthMap`, etc. — so `{{LIBRECHAT_BODY_*}}` placeholder substitution and per-user MCP connection lookup work for subagent tool calls the same way they do for the parent agent. Note: `package-lock.json` will need an `npm install` refresh once v3.1.78 lands on the registry. The user/user_id injection added in PR #12950 stays as defense-in-depth. * 🗑️ refactor: drop redundant user/user_id injection from `loadToolsForExecution` `@librechat/agents@3.1.78` (via danny-avila/agents#147) makes `SubagentExecutor` forward the parent's `configurable` verbatim into the child workflow. Subagent `ON_TOOL_EXECUTE` dispatches now arrive with parent's `user` / `user_id` already in `data.configurable` — making the host-side injection added in #12950 a no-op. Removes: - The conditional `user: createSafeUser(req.user); user_id: req.user.id` block in `loadToolsForExecution` (req.user.id-guarded so the `'api-user'` fallback in Responses/OpenAI controllers is preserved). - The unused `createSafeUser` import. - The 4 unit tests covering the now-deleted behavior. The merge in `handlers.ts` (`{ ...configurable, ...toolConfigurable }`) still produces a `mergedConfigurable` with the right user identity for both parent and subagent paths — the values just come from `configurable` (forwarded by the SDK) rather than `toolConfigurable`. Other fixes from #12950 stay (IUser.id narrowing, the env.ts / google/initialize.ts / remoteAgentAuth.ts TS-warning fixes) — they were independent of the subagent identity propagation issue. * 📦 chore: update `@librechat/agents` to v3.1.78 This update reflects the transition from the development version `3.1.78-dev.0` to the stable release `3.1.78`. The package-lock.json has been refreshed to ensure consistency with the new version, including updated integrity checks and resolved URLs for the package. This change is part of ongoing improvements to enhance the functionality and stability of the agents module. |

🔐 fix: Forward per-file entity_id through code-env priming (#12958)
* 🔐 fix: Forward per-file `entity_id` through code-env priming Skill files and persisted code-env files now carry their `entity_id` on the in-memory file refs that seed `Graph.sessions`. Without this, an execute call that mixes a skill file (uploaded with `entity_id=skillId`) and a user attachment (uploaded with no `entity_id`) collapses onto a single request-level entity at the codeapi authorization step and one side 403s. With per-file `entity_id`, codeapi resolves sessionKey per file and both authorize. - `primeSkillFiles` / `primeInvokedSkills`: thread `entity_id` through fresh-upload, cache-hit, and per-skill-batch paths in `packages/api/src/agents/skillFiles.ts`. - `primeFiles` (Code/process.js): parse `entity_id` from the persisted `codeEnvIdentifier` query string once per iteration; forward through `pushFile`, including the reupload path which re-parses the fresh identifier returned by codeapi. - Tests: extend `skillFiles.spec.ts` with two cases — fresh-upload propagation and cached-hot-path parsing. Companion PRs in flight on `@librechat/agents` (forward `entity_id` through `_injected_files`) and codeapi (per-file authorization). All three are wire-back-compat: an absent `entity_id` falls back to the existing request-level resolution. * 🔧 chore: Update dependencies in package-lock.json and package.json - Bump `@librechat/agents` to version `3.1.78-dev.0` across multiple package files. - Upgrade `@langchain/langgraph-checkpoint` to version `1.0.2` and update its peer dependency for `@langchain/core` to `^1.1.44`. - Update `axios` to version `1.16.0` and `follow-redirects` to version `1.16.0`. - Add `@types/diff` as a new dependency at version `7.0.2` and include `diff` at version `9.0.0` in the `@librechat/agents` module. - Introduce optional peer dependency `@anthropic-ai/sandbox-runtime` for `@librechat/agents` with metadata indicating it is optional. * 🐛 fix: Make skill code-env cache persistence observable Two changes to surface the skill-bundle re-upload issue without behavioral changes to tenant scoping (root cause to be confirmed via the new warn log): 1. `primeSkillFiles` now awaits `updateSkillFileCodeEnvIds` instead of firing-and-forgetting it. The prior shape could race with the next prime (read-before-write) even when the bulkWrite itself succeeds, producing a silent cache miss. Latency cost: ~10–50ms on first prime; in exchange every subsequent prime can rely on the identifier being persisted by the time it reads. 2. `updateSkillFileCodeEnvIds` now returns `{matchedCount, modifiedCount}` from the underlying bulkWrite. `primeSkillFiles` warn-logs when `modifiedCount < updates.length`, making any silent drop visible — whether the cause is tenant filtering, a `relativePath` mismatch, schema-plugin scoping, or something else. Prior shape returned `Promise<void>` so any zero-modification result was invisible. Tests: - `skill.spec.ts`: real-MongoDB happy path (counts match), no-match case (modifiedCount=0), and empty-input contract. - `skillFiles.spec.ts`: deferred-promise harness proving the call site awaits the persist (prime stays pending until the persist resolves) and forwards partial-write counts. Deliberately narrower than the original draft of this commit, which also bypassed `tenantSafeBulkWrite` for the codeEnvIdentifier write on the speculative diagnosis that tenant filtering was the cause. That change was a behavior shift on tenant scoping without confirmation; reverted pending real-world signal from the new warn log. * 🐛 fix: Justify await for skill code-env persistence under concurrency The await on `updateSkillFileCodeEnvIds` isn't a defensive nicety — it's load-bearing for cache effectiveness under concurrent priming. Verified with an out-of-tree harness (`config/test-skill-cache.ts`, not committed) that wires `primeSkillFiles` against a real codeapi stack: - With fire-and-forget (prior shape after this branch's revert): back-to-back primes for the same skill miss the cache. Call N+1 reads SkillFile docs before Call N's write commits, sees no `codeEnvIdentifier`, re-uploads, fires its own forget that Call N+2 also races. Steady-state stays in cache miss for the full burst. - With await: the prime that does the upload commits its persist before resolving, so the next concurrent prime observes the cache pointer instead of racing the read. Latency cost ~10–50ms on the upload prime; subsequent concurrent primes save an entire batch upload. In production with primes seconds apart this race is rare; at scale with many users hitting the same skill in the same second it's the difference between M and N×M uploads. Updates the regression test to assert the await contract (deferred persist promise → prime stays pending until persist resolves). Comment in `skillFiles.ts` rewritten to document the concurrency rationale rather than the weaker "race-with-next-prime" framing the prior commit used. |

🌩️ feat: CloudFront CDN File Strategy (#12193)
* 🌩️ feat: CloudFront CDN File Strategy + signed cookies Squashed from PR #12193: - feat(storage): add CloudFront CDN file strategy - feat(auth): add CloudFront signed cookie support Note: package.json/package-lock.json dependency additions are intentionally omitted from this commit and will be re-added via `npm install` after rebase to avoid lock-file merge conflicts. The two new peer deps that need to be re-installed are: - @aws-sdk/client-cloudfront@^3.1032.0 - @aws-sdk/cloudfront-signer@^3.1012.0 Also fixes 4 missing destructured names in AuthService.spec.js (getUserById, generateToken, generateRefreshToken, createSession) that were referenced in tests but not imported from the mocked '~/models'. * 📦 chore: install CloudFront SDK deps for PR #12193 Adds the two AWS CloudFront packages required by the rebased CloudFront CDN strategy: - @aws-sdk/client-cloudfront - @aws-sdk/cloudfront-signer Following the @aws-sdk/client-s3 pattern: - api/package.json: regular dependency (runtime resolution) - packages/api/package.json: peerDependency Generated by `npm install` against the freshly rebased lock file to avoid the merge conflicts that came from the original PR's lock-file edits being made against an older base of dev. * 🐛 fix: CI failures + review findings on CloudFront PR #12193 CI fixes - Rename packages/data-provider/src/__tests__/cloudfront-config.test.ts → src/cloudfront-config.spec.ts. Jest's default testMatch picks up __tests__/ directories even inside dist/, so the compiled .d.ts shell was being executed as an empty test suite. Moving to .spec.ts (matching the rest of the package) avoids the dist/ pickup. - Add cookieExpiry: 1800 to CloudFront crud.test makeConfig: the schema applies a default so CloudFrontFullConfig requires it. Review findings addressed - #1 (Codex + comprehensive): Normalize CloudFront domain with /\/+$/ regex (and key with /^\/+/ regex) in buildCloudFrontUrl, matching the cookie code so resource policy and file URLs stay aligned even when the configured domain has multiple trailing slashes. Added tests. - #2: Move DEFAULT_BASE_PATH out of s3Config into shared packages/api/src/storage/constants.ts. ImageService no longer imports S3-specific config. - #3: getCloudFrontConfig() returns Readonly<CloudFrontFullConfig> | null to discourage mutation of the cached signing config. - #4: Add cross-field refinement tests for cloudfrontConfigSchema (invalidateOnDelete-without-distributionId, imageSigning="cookies"-without-cookieDomain). - #6: Revert unrelated MCP comment re-indentation in librechat.example.yaml. - #7: Add azure_blob to the strategy list comment. Skipped - #5 (extractKeyFromS3Url with CloudFront URLs): existing deleteFileFromCloudFront tests already cover the path-equivalence assumption; renaming the helper is real refactor work beyond this PR's scope. - #8, #9 (NIT, low confidence): leaving for author judgement. * 🧹 chore: drop dead DEFAULT_BASE_PATH from s3Config test mock After moving DEFAULT_BASE_PATH to ~/storage/constants, crud.ts no longer reads it from s3Config — so the entry in the s3Config jest mock was misleading dead config. The tests still pass because the unmocked real constants module provides the value. --------- Co-authored-by: Danny Avila <danny@librechat.ai> |

📄 feat: Rich File Artifact Previews for DOCX, CSV, XLSX, PPTX (#12934)
* 📄 feat: Rich File Artifact Previews for DOCX, CSV, XLSX, PPTX Render office files emitted by tools as interactive previews in the artifact panel instead of raw extracted text. The backend produces a sanitized HTML document via mammoth (DOCX), SheetJS (CSV/XLSX/XLS/ODS), or yauzl-based slide extraction (PPTX) and ships it through the existing SSE attachment payload; the client routes it through the Sandpack `static` template's `index.html` slot — no new browser deps, no client-side blob fetch, no React renderer components. * 🔐 fix: Restrict data: URLs to <img> in office HTML sanitizer Codex review on #12934 caught that `data:` lived in the global `allowedSchemes`, which meant a smuggled `<a href="data:text/html, <script>...</script>">` would survive sanitization. The Sandpack iframe sandbox does not gate `target="_blank"` navigations, so a click would open attacker-controlled HTML in a new tab. Scope `data:` to `<img src>` only via `allowedSchemesByTag` (mammoth inlines DOCX images as base64 `data:image/...` URIs — that path still works). Add a regression suite (`sanitizeOfficeHtml security`) with 8 cases covering: <script> stripping, event-handler removal, javascript:/data: rejection on anchors, data:image preservation in <img>, http/https/mailto allowance, target=_blank rel=noopener enforcement, and <iframe> stripping. * 🔧 fix: Route extensionless office files by MIME alone Codex review on #12934 caught that the office-render gate in `extractCodeArtifactText` only fired when the extension was in `OFFICE_HTML_EXTENSIONS` or the category was `document`/`pptx`. A tool emitting `data` with `text/csv` (no extension) classifies as `utf8-text`, so the gate was skipped and raw CSV text shipped to the client — but the client routes by MIME to the SPREADSHEET bucket expecting a full HTML document, so the panel rendered broken text. Extract a shared `officeHtmlBucket(name, mime)` predicate from `html.ts` (returns the bucket name or null). Both `bufferToOfficeHtml` (the dispatcher) and the upstream gate in `extract.ts` now go through this single source of truth, so they can never drift apart again. The predicate already mirrors the dispatcher's extension/MIME logic (extension wins; MIME is the fallback for extensionless inputs). Adds: - 14 cases for the new `officeHtmlBucket` predicate covering the positive paths (each bucket via extension OR MIME) and the negative paths (txt, py, json, jpg, pdf, zip, odt, plain noext). - A direct regression test in `extract.spec.ts` for the Codex catch: `data` with `text/csv` + utf8-text category routes through the office HTML producer. - Parameterized cases for extensionless DOCX/XLSX/XLS/ODS/PPTX files identified by MIME alone. * 🛡️ fix: Enforce extension-wins precedence in officeHtmlBucket Codex review on #12934 caught that the predicate's if-chain interleaved extension and MIME checks for each bucket — e.g. CSV's branch was `ext === 'csv' || CSV_MIME_PATTERN.test(mimeType)`. A `deck.pptx` shipped with `text/csv` (sandboxed tools sometimes ship generic MIMEs) matched the CSV branch BEFORE the PPTX extension branch was reached, so a binary PPTX would have been handed to `csvToHtml` to parse as text — yielding garbage or a parse exception. Restructure to a strict two-pass dispatch: an exhaustive extension table first (one lookup, all known extensions), then MIME-only fallback for extensionless / unknown-ext inputs. The doc comment's "extension wins" claim is now actually enforced by the implementation. Add 7 regression cases covering the conflicting-MIME footgun for each bucket: deck.pptx + text/csv → pptx; workbook.xlsx + text/csv → spreadsheet; legacy.xls + pptx-MIME → spreadsheet; report.docx + text/csv → docx; data.csv + docx-MIME → csv; etc. * 🛡️ fix: Reject zip-bomb office files before in-process parsing (SEC) Addresses pre-existing availability vulnerability validated by SEC review (Codex finding 275344c5...) and made worse by this PR's HTML rendering path. A sub-1MiB compressed XLSX/DOCX/PPTX (highly compressed run-of-zeros) inflates to 200+ MiB of XML when handed to mammoth/xlsx — blocking the Node event loop for 10+ seconds and spiking RSS to ~1 GiB. The existing 8s `withTimeout` wrapper uses `Promise.race`, which can only return early; it cannot interrupt synchronous parser CPU/RAM consumption. PoC ran an authenticated execute_code call to OOM the API process. Add `assertSafeZipSize(buffer)` — a yauzl-based pre-flight that streams every entry with mid-inflate byte counting and bails on either a per-entry or total decompressed-size cap. Mid-inflate counting cannot be bypassed by falsifying the central directory's `uncompressedSize` field (the technique the PoC used). Defaults: 25 MiB per entry, 100 MiB total — generous headroom for legitimate image-heavy office files, well below the attack profile. Hook the check into every path that hands a buffer to mammoth/xlsx /yauzl: - New HTML producers (`wordDocToHtml`, `excelSheetToHtml`, `pptxToSlideListHtml`) — added by this PR - Legacy RAG text extractors (`wordDocToText`, `excelSheetToText` in `crud.ts`) — pre-existing path, also vulnerable Errors propagate as a tag-distinct `ZipBombError` so callers can distinguish a refused bomb from generic parse failures. The outer `extractCodeArtifactText` swallows the error and returns null, falling back to the regular download UI. `.xls` (BIFF/CFB binary, not ZIP) is detected by magic bytes and skipped — yauzl would reject it as malformed anyway. Adds 15 tests: - `zipSafety.spec.ts` (9): benign passes, per-entry cap, total cap, ZipBombError type-tagging, malformed-zip distinction, directory- entry handling, named-error surfacing, and the SEC-PoC pattern (sub-1 MiB compressed → 50 MiB inflated rejected on default caps). - `html.spec.ts` zip-bomb suite (5): each producer rejects a bomb; dispatcher propagates correctly; legitimate fixtures still render. - `extract.spec.ts` (1): outer extractor swallows ZipBombError and returns null so the download UI fallback fires. * 🧹 fix: Normalize MIME parameters; add legacy CSV MIME variant Two related Codex catches on PR #12934 — both about MIME-routing inconsistencies between backend and client that would cause extensionless CSV files to render as broken (raw text under an HTML slot) or skip the artifact panel entirely. P2 — backend MIME normalization: `officeHtmlBucket` matched MIME strings exactly, so a real-world `text/csv; charset=utf-8` Content-Type slipped through and the backend returned raw CSV text. The client's `baseMime` helper strips parameters before its own MIME lookup, so it routed the same file to the SPREADSHEET bucket expecting an HTML body that never arrived. Mirror the client's normalization on the backend (strip everything from `;` onward, lowercase) before bucket matching. P3 — client legacy CSV MIME: Backend's `CSV_MIME_PATTERN` accepts three variants (`text/csv`, `application/csv`, `text/comma-separated-values`); the client's `MIME_TO_TOOL_ARTIFACT_TYPE` only had the first two. An extensionless file with `text/comma-separated-values` would have backend HTML produced but the client would skip the artifact panel entirely. Add the missing variant. Tests: - 9 new parameterized-MIME cases on backend covering charset/ boundary/case variants for every bucket. - 1 new client routing case for `text/comma-separated-values`. * 🩹 fix: Try office HTML before short-circuiting on category=other Codex review on #12934 caught that the early `category === 'other'` return short-circuited before `hasOfficeHtmlPath` was checked. The classifier returns 'other' for inputs the new dispatcher can still route — extensionless `application/csv` (CSV MIMEs aren't in the classifier's text-MIME set and don't start with `text/`), and extensionless office MIMEs with parameters like `application/vnd... spreadsheetml.sheet; charset=binary` (the classifier's `isDocumentMime` exact-matches these MIMEs without parameter normalization). Both would route correctly through `officeHtmlBucket` but never reached it. Move the office-HTML attempt above the 'other' early return, and drop the `|| category === 'document' || category === 'pptx'` shortcut now that `hasOfficeHtmlPath` covers the same surface (with parameter normalization) and a wider one. ODT still routes through `extractDocument` unchanged — `hasOfficeHtmlPath` returns false for it and the `category === 'document'` branch below handles it. Adds 3 regression tests: - extensionless `application/csv` + category='other' → office HTML - extensionless parameterized office MIME + category='other' → office HTML - defense check: actual binary 'other' (image/jpeg) still returns null without invoking the office producer * 🛡️ fix: Office types are HTML-or-null (no text fallback → XSS) Codex P1 review on #12934 caught that when `renderOfficeHtml` failed (timeout, malformed file, zip-bomb rejection) for an office type, the extractor fell through to `extractDocument` and returned plain text. The client routes by extension/MIME to the office preview buckets and feeds `attachment.text` straight into the Sandpack iframe's `index.html`. A spreadsheet cell or document body containing the literal string `<script>alert(1)</script>` would have been injected as executable markup — direct XSS. The contract for office types is now HTML-or-null with no text fallback. Failed render returns null, the client's empty-text gate keeps the artifact off the panel, and the file falls back to the regular download UI (matching what PPTX already did). PDF and ODT still go through `extractDocument` because the client routes them to PLAIN_TEXT (which the markdown viewer escapes) or no artifact at all, so plain text is safe there. Test reshuffle: - `document` describe block now uses ODT/PDF for the legacy parseDocument-path tests (DOCX/XLSX/XLS/ODS bypass that path). - New "does NOT call parseDocument for office HTML types" test locks in the SEC contract for all four office HTML buckets. - "falls back to ..." tests rewritten as "returns null when ..." with explicit `parseDocumentCalls.length === 0` assertions to prove no text leaks back to the client. - New XSS regression test for the XLSX failure path. - Mock parseDocument failure-name match relaxed to `includes()` so ODT-named tests can use the same trigger. * 🧽 chore: Address follow-up review findings on PR #12934 Wraps up the 10-finding follow-up review. Two MAJOR + four MINOR + two NIT addressed; one NIT skipped after verifying it was a misread of the package.json structure. MAJOR - #1: Rewrite `renderOfficeHtml` JSDoc to document the HTML-or-null contract explicitly. The pre-fix doc described a text-fallback path that was the original XSS vector (commit b06f08a). A future maintainer trusting the stale doc could reintroduce the fallback. - #2: Replace byte-truncation of office HTML with a small "preview too large" banner document. Cutting at a UTF-8 boundary lands mid-tag (`<table><tr><td>con\n…[truncated]`) and ships malformed markup to the iframe — unpredictable rendering, occasional broken layouts on DOCX with embedded images / wide spreadsheets. MINOR - #4: Wrap `readSlidesFromZip`'s `zipfile.close()` in try/catch so a close-time exception (mid-flight stream) doesn't replace the original error. Mirrors the defensive pattern in zipSafety.ts. - #5: Refactor PPTX extraction to use `yauzl.fromBuffer` directly, eliminating the temp-file write/unlink the safety pre-flight already proved unnecessary. Removes 4 unused imports (os, path, fs/promises, randomUUID). - #6: Extract `isPreviewOnlyArtifact(type)` to `client/src/utils/ artifacts.ts` so the membership check is unit-testable without mounting the full Artifacts component (Recoil + Sandpack + media query). 15 new test cases covering positive types, negative types, null/undefined, and unknown strings. NIT - #3: Remove dead `stripColorStyles` / `COLOR_PROPERTY_PATTERN` — unused (sanitizer's `allowedStyles` config handles color implicitly). - #7: Remove dead `!_lc_csv_label` worksheet property write. - #9: Remove no-op `exclusiveFilter: () => false` sanitize-html config. - #10: Type-narrow `PREVIEW_ONLY_ARTIFACT_TYPES` to `ReadonlySet<ToolArtifactType>` so the membership table is compile-time checked against the enum. SKIPPED - #8: Reviewer flagged `sanitize-html` as duplicated in devDeps and dependencies. The package has no `dependencies` section — only `devDependencies` and `peerDependencies`. Existing convention (mammoth, xlsx, yauzl, pdfjs-dist) is to appear in BOTH. Removing the devDep entry would break local test runs. Tests: packages/api 4406/4406, client artifacts 128/128. * 🪞 chore: Fix isPreviewOnlyArtifact test description parameter order Follow-up review nit on PR #12934. Jest's `it.each` substitutes `%s` positionally, and the table rows were `[type, expected]` while the description template read `'returns %s for type %s'` — outputting "returns application/vnd.librechat.docx-preview for type true" instead of the intended "type ... returns true". Reorder the template to match the column order. Test runner output now reads naturally: "type application/vnd.librechat.docx-preview returns true". Pure cosmetic — runtime behavior unchanged. * ✨ feat: Improve DOCX rendering and surface filename in panel header Two UX improvements based on hands-on use of the office preview pipeline. DOCX rendering — mammoth strips the navy banners, cell shading, and column layouts that direct-formatted docs apply (python-docx-style output is a common case). The flat `<p><strong>X</strong></p>` and bare `<table><tr><td>` it emits looks washed out next to the source. Three targeted compensations: - Style map promotes `Title`, `Subtitle`, `Heading 1` thru `Heading 6`, and `Quote` paragraphs to their semantic HTML equivalents (mammoth's default only handles Heading 1-6, missing Title/Subtitle/Quote). - Extra CSS scoped to `.lc-docx` gives the first table row sticky- looking header styling regardless of `<thead>` (mammoth never emits `<thead>`), adds zebra striping, and treats the python-docx `<p><strong>X</strong></p>` section-heading idiom as a pseudo-h2 with a thin accent left border so document structure survives the round trip. Headings get a left accent or underline so they read as headings instead of just bold paragraphs. - Sanitizer's `allowedAttributes` opens `class` on the heading and block tags the styleMap and CSS heuristics rely on. `<script>`, event handlers, javascript: URLs, etc. are still stripped — the existing security regression suite catches any drift. Panel header — `Artifacts.tsx` showed a generic "Preview" pill for preview-only artifacts. Single-tab Radio is a no-op; surfacing the document filename there gives the user something useful in the chrome without taking real estate. `displayFilename` handles the sandbox dotfile suffix the upload pipeline applies. Tests: html.spec.ts +1 (new CSS-emission lock), 71/71. Backend files suite 428/428. Client 308/308. * ✨ feat: High-fidelity DOCX preview via docx-preview in iframe Switch the default DOCX render path from server-side mammoth → flat HTML to client-side `docx-preview` loaded inside the Sandpack iframe. Mammoth becomes the fallback for files above the cap. Why --- The Sandpack iframe is a real browser DOM. Server-side rendering ceiling for DOCX→HTML is well below the source's visual fidelity — mammoth strips cell shading, run colors, banners, and column layouts because Word's layout model doesn't fit HTML's flow model. Pushing the render into the iframe lifts that ceiling without paying the server-side cost of jsdom or LibreOffice. What ---- - New `wordDocToHtmlViaCdn(buffer)` builds a self-contained HTML doc that embeds the binary as base64 and lets `docx-preview@0.3.7` render it on load. CSS preserves dark/light mode handoff via `prefers-color-scheme`. Bootstrap script falls back to a "preview unavailable, please download" message if the CDN is unreachable or the parse throws. - `docx-preview` and its `jszip` peer dep are pinned to specific versions on jsdelivr with SRI sha384 integrity hashes and `crossorigin="anonymous"`. Refresh: re-fetch the file, run `openssl dgst -sha384 -binary FILE | openssl base64 -A`. - CSP locked down on the iframe: `default-src 'none'`, scripts only from jsdelivr (no eval), `connect-src 'none'` so a parser bug in docx-preview can't be turned into exfiltration of the embedded document, `base-uri 'none'`, `form-action 'none'`. Defense in depth on top of the Sandpack cross-origin sandbox. - `wordDocToHtml` dispatches by size: ≤ 350 KB binary → CDN path (high fidelity), larger → mammoth fallback (preserves the size cap on `attachment.text`). 350 KB chosen so worst-case base64-inflated output (~478 KB) plus wrapper overhead (~5 KB) fits under MAX_TEXT_CACHE_BYTES (512 KB) with 40 KB headroom. - Internal renderers exported as `_internal` for tests. Public API unchanged — callers still go through `wordDocToHtml`. PPTX intentionally NOT switched ------------------------------- Surveyed the available client-side PPTX libraries: - `pptx-preview@1.0.7` ships an ESM-only main entry plus a 1.36 MB UMD that references `require("stream"/"events"/"buffer"/"util")` — bundled for Node, not browser-clean. Could work but the runtime references to undefined Node globals are a fragility risk worth more validation than this PR can absorb. - `pptxjs` is jQuery-era, requires four separate UMD scripts in a specific order, less actively maintained. - The honest answer for PPTX is the LibreOffice sidecar (DOCX/XLSX/ PPTX → PDF → PDF.js), which is the architecture every major product (Google Drive, Claude.ai, ChatGPT) effectively uses and the only path to ~5/5 fidelity for arbitrary user decks. PPTX stays on the existing slide-list extraction for now. Open a follow-up issue for the LibreOffice/Gotenberg sidecar. Tests ----- - 6 new in CDN-rendered describe block: wrapper structure, base64 round-trip, SRI integrity + crossorigin, CSP locks (connect-src/eval/base-uri/form-action), fallback message wiring, size-threshold lock. - Adjusted 2 existing tests that asserted on mammoth-path artifacts (literal document text in `<article class="lc-docx">`) — those assertions move to the mammoth-fallback test that calls `_internal.wordDocToHtmlViaMammoth` directly. Dispatcher tests now assert CDN-path signatures instead. packages/api files: 434/434 ✅, full unit suite 4473/4473 ✅. * 🧷 fix: Address Codex P1 (MIME aliases) + P2 (CDN dependency) Two follow-up review findings on PR #12934, both real. P1 — Spreadsheet MIME aliases on client ---------------------------------------- Backend's `officeHtmlBucket` uses the broad `excelMimeTypes` regex from `librechat-data-provider` (covers `application/x-ms-excel`, `application/x-msexcel`, `application/msexcel`, `application/x-excel`, `application/x-dos_ms_excel`, `application/xls`, `application/x-xls`, plus the canonical sheet MIMEs). The client's exact-match `MIME_TO_TOOL_ARTIFACT_TYPE` only had three of those, so an extensionless XLS upload with a legacy MIME would have backend HTML produced but the client would fail to route the artifact at all — preview chip never registers. Fix: import the same regex on the client and add it as a fallback in `detectArtifactTypeFromFile` after the exact-match map miss. Stays in lock-step with the backend automatically. 7 new test cases — one per legacy alias. P2 — Hard CDN dependency on jsdelivr ------------------------------------- Air-gapped / corporate-filtered networks where jsdelivr is unreachable would see DOCX previews permanently degrade to "Preview unavailable" because the iframe could never load the renderer scripts. Mammoth was sitting right there on the server but the dispatcher always preferred the CDN path for files under 350 KB. Fix: `OFFICE_PREVIEW_DISABLE_CDN` env var. When truthy (`1`, `true`, `yes`, case-insensitive, whitespace-trimmed), `wordDocToHtml` short-circuits to the mammoth path regardless of file size. Operators on filtered networks set the env var; default behavior is unchanged. Read at function-call time (not module load) so jest can flip it in `beforeEach` without `jest.resetModules()`. The cost is one property access per render. 12 new test cases: env-unset uses CDN (default), all five truthy forms force mammoth, five non-truthy forms (`false`/`0`/`no`/empty/ arbitrary string) leave CDN active. Tests ----- packages/api/src/files: 446/446 ✅ (was 434, +12 from env-var matrix). client artifact suites: 235/235 ✅ (was 228, +7 from MIME aliases). * ✨ feat: High-fidelity PPTX preview via pptx-preview in iframe Mirrors the DOCX CDN architecture for PPTX: small files (≤350 KB binary) embed as base64 and render via `pptx-preview` loaded from jsdelivr inside the Sandpack iframe. Larger files and air-gapped deployments fall back to the existing slide-list extraction. Why --- PPTX is the format where the gap between LibreChat's preview and Claude.ai-style previews was most visible (slide-list of bullet points vs. rendered slide layouts). LibreOffice → PDF → PDF.js is still the eventual gold-standard answer for PPTX fidelity, but client-side rendering inside the Sandpack iframe gets us a meaningful intermediate step (~1.5/5 → ~3.5/5) without a sidecar. What ---- - `pptx-preview@1.0.7` (ISC license, ~1.36 MB UMD bundle that includes its echarts/lodash/uuid/jszip/tslib deps inline). Pinned to a specific version on jsdelivr with SHA-384 SRI and `crossorigin="anonymous"`. - `buildPptxCdnDocument` mirrors the DOCX wrapper: same CSP locks (`default-src 'none'`, `connect-src 'none'`, no eval, no base/form tampering), same `id="lc-doc-data"` base64 slot, same fallback message wiring (`typeof pptxPreview === 'undefined'` → "Preview unavailable"). - New public `pptxToHtml(buffer)` dispatcher; `bufferToOfficeHtml` switches its `'pptx'` case to call it. `pptxToSlideListHtml` stays exported as the slide-list-only path (still hit by tests directly and by the dispatcher fallback). - `OFFICE_PREVIEW_DISABLE_CDN=true` env-var hatch applies to PPTX too — air-gapped operators get the slide-list path. Same env-var read at call time, same matrix of truthy values (`1` / `true` / `yes` / case-insensitive / whitespace-trimmed). - `_internal` re-exports moved to after the PPTX section since the PPTX internals live further down in the file. Adds `pptxToHtmlViaCdn`, `MAX_PPTX_CDN_BINARY_BYTES`, `PPTX_PREVIEW_CDN`. Honest caveats -------------- - The 1.36 MB UMD bundle has `require("stream"/"events"/"buffer"/ "util")` references in its outer wrapper. Those are bundled-dep artifacts (likely from `tslib` / Node-shim transforms) and don't appear to execute on the browser code paths, but I haven't done manual e2e on a wide range of decks. If a class of files turns up that breaks rendering, the iframe-side fallback message catches it and operators have `OFFICE_PREVIEW_DISABLE_CDN=true` as the bail. - First-render CDN fetch is ~1.36 MB (browser-cached after). - PPTX with embedded media easily exceeds the 350 KB binary cap; those files take the slide-list path. Lifting the cap is a follow-up (tied to the broader self-hosting work). Tests ----- 11 new in two new describe blocks: - `pptxToHtml dispatcher`: routing predicate (small → CDN, env-set → slide-list). - `CDN-rendered path`: base64 round-trip, SRI integrity + crossorigin, CSP locks (connect/eval/base/form), fallback message, size-threshold lock at 350 KB. - `OFFICE_PREVIEW_DISABLE_CDN escape hatch`: env-var matrix for truthy values. packages/api/src/files: 457/457 ✅ (was 446, +11). * 🪟 fix: DOCX preview fills the artifact panel width docx-preview defaults to rendering at the document's native page width (8.5in for letter, 21cm for A4). In a wide artifact panel that left whitespace on either side; in a narrow one it forced horizontal scroll. Two changes: - Pass `ignoreWidth: true` to `docx.renderAsync` so the library skips the document's pageSize width and uses its container's width. - Defensive CSS overrides on `.docx-wrapper` and `.docx-wrapper > section.docx` in case a future library version regresses on the option, plus `padding: 0` on the wrapper to drop the page-edge whitespace docx-preview otherwise reserves. `renderHeaders`/`renderFooters`/etc. stay enabled — those still appear in the rendered output, just inside a container that fills the panel instead of a fixed-width "page." Tests unchanged (100/100); manual e2e ahead of merge. * 🩹 fix: PPTX black screen — allow blob: workers + harden bootstrap Manual e2e of the PPTX CDN renderer surfaced a black screen with "Could not establish connection. Receiving end does not exist." unhandled-rejection — characteristic of a Web Worker that couldn't start. Root cause: pptx-preview's bundled echarts dep spins up Web Workers via blob: URLs for chart rendering. Our CSP had `default-src 'none'` and no `worker-src`, so workers fell back to default → blocked. The async failure deep inside echarts didn't surface through the outer `previewer.preview()` promise, so my bootstrap's `.catch` never fired, the loading state was removed, and the iframe sat with the body background showing through (dark navy in dark mode = "black screen"). Three changes: - Add `worker-src blob:` to the PPTX CSP. Allows blob:-only worker creation without permitting arbitrary worker URLs. - Bootstrap: window-level `unhandledrejection` and `error` listeners so rejections from inside bundled-dep async pipelines surface as the user-facing "Preview unavailable" fallback instead of going silent. - Bootstrap: 8-second timeout that checks `container.children.length` — if the renderer hasn't appended anything visible by then, assume silent failure and show the fallback. Also wipe `container.innerHTML` when showing the fallback so a partial render doesn't compete with the message. DOCX wrapper unchanged: docx-preview doesn't use workers, so the worker-src directive doesn't apply, and the existing fallback path already covers its failure modes. Tests ----- - Existing PPTX CSP test now also asserts `worker-src blob:` is present. - Existing fallback-message test extended to cover the new unhandledrejection/error/timeout listeners. packages/api/src/files: 467/467 ✅. * 🔒 fix: gate office HTML routing on backend trust flag (textFormat) Codex P1 review on PR #12934: routing .docx/.csv/.xlsx/.xls/.ods/.pptx into the office preview buckets assumed `attachment.text` was already sanitized full-document HTML, but that guarantee only existed for the new code-output extractor path. Existing stored attachments and other non-code paths can still carry plain extracted text — `useArtifactProps` would then inject that as `index.html` inside the Sandpack iframe. Adds a `textFormat: 'html' | 'text' | null` trust flag persisted on the file record by the code-output extractor, surfaced over the SSE attachment payload and the TFile API type. The client's routing in `detectArtifactTypeFromFile` requires `textFormat === 'html'` before landing on an office HTML bucket; everything else (legacy attachments, RAG-extracted plain text from `parseDocument`, explicitly-marked 'text' entries) falls back to the PLAIN_TEXT bucket where the markdown viewer escapes content rather than executing it. Tests: new `getExtractedTextFormat` helper has 14 cases covering all office paths, legacy XLS MIME aliases, parseDocument fallthroughs, and null-input. Client `artifacts.test.ts` adds three security-gate tests proving downgrade behavior for missing/null/'text' textFormat, plus a `fileToArtifact` test that legacy office attachments without the flag end up in PLAIN_TEXT with their content escaped. * 🌐 fix: air-gapped DOCX preview — embed mammoth fallback in CDN doc Codex P2 review on PR #12934: the CDN-rendered DOCX path always pulled docx-preview + jszip from cdn.jsdelivr.net. Air-gapped or corporate- filtered networks where jsdelivr is blocked would degrade to a static "Preview unavailable" message even though the server already had a local mammoth renderer that could produce readable output. Now the dispatcher renders mammoth first and embeds the sanitized output inside the CDN document as a hidden `#lc-fallback` block. The iframe's existing `typeof docx === 'undefined'` check (which fires when the CDN scripts can't load) un-hides the fallback so the user sees a real preview. CDN-success path is unchanged: high-fidelity docx-preview output owns the viewport, mammoth fallback stays hidden. Two new safeguards in the dispatcher: - Size budget: if base64(binary) + mammoth body + wrapper > 512 KB (the `attachment.text` cache cap), drop to mammoth-only so a giant document still renders. The `OFFICE_HTML_OUTPUT_CAP` constant mirrors `MAX_TEXT_CACHE_BYTES` from extract.ts (separate constant to avoid a circular import; pinned by a unit test). - `lc-render` is hidden when fallback shows so the empty padded slot doesn't sit above the mammoth content. Tests: existing CDN-path tests updated for the new `wordDocToHtmlViaCdn(buffer, mammothBody)` signature; new test for the embedded fallback structure (`#lc-fallback`, mammoth body content, "High-fidelity renderer unavailable" notice, render-slot hide); new constant pin and per-fixture cap-respect assertion. * 🧪 feat: LibreOffice → PDF preview path (POC, opt-in via env) Per the plan-mode discussion: prove out a LibreOffice subprocess pipeline as an alternative to the docx-preview / pptx-preview CDN renderers. LibreOffice handles every office format Microsoft and LibreOffice itself can open (DOCX, PPTX, XLSX, ODT, ODP, ODS, RTF, many more), produces a PDF, and the host browser's built-in PDF viewer renders it inside the Sandpack iframe via a `data:` URI. No client-side JS dependency, no CDN dependency, true high fidelity for any feature LibreOffice supports. Off by default. Operators opt in by setting both: - `OFFICE_PREVIEW_LIBREOFFICE=true` - LibreOffice (`soffice` or `libreoffice`) on the server's `$PATH` When either is missing, the dispatcher falls through to the existing CDN/mammoth/slide-list pipeline so a misconfiguration doesn't break previews. Hardening (`packages/api/src/files/documents/libreoffice.ts`): - Fresh subprocess per call with isolated temp dir, stripped env (PATH/HOME/TMPDIR only), and `-env:UserInstallation` so concurrent conversions can't collide on shared `~/.config/libreoffice` locks - 30-second wall-time cap; SIGKILL on timeout - 50 MB PDF output cap to bound disk pressure - 512 KB output cap on the wrapped HTML so the SSE/cache contract stays intact (base64 inflates ~33%, effective PDF cap ~380 KB) - Macros disabled by default flags (`--norestore --invisible --nodefault --nofirststartwizard --nolockcheck`) - Tag-distinct `LibreOfficeUnavailableError` / `LibreOfficeConversionError` so callers can swallow appropriately Iframe wrapper (`buildPdfEmbedDocument`): - Native browser PDF viewer via `<iframe src="data:application/pdf; base64,...">` — works in Chrome, Edge, Safari, Firefox - CSP locks the iframe to `default-src 'none'; frame-src data:; connect-src 'none'; script-src 'unsafe-inline'` — no outbound network, no eval, no external scripts - `#view=FitH` for first-paint sizing - 4-second heuristic timer that swaps to a "Preview unavailable" fallback when the browser's PDF viewer is disabled (kiosk mode, Brave Shields, etc.) Wired into `wordDocToHtml` and `pptxToHtml` as the first branch — returns null when disabled / unavailable / oversized so the existing pipeline takes over. XLSX intentionally NOT routed through this path: SheetJS's HTML output is already excellent for spreadsheets (sortable, sticky headers) and PDF rendering of sheets is awkward. Tests (`libreoffice.spec.ts`, 30 cases — 25 always run, 5 conditional on the binary): env-gating parser semantics matching `OFFICE_PREVIEW_DISABLE_CDN`, fallthrough contract (never throws, returns null on any failure), CSP lock-down, fallback structure, binary probe caching + missing-binary path, error tagging, and integration tests that engage when `soffice`/`libreoffice` is on PATH (DOCX→PDF, PPTX→PDF, output-cap fallthrough). Integration tests skip cleanly on bare CI. * 🩹 fix: CI — preserve legacy download path for empty-text office attachments Two regressions surfaced after the textFormat security gate landed. 1. **Client** (`LogContent.test.tsx` "falls back to the legacy download branch for an office file with no extracted text"): When the security gate downgraded an office type without `textFormat: 'html'` to PLAIN_TEXT, the lenient empty-text gate on PLAIN_TEXT then accepted a missing `text` field and rendered a half-empty panel card. The historical contract is "office type + no text → legacy download UI"; the downgrade should only fire when there's actual plain text that needs safe-escaping. Fix in `detectArtifactTypeFromFile`: short-circuit to null when the office type lands in the security-gate branch with no text. The PLAIN_TEXT downgrade still fires for legacy attachments that DO carry plain text. 2. **API** (`process.spec.js` + `process-traversal.spec.js`): the `@librechat/api` mocks didn't expose `getExtractedTextFormat`, so `processCodeOutput` called `undefined(...)` → TypeError → tests got undefined results. Added the helper to both mocks with a faithful default (returns 'text' for non-null extractor output, null otherwise). Tests: new regression in `artifacts.test.ts` pinning the empty-text + no-textFormat → null contract for all four office types (.docx/.csv/.xlsx/.pptx), so a future refactor can't silently re-introduce the half-empty card. * 🩹 fix: PPTX slides scale to fit panel width (no horizontal scroll) Manual e2e on PR #12934: pptx-preview rendered slides at their native init dimensions (960×540 default). The artifact panel is much narrower than that, so the iframe got a horizontal scrollbar and only a corner of each slide showed at any time — the user had to drag-scroll across each slide to read it. Fix: keep pptx-preview's init at 960×540 so its internal layout math stays correct, then post-process each rendered slide: - Cache the slide's native width/height on its dataset BEFORE applying any transform (so subsequent re-fits don't measure the already-transformed box). - Wrap the slide in `.lc-slide-wrap` with explicit width/height set inline to the scaled dimensions; the wrap shrinks the layout space the slide occupies. - Apply `transform: scale(panel_width / 960)` to the slide itself with `transform-origin: top left` so the rendered output shrinks from the top-left corner into the wrap. - Cap the scale at 1.0 so small slides don't upscale and get blurry. Streaming + resize: - `MutationObserver` watches the container for slide insertions so streaming renders get scaled on arrival rather than waiting for the entire `previewer.preview` promise to settle. - `ResizeObserver` re-fits all wrapped slides when the iframe resizes (panel drag, window resize). Tests: new "bootstrap wraps + scales each slide" lock in the wrap class, scale computation, observer setup, and native-size caching so a future refactor can't silently re-introduce the overflow. * 🩹 fix: PPTX wrap+scale runs after preview, not during streaming Manual e2e on PR #12934: regenerated PPTX showed "Preview unavailable" in the iframe. Root cause: the MutationObserver I added in the previous commit fired during pptx-preview's render and moved slides out from under the library's references. pptx-preview's async pipeline raised an unhandled rejection, the iframe's window-level listener caught it, and the fallback message replaced the partial render. Fix: drop the MutationObserver. Apply the wrap+scale ONCE in a `finalize` step that runs: - On `previewer.preview().then` (the happy path) - On the 8-second timeout safety net IF the container has children (silent-failure path — pptx-preview emitted slides but never resolved its outer promise) To prevent the user from seeing an unscaled flash while pptx-preview renders into the 960px-wide canvas, the container is set to `visibility: hidden` at init and only revealed inside `finalize` after wrap+scale completes. Resize handling stays via `ResizeObserver` on `document.body`, installed AFTER the wrap pass so it doesn't fire during the wrap itself. Tests: regression assertion now also locks in: - `container.style.visibility = 'hidden' / 'visible'` (the flash- prevention contract) - Absence of MutationObserver (the bug we just removed — must NOT creep back in via a future "let's scale during streaming" idea) * 🩹 fix: PPTX slides fill panel width (drop upscale cap, per-slide scale) Manual e2e on PR #12934: slides rendered correctly but didn't fill the artifact panel — whitespace on either side. Two issues: 1. The scale was capped at `Math.min(1, available / SLIDE_W)`. On panels wider than 960px, the cap clamped the scale to 1.0 and slides rendered at native size with whitespace on the sides instead of stretching. 2. The scale was computed against the constant `SLIDE_W = 960`, but pptx-preview can emit slides whose `offsetWidth` differs from the init param if the source PPTX has a non-16:9 layout. Per-slide division of `available / nativeW` handles that case. Fix: replace `computeScale()` with two helpers — `availableWidth()` returns the panel content-box width and `scaleFor(nativeW)` returns the per-slide scale. No upscale cap. The slide content is rendered by pptx-preview against its 960×540 canvas using vector text / canvas — scaling up to e.g. 1500px doesn't visibly degrade quality. Tests: regression now also asserts: - `availableWidth()` and `scaleFor()` exist by name - The exact scale formula `availableWidth() / (nativeW || SLIDE_W)` - Negative assertion that `Math.min(1, ...)` is NOT present, so a future "let's add an upscale cap" rewrite can't silently re-introduce the whitespace. * 🩹 fix: PPTX preview fills panel height (no white gap below slides) Manual e2e on PR #12934: PPTX preview filled the panel width but left empty space below the last slide. DOCX didn't have this issue because its content (mammoth-rendered HTML) flows naturally and either fits exactly or overflows; PPTX slides are fixed-aspect 16:9 and don't grow with the panel. Two changes: 1. **Body fills the iframe viewport** — `html, body { min-height: 100vh }` plus `body { display: flex; flex-direction: column }` and `#lc-render { flex: 1 0 auto }`. The dark theme bg now fills the iframe even when total slide content is shorter than the panel, so a single-slide deck never reveals a "white below" gap. 2. **Per-slide scale honors viewport height** — `scaleFor(nativeW, nativeH)` now returns `min(width-fit, height-fit)` (largest factor that fits without overflowing either dimension). On a tall artifact panel with a short deck, slides grow up to the full panel height instead of staying at the width-bound size. Existing height-fit was always considered correct conceptually but the previous implementation only used width-fit, leaving half the viewport unused per slide. Tests: regression now also asserts `availableHeight()`, the `Math.min(sw, sh)` formula, and `min-height: 100vh` are in the bootstrap. Negative assertion for the old `Math.min(1, ...)` upscale cap remains. * 🩹 fix: revert body flex on PPTX bootstrap (caused black-screen render) Manual e2e regression on PR #12934: the previous commit added `body { display: flex; flex-direction: column }` plus `#lc-render { flex: 1 0 auto }` to fill the panel height. Side effect: pptx-preview's internal layout assumes block flow on its ancestor elements; making body a flex container caused slides to render as solid-black rectangles (sized correctly, but with no visible content inside). Fix: keep just `html, body { min-height: 100vh }` for the bg-fill effect — that alone gives empty space below short decks the dark theme bg without changing flow. Drop the body-flex and the `#lc-render { flex: 1 0 auto }` directives. The height-aware `scaleFor(nativeW, nativeH)` from the same commit stays — it doesn't interact with pptx-preview's layout, just chooses a per-slide scale. Each slide still grows to fit the viewport contain-style. Negative-assertion added to the regression test: `body { display: flex }` must NOT appear in the bootstrap, so a future "let's flex the body to make height work" rewrite can't silently re-introduce this. (Note: the user also flagged DOCX theming as faint body text; I'm leaving that for now per their note that it may be pre-existing. Not addressed in this commit.) * 🩹 fix: revert PPTX height-fill changes; lock DOCX CDN to light scheme Two fixes for separate manual e2e regressions on PR #12934. **1. PPTX black screen (single slide rendering as solid black).** The previous fix removed `body { display: flex }` thinking that was the sole cause, but the regression persisted.

🌱 fix: Inject Code-Tool Files Into Graph Sessions on First Call (+ read_file Sandbox Fallback) (#12831)
* 🌱 fix: Seed Code Tool Files Into Graph Sessions on First Call
Files attached to an agent's `tool_resources.execute_code` (user uploads
or generated artifacts from a prior turn) were silently dropped on the
first `execute_code` invocation of a turn. The agents-side `ToolNode`
populates `_injected_files` only when its `sessions` map already has an
`EXECUTE_CODE` entry — but that entry is only written by a previous
successful execution, so call #1 had nothing to inject. CodeExecutor
then fell back to a `/files/{session_id}` fetch, but `session_id` was
also empty on call #1, leaving the sandbox without the primed files.
Mirror the existing skill-priming pattern (`primeInvokedSkills` →
`initialSessions`) for code-resource files: eagerly call `primeFiles`
before `createRun` and merge the result into `initialSessions` via a
new `seedCodeFilesIntoSessions` helper. Skill files and code-resource
files now share the same `EXECUTE_CODE` entry; the prior representative
`session_id` is preserved on merge.
* 🔬 chore: Add Diagnostic Logging for Code-Files Seeding
Temporary debug logs to diagnose why first-call file injection is not
firing in real agent runs. Logs `wantsCodeExec`, available tool-resource
keys, primed file count, and the seeded EXECUTE_CODE entry. Will revert
once the failure mode is identified.
* 🪛 refactor: Capture primedCodeFiles per-agent at init, merge across run
Replace the client.js eager `primeFiles` call with a per-agent capture at
initialization time so every agent in a multi-agent run (primary +
handoff + addedConvo) contributes its `tool_resources.execute_code`
files to the shared `Graph.sessions` seed.
- handleTools.js (eager loadTools): the `execute_code` factory closes
over a `primedCodeFiles` slot and surfaces it in the return.
- ToolService.js loadToolDefinitionsWrapper (event-driven): captures
`files` from the existing `primeCodeFiles` call (was dropping them
while only keeping `toolContext`) and surfaces them.
- packages/api initialize.ts: the loadTools callback contract now
includes `primedCodeFiles`, threaded onto `InitializedAgent`.
- client.js: iterate `[primary, ...agentConfigs.values()]` and merge
each agent's `primedCodeFiles` into `initialSessions`. Drop the
primary-only `primeCodeFiles` call and diagnostic logs from the prior
attempt — wrong layer (single-agent), wrong gate (`agent.tools`
contained Tool instances after init, so the `.includes("execute_code")`
string check always failed).
* 🔬 chore: Add per-agent diagnostic logs for code-files seeding
Logs `tool_resources` keys + file counts inside loadToolDefinitionsWrapper
and per-agent `primedCodeFiles` + final initialSessions inside
AgentClient. Will revert once the failure mode is confirmed.
* 🔬 chore: Add file-lookup diagnostics inside initializeAgent
Logs the inputs and intermediate counts of the conversation-file lookup
chain (convo file ids, thread message ids, code-generated and
user-code file counts) so we can pinpoint why `tool_resources.execute_code`
is arriving empty at `loadToolDefinitionsWrapper` despite the agent
having `execute_code` in its tools list.
* 🔬 chore: Probe execute_code files without messageId filter
Adds a relaxed `getFiles({conversationId, context: execute_code})` probe
that runs only when `getCodeGeneratedFiles` returns empty. Lists what's
actually in the DB for this conversation so we can confirm whether the
file is missing entirely or whether the messageId filter is rejecting it.
* 🔬 chore: Fix probe getFiles arg order (sort vs projection)
Probe was passing a projection object as the sort arg, which mongoose
rejected with `Invalid sort value`. Move it to the third arg
(selectFields) so the probe actually runs.
* 🪢 fix: Preserve Original messageId on Code-Output File Update
Each `processCodeOutput` call was overwriting the persisted file's
`messageId` with the *current* run's id. When a turn re-creates an
existing file (filename + conversationId match → `claimCodeFile`
returns the existing record, `isUpdate=true`), the file's link to
the assistant message that originally produced it gets clobbered.
`initializeAgent` later runs `getCodeGeneratedFiles({messageId: $in: <thread>})`
to seed `tool_resources.execute_code` from prior-turn artifacts. With a
stale `messageId` (e.g. from a failed read attempt that re-shelled the
same filename), the file no longer matches the parent-walk thread, so
`tool_resources` arrives empty at agent init, the new
`primedCodeFiles` channel has nothing to seed, and the LLM can't see
its own prior-turn artifacts on the next turn — defeating the
just-added Graph-sessions seeding fix.
Preserve the existing `claimed.messageId` on update; first-creation
behavior is unchanged. The runtime return value still includes the
current run's `messageId` (via `Object.assign(file, { messageId })`)
so the artifact is correctly attributed to the live tool_call.
* 🧹 chore: Remove diagnostic logs from code-files seeding path
Drops the temporary debug logs added to trace the empty-tool_resources
failure mode. Production code paths (loadToolDefinitionsWrapper,
client.js seed loop, initializeAgent file lookup) are left as the
permanent shape: capture primedCodeFiles, merge across agents, seed
initialSessions before run start.
* 🪛 feat: read_file Sandbox Fallback for /mnt/data + Non-Skill Paths
When the model called `read_file` with a code-execution path (e.g.
`/mnt/data/sentinel.txt`), the handler returned a misleading
`Use format: {skillName}/{path}` error. Adds a sandbox-aware fallback:
- Short-circuit `/mnt/data/...` (can never be a skill reference) →
route to a sandbox `cat` via the new host-provided `readSandboxFile`
callback, which POSTs to the codeapi `/exec` endpoint.
- Skip the skill resolver entirely when `accessibleSkillIds` is empty
— the resolved-output of `resolveAgentScopedSkillIds` already
collapses the admin capability + ephemeral badge + persisted
`skills_enabled` chain, so an empty value is the authoritative
"skills aren't in scope for this agent" signal.
- For `{firstSegment}/...` paths, consult the catalog-derived
`activeSkillNames` Set (no DB read) to detect non-skill names and
fall through to the sandbox before the model has to retry with
`bash_tool`.
`activeSkillNames` is captured from `injectSkillCatalog`, threaded onto
`InitializedAgent`, into `agentToolContexts`, then through
`enrichWithSkillConfigurable` into `mergedConfigurable` for the handler.
The host implementation of `readSandboxFile` lives in
`api/server/services/Files/Code/process.js` and shells `cat <path>`
through the seeded sandbox session — `tc.codeSessionContext`
(emitted by ToolNode for `read_file` calls in `@librechat/agents`
v3.1.72+) provides the `session_id` + `_injected_files` so the read
lands in the same sandbox that holds prior-turn artifacts. When the
seeded context isn't available (older agents version, no codeapi
configured), the handler returns a model-visible error pointing at
`bash_tool` instead of silently failing.
Tests: 8 new `handleReadFileCall` cases cover the new short-circuits,
the skills-not-enabled gate, the activeSkillNames lookup, the
sandbox-fallback success path, and the bash_tool retry hint on
fallback failure. Existing `read_file` tests now opt into "skills are
in scope" via a `skillsInScope()` fixture (production wouldn't reach
the skill lookup with empty `accessibleSkillIds`).
* 🔧 chore: Update @librechat/agents dependency to version 3.1.72
Bumps the version of the @librechat/agents package across package-lock.json and relevant package.json files to ensure compatibility with the latest features and fixes.
* 🪛 refactor: Centralize Tool-Session Seed in buildInitialToolSessions Helper
Addresses review feedback on the per-agent merge in client.js:
- **Run-wide semantics, named explicitly.** The merge into a single
`Graph.sessions[EXECUTE_CODE]` was a deliberate match to the
agents-library design (`Graph.sessions` is shared across every
`ToolNode` in the run), but the inline `for (const a of agents)`
loop in `AgentClient.chatCompletion` made it look per-agent. Move
the logic to a TS helper `buildInitialToolSessions` that documents
the run-wide-by-design contract in one place. The CJS controller
now contains a single call site, no business logic.
- **Subagent walk (P2).** The previous loop only iterated
`[primary, ...agentConfigs.values()]`. Pure subagents are pruned
out of `agentConfigs` after init and retained on each parent's
`subagentAgentConfigs`, so their primed code files were silently
dropped from the seed. The helper now walks recursively, with a
visited-Set keyed on object identity that terminates safely on a
malformed agent graph (cycle).
- **`jest.setup.cjs` polyfill for undici `File`.** Reviewer hit
`ReferenceError: File is not defined` running the targeted spec on
WSL — a known Node 18 issue where `globalThis.File` from
`node:buffer` isn't auto-exposed. Polyfill it inside a Jest setup
file so the suite boots regardless of Node patch version.
Helper test coverage (8 new): skill-only / agent-only / both,
recursive subagent walk, cycle-safe walk, primary+subagent
deduplication, undefined/null entries in the agents iterable, and
representative session_id preservation across the merge.
16 tests pass total in `codeFilesSession.spec.ts` (8 prior + 8 new).
No behavior change vs. the previous commit for the existing
primary+agentConfigs case — subagent inclusion is the only new
behavior, and it matches what the existing seeding logic would have
done if subagents had been in `agentConfigs`.
* 🪛 fix: FIFO Walk Order in buildInitialToolSessions (P3 review)
The traversal used `Array.pop()` (LIFO), which visited the LAST
top-level agent first. The docstring says "primary first"; the code
contradicted it. When no skill seed exists the first-visited agent's
first file supplies the representative `session_id` written to
`Graph.sessions[EXECUTE_CODE]` — so a LIFO walk silently flipped which
agent that came from. `ToolNode` ultimately uses per-file `session_id`s
for runtime injection (so behavior was indistinguishable for current
callers), but the discrepancy was a footgun for any future consumer
that read the representative.
Switch to FIFO via `Array.shift()` to match both the docstring and the
existing `loadSubagentsFor` walk pattern in
`Endpoints/agents/initialize.js`. Add a regression test that asserts
the primary's `session_id` is the representative (and that all three
agents' files still contribute, with per-file `session_id`s preserved).
* 🔬 test: Lock In Code-Files Bug Fixes Per Comprehensive Review
Addresses MAJOR + MINOR + NIT findings from the multi-pass review:
**Finding #4 (MINOR) — empty relativePath misses sandbox fallback.**
A model calling `read_file("output/")` where "output" isn't a skill
name dead-ended with `Missing file path after skill name` instead of
being routed to the sandbox like every other malformed-path branch.
Add the same `codeEnvAvailable → handleSandboxFileFallback` pattern,
plus two regression tests.
**Finding #7 (NIT) — duplicate `skillsInScope()` helper.**
Hoist the identical helper out of two nested describe blocks to
module scope. Single source of truth.
**Finding #1 (MAJOR) — `persistedMessageId` had zero test coverage.**
The fix preserves a file's original `messageId` on update so
`getCodeGeneratedFiles` can still match it on subsequent turns. A
regression in the `isUpdate ? (claimed.messageId ?? messageId) : messageId`
ternary would silently re-introduce the original cross-turn priming
bug. Five new tests cover:
- UPDATE preserves `claimed.messageId` in the persisted record
- UPDATE falls back to current run id when `claimed.messageId` is
absent (legacy records predating the field)
- CREATE uses current run id (no claimed record exists)
- The runtime return value uses the LIVE id (artifact attribution)
even when the persisted record kept the original
- The image branch follows the same contract (would silently regress
if the ternary diverged across the two file-build branches)
The tests use a `snapshotCreateFileArgs()` helper because
`processCodeOutput` mutates the file object after `createFile`
returns (`Object.assign(file, { messageId, toolCallId })`) and a
naive `createFile.mock.calls[0][0]` would reflect the post-mutation
state instead of what was actually persisted.
**Finding #2 (MAJOR) — `readSandboxFile` had no direct tests.**
The model-controlled `file_path` flows through a POSIX single-quote
escape into a shell `cat` command, making this a security boundary.
A quoting regression would let a malicious filename break out of the
quoted argument and inject arbitrary shell. 20 new tests across:
- Shell quoting (7): plain filenames, embedded `'`, `$()`, backticks,
newlines, shell metachars, multiple consecutive single-quotes
- Payload shape (6): /exec URL, bash language, conditional
session_id / files inclusion, dedicated keepAlive:false agents
- Response handling (6): `{content}` on success, null on missing
base URL or absent stdout, throws on stderr-only, partial-success
returns stdout, transport errors are logged then rethrown
- Timeout (1): matches processCodeOutput's 15s SLA
Audited findings #5 (acknowledged tech debt — readSandboxFile in JS
workspace), #6 (pre-existing positional-args debt on
enrichWithSkillConfigurable), and #8 (cosmetic JSDoc style) — no
action taken per the reviewer's own assessment.
Audited finding #3 (walk order vs docstring) — already addressed in
commit

🪢 feat: Enable Tool-Output References for Bash Tool (#12830)
* chore: Update `@librechat/agents` to v3.1.71-dev.0 across package-lock and package.json files This commit updates the version of the `@librechat/agents` package from `3.1.70` to `3.1.71-dev.0` in the `package-lock.json` and relevant `package.json` files. Additionally, it marks several dependencies as peer dependencies, ensuring better compatibility and integration across the project. * 🔗 feat: Enable Tool-Output References for bash_tool when codeenv is on Wires `@librechat/agents`' `RunConfig.toolOutputReferences` into `createRun()` and the bash tool's LLM-facing description, gated by the per-agent `effectiveCodeEnvAvailable` flag. The feature auto-activates for any run where the bash tool is actually registered; SDK defaults (~400 KB per output, 5 MB total) match the shell-safe budget. No new env var or yaml capability — piggybacks on the existing `execute_code` gate. - `tools.ts`: replace the module-level `BASH_TOOL_DEF` constant with a per-call `buildBashToolDef` that wraps `buildBashExecutionToolDescription`. Description now includes the `{{tool<idx>turn<turn>}}` reference syntax guide iff the new `enableToolOutputReferences` param is true. - `initialize.ts`: pass `enableToolOutputReferences: effectiveCodeEnvAvailable` into `registerCodeExecutionTools`. - `run.ts`: add `codeEnvAvailable?: boolean` to `RunAgent`, compute the flag from `agents[*].codeEnvAvailable`, and conditionally spread `toolOutputReferences: { enabled: true }` into `Run.create`. * 🧪 test: Cover tool-output references gating end-to-end - `tools.spec.ts`: 3 new cases asserting `bash_tool.description` contains `{{tool<idx>turn<turn>}}` iff `enableToolOutputReferences` is true (and unset → false). - `run-summarization.test.ts`: 4 new cases asserting `Run.create` is invoked with `toolOutputReferences: { enabled: true }` iff at least one `RunAgent.codeEnvAvailable === true`. Covers the present / absent / unset / multi-agent-OR cases. - `initialize.test.ts` + `skills.test.ts`: extend the existing `@librechat/agents` jest mocks with a `buildBashExecutionToolDescription` stub so suites stay green when the on-disk SDK lags the published 3.1.71-dev.0 export. * chore: Update `@librechat/agents` version to `3.1.71-dev.1` in package-lock and package.json files This commit updates the version of the `@librechat/agents` package from `3.1.71-dev.0` to `3.1.71-dev.1` across the relevant package files. This change ensures consistency and incorporates any updates or fixes from the new version. * 🪢 fix: Walk Subagents in toolOutputReferences run-level gate Codex P2 review on PR #12830: the run-level `enableToolOutputReferences` flag only inspected the top-level `agents` array. A parent agent without `execute_code` that spawns a subagent that *does* have it left the SDK's tool-output reference registry inactive for the run, so the subagent's `bash_tool` calls saw `{{tool<idx>turn<turn>}}` placeholders pass through to the shell unsubstituted. Replace `agents.some(a => a.codeEnvAvailable === true)` with a recursive `anyAgentHasCodeEnv` helper that walks `subagentAgentConfigs` transitively. Cycle-safe via a `visited` set, mirroring the existing `buildSubagentConfigs.ancestors` pattern in the same module. The bash tool *description* stays per-agent in `initializeAgent` (only agents with bash actually registered learn the `{{…}}` syntax), so broadening the run-level gate doesn't broaden the model-facing surface — it just lets the SDK's shared registry serve every `ToolNode` the run compiles, which is exactly the contract the SDK already implements. Tests cover three new cases: parent-off / subagent-on, parent-off / child-off / grandchild-on (transitive descent past one level), and a cyclic A↔B tree with neither codeenv-enabled (asserts both termination and absence of `toolOutputReferences`). Existing single-agent and multi-agent tests stay valid since the new helper returns `true` whenever the previous `.some(...)` did. * chore: Update `@librechat/agents` version to `3.1.71` in package-lock and package.json files This commit updates the version of the `@librechat/agents` package from `3.1.71-dev.1` to `3.1.71` across the relevant package files. This change ensures consistency and incorporates any updates or fixes from the stable release. * review: address audit findings on tool-output references PR Two findings from comprehensive PR review on #12830: #1 (MINOR) — `injectSkillCatalog` omitted `enableToolOutputReferences` when calling `registerCodeExecutionTools`, so its resulting `bash_tool` description always lacked the `{{tool<idx>turn<turn>}}` guide. Today this is a no-op because `initializeAgent` registers first and the registry `.has()` check makes the skills-path call a dedupe-only operation. But if call order ever flips (skills-first), the missing flag would silently ship a `bash_tool` without the syntax guide, and the `initializeAgent` pass would itself become the no-op — the feature would silently break with no visible error. Forward `enableToolOutputReferences: codeEnvAvailable === true` so both call sites produce identical tool definitions regardless of firing order. Defense-in-depth, not a current bug. Added a test in `skills.test.ts` that asserts the bash description contains the `{{tool<idx>turn<turn>}}` marker when `codeEnvAvailable` is on, exercising the skills caller end-to-end. #2 (NIT) — `buildBashToolDef` allocated + froze a fresh object on every agent init. Replaced with two module-level frozen singletons (`BASH_TOOL_DEF_WITH_OUTPUT_REFS`, `BASH_TOOL_DEF_WITHOUT_OUTPUT_REFS`) built once at module load via a `createBashToolDef` helper. The factory now picks the right cached reference instead of building. Restores the no-allocation intent of the original `BASH_TOOL_DEF` constant while keeping the per-agent gate behavior. Two new tests in `tools.spec.ts` pin the contract: identical-flag calls return reference-equal `bash_tool` defs across registries; opposite-flag calls return distinct frozen objects with the expected description content. |

🧰 refactor: Unify code-execution tools (#12767)
* 🛠️ feat: Add registerCodeExecutionTools helper Idempotently registers `bash_tool` + `read_file` in the run's tool registry and tool-definition list via a registry `.has()` dedupe. Sets up the single code-execution tool path shared by: - `initializeAgent` (when an agent has `execute_code` in its tools and the capability is enabled for the run) - `injectSkillCatalog` (when skills are active; unconditional read_file, bash_tool follows `codeEnvAvailable`) Both callers reach the helper in the same initialization sequence, so the second call becomes a no-op and exactly one copy of each tool reaches the LLM — no more double registration for agents that combine `execute_code` capability with active skills. Unit-tested on a fresh run, idempotence (second call, overlap with prior tooldefs, partial overlap), and the no-registry variant. * 🔀 refactor: Route injectSkillCatalog bash_tool + read_file through registerCodeExecutionTools The `skill` tool is still registered inline (it's skill-path-specific), but `bash_tool` + `read_file` now flow through the shared idempotent helper so a prior registration from the execute_code path doesn't produce a duplicate copy later in the same run. Behavior preserved: - `read_file` always registers when any active skill is in scope — manually-primed `disable-model-invocation: true` skills still need it to load `references/*` from storage. - `bash_tool` follows `codeEnvAvailable` exactly as before. Adds a test pinning the cross-call dedupe: when `injectSkillCatalog` runs AFTER `registerCodeExecutionTools` has already seeded the registry + tool definitions with bash_tool/read_file, the resulting `toolDefinitions` still contains exactly one copy of each. * 🪄 feat: Expand `execute_code` tool name into bash_tool + read_file at initialize-time When an agent's `tools` include `execute_code` and the `execute_code` capability is enabled for the run, `initializeAgent` now registers `bash_tool` + `read_file` via `registerCodeExecutionTools` before `injectSkillCatalog`. The legacy `execute_code` tool definition is no longer handed to the LLM — `execute_code` remains on the agent document as a capability-trigger marker, but the runtime expands it into the skill-flavored tool pair. Call ordering matters: the `execute_code` registration runs BEFORE `injectSkillCatalog`, so the skill path's own `registerCodeExecutionTools` call inside `injectSkillCatalog` becomes a no-op via the registry's `.has()` check. Exactly one copy of each tool reaches the LLM whether the agent has: - only `execute_code` (legacy path) - only skills - both No data migration needed — `agent.tools: ['execute_code']` stays in the DB unchanged; the expansion is a runtime operation. Three tests cover the matrix: execute_code + capability on → bash_tool + read_file registered; execute_code + capability off → neither registered; no execute_code + capability on → neither registered. * 🗑️ refactor: Drop CodeExecutionToolDefinition from the builtin registry Removes the legacy `execute_code` entry from `agentToolDefinitions` and the corresponding import. With the initialize-time expansion in place, nothing consults `getToolDefinition('execute_code')` for a tool schema any more — the capability gate still filters on the string `execute_code`, but the actual tool definitions the LLM sees come from `registerCodeExecutionTools` (i.e. `bash_tool` + `read_file`). `loadToolDefinitions` in `packages/api/src/tools/definitions.ts` silently drops `execute_code` when it no longer resolves in the registry — that's the expected path and is now covered by an updated test. No caller of `getToolDefinition('execute_code')` expects a non-undefined result after this change. * 🔌 refactor: Read CODE_API_KEY from env for primeCodeFiles + PTC Finishes the Phase 4 server-env-keyed rollout on the two remaining `loadAuthValues({ authFields: [EnvVar.CODE_API_KEY] })` sites in `ToolService.js`: - `primeCodeFiles` (user-attached file priming on execute_code agents) - Programmatic Tool Calling (`createProgrammaticToolCallingTool`) Both now read `process.env[EnvVar.CODE_API_KEY]` directly, matching `bash_tool`'s pattern. The per-user plugin-auth path is no longer consulted for code-env credentials anywhere in the hot path — the agents library owns the actual tool-call execution and also reads the env var internally. Priming still fires for existing user-file workflows so the legacy `toolContextMap[execute_code]` hint ("files available at /mnt/data/...") stays in the prompt; only the key lookup changed. * 🔧 fix: Type the pre-seeded dedupe-test tools as LCTool CI TypeScript type checks caught `{ parameters: {} }` in the new cross-call dedupe test: `LCTool.parameters` is a `JsonSchemaType`, not `{}`. Use `{ type: 'object', properties: {} }` and type the local registry Map through the parameter-derived shape so the pre-seeded values match what `toolRegistry.set` expects. * 🛡️ fix: Run execute_code expansion before GOOGLE_TOOL_CONFLICT gate Codex review caught a latent regression: the original Phase 8 placement ran `registerCodeExecutionTools` after `hasAgentTools` was computed, so an execute-code-only agent on Google/Vertex with provider-specific `options.tools` populated would no longer trip `GOOGLE_TOOL_CONFLICT` — the legacy `CodeExecutionToolDefinition` used to populate `toolDefinitions` before the guard, but after dropping it from the registry, `toolDefinitions` stayed empty until my expansion ran downstream of the guard. Mixed provider + agent tools would silently flow through to the LLM. Fix moves the `execute_code` expansion to BEFORE `hasAgentTools` computation. `bash_tool` + `read_file` now contribute to the check the same way the legacy `execute_code` def did. Covered by a new test that pins the Google+execute_code+provider-tools scenario — the `rejects.toThrow(/google_tool_conflict/)` path would have silently passed on the prior placement. * 🔗 fix: Thread codeEnvAvailable through handoff sub-agents Round-2 codex review caught the other half of the execute_code expansion gap: `discoverConnectedAgents` omitted `codeEnvAvailable` from its forwarded `initializeAgent` params, so handoff sub-agents with `agent.tools: ['execute_code']` lost the `bash_tool` + `read_file` registration (pre-Phase 8 the legacy `CodeExecutionToolDefinition` would have landed in their `toolDefinitions` via the registry). - Add `codeEnvAvailable?` to `DiscoverConnectedAgentsParams` and forward it verbatim on every sub-agent `initializeAgent` call. - Update the three JS call sites that construct the primary's `codeEnvAvailable` (`services/Endpoints/agents/initialize.js`, `controllers/agents/openai.js`, `controllers/agents/responses.js`) to pass the same flag into `discoverConnectedAgents` — one authoritative source per request. - Two regression tests in `discovery.spec.ts` pin the true/false passthrough so a future refactor that drops the param-forwarding surfaces immediately. Left intentionally unchanged: `packages/api/src/agents/openai/service.ts` (public API helper with no in-repo caller). External consumers of `createAgentChatCompletion` who want code execution should pass a `codeEnvAvailable`-aware `initializeAgent` via `deps` — documenting the full public-API surface is out of scope for this Phase 8 PR. * 🔗 fix: Thread codeEnvAvailable through addedConvo + memory-agent paths Round-3 codex review caught the last two production `initializeAgent` callers missing the Phase-8 capability flag: - `api/server/services/Endpoints/agents/addedConvo.js` (multi-convo parallel agent execution). Added `codeEnvAvailable` to `processAddedConvo`'s destructured params and forwarded it into the per-added-agent `initializeAgent` call. Caller in `api/server/services/Endpoints/agents/initialize.js` passes the same `codeEnvAvailable` it computed for the primary. - `api/server/controllers/agents/client.js` (`useMemory` — memory extraction agent). Computes its own `codeEnvAvailable` from `appConfig?.endpoints?.[EModelEndpoint.agents]?.capabilities` and forwards into `initializeAgent`. Memory agents rarely list `execute_code`, but if one does, pre-Phase 8 they got the legacy `execute_code` tool registered unconditionally — the passthrough restores parity. With this, every production caller of `initializeAgent` explicitly resolves the capability: main chat flow (primary + handoff), OpenAI chat completions (primary + handoff), Responses API (primary + handoff), added convo parallel agents, and memory agents. The one remaining caller, `packages/api/src/agents/openai/service.ts::createAgentChatCompletion`, is a public API helper with no in-repo consumer (external callers must pass a capability-aware `initializeAgent` via `deps`). * 🪤 fix: Remove duplicate appConfig declaration causing TDZ ReferenceError The Responses API controller had TWO `const appConfig = req.config;` bindings inside `createResponse`: one at the top of the function (added by the Phase 4 `bash_tool` decouple) and one inside the try block (added by the polish PR #12760). Because `const` is block-scoped with a temporal dead zone, the inner redeclaration put `appConfig` in TDZ for the entire try block, so any earlier reference inside the try — notably `appConfig?.endpoints?.[EModelEndpoint.agents]?.allowedProviders` at line 348 — threw `ReferenceError: Cannot access 'appConfig' before initialization`. The error was silently swallowed by the outer try/catch, leaving `recordCollectedUsage` unreached and the six `responses.unit.spec.js` token-usage tests failing. Removing the inner redeclaration fixes the six failing tests (verified: 11/11 pass locally post-fix, 0 regressions elsewhere). The outer function-scoped binding already provides `appConfig` to every downstream reference. * 🔗 fix: Thread codeEnvAvailable through the OpenAI chat-completion public API Round-4 codex review (legitimate on the type-safety angle, even though the runtime concern was already covered): the `createAgentChatCompletion` helper defines its own narrower `InitializeAgentParams` interface locally, and the type was missing `codeEnvAvailable`. External consumers who supply a capability-aware `deps.initializeAgent` couldn't route `codeEnvAvailable` through without a type-cast workaround. - Widen the local `InitializeAgentParams` interface to include `codeEnvAvailable?: boolean` (matches the real `packages/api/src/agents/initialize.ts` type). - Derive `codeEnvAvailable` inside `createAgentChatCompletion` from `deps.appConfig?.endpoints?.agents?.capabilities` (the same source the in-repo controllers use) and forward to `deps.initializeAgent`. Uses a string literal `'execute_code'` lookup so this file stays free of a `librechat-data-provider` import — keeping the dependency surface of the public helper minimal. With this, external consumers of `createAgentChatCompletion` who pass `appConfig` with the agents capabilities get `bash_tool` + `read_file` registration automatically; consumers who don't pass `appConfig` retain the existing "explicit opt-in" semantics (the flag stays `undefined`, expansion is skipped). * 🧹 chore: Review-driven polish — observability log, JSDoc DRY, test gaps, no-op allocation Addresses the comprehensive review of PR #12767: - **Finding #1** (MINOR, observability): `initializeAgent` now emits a debug log when an agent lists `execute_code` in its tools but the runtime gate is off (`params.codeEnvAvailable` !== true). The event-driven `loadToolDefinitionsWrapper` path doesn't log capability-disabled warnings, so without this the tool silently vanishes from the LLM's definitions with zero trace. Operators debugging "why isn't code interpreter working?" now get a signal at the initialize layer. - **Finding #5** (NIT, allocation): `registerCodeExecutionTools` now returns the input `toolDefinitions` array by reference on the no-op path (both tools already registered by a prior caller in the same run) instead of allocating a fresh spread array every time. The common dual-call scenario — `initializeAgent` then `injectSkillCatalog` — saves one O(n) copy per request. - **Finding #4** (NIT, DRY): Collapsed the duplicated 6-line JSDoc comment in `openai.js`, `responses.js`, and `addedConvo.js` into either a one-line `@see DiscoverConnectedAgentsParams.codeEnvAvailable` pointer (the two JS call sites) or a compact 3-line block referring back to the canonical source (addedConvo's @param). - **Finding #2** (MINOR, test gap): Added `api/server/services/Endpoints/agents/addedConvo.spec.js` with three cases covering `codeEnvAvailable=true`, `codeEnvAvailable=false`, and omitted (undefined) passthrough. A future refactor that drops the param from destructuring now surfaces here instead of silently regressing multi-convo parallel agents with `execute_code`. - **Finding #3** (MINOR, test gap): Added `api/server/controllers/agents/__tests__/client.memory.spec.js` pinning the capability-flag derivation that `AgentClient::useMemory` uses — six cases covering present/absent/null/undefined config shapes plus an enum-literal pin (`'execute_code'` / `'agents'`). Catches enum renames or config-path shifts that would otherwise silently strip `bash_tool` + `read_file` from memory agents. Finding #7 (jest.mock scoping, confidence 40) left as-is: the reviewer's own risk assessment noted `buildToolSet` doesn't touch the mocked exports, and restructuring a file-level `jest.mock` to `jest.doMock` + dynamic `import()` introduces more complexity than the speculative risk justifies. The existing mock is scoped to the test file and contains the same stubs the adjacent `skills.test.ts` already uses. Finding #6 (PR description commit count) addressed out-of-band via PR description update. All existing tests pass, typecheck clean, lint clean across touched files. New tests: 9 cases across 2 new spec files. * 🧽 refactor: Replace hardcoded 'execute_code' string with AgentCapabilities enum in service.ts Follow-up review (conf 55) caught that `openai/service.ts`'s Phase 8 `codeEnvAvailable` derivation used the literal `'execute_code'` while every in-repo controller uses `AgentCapabilities.execute_code` from `librechat-data-provider`. The file deliberately uses local type interfaces to keep the public API helper's type surface small, but that pattern was never a ban on single-value imports from the data provider — `packages/api` already depends on it. Importing the enum value means a future rename of `AgentCapabilities.execute_code` propagates to this file automatically, matching the in-repo controllers' behavior. Other follow-up findings left as-is per the reviewer's own verdict: - #2 (memory spec mirrors the production expression rather than calling `AgentClient::useMemory` directly): reviewer flagged as "not blocking" / "design-philosophy observation." The test file's JSDoc already explicitly documents the tradeoff and pins the enum literals to catch the most likely drift vector. Standing up `AgentClient` + all its mocks for a one-line regression guard is disproportionate. - #3 (`addedConvo.spec.js` mock signature vs. underlying `loadAddedAgent` arity): reviewer's own confidence 25 noted the mock matches the wrapper's actual call pattern in the production file. Not a real gap. - #4 was self-retracted as a false alarm. * 🗑️ refactor: Fully deprecate CODE_API_KEY — remove all LibreChat-side references The code-execution sandbox no longer authenticates via a per-run `CODE_API_KEY` (frontend or backend). Auth moved server-side into the agents library / sandbox service, so LibreChat drops every reference: **Backend plumbing:** - `api/server/services/Files/Code/crud.js`: `getCodeOutputDownloadStream`, `uploadCodeEnvFile`, `batchUploadCodeEnvFiles` no longer accept `apiKey` or send the `X-API-Key` header. - `api/server/services/Files/Code/process.js`: `processCodeOutput`, `getSessionInfo`, `primeFiles` drop the `apiKey` param throughout. - `api/server/services/ToolService.js`: stop reading `process.env[EnvVar.CODE_API_KEY]` for `primeCodeFiles` and PTC; the agents library handles auth internally. Remove the now-dead `loadAuthValues` + `EnvVar` imports. Drop the misleading "LIBRECHAT_CODE_API_KEY" hint from the bash_tool error log. - `api/server/services/Files/process.js`: remove the `loadAuthValues` call around `uploadCodeEnvFile`. - `api/server/routes/files/files.js`: code-env file download no longer fetches a per-user key. - `api/server/controllers/tools.js`: `execute_code` is no longer a tool that needs verifyToolAuth with `[EnvVar.CODE_API_KEY]` — the endpoint always reports system-authenticated so the client skips the key-entry dialog. `processCodeOutput` called without `apiKey`. - `api/server/controllers/agents/callbacks.js`: `processCodeOutput` invoked without the loadAuthValues round trip, for both LegacyHandler and Responses-API handlers. - `api/app/clients/tools/util/handleTools.js`: `createCodeExecutionTool` called with just `user_id` + files. **packages/api:** - `packages/api/src/agents/skillFiles.ts`: `PrimeSkillFilesParams`, `PrimeInvokedSkillsDeps`, `primeSkillFiles`, `primeInvokedSkills` all drop the `apiKey` param; the gate is purely `codeEnvAvailable`. - `packages/api/src/agents/handlers.ts`: `handleSkillToolCall` drops the `process.env[EnvVar.CODE_API_KEY]` read; skill-file priming is now gated solely on `codeEnvAvailable`. `ToolExecuteOptions` signatures drop apiKey from `batchUploadCodeEnvFiles` and `getSessionInfo`. - `packages/api/src/agents/skillConfigurable.ts`: JSDoc no longer references the env var. - `packages/api/src/tools/classification.ts`: PTC creation no longer gated on `loadAuthValues`; `buildToolClassification` drops the `loadAuthValues` dep entirely (no LibreChat-side callers need it for this path anymore). - `packages/api/src/tools/definitions.ts`: `LoadToolDefinitionsDeps` drops the `loadAuthValues` field. **Frontend:** - Delete `client/src/hooks/Plugins/useAuthCodeTool.ts`, `useCodeApiKeyForm.ts`, and `client/src/components/SidePanel/Agents/Code/ApiKeyDialog.tsx` — the install/revoke dialogs for CODE_API_KEY are fully dead. - `BadgeRowContext.tsx`: drop `codeApiKeyForm` from the context type and provider. `codeInterpreter` toggle treated as always authenticated (sandbox auth is server-side). - `ToolsDropdown.tsx`, `ToolDialogs.tsx`, `CodeInterpreter.tsx`, `RunCode.tsx`, `SidePanel/Agents/Code/Action.tsx` +`Form.tsx`: all API-key dialog trigger refs, "Configure code interpreter" gear buttons, and auth-verification plumbing removed. The "Code Interpreter" toggle is now a plain `AgentCapabilities.execute_code` checkbox — no key-entry gate. - `client/src/locales/en/translation.json`: drop the three `com_ui_librechat_code_api*` keys and `com_ui_add_code_interpreter_api_key`. Other locales are externally automated per CLAUDE.md. **Config:** - `.env.example`: remove the `# LIBRECHAT_CODE_API_KEY=your-key` section and its header. **Tests:** - `crud.spec.js`: assertions flipped to pin "no X-API-Key header" and "no apiKey param". - `skillFiles.spec.ts`: removed env-var save/restore; tests now pin that the batch-upload path is gated solely on `codeEnvAvailable` and that no apiKey is threaded through. - `handlers.spec.ts`: same — just the `codeEnvAvailable` gate pins remain. - `classification.spec.ts`: remove the two tests that asserted `loadAuthValues` was (not) called for PTC. - `definitions.spec.ts`: drop every `loadAuthValues: mockLoadAuthValues` entry from the deps shape. - `process.spec.js`: strip the mock of `EnvVar.CODE_API_KEY`. **Comment hygiene:** - `tools.ts`, `initialize.ts`, `registry/definitions.ts`: shortened stale comment references to "legacy `execute_code` tool" without naming the retired env var. Tests verified: 678 packages/api tests pass, 836 backend api tests pass. Typecheck clean, lint clean. Only remaining CODE_API_KEY mentions in the code are two regression-guard assertions: - `crud.spec.js`: pins "no X-API-Key header" stays absent. - `skillConfigurable.spec.ts`: pins `configurable` never grows a `codeApiKey` field. * 🧹 chore: Remove the last two CODE_API_KEY name mentions in LibreChat Follow-up to the prior full deprecation commit: two tests still named the retired identifier in their regression-guard assertions. - `packages/api/src/agents/skillConfigurable.spec.ts`: drop the "does not inject a codeApiKey key" test. The `codeApiKey` field is gone from the production configurable shape, so an absence-assertion naming it re-introduces the retired identifier in code. - `api/server/services/Files/Code/crud.spec.js`: rename the "without an X-API-Key header" case back to "should request stream response from the correct URL" and drop the `expect(headers).not.toHaveProperty('X-API-Key')` assertion. The surrounding request-shape checks (URL, timeout, responseType) still pin the behavior; the explicit header-absence line was named-after the deprecated contract. Result: `grep -rn "CODE_API_KEY\|codeApiKey\|LIBRECHAT_CODE_API_KEY"` against the LibreChat source tree returns zero hits. The only remaining `X-API-Key` strings in this repo are on unrelated OpenAPI Action + MCP server auth configurations, where the string is user-facing config, not a LibreChat-owned identifier. Tests: 677 packages/api pass (2 pre-existing summarization e2e failures unrelated); 126 api-workspace controller/service tests pass. Typecheck and lint clean. * 🎯 fix: Narrow codeEnvAvailable to per-agent (admin cap AND agent.tools) Before this commit, `codeEnvAvailable` was computed in the three JS controllers as the admin-level capability flag only (`enabledCapabilities.has(AgentCapabilities.execute_code)`) and passed through `initializeAgent` → `injectSkillCatalog` / `primeInvokedSkills` / `enrichWithSkillConfigurable` unchanged. A skills-only agent whose `tools` array didn't include `execute_code` still got `bash_tool` registered (via `injectSkillCatalog`) and skill files re-primed to the sandbox on every turn — wrong, because the agent never opted in to code execution. **Fix:** `initializeAgent` now computes the per-agent effective value once as `params.codeEnvAvailable === true && agent.tools.includes(Tools.execute_code)`, reuses the same boolean for: 1. The `execute_code` → `bash_tool + read_file` expansion gate (previously already consulted `agent.tools`; now shares the single `effectiveCodeEnvAvailable` binding). 2. The `injectSkillCatalog` call (previously got the raw admin flag). 3. The returned `InitializedAgent.codeEnvAvailable` field (new, typed as required boolean). **Controllers (initialize.js, openai.js, responses.js):** store `primaryConfig.codeEnvAvailable` in `agentToolContexts.set(primaryId, ...)`, capture `config.codeEnvAvailable` in every handoff `onAgentInitialized` callback, and read it from the per-agent ctx inside the `toolExecuteOptions.loadTools` runtime closure. The hoisted `const codeEnvAvailable = enabledCapabilities.has(...)` locals in the two OpenAI-compat controllers are gone — they were shadowing the narrowed per-agent value. **primeInvokedSkills:** `handlePrimeInvokedSkills` in `services/Endpoints/agents/initialize.js` now uses `primaryConfig.codeEnvAvailable` (per-agent, narrowed) instead of the raw admin flag. A skills-only primary agent won't re-prime historical skill files to the sandbox even when the admin enabled the capability globally. **Efficiency:** one extra `&&` in `initializeAgent`. No runtime hot-path cost — the `includes()` scan on `agent.tools` was already happening for the `execute_code` expansion gate; it's now just bound to a local. Tool execution closures read `ctx.codeEnvAvailable === true` (property access + strict equality, O(1)). **Ephemeral-agent note:** per-agent narrowing is authoritative for both persisted and ephemeral flows. The ephemeral toggle (`ephemeralAgent.execute_code`) is reconciled into `agent.tools` upstream in `packages/api/src/agents/added.ts`, so `agent.tools.includes('execute_code')` is the single source of truth by the time `initializeAgent` runs. **Tests:** two new regression tests pin the narrowing contract: - `initialize.test.ts` — four-quadrant matrix on `InitializedAgent.codeEnvAvailable` (cap on × agent asks, cap on × doesn't ask, cap off × asks, neither). Catches future refactors that drop either half of the AND. - `skills.test.ts` — `injectSkillCatalog` with `codeEnvAvailable: false` against an active skill catalog must NOT register `bash_tool` even though it still registers `read_file` + `skill`. This is the state a skills-only agent gets post-narrowing. All 191 affected packages/api tests pass + 836 backend api tests pass. Typecheck clean, lint clean. * 🧽 refactor: Comprehensive-review polish — hoist tool defs, pin verifyToolAuth contract, doc appConfig Addresses the comprehensive review of Phase 8. Findings mapped: **#1 (MINOR): `verifyToolAuth` unconditional auth for execute_code** - Added doc comment explicitly stating the deployment contract (admin capability → reachable sandbox; no per-check health probe to keep UI-gate queries O(1)). - New `api/server/controllers/__tests__/tools.verifyToolAuth.spec.js` with 4 regression tests pinning the contract: 1. `authenticated: true` + `SYSTEM_DEFINED` for execute_code. 2. 404 for unknown tool IDs. 3. `loadAuthValues` is never consulted (catches a future revert that would resurface the per-user key-entry dialog). 4. Response `message` is never `USER_PROVIDED`. **#2 (MINOR): `openai/service.ts` undocumented `appConfig` dependency** - Expanded the `ChatCompletionDependencies.appConfig` JSDoc to spell out that omitting it silently disables code execution for agents with `execute_code` in their tools. External consumers of `createAgentChatCompletion` now have the contract documented at the type boundary. **#5 (NIT): `registerCodeExecutionTools` re-allocates tool defs** - Hoisted `READ_FILE_DEF` and `BASH_TOOL_DEF` to module-level `Object.freeze`d constants. The shapes derive entirely from static `@librechat/agents` exports, so a single frozen object per tool is safe to share across every agent init. Eliminates the ~4-property allocations on every call (including the common second-call no-op path). **#6 (NIT): Verbose history-priming comment in initialize.js** - Trimmed the 16-line `handlePrimeInvokedSkills` block to a 5-line summary with `@see InitializedAgent.codeEnvAvailable` pointer. The canonical narrowing explanation lives on the type; the controller comment is just the ACL-vs-capability rationale. **Skipped:** - #3 (memory spec tests a mirror function): reviewer self-dismissed as a design tradeoff; the enum-literal pin already catches the highest-risk drift vector. - #4 (cross-repo contract for `createCodeExecutionTool`): user will explicitly install the latest `@librechat/agents` dev version once the companion PR publishes, so the version pin will be authoritative. - #7 (migration/deprecation note for self-hosters): out of scope per user direction — release notes handle this. Tests verified: 679 packages/api + 840 backend api tests pass. Typecheck + lint clean. * 🔧 chore: Update @librechat/agents version to 3.1.68-dev.1 across package-lock and package.json files This commit updates the version of the `@librechat/agents` package from `3.1.68-dev.0` to `3.1.68-dev.1` in the `package-lock.json` and relevant `package.json` files. This change ensures consistency across the project and incorporates any updates or fixes from the new version. |

⚙️ feat: Skill runtime integration: catalog, tools, execution, file priming (#12649)
* feat: Skill runtime integration — catalog injection, tool registration, execute handler
Wires the @librechat/agents SkillTool primitive into LibreChat's agent runtime:
**Enums:**
- Add `skills` to AgentCapabilities + defaultAgentCapabilities
**Data layer:**
- Add `getSkillByName(name, accessibleIds)` — compound query that
combines name lookup + ACL check in one findOne
**Agent initialization (packages/api/src/agents/initialize.ts):**
- Accept `accessibleSkillIds` param and `listSkillsByAccess` db method
- Query accessible skills, format catalog via `formatSkillCatalog()`,
append to `additional_instructions` (appears in agent system prompt)
- Register `SkillToolDefinition` + `createSkillTool()` when catalog
is non-empty (tool appears in model's tool list)
- Store `accessibleSkillIds` and `skillCount` on InitializedAgent
**Execute handler (packages/api/src/agents/handlers.ts):**
- Add `getSkillByName` to `ToolExecuteOptions`
- `handleSkillToolCall()` intercepts `Constants.SKILL_TOOL`:
extracts skillName, loads body from DB with ACL check,
substitutes $ARGUMENTS, returns ToolExecuteResult with
injectedMessages (skill body as isMeta user message)
**Caller wiring:**
- initialize.js: query skill IDs via findAccessibleResources,
pass to initializeAgent + store on agentToolContexts,
add getSkillByName to toolExecuteOptions,
pass accessibleSkillIds through loadTools configurable
- openai.js + responses.js: same pattern for their flows
Requires @librechat/agents >= 3.1.65 (PR #91 exports).
* feat: Skills toggle in tools menu + backend capability gating
Frontend:
- Add skills?: boolean to TEphemeralAgent type
- Add LAST_SKILLS_TOGGLE_ to LocalStorageKeys for persistence
- Add skillsEnabled to useAgentCapabilities hook
- Add skills useToolToggle to BadgeRowContext with localStorage init
- New Skills.tsx badge component (Scroll icon, cyan theme,
permission-gated via PermissionTypes.SKILLS)
- Add skills entry to ToolsDropdown with toggle + pin
- Render Skills badge in BadgeRow ephemeral section
Backend:
- Extract injectSkillCatalog() into packages/api/src/agents/skills.ts
(reduces initializeAgent module size, reusable helper)
- initializeAgent delegates to helper instead of inline block
- Capability-gate the findAccessibleResources query:
- Agents endpoint: checks AgentCapabilities.skills in admin config
- OpenAI/Responses controllers: checks ephemeralAgent.skills toggle
- ACL query runs once per run, result shared across all agents
* refactor: remove createSkillTool() instance from injectSkillCatalog
SkillTool is event-driven only. The tool definition in toolDefinitions
is sufficient for the LLM to see the tool schema. No tool instance is
needed since the host handler intercepts via ON_TOOL_EXECUTE before
tool.invoke() is ever called.
Removes tools from InjectSkillCatalogParams/Result, drops the
createSkillTool import.
* feat: skill file priming, bash tool, and invoked skills state
Multi-file skill support:
- New primeSkillFiles() helper (packages/api/src/agents/skillFiles.ts)
uploads skill files + SKILL.md body to code execution environment
- handleSkillToolCall primes files on invocation when skill.fileCount > 0,
returns session info as artifact so ToolNode stores the session
- Skill-primed files available to subsequent bash/code tool calls
Bash tool auto-registration:
- BashExecutionToolDefinition added alongside SkillToolDefinition when
skills are enabled, giving the model a bash tool for running scripts
Conversation state:
- Add invokedSkillIds field to conversation schema (Mongoose + Zod)
- handleSkillToolCall updates conversation with $addToSet on success
- Enables re-priming skill files on subsequent runs (future)
Dependency wiring:
- Pass listSkillFiles, getStrategyFunctions, uploadCodeEnvFile,
updateConversation through ToolExecuteOptions
- Pass req and codeApiKey through mergedConfigurable
- All three controller entry points wired (initialize.js, openai.js,
responses.js)
* fix: load bash_tool instance in loadToolsForExecution, remove file listing
- Add createBashExecutionTool to loadToolsForExecution alongside PTC/ToolSearch
pattern: loads CODE_API_KEY, creates bash tool instance on demand
- Add BASH_TOOL and SKILL_TOOL to specialToolNames set so they don't go
through the generic loadTools path (bash is created here, skill is
intercepted in handler before tool.invoke)
- Remove file name listing from skill content text — it's the skill
author's responsibility to disclose files in SKILL.md, not the framework
* feat: batch upload for skill files, replace sequential uploads
- Add batchUploadCodeEnvFiles() to crud.js: single POST to /upload/batch
with all files in one multipart request, returns shared session_id
- Rewrite primeSkillFiles to collect all streams (SKILL.md + bundled files)
then do one batch upload instead of N sequential uploads
- Replace uploadCodeEnvFile with batchUploadCodeEnvFiles across all callers
(handlers.ts, initialize.js, openai.js, responses.js)
* refactor: remove invokedSkillIds from conversation schema
Skills aren't re-loaded between runs, so conversation-level state for
invoked skills doesn't help. Skill state will live on messages instead
(like tool_search discoveredTools and summaries), enabling in-place
re-injection on follow-up runs.
Removes invokedSkillIds from: convo Mongoose schema, IConversation
interface, Zod schema, ToolExecuteOptions.updateConversation, and
all three caller wiring points.
* feat: smart skill file re-priming with session freshness checking
Schema:
- Add codeEnvIdentifier field to ISkillFile (type + Mongoose schema)
- Add updateSkillFileCodeEnvIds batch method (uses tenantSafeBulkWrite)
- Export checkIfActive from Code/process.js
Extraction:
- Add extractInvokedSkillsFromHistory() to run.ts — scans message
history for AIMessage tool_calls where name === 'skill', extracts
skillName args. Follows same pattern as extractDiscoveredToolsFromHistory.
Smart re-priming in primeSkillFiles:
- Before batch uploading, checks if existing codeEnvIdentifiers are
still active via getSessionInfo + checkIfActive (23h threshold)
- If session is still active, returns cached references (zero uploads)
- If stale or missing, batch-uploads everything and persists new
identifiers on SkillFile documents (fire-and-forget)
- Single session check covers all files (batch shares one session_id)
Wiring:
- Pass getSessionInfo, checkIfActive, updateSkillFileCodeEnvIds
through ToolExecuteOptions and all three controller entry points
* feat: wire skill file re-priming at run start via initialSessions
Flow:
1. initialize.js creates primeInvokedSkills callback with all deps
2. client.js calls it with message history before createRun
3. extractInvokedSkillsFromHistory scans for skill tool calls
4. For each invoked skill with files, primeSkillFiles uploads/checks
5. Returns initialSessions map passed to createRun
6. createRun passes initialSessions to Run.create (via RunConfig)
7. Run constructor seeds Graph.sessions, making skill files available
to subsequent bash/code tool calls via ToolNode session injection
Requires @librechat/agents with initialSessions on RunConfig (PR #94).
* refactor: use CODE_EXECUTION_TOOLS set for code tool checks
Import CODE_EXECUTION_TOOLS from @librechat/agents and replace inline
constant checks in handlers.ts and callbacks.js. Fixes missing bash
tool coverage in the session context injection (handlers.ts) and code
output processing (callbacks.js).
* refactor: move primeInvokedSkills to packages/api, add skill body re-injection
Moves primeInvokedSkills from an inline closure in initialize.js (with
dynamic requires) to a proper exported function in packages/api
skillFiles.ts with explicit typed dependencies.
Key changes:
- primeInvokedSkills now returns both initialSessions (for file priming)
AND injectedMessages (skill bodies for context continuity)
- createRun accepts invokedSkillMessages and appends skill bodies to
systemContent so the model retains skill instructions across runs
- initialize.js calls the packaged function with all deps passed explicitly
- client.js passes both initialSessions and injectedMessages to createRun
* fix: move dynamic requires to top-level module imports
Move primeInvokedSkills, getStrategyFunctions, batchUploadCodeEnvFiles,
getSessionInfo, and checkIfActive from inline requires to top-level
module requires where they belong.
* refactor: skill body reconstruction via formatAgentMessages, not systemContent
Replaces the lazy systemContent approach with proper message-level
reconstruction:
SDK (formatAgentMessages):
- New invokedSkillBodies param (Map<string, string>)
- Reconstructs HumanMessages after skill ToolMessages at the correct
position in the message sequence, matching where ToolNode originally
injected them
LibreChat:
- extractInvokedSkillsFromPayload replaces extractInvokedSkillsFromHistory
(works with raw TPayload before formatAgentMessages, not BaseMessage[])
- primeInvokedSkills now takes payload instead of messages, returns
skillBodies Map instead of injectedMessages
- client.js calls primeInvokedSkills BEFORE formatAgentMessages, passes
skillBodies through as the 4th param
- Removed invokedSkillMessages from createRun (no more systemContent hack)
- Single-pass: skill detection happens inside formatAgentMessages' existing
tool_call processing loop, zero extra message iterations
* refactor: rename skillBodies to skills for consistency with SDK param
* refactor: move auth loading into primeInvokedSkills, pass loadAuthValues as dep
The payload/accessibleSkillIds guard and CODE_API_KEY loading now live
inside primeInvokedSkills (packages/api) rather than in the CJS caller.
initialize.js passes loadAuthValues as a dependency and the callback
is only created when skillsCapabilityEnabled.
* feat: ReadFile tool + conditional bash registration + skill path namespacing
ReadFile tool (read_file):
- General-purpose file reader, event-driven (ON_TOOL_EXECUTE)
- Schema: { file_path: string } — "{skillName}/{path}" convention
- handleReadFileCall: resolves skill name from path, ACL check, reads
from DB cache or storage, binary detection, size limits (256KB),
lazy caching (512KB), line numbers in output
- SKILL.md special case: reads skill.body directly
- Dispatched alongside SKILL_TOOL in createToolExecuteHandler
- Added to specialToolNames in ToolService
Conditional tool registration:
- ReadFile + SkillTool: always registered when skills enabled
- BashTool: only registered when codeEnvAvailable === true
- codeEnvAvailable passed through InitializeAgentParams from caller
Skill file path namespacing:
- primeSkillFiles now uploads as "{skillName}/SKILL.md" and
"{skillName}/{relativePath}" instead of flat names
- Prevents file collisions when multiple skills are invoked
Wiring:
- getSkillFileByPath + updateSkillFileContent passed through
ToolExecuteOptions in all three callers
* feat: return images/PDFs as artifacts from read_file, tighten caching
Binary artifact support:
- Images (png, jpeg, gif, webp) returned as base64 in artifact.content
with type: 'image_url', processed by existing callback attachment flow
- PDFs returned as base64 artifact similarly
- Binary size limit: 10MB (MAX_BINARY_BYTES)
- Other binary files still return metadata + bash fallback
Caching:
- Text cached only on first read (file.content == null check)
- Binary flag cached only on first detection (file.isBinary == null)
- Skill files are immutable; no redundant cache writes
Registration:
- ReadFileToolDefinition now includes responseFormat: 'content_and_artifact'
* chore: update @librechat/agents to version 3.1.66-dev.0 and add peer dependencies in package-lock.json and package.json files
* fix: resolve review findings #1,#2,#4,#5,#6,#10,#13
Critical:
- #1: primeInvokedSkills now accumulates files across all skills into
one session entry instead of overwriting. Parallel processing via
Promise.allSettled.
- #2: codeEnvAvailable now computed and passed in openai.js and
responses.js (was missing, bash tool never registered in those flows)
Major:
- #4: relativePath in updateSkillFileCodeEnvIds now strips the
{skillName}/ prefix to match SkillFile documents. SKILL.md filter
uses endsWith instead of exact match.
- #5: File priming guarded on apiKey being non-empty (skip when not
configured instead of failing with auth error)
- #6: Skills processed in parallel via Promise.allSettled instead of
sequential for-of loop
Minor:
- #10: Use top-level imports in initialize.js instead of inline requires
- #13: Log warning when skill catalog reaches the 100-skill limit
* fix: resolve followup review findings N1,N2,N4
N1 (CRITICAL): Wire skill deps into responses.js non-streaming path.
Was completely missing getSkillByName, file strategy functions, etc.
N2 (MAJOR): Single batch upload for ALL skills' files. Resolves skills
in parallel (Phase 1), then collects all file streams across skills
and does ONE batchUploadCodeEnvFiles call (Phase 2). All files share
one session_id, eliminating cross-session isolation issues.
N4 (MINOR): Move inline require() to top-level in openai.js and
responses.js, consistent with initialize.js.
* fix: add mocks for new file strategy imports in controller tests
* fix: restore session freshness check, parallelize file lookups, add warnings
R1: Re-add session freshness check before batch upload. Checks any
existing codeEnvIdentifier via getSessionInfo + checkIfActive. If the
session is still active (23h window), returns cached file references
with zero re-uploads.
R2: listSkillFiles calls parallelized via Promise.all (were sequential
in the for-of loop).
R3: Log warning when skill record lookup fails during identifier
persistence (was a silent empty-string fallback).
* fix: guard freshness cache on single-session consistency
* fix: multi-session freshness check (code env handles mixed sessions natively)
The code execution environment fetches each file by its own
{session_id, fileId} pair independently — no single-session
requirement. Removed the sessionIds.size === 1 guard.
Now checks ALL distinct sessions for freshness. If every session
is still active (23h window), returns cached references with per-file
session_ids preserved. If any session expired, falls through to
re-upload everything in a single batch.
* perf: parallelize session freshness checks via Promise.all
* fix: add optional chaining for session info retrieval in primeInvokedSkills
Updated the primeInvokedSkills function to use optional chaining for getSessionInfo and checkIfActive methods, ensuring safer access and preventing potential runtime errors when these methods are undefined.
* fix: address review findings #1-#9 + Codex P1/P2 + session probe
Critical:
- #1/Codex P1: Add codeApiKey loading to openai.js and responses.js
loadTools configurable (was missing, file priming broken in 2/3 paths)
- Codex P1: Fix cached file name prefix in primeSkillFiles cache path
(was sf.relativePath, now ${skill.name}/${sf.relativePath})
Major:
- Codex P2: Honor ephemeral skills toggle in agents endpoint
(check ephemeralAgent?.skills !== false alongside admin capability)
- #4: Early size check using file.bytes from DB before streaming
(prevents full-file buffer for oversized files)
Minor:
- #5: Replace Record<string, any> with Record<string, boolean | string>
- #6: Localize Pin/Unpin aria-labels with com_ui_pin/com_ui_unpin
- #8: Parallelize stream acquisition in primeSkillFiles via
Promise.allSettled
- #9: Log warning for partial batch upload failures with filenames
Performance:
- Session probe optimization: getSessionInfo now hits per-object
endpoint (GET /sessions/{sid}/objects/{fid}) instead of listing
entire session (GET /files/{sid}?detail=summary). O(1) stat vs
O(N) list + linear scan.
* refactor: extract shared skill wiring helper + add unit tests
DRY (#3):
- New skillDeps.js exports getSkillToolDeps() with all 9 skill-related
deps (getSkillByName, listSkillFiles, getStrategyFunctions, etc.)
- Replaces 5 identical copy-paste blocks across initialize.js, openai.js,
responses.js (streaming + non-streaming paths)
- One place to maintain when skill deps change
Tests (#2):
- 8 unit tests for extractInvokedSkillsFromPayload covering:
string args, object args, missing skill tool_calls, non-assistant
messages, malformed JSON, empty skillName, empty payload, dedup
* fix: remove @jest/globals import, use global jest env
* fix: resolve round 2 review findings R2-1 through R2-7
R2-1 (toggle semantics): openai.js + responses.js now check admin
capability (AgentCapabilities.skills) alongside ephemeral toggle.
Aligns with initialize.js.
R2-2 (swallowed error): primeInvokedSkills now logs
updateSkillFileCodeEnvIds failures (was .catch(() => {}))
R2-4 (test cast): Record<string, string> → Record<string, unknown>
R2-5 (DRY regression): Extract enrichWithSkillConfigurable() into
skillDeps.js. Replaces 4 identical loadAuthValues blocks.
Each loadTools callback is now a one-liner. JSDoc added (R2-6).
R2-7 (sequential streams): primeInvokedSkills now uses
Promise.allSettled for parallel stream acquisition.
* fix: require explicit skills toggle + treat partial cache as miss
- initialize.js: change ephemeralSkillsToggle !== false to === true
(unset toggle no longer enables skills)
- primeSkillFiles cache: require ALL files to have codeEnvIdentifier
before using cache (partial persistence = cache miss = re-upload)
- primeInvokedSkills cache: same check (allFilesWithIds.length must
equal total file count)
* fix: pass entity_id=skillId on batch upload, eliminates per-user cache thrashing
primeSkillFiles now passes entity_id: skill._id.toString() to
batchUploadCodeEnvFiles. This scopes the code env session to the
skill, not the user. All users sharing a skill share the same
uploaded files — no more cache thrashing from overwriting each
other's codeEnvIdentifier.
The stored codeEnvIdentifier now includes ?entity_id= suffix so
freshness checks pass the entity_id through to the per-object
stat endpoint. Both primeSkillFiles and primeInvokedSkills
store consistent identifier formats.
* fix: pass entity_id on multi-skill batch upload, consistent identifier format
* Revert "fix: pass entity_id on multi-skill batch upload, consistent identifier format"

📜 feat: Skills UI + Initial E2E CRUD / Sharing (#12580)
* 🎨 feat: Skills UI — Create/Edit/Share/List with Conditional File Tree First-pass UI on top of the CRUD API scaffolding (#12613). Ships the full user-facing flow for inline, single-SKILL.md skills and leaves a clean drop-in for phase-2 multi-file support. - Create a skill from /skills/new with name (kebab-case, validated), description, and SKILL.md body — wired to the real `useCreateSkillMutation` and `TCreateSkill` payload. - List skills in a sidebar (SkillsSidePanel) via `useListSkillsQuery` with live search filtering. - Edit any skill the caller has EDIT permission on — `useUpdateSkillMutation` passes `expectedVersion` for optimistic concurrency and surfaces 409 conflicts as a warning toast + cache refetch. - Non-blocking `TSkillWarning[]` (e.g. "description too short") are shown inline above the form after a successful create/patch. - Read-only mode when the current user lacks EDIT — the form still renders but inputs are marked `readOnly` and the save/reset buttons are hidden. - Share via ACL using the existing `GenericGrantAccessDialog` — the `ShareSkill` button is gated on the SHARE permission. - Delete with confirmation, driven by `useDeleteSkillMutation({ id })`. - Conditional file tree: only rendered when `useListSkillFilesQuery` returns > 0 files. The tree groups flat `relativePath` strings into a nested view (no `react-arborist` dependency) and supports per-file deletion via `useDeleteSkillFileMutation`. Upload is intentionally deferred — the backend stubs it at 501 in phase 1. - New routes: `/skills`, `/skills/new`, `/skills/:skillId`. - Sidebar accordion (`SkillsAccordion` wrapping `SkillsSidePanel`) added to `useSideNavLinks` gated on `PermissionTypes.SKILLS` USE. The initial UI branch (#12580) shipped a lot of exploration code on top of a now-superseded placeholder backend. Kept as complementary: the `Skills/` component tree, translation keys, role descriptions, `PublicSharingToggle` SKILL mapping, `resources.ts` SKILL config, `useCanSharePublic` SKILL mapping, and `data-provider/roles.ts` `useUpdateSkillPermissionsMutation`. Deferred out of this first pass: - Skill favorites (`useSkillFavorites`, `getSkillFavorites` endpoint) — the backend route doesn't exist yet; saving for a follow-up. - AgentConfig `SkillSelectDialog` integration — the UI branch had this gated behind `false &&`; rolled back with the config. - `InvocationMode` / `CategorySelector` / `parseSkillMd` / tree-node mutations — not in the Anthropic skill spec and not in the CRUD API. - `react-arborist` dependency — replaced with a hand-rolled recursive tree built from flat `TSkillFile[]`. - 38 data-schemas skill model tests: pass - 25 api skill route tests: pass - 16 user-controller cleanup tests: pass * 🔐 feat: Default-On Skills in Interface Config and Role Seeder The skills accordion was registered in the side nav gated on `PermissionTypes.SKILLS` USE, but no one was actually seeding that permission on startup, so a fresh install had the USER role with zero skill permissions and the accordion never rendered. Fixes three gaps: 1. `interfaceSchema` in data-provider's `config.ts` had no `skills` field at all. Added it alongside the existing agents/prompts shape (boolean | { use, create, share, public }) and a default of `{ use: true, create: true, share: false, public: false }`. 2. `loadDefaultInterface` in data-schemas passed every interface key through to the loaded config EXCEPT `skills`. Added the one-line passthrough so `appConfig.interfaceConfig.skills` is actually populated on boot. 3. `updateInterfacePermissions` in packages/api/src/app/permissions.ts seeds role permissions from the interface config on every restart. Added: - `SKILLS` case to `hasExplicitConfig` - `skillsDefaultUse/Create/Share/Public` extraction (mirrors prompts/agents) - `PermissionTypes.SKILLS` block in `allPermissions` that falls through config → roleDefaults → schema default, same pattern as AGENTS and PROMPTS - `SKILLS` entry in the share-backfill array so that pre-existing SKILL role docs missing SHARE/SHARE_PUBLIC get them filled on the next restart Test expectations updated: seven `expectedPermissionsFor(User|Admin)` blocks in `permissions.spec.ts` now include SKILLS, matching the role-default values (USER: use+create true, share/public false; ADMIN: all true). Result: on a fresh install, a regular USER gets skill USE/CREATE and the "Skills" accordion shows up in the chat side panel without any yaml config. Admins can lock it down per role or per tenant via `interface.skills` in librechat.yaml. Tests: - 34 packages/api permissions.spec.ts: pass - 151 packages/api app tests: pass - 38 data-schemas skill.spec.ts: pass - 928 data-provider tests: pass - 25 api skills.test.js: pass * ♻️ fix: Resolve Skills UI Review Findings Addresses the 13 findings from the PR review against the prior commit. 1. **canEdit consistency** — extracted `useSkillPermissions(skill)` as the single source of truth for owner/admin/ACL gating. `SkillsView`, `SkillForm`, `ShareSkill` all consume it; `SkillFileTree`'s per-file delete button now honors admin + EDIT-bit permissions instead of just ownership. Unit tests cover owner, admin, editor-ACL, viewer-ACL, owner-ACL, loading, and undefined-skill cases. 2. **Disabled submit buttons** — create/edit form submit buttons now set native `disabled` (not just `aria-disabled`) during `isLoading`. `onSubmit` also guards with an early return when the mutation is still in-flight so a duplicate enter-key submit can't create two skills. 3. **Wrong maxLength error message** — description/name `maxLength` rules no longer re-use `com_ui_skill_*_required`. Added dedicated `com_ui_skill_name_too_long` and `com_ui_skill_description_too_long` keys with the literal limit interpolated (`{{0}}`). 4. **Search debouncing** — `SkillsSidePanel` now threads the filter input through the existing `useDebounce` hook (250ms) so typing "skills" no longer fires six separate list queries. 5. **Frontend test coverage** — added: - `tree.test.ts` (9 tests) covering `buildTree` / `nodeKey` edge cases: empty input, single root file, multiple roots, nested folders, deeply-nested trees, lexicographic sort, empty paths, stable keys - `useSkillPermissions.test.ts` (7 tests) covering every precedence branch (owner / admin / EDIT / VIEW / owner-ACL / loading / undef) Form integration tests proved flaky against react-hook-form's async `isValid` with our jest-dom mock setup; deferred to a follow-up PR with a proper `@librechat/client` test harness. 6. **Shared `SKILL_NAME_PATTERN`** — promoted the regex plus the four length constants (`SKILL_NAME_MAX_LENGTH`, `SKILL_DESCRIPTION_MAX_LENGTH`, `SKILL_DESCRIPTION_SHORT_THRESHOLD`, `SKILL_DISPLAY_TITLE_MAX_LENGTH`, `SKILL_BODY_MAX_LENGTH`) out of `packages/data-schemas/src/methods/skill.ts` and into `packages/data-provider/src/types/skills.ts`. The data-schemas module now aliases the shared exports so the backend validator and the frontend form share one source of truth. Also fixed a latent bug: the client regex was stricter than the backend (`^[a-z0-9]+(?:-[a-z0-9]+)*$` vs. the real `^[a-z0-9][a-z0-9-]*$`), which would have rejected valid names like `foo--bar` client-side. 7. **Removed hardcoded "Claude"** — replaced `com_ui_skill_description_help` ("Claude uses this to...") with a new `com_ui_skill_create_subtitle` for the form header and `com_ui_skill_description_field_hint` ("This is what the model reads to decide...") for the inline hint. LibreChat is LLM-agnostic; the old copy misled GPT/Gemini users. 8. **Lifted tree mutation hook** — `useDeleteSkillFileMutation` is now instantiated once in `SkillFileTree` (not per `TreeRow`). A `TreeContext` provides `onDeleteFile` + `isDeleting` + `canEdit` to rows. A 60-node tree used to instantiate 60 mutation hooks; it now instantiates one. 9. **List O(n) re-render** — `SkillListItem` no longer reads `useParams()` directly. `SkillList` reads the active id once and passes `isActive` as a prop, so navigation only re-renders the two items whose `isActive` flipped (memo'd), not all N items. 10. **Deduped help text** — the field-level hint and form-level subtitle now use different translation keys with distinct copy instead of showing the same sentence twice on the same page. 11. **Removed ineffective `useCallback`** — `DeleteSkill.handleDelete`, `CreateSkillForm.onSubmit` / `.handleCancel`, `SkillForm.onSubmit`, and `SkillFileTree.handleDeleteFile` all wrapped closures around React Query `mutation` refs, whose identities change every render. Their dep arrays invalidated every render, making the memo a no-op with extra overhead. `SkillFileTree` now destructures the stable `mutate` function and inlines the arrow inside the memoized `contextValue` — one stable reference per deps change. 12. **Import order** — fixed shortest→longest package ordering and longest→shortest local ordering across all touched skill files per AGENTS.md. `react` always first where imported. 13. **Memoization principle** — documented the rule with inline comments: `memo` on components that appear in repeated contexts (`TreeRow`, `SkillListItem`) or as children of frequently-re-rendering parents (`ShareSkill` / `DeleteSkill` under `SkillForm`'s per-keystroke form-state updates). Removed `memo` from `SkillFileTree` since its parent `SkillDetailPanel` only re-renders on query-data changes. - 38 data-schemas skill.spec.ts - 34 packages/api permissions.spec.ts - 25 api skills.test.js - 16 client unit tests (9 buildTree + 7 useSkillPermissions) - All type-checks + eslint clean on touched files * 🧹 fix: Skills Duplication, Input Styling, Remove LLM-specific Copy Three UI fixes from an in-chat review pass: 1. **Sidebar duplication** — `SkillsView` was rendering its own `SkillsSidePanel` aside alongside the chat side panel's `SkillsAccordion`, so on `/skills` the user saw the skill list twice. Fixed by mirroring the `InlinePromptsView` pattern: the route content is now just the detail / create panel and the chat side panel is the sole list. Added `/skills → /skills/new` redirect and a `/skills/new` literal route so `useParams().skillId` is `undefined` for "new" (matches prompts). 2. **Name Input styling** — the big floating-label pattern used by prompts/agents for the primary name field was replaced with a conventional `<Label>` + `<Input>` above it, diverging from the rest of the app. Restored the prompts-style `text-2xl` input with the peer-focus animated label on both `CreateSkillForm` and `SkillForm`. Kept the conventional pattern for description and body since they're textareas. 3. **Remove LLM-specific copy from skill translations** — dropped `com_ui_skill_description_help` ("Claude uses this to...") and the transitional "This is what the model reads..." phrasing. Field hint is now a neutral "Be specific about when this skill should apply." and the create-page subtitle is a neutral "Author a new skill your agents can invoke." LibreChat is LLM-agnostic; baking product names into user-facing copy is wrong outside the `com_endpoint_anthropic_*` keys where the setting actually only applies to Claude models. Side-effect: the `SkillDetailView` wrapper in `SkillsView` now only renders the file-tree aside when the skill has > 0 files — same conditional-tree behavior as before, just scoped to this route instead of also trying to also render a list sidebar. - 16 client skill tests still pass - Type-check + eslint clean on touched files * 🎁 feat: Restore Skills UI from PR #12580 Brings back everything the original UI PR (#12580, commit da039917c) shipped that my earlier rebase dropped. Verbatim restores where possible; adapts the new hooks/types where the backend contract has shifted. **Scoped-out / gated-off (now restored as inert UI scaffolding):** - `hooks/useSkillFavorites.ts` + `utils/favoritesError.ts` + the `useGetSkillFavoritesQuery` / `useUpdateSkillFavoritesMutation` additions in `data-provider/Favorites.ts`. The backend route doesn't exist yet — the data-service functions resolve with empty arrays so the Star UI is a visual-only no-op until phase 2. - `dialogs/SkillSelectDialog.tsx` + the "Add Skills" section in `SidePanel/Agents/AgentConfig.tsx` (still gated behind the original `false &&`) + `skills?: string[]` on `AgentForm` / `Agent` / `AgentCreateParams` / `AgentUpdateParams` + the `skills: []` entry in `defaultAgentFormValues`. - `TUserFavorite.skillId` reserved on the shared favorites type. **Concept-is-gone / deleted-types (restored as UI-only types + stubs):** - `InvocationMode` enum and `TSkillNode`, `TSkillTreeResponse`, `TCreateSkillNodeRequest`, `TUpdateSkillNodeRequest` types in `packages/data-provider/src/types.ts`. UI-facing only; the backend flat `TSkillFile[]` contract is unchanged. - `TSkill.invocationMode?: InvocationMode` as an optional field. Forms read/write it in local state and deliberately drop it from the PATCH payload until the backend column lands. - `tree/SkillFileTree.tsx` (`react-arborist`-based), `SkillTreeNode.tsx`, `TreeToolbar.tsx`, `SkillFileEditor.tsx`, `SkillFilePreview.tsx` — full filesystem-style browser UI restored verbatim. - `data-provider/Skills/tree-queries.ts` + `tree-mutations.ts` hooks (`useGetSkillTreeQuery`, `useCreateSkillNodeMutation`, etc.). The `data-service` stubs them: `getSkillTree` returns `{ nodes: [] }`, `createSkillNode` / `updateSkillNode` / `updateSkillNodeContent` return synthetic node shapes, `deleteSkillNode` resolves void. Hooks compile and run; tree is empty until phase 2 wires a real backend. - `MutationKeys.createSkillNode` / `updateSkillNode` / `deleteSkillNode` / `updateSkillNodeContent` + `CreateSkillNodeBody` / `UpdateSkillNodeVariables` / `DeleteSkillNodeBody` / `UpdateSkillNodeContentVariables` types. - `QueryKeys.skillTree` / `skillNodeContent` / `skillFavorites` / `favorites` and the `skillTree()` endpoint helper. **Scope-simplified (restored with minimal adaptation):** - `display/SkillDetailHeader.tsx` + `display/SkillDetail.tsx`. Header now falls back to `InvocationMode.auto` when `skill.invocationMode` is undefined. - `forms/SkillContentEditor.tsx` — click-to-edit markdown preview toggle for the SKILL.md body field. Wired into both `CreateSkillForm` and `SkillForm` replacing the plain `<TextareaAutosize>`. (Needed `@ts-ignore` on `remarkPlugins` / `rehypePlugins` for the same `PluggableList` vs `Pluggable[]` shape drift `MarkdownLite.tsx` already works around.) - `forms/InvocationModePicker.tsx` + `forms/CategorySelector.tsx` — the auto/manual/both dropdown and the skill category selector. Wired into both forms inside a `FormProvider` so the Controller-based widgets can read `useFormContext`. `category` flows to the PATCH / POST payload as before; `invocationMode` is UI-only per the type note above. - `buttons/CreateSkillMenu.tsx` + `utils/parseSkillMd.ts` — dropdown with AI / Manual / Upload SKILL.md entries + the YAML frontmatter parser for the upload path. `CreateSkillForm.defaultValues` now accepts the parsed shape, so the upload → redirect → pre-populated form flow works again. - `buttons/AdminSettings.tsx` — admin permissions dialog. Uses the existing `useUpdateSkillPermissionsMutation` which was already wired. - `sidebar/FilterSkills.tsx` — restored filter + AdminSettings + CreateSkillMenu wrapper. `SkillsSidePanel.tsx` is back to the original `FilterSkills`-based layout. - `lists/SkillList.tsx` + `lists/SkillListItem.tsx` — restored verbatim. - `layouts/SkillsView.tsx` — restored the full tree + file editor + file preview layout. The chat side panel keeps its own accordion list; this view is the inline detail experience. - `hooks/Generic/useUnsavedChangesPrompt.ts` — route-leave guard hook. - `useGetSkillByIdQuery` is aliased to `useGetSkillQuery` so restored components (`SkillsView`, `SkillForm`) that import the old name resolve to the new hook. - `SkillSelectDialog` + `AgentConfig` coerce `skillsData?.skills` instead of `.data` (list response shape drift from the CRUD PR). - `CreateSkillForm` / `SkillForm` wrap their JSX in `FormProvider` so the restored `CategorySelector` and `SkillContentEditor` components — which read `useFormContext` — work inside the existing forms without another refactor. - `CreateSkillForm.defaultValues` prop accepts `Partial<Values> & { invocationMode?: unknown }` so the upload flow's `{ name, description, invocationMode }` shape passes through cleanly. - `SkillsView` route map gains `/skills/:skillId/edit` and `/skills/:skillId/file/:nodeId` so the tree-navigation URLs the original view produces actually resolve. - `client/package.json` gains `react-arborist@^3.4.3`. - ~60 translation keys the restored files reference — invocation labels, edit/create page titles, file editor chrome, tree toolbar tooltips, favorites, admin allow-settings, unknown-file-type, sr_public_skill, delete/rename _var variants — all added to `en/translation.json`. - Prompts-style floating-label name input — kept from my earlier commit so it matches the rest of the app (user reviewed and approved that styling). Hidden skill-body textarea is replaced by `SkillContentEditor` in both forms. - 38 data-schemas skill.spec.ts - 34 packages/api permissions.spec.ts - 25 api skills.test.js - 7 client useSkillPermissions.test.ts - Type-check: pre-existing error count (188) dropped to 120 because my restorations fixed some previously-broken field types. * chore: Update package-lock.json to include react-arborist and memoize-one * feat: Add support for react-arborist in Vite configuration This update introduces a new condition in the Vite configuration to handle the 'react-arborist' package, ensuring it is properly recognized during the build process. This change enhances compatibility with the recently added 'react-arborist' dependency in the project. * 🩹 fix: Hide InvocationMode, Fix SkillContentEditor Click-to-Edit 1. Hide InvocationModePicker from both CreateSkillForm and SkillForm. Component stays on disk for when the backend lands the column. 2. Fix "Click to edit" doing nothing on SkillContentEditor. The `onBlur={() => setIsEditing(false)}` on the TextareaAutosize was racing with `autoFocus` — React renders the textarea, autoFocus fires, then a layout/reconciliation blur fires immediately, bouncing back to preview mode before the user can interact. Removed onBlur; users toggle via the header button or Escape key. * 🎨 feat: Reader-First Skills UI — Match Claude.ai Layout Reworks the Skills UI from form-first to reader-first, matching Claude.ai's skill detail pattern. **Default view is now read-only.** Clicking a skill in the sidebar navigates to `/skills/:id` which renders `SkillDetail` — a clean content view with: - Skill name as the primary heading - Metadata row: "Added by" + "Last updated" (formatted date) - Description block - Rendered SKILL.md body in a bordered card with a source/rendered toggle (eye + code icons, matching Claude.ai's segmented control) No form fields, no save/cancel buttons. The user reads the skill first and takes action deliberately. **Create is now a dialog.** The `/skills/new` route is gone. `CreateSkillMenu` (the + dropdown in the sidebar) now opens `CreateSkillDialog` — a minimal modal with name, description, and instructions fields. Upload-from-file still works: parse → populate dialog → create. Matches Claude.ai's "Write skill instructions" modal. **Edit is behind an action.** The detail view shows an "Edit" button (permission-gated) that navigates to `/skills/:id/edit`, rendering the existing `SkillForm`. The edit route is preserved for direct linking. **Navigation goes to detail, not edit.** `SkillListItem` now navigates to `/skills/:id` (detail) instead of `/skills/:id/edit`. - `display/SkillMarkdownRenderer.tsx` — shared ReactMarkdown component extracted from `SkillContentEditor`. Same remark/rehype plugins, no form dependency. - `display/SkillDetail.tsx` — the reader-first view (replaces the old thin wrapper). - `dialogs/CreateSkillDialog.tsx` — OGDialog modal for skill creation. - `layouts/SkillsView.tsx` — gutted and rebuilt. Three states: no-skill (empty state), skillId (SkillDetail), skillId+edit (SkillForm). Removed full-page CreateSkillForm, removed TreeView. - `buttons/CreateSkillMenu.tsx` — opens dialog instead of navigating to `/skills/new`. Upload flow: parse → set dialog defaults → open. - `lists/SkillListItem.tsx` — navigate to detail, not edit. - `routes/index.tsx` — removed `/skills/new` and file/nodeId routes; `/skills` renders SkillsView directly (empty state). - `display/index.ts`, `dialogs/index.ts` — added new exports. - `locales/en/translation.json` — added ~10 new keys for metadata, toggle labels, dialog title, empty state. * 🩹 fix: SkillContentEditor click-to-edit z-index — button was z-0 behind rendered content * 🩹 fix: Align Edit button size with Share/Delete (size-9) * 🎨 feat: Claude.ai-Style Skill List Panel Rewrites the skills sidebar to match Claude.ai's panel layout: - Header: "Skills" title + search icon (toggles input) + add icon (opens CreateSkillDialog directly, no dropdown menu) - Collapsible "Skills" section with chevron toggle - Skill items: 24px icon badge (rounded square with ScrollText icon) + name only. No description text in the list — that lives in the detail view. Active item gets highlighted bg + bold font. - Removed AdminSettings button from sidebar header — admin config is accessible via the admin dashboard, not cluttering every user's skill list. - Removed FilterSkills wrapper (was Filter + AdminSettings + CreateSkillMenu). The search + create are now inline in the panel header. Files changed: - sidebar/SkillsSidePanel.tsx — full rewrite - sidebar/SkillsAccordion.tsx — simplified wrapper - lists/SkillList.tsx — collapsible section, no description - lists/SkillListItem.tsx — icon badge + name, memo'd * 🎨 fix: Align Skills UI Styling with Prompts Patterns Style alignment pass based on direct comparison with claude.ai and the existing prompts preview dialog. SkillsSidePanel search now replaces the title in the header row when toggled (search icon + input + X close), matching Claude.ai's pattern. Previously it pushed a separate input below the header, wasting vertical space. Close button clears the search term. Replaced `text-text-tertiary` with `text-text-secondary` across SkillDetail, SkillList, SkillForm, CreateSkillForm, CreateSkillDialog, SkillContentEditor. Tertiary was too dark / low contrast. SkillList section chevron label now reads "Personal skills" (matching Claude.ai) via the existing `com_ui_my_skills` key, instead of the generic "Skills" which duplicated the header. Aligned with `PromptDetailHeader` styling: - 48px round icon (ScrollText in bg-surface-secondary circle) - Name + public badge in the icon row - Metadata below the icon: User icon + author, Calendar icon + date (text-xs text-text-secondary with gap-3, matching prompts exactly) - Description uses the same label-above-text pattern as prompts - Content card uses `bg-transparent` border (not bg-surface-primary-alt) - Toggle buttons use size-5 icons and text-text-secondary for inactive Changed from `max-w-lg p-0` to `max-w-5xl` with the same max-height and padding pattern as the prompts PreviewPrompt dialog: `max-h-[80vh] p-1 sm:p-2 gap-3 sm:gap-4`. Close button now renders via default OGDialogContent behavior (removed showCloseButton=false). * 🩹 fix: SkillDetail fills parent height, tighter spacing (px-6 pb-6 gap-2) * 🩹 fix: Align Skills panel header padding (px-4) with list content below * 🩹 fix: Reduce Skills header top padding (pt-2) to align with sidebar icon strip * 🩹 fix: Tighten Skills header (py-2) and detail top (py-2) to align with sidebar icons and match edit view * 🩹 fix: Offset SidePanel Nav pt-2 with -mt-2 on SkillsAccordion so Skills header aligns with icon strip * 🛠️ fix: Increase Node memory limit for production build in package.json * 🩹 fix: Remove top padding from SkillDetail header row (py-2 → pb-2) * 🏗️ refactor: Move pt-2 from SidePanel/Nav wrapper to each panel Removed the global `pt-2` from `SidePanel/Nav.tsx` and pushed it into each panel's own top-level wrapper. This lets each panel own its vertical alignment independently — Skills can sit flush at the top to align with the sidebar icon strip, while other panels keep their original spacing. Panels updated with `pt-2`: - PromptsAccordion (via className on PromptSidePanel) - BookmarkPanel - FilesPanel - MemoryPanel - MCPBuilderPanel - AgentPanel (form wrapper) - AssistantPanel (form wrapper) - ParametersPanel (already had pt-2) SkillsAccordion: removed the -mt-2 hack, now naturally flush. * 🧹 fix: Align CreateSkillDialog field styling + remove 19 unused i18n keys Dialog fields: all three inputs now use consistent `rounded-xl border-border-medium px-3 py-2 text-sm` styling. Replaced the `<Input>` component with a plain `<input>` to avoid the component's built-in `rounded-lg border-border-light` overriding the dialog's border style. Labels use `font-medium` for consistency. Removed 19 unused translation keys from translation.json: com_ui_skill_body, com_ui_skill_body_placeholder, com_ui_skill_create_subtitle, com_ui_skill_file_delete_confirm, com_ui_skill_file_delete_error, com_ui_skill_file_deleted, com_ui_skill_files_empty, com_ui_skill_files_multi_hint, com_ui_skill_list, com_ui_skill_load_error, com_ui_skill_resize_file_tree, com_ui_skill_select_file, com_ui_skill_select_file_desc, com_ui_skills_load_error, com_ui_add_first_skill, com_ui_create_skill_page, com_ui_edit_skill_page, com_ui_save_skill, com_ui_no_skills_title * 🎁 feat: Upload Skill Dialog + Simplified Create Menu New `UploadSkillDialog` matching Claude.ai's upload modal: - Dashed drop zone with drag-and-drop support - Accepts .md, .zip, .skill files - Phase 1: processes .md files (parses YAML frontmatter → creates skill with body as the full file content) - Shows file requirements below the drop zone - On success: navigates to the new skill's detail view `CreateSkillMenu` now has two flat options (no sub-menu): - "Write skill instructions" → opens `CreateSkillDialog` - "Upload a skill" → opens `UploadSkillDialog` Removed the disabled "Create with AI" option and the old file input hidden-element approach. The sidebar `+` button now renders `CreateSkillMenu` directly instead of a standalone create dialog. - Removed 5 unused i18n keys (com_ui_skill_added_by, com_ui_skill_last_updated, com_ui_skills_add_first, com_ui_skills_filter_placeholder, com_ui_skills_new) - Tightened metadata gap in SkillDetail (mt-1 → mt-0.5) - Added 7 new upload-related i18n keys * 🔒 feat: Zip/Skill File Upload Support with Safety Limits Rewrites UploadSkillDialog to properly handle all three accepted file types: - `.md` — reads as text, parses YAML frontmatter, creates skill - `.zip` / `.skill` — reads as ArrayBuffer, extracts with JSZip, finds SKILL.md (at root or one level deep), parses its content, creates skill. Shows spinner during processing. Security guards against zip bombs: - MAX_ZIP_SIZE: 50MB compressed file limit - MAX_ENTRIES: 500 file limit inside the archive - Path traversal rejection: skips entries with `..` or leading `/` - SKILL.md search limited to depth ≤ 2 segments Added `jszip@^3.10.1` to client dependencies (already in the monorepo's node_modules from backend usage). The name is inferred from the zip filename if SKILL.md frontmatter doesn't have one (e.g. `skills-autofix.zip` → `skills-autofix`). * 🚀 feat: Backend Skill Import + Live File Upload Endpoints New endpoint that accepts a single multipart file (.md, .zip, .skill) and creates a skill with all its files in one request: - **.md**: parse YAML frontmatter → create skill with body - **.zip / .skill**: extract with JSZip, find SKILL.md (root or one level deep), create skill from its content, then persist every additional file via `upsertSkillFile` + local file storage strategy. Returns the created skill + an `_importSummary` with per-file results. Security: - 50MB compressed file size limit (multer) - 500 max entries in archive - 10MB per individual file - Path traversal rejection (no `..`, no absolute, validated charset) - File type filter: only .md/.zip/.skill accepted - Rate limited via existing `fileUploadIpLimiter` + `fileUploadUserLimiter` Handler lives in `packages/api/src/skills/import.ts` with injectable deps (`createSkill`, `upsertSkillFile`, `saveBuffer`) for testability. Replaced the 501 stub with a real handler: - Accepts multipart FormData with `file` + `relativePath` - Saves file via local storage strategy - Calls `upsertSkillFile` to persist the SkillFile record - Returns the upserted document - Rate limited, ACL-gated (EDIT permission required) - 10MB per file limit `UploadSkillDialog` now sends the file to `/api/skills/import` via `dataService.importSkill(formData)` — no more client-side JSZip. Removed `jszip` from client dependencies (only backend needs it). Added `importSkill()` in data-service + `importSkill()` endpoint builder in api-endpoints. Updated the file upload test from expecting 501 stub to expecting 400 "no file provided" (live validation). All 25 skill route tests pass. * 🔒 fix: Complete Import Handler — Validation, Ownership, Error Surfacing Fixes several gaps in the skill import flow: 1. **Skill validation now runs and surfaces properly.** The import handler calls the real `createSkill(CreateSkillInput)` which runs `validateSkillName`, `validateSkillDescription`, `validateSkillBody`. Validation errors (SKILL_VALIDATION_FAILED) are caught and returned as 400 with the issue messages. Duplicate-key errors return 409. Previously all errors were swallowed into a generic 500. 2. **`authorName` is now populated.** The `CreateSkillInput` requires `authorName` which was missing — resolved from `req.user.name ?? req.user.username ?? 'Unknown'`, matching the existing create handler. 3. **SKILL_OWNER permission is granted after import.** Calls `grantPermission` with `AccessRoleIds.SKILL_OWNER` so the uploader can edit/delete/share the imported skill. This was entirely missing — imported skills would have been ownerless. 4. **`tenantId` propagated.** Both the skill and each SkillFile record receive `req.user.tenantId` for multi-tenant deployments. 5. **SkillFile records are created in the DB.** Each non-SKILL.md file in the zip is saved to file storage via `saveBuffer` and recorded via `upsertSkillFile`, which validates the relativePath, infers the category from the path prefix, and atomically bumps the skill's `fileCount` and `version`. Import deps now include `grantPermission` from PermissionService, injected in `api/server/routes/skills.js`. * 🐛 fix: Import grant uses accessRoleId (not roleId) — fixes skill not appearing in list * 🎨 fix: Cache invalidation, file tree, frontmatter rendering Three fixes for the skill detail view: 1. **Cache invalidation after import.** UploadSkillDialog now calls `queryClient.invalidateQueries([QueryKeys.skills])` after a successful import so the sidebar list picks up the new skill without requiring a page refresh. 2. **File tree in detail view.** When a skill has `fileCount > 0`, the detail view now queries `useListSkillFilesQuery` and renders a file list below the body card — SKILL.md first, then folders and root files. Icons: Folder for directories, FileText for files. 3. **Frontmatter stripped and rendered as metadata.** YAML frontmatter (`---\nversion: 0.1.0\ntriggers: ...\n---`) is now parsed out of the body before markdown rendering. The `name` and `description` fields are skipped (already shown in the header). Remaining fields (version, triggers, dependencies, etc.) are displayed in a Claude.ai–style grid: label on the left, value on the right, above the rendered markdown content. Source view still shows the full raw body including frontmatter. * 🩹 fix: Always fetch skill files — fileCount may be stale in cached skill object * 🌳 feat: Inline File Tree in Sidebar Skill List Moves the file tree from the bottom of SkillDetail into the sidebar list, matching Claude.ai's pattern: - Multi-file skills show a chevron toggle on the right side of the skill list item - Clicking the chevron expands an inline file tree below the skill name: SKILL.md first, then folders (with folder icon + right chevron) and root files - File list is fetched lazily (only when expanded) via useListSkillFilesQuery - Clicking a file navigates to the skill detail view - Files section removed from SkillDetail — the sidebar is now the sole file tree location, keeping the detail panel clean SkillDetail cleaned up: removed groupFiles helper, file-related state, useListSkillFilesQuery import, FileText/Folder icon imports. * 🌲 feat: Virtualized inline file tree with react-vtree Replace hand-rolled recursive FolderRow/FileRow buttons with a proper virtualized FixedSizeTree from react-vtree for the sidebar skill list. Dynamic height tracks open folders; capped at 350px with smooth expand/collapse transitions. * chore: Remove no longer used SkillFileTree and SkillTreeNode components * chore: Update Vite config to replace 'react-arborist' with 'react-vtree' for module resolution * feat: Skill file content viewing with lazy DB caching - Add `skills` field to `fileStrategiesSchema` so operators can configure a dedicated storage backend for skill files. Falls back by type (image/document) when unset. - Fix hardcoded `FileSources.local` in skill save/import — now uses the resolved strategy via `getFileStrategy(req.config, { context })`. - Replace 501 download stub with real handler that streams from any storage backend and returns JSON `{ content, mimeType, isBinary }`. - Binary detection (null-byte + non-printable ratio on first 8 KB) flags files on first read so they're never re-fetched. - Text content ≤ 512 KB is cached in the SkillFile MongoDB document; subsequent reads skip storage entirely. - Clicking a skill row now expands inline files (not just chevron). - Clicking a file navigates to `?file=<path>` and renders content in a new SkillFileViewer (markdown, code, images, binary placeholder). * chore: Remove react-window and its type definitions from package.json and package-lock.json - Deleted `react-window` and `@types/react-window` dependencies from both `package.json` and `package-lock.json` to streamline the project and reduce unnecessary bloat. * fix: Build errors — remove endpoints import, fix Uint8Array cast - Replace `import { endpoints }` (not public) with inline URL in SkillFileViewer - Remove `as Uint8Array` cast in stream chunk handling - Extend getSkillFileByPath return type with content/isBinary to decouple from data-schemas build artifact resolution * chore: Remove 8 unused i18next keys com_ui_create_skill_ai, com_ui_create_skill_manual, com_ui_delete_folder_confirm_var, com_ui_delete_skill, com_ui_delete_skill_confirm_var, com_ui_delete_var, com_ui_rename_var, com_ui_skill_files * fix: Add configMiddleware to skills router, handle SKILL.md in viewer - Add configMiddleware to skills router so req.config is populated when getLocalFileStream (or any strategy) reads file paths. - Handle SKILL.md in download handler — serves skill.body directly from the Skill document instead of looking for a SkillFile record. - Clicking SKILL.md in sidebar tree now opens the file viewer (matching Claude.ai behavior: file view vs default detail view). * ci: Run unit tests on PRs to any branch Remove the branches filter from both test workflows so contributor PRs targeting feature branches (not just main/dev) get CI coverage. Path filters are kept so tests only run when relevant files change. * fix: Update skills route tests for download handler changes - Mock configMiddleware (sets req.config for file storage access) - Mock getStrategyFunctions and getFileStrategy (storage strategy deps) - Replace 501 stub test with SKILL.md content test + 404 test * fix: Auto-expand files, frontmatter parsing, select-none, prefetch - Auto-expand file tree when navigating directly to a skill URL - Prefetch files for the active skill (eliminates first-expand lag) - Fix frontmatter parser to handle multi-line YAML list values (triggers field was missing because it uses list syntax) - SkillFileViewer now parses frontmatter for .md files — shows structured grid + rendered body (matching SkillDetail's display) with source/rendered toggle - Add select-none to all sidebar skill and file tree buttons * refactor: Derive expanded state from isActive instead of useEffect Replace useEffect sync with deterministic derivation: expanded = hasFiles && (isActive || !collapsed) Active skill is always open. collapsed is a manual toggle that only takes effect on non-active items. * fix: Remove empty space above body card — overlay view toggle Move the rendered/source toggle from a dedicated row (40px of empty space) to an absolute-positioned overlay in the card's top-right corner, matching Claude.ai's layout. * fix: Remove header bars from content editors — overlay action buttons Collapse the full-width header bars ("Skill Content", "Text") in SkillContentEditor, PromptTextCard, and PromptEditor. Action buttons (edit/save toggle, copy, variables) are now absolute-positioned in the card's top-right corner, reclaiming ~46px of vertical space. * fix: Spinner visibility in file viewer — use text-text-secondary * fix: Address review findings — security, correctness, code quality Codex P1: Use $unset instead of undefined to clear cached content and isBinary fields on file re-upload (Mongoose strips undefined). Codex P2: Match skill-file validation errors by error.code instead of error.message substring. F1: Zip bomb defense — track cumulative decompressed bytes (500 MB cap), check declared uncompressed size before buffering each entry. F2: Remove misleading "atomically" from import handler JSDoc. F3: Static import for isBinaryBuffer instead of dynamic import(). F4: Replace console.error with logger in upload handler. F6: Add multer error handler middleware to skills router. F7: Move React import to top of SkillDetail.tsx. F9: Fix variable shadowing (trimmed → item) in parseFrontmatter. F11: Replace JSON.parse(JSON.stringify()) with toJSON() for Mongoose document serialization. F12: Remove dead dynamic import('fs') fallback (memoryStorage always provides file.buffer). F13: Hoist MIME_MAP to module scope to avoid per-call allocation. F16: Share single multer.memoryStorage() instance. * fix: Follow-up review — close zip bomb gap, fix error handler F1: Add post-decompression cumulative byte check with break (the pre-decompression check relies on undocumented JSZip internals that may be absent; this closes the gap unconditionally). F2+F3: Multer error handler now forwards non-multer errors via next(err) instead of swallowing them. Also catches file filter rejections (plain Error, not MulterError) by message prefix. F4: Move isBinaryBuffer import to local imports section per CLAUDE.md import order rules. F5: Simplify dead toJSON branch — createSkill returns a POJO. * nit: Link filter error message to handler prefix check * feat: Accordion expansion + active file highlight in sidebar - Only one skill's file tree can be expanded at a time (accordion). Expansion state lifted from SkillListItem to SkillList. - Selected file gets bg-surface-active highlight in the tree. Skill row uses subtle style (no background) when a file is active, matching Claude.ai's pattern where the file — not the skill — carries the selection state. * style: Adjust margin for file tree in SkillListItem component - Reduced left margin from 10 to 5 for improved layout consistency in the file tree display. * fix: TS error on FileTreeNode, nested ternary, chevron collapse - Make style prop optional to match react-vtree's NodeComponentProps - Flatten nested ternary for skill row active styles - Skill row click expands (but doesn't collapse) files + navigates - Chevron click explicitly toggles collapse (matching Claude.ai where clicking the chevron is how you collapse files) * fix: Upload basePath, reject SKILL.md uploads, add skills permission route - Pass basePath: 'uploads' in per-file upload handler (was defaulting to 'images' path, inconsistent with the import flow). - Reject uploads targeting SKILL.md (reserved path — download handler special-cases it to return skill.body, making an uploaded file unreachable via the API). - Add skills entry to roles router permissionConfigs so PUT /api/roles/:roleName/skills actually reaches a handler instead of returning 404. * feat: Expand content area, move controls to header, reduce padding Default detail view: - Remove rounded-xl bordered card wrapper — content flows directly into the article, capitalizing on full screen width - Move eye/code toggle inline with the divider row - Reduce px-6/pb-6 to px-4/pb-4 File viewer: - Move eye/code toggle from card overlay to the header bar - Add copy-to-clipboard button for text files in the header bar - Remove rounded-xl bordered card wrapper for markdown content - Remove bordered pre wrapper for non-markdown text - Reduce px-6/py-4 to px-4/py-3 Both views maximize content space over decorative chrome. * fix: Stable header height, restore some padding - Fix layout shift in file viewer header: use fixed h-10 so the bar height stays constant whether the eye/code toggle renders (markdown) or not (plain text). - Bump content padding from px-4/py-3 back to px-5/py-4 in both views — the previous reduction was too aggressive. * fix: Grant rollback, path validation, error format, dead code cleanup F2: grantOwnership now rolls back (compensating delete) on failure, matching the create handler. Both markdown and zip import paths check the result and return 500 on grant failure. F4: Upload handler validates relativePath with regex + traversal check before calling downstream upsertSkillFile. F5: Document JSZip _data.uncompressedSize as best-effort; the post-decompression cumulative check is the real safety net. F10: Standardize all upload handler error responses to { error } (was { message }, inconsistent with handlers.ts). F13: Single-pass fileResults accumulation in import handler. F1-5: Remove dead uploadFileStubHandler (no route references it). Codex P2: Fix delete nav from /skills/new to /skills. F12: Use cn() in UploadSkillDialog instead of template literals. * perf: Stream-first binary detection + O(1) public skill check F1: Download handler now reads only the first 8 KB for binary detection. If binary, the stream is destroyed immediately without buffering the remaining file. Text files continue reading for caching. Eliminates buffering up to 10 MB per request for binary files under concurrent load. F7: Single-skill GET and PATCH now use hasPublicPermission (O(1) ACL lookup) instead of getPublicSkillIdSet (queries ALL public skill IDs). The list handler still uses the Set approach since it serializes multiple skills. serializeSkill/serializeSkillSummary now accept boolean | Set for flexibility. * fix: Update test to match { error } response format * fix: Critical stream truncation bug, grantedBy, error format NF-1 (CRITICAL): Rewrite binary detection to single for-await loop. Breaking out of for-await-of destroys the stream via iterator.return(), so the previous two-loop approach silently truncated text files > 8KB. Now: one loop collects chunks, checks binary after 8KB accumulated, and either destroys+returns (binary) or continues reading (text). NF-2: Add grantedBy to import handler's grantPermission call and interface (was missing, inconsistent with create handler). NF-3: Standardize all import handler error responses from { message } to { error }, matching handlers.ts convention. Update client's UploadSkillDialog to read response.data.error accordingly. * fix: Prefer specific validation message over generic error field * fix: YAML quote stripping, saveBuffer null guard, dot segment rejection - Strip surrounding YAML quotes from frontmatter values so name: "my-skill" parses as my-skill (not "my-skill" with quotes that fails the name validator). - Guard resolveSkillStorage against backends with saveBuffer: null (e.g. OpenAI/vector strategies) — throws a descriptive error caught by the handler's try/catch instead of a TypeError. - Tighten upload path validation to reject . segments (e.g. docs/./a.md) matching the model-layer validator, preventing storage writes for paths the DB will reject. * fix: Orphan cleanup, stream errors, malformed zip, cache latency F1: Upload handler now deletes the stored blob if the subsequent DB upsert fails, preventing orphaned files on disk/cloud. F2: Multer error handler returns { error } (was { message }). F3: Wrap JSZip.loadAsync in try/catch — malformed zip returns 400 instead of falling through to 500. F4: Raw download stream gets an error handler — logs the error and destroys the response if headers were already sent. F8: Strip leading hyphens from inferred skill name so filenames like _my-skill.zip don't produce -my-skill (invalid name pattern). F9: Fire-and-forget all updateSkillFileContent cache writes so the response is sent immediately. Cache failures are logged but don't block or fail the read. * fix: Import orphan cleanup + Content-Disposition sanitization Finding A: Add deleteFile dep to ImportSkillDeps. The per-file loop in handleZip now cleans up stored blobs when upsertSkillFile fails, closing the second half of the F1 orphan fix (upload handler was already fixed). Finding B: Sanitize filename in Content-Disposition header for raw downloads — strip quotes, backslashes, and newlines to prevent header injection from user-uploaded filenames. * security: Prevent stored XSS via raw file downloads Non-image files served via ?raw=true now use Content-Disposition: attachment (force download) instead of inline. An uploaded .html or .svg file served inline from the LibreChat origin could execute scripts with access to the user's session — this closes that vector. Images stay inline (needed for <img> rendering in SkillFileViewer). X-Content-Type-Options: nosniff added to prevent MIME sniffing. * security: Block SVG XSS — allowlist safe raster MIME types for inline SVG (image/svg+xml) passed the startsWith('image/') check and was served inline, but SVG is a scriptable format — embedded <script> tags execute in the LibreChat origin. Replace the prefix match with a Set of safe raster-only MIME types (png, jpeg, gif, webp, avif, bmp). SVGs and any future scriptable image/* subtypes now get Content-Disposition: attachment (forced download). * fix: Cap JSON text response at 1MB, consistent md name inference F3: Text files > 1MB now return { isBinary: false } with no content field, forcing the client to use ?raw=true for download. Prevents buffering 10MB files into heap for JSON serialization. Frontend shows a download fallback when content is absent. F4: handleMarkdown now infers skill name from filename (same as handleZip) when frontmatter has no name, instead of rejecting with 400. Consistent behavior across import paths. F1 (reviewer concern): upsertSkillFile is NOT affected — it uses { new: false } for insert-vs-replace detection but does a follow-up findOne (lines 855-859) to return the post-upsert document. * fix: deleteFile arg shape, raw URL base path, hoist SAFE_INLINE_MIMES Codex P2: deleteFile expects { filepath } object, not a raw string. Both upload handler cleanup and import handler cleanup now pass { filepath } to match the strategy contract (deleteLocalFile, deleteFileFromS3 all expect a file object). Codex P2: Raw download URL in SkillFileViewer now uses apiBaseUrl prefix so subpath deployments (/chat, etc.) resolve correctly. NIT: Hoist SAFE_INLINE_MIMES Set to factory scope — was re-allocated per raw download request inside the if block. * fix: Remove inert cache write for large text files, localize aria-label N2: The { isBinary: false } cache write for text files > 1MB had no effect — subsequent requests still fell through to stream read since neither isBinary nor content provided a fast-path short-circuit. Removed the pointless DB updateOne per request. N4: Replace hardcoded "Back to skill" aria-label with localize(). * refactor: Extract shared parseFrontmatter, widen deleteFile type N3: Extract parseFrontmatter into Skills/utils/frontmatter.ts — single implementation shared by SkillDetail and SkillFileViewer. Accepts optional skipKeys set so callers control which frontmatter fields are excluded (SkillDetail skips name/description since they're shown in the header; other .md files show all fields). N5: Widen ImportSkillDeps.deleteFile file param from { filepath } to { filepath; [key: string]: unknown } to signal extensibility if strategies start accessing additional file properties. * fix: Advance i past list items for skipped keys, DRY parseSkillMd Finding A: parseFrontmatter now consumes multi-line YAML list items before checking skipKeys — prevents list lines from leaking into subsequent key parsing as spurious fields. Finding B: parseSkillMd now delegates to the shared parseFrontmatter instead of re-implementing the same frontmatter scanning loop. Reduces client-side parseFrontmatter implementations from 3 to 1. * fix: Call apiBaseUrl(), delete storage blob on file removal - apiBaseUrl is a function, not a string — call it in the template literal so raw download URLs resolve correctly. - deleteFileHandler now looks up the file record before deleting, then fire-and-forget deletes the storage blob via the strategy's deleteFile. Previously only the DB record was removed, leaving orphaned blobs in local/S3/Firebase/Azure storage. * fix: Clean up storage blobs when deleting an entire skill deleteHandler now lists all files for the skill before calling deleteSkill, then fire-and-forget deletes each blob via the storage strategy. Previously only per-file deletion cleaned up blobs — deleting a whole skill left all associated files orphaned in local/S3/Firebase/Azure storage. * refactor: useImportSkillMutation hook, fix TSkill[] unsafe cast - Create useImportSkillMutation in mutations.ts + ImportSkillOptions type. UploadSkillDialog now uses the mutation hook instead of calling dataService.importSkill directly with manual useState loading management. Eliminates unmounted-component state update risk and aligns with the React Query mutation pattern used by every other mutation in the codebase. - SkillSelectDialog: replace as unknown as TSkill[] with proper TSkillSummary typing. SkillCard props updated to TSkillSummary. The dialog only uses summary-level fields (name, description, category, author) — the cast was hiding a type mismatch. * fix: Use saved source for import cleanup, delete old blob on replace Codex P2: Import cleanup now uses file.source (the backend the file was actually saved to) instead of re-resolving from config. In mixed strategy setups, the previous approach could target the wrong backend. Codex P2: When re-uploading a file to an existing relativePath, the old blob is now deleted after successful upsert. Previously only the DB record was replaced, leaving the old storage object orphaned. * fix: Register PUT /:roleName/skills route in roles router * fix: Re-read skill after zip file processing for fresh metadata The import response was built from the skill object created before the file loop, but each upsertSkillFile bumps version and fileCount. Clients caching the stale response would get 409 conflicts on first edit and see incorrect file counts. Now re-reads the skill via getSkillById after the loop so the response reflects the current version, fileCount, and updatedAt. * fix: Size-check SKILL.md before decompression, don't gate on fileCount P1: SKILL.md was decompressed before any size accounting. A crafted archive could expand SKILL.md past 10MB before validation ran. Now checks declared size pre-decompression and actual size post, both against MAX_SINGLE_FILE_BYTES. P2: File list query was gated on cached fileCount which can be stale after mutations. Now fetches files for the active skill regardless of fileCount. hasFiles derived from fetched data with fileCount as fallback, so newly uploaded files appear without hard refresh. * fix: Move files declaration before hasFiles to avoid TDZ error * security: Stream-decompress zip entries with enforced byte cap Replace zipEntry.async('nodebuffer') (buffers entire entry before checking limits) with zipEntry.nodeStream('nodebuffer') piped through a byte counter that destroys the stream when the per-file or cumulative limit is exceeded. Previously, when JSZip's _data.uncompressedSize was absent (the common case), a high-ratio entry could allocate hundreds of MB before the post-decompression check caught it. Now decompression is aborted mid-stream at the exact byte threshold — no entry can exceed its limit regardless of compression ratio. * refactor: Reorganize access check for prompts in useSideNavLinks hook Moved the prompts access check to a new position in the code to improve readability and maintainability. This change ensures that the prompts link is added to the navigation only if the user has the appropriate access, without altering the existing functionality. --------- Co-authored-by: Danny Avila <danny@librechat.ai> |

🔐 fix: Prefer WWW-Authenticate resource_metadata Hint for MCP OAuth (#12763)
* 📦 chore: Bump @modelcontextprotocol/sdk to v1.29.0 * ♻️ refactor: Extract WWW-Authenticate Probe Helper for MCP OAuth * 🔐 fix: Prefer WWW-Authenticate resource_metadata Hint for MCP OAuth Per RFC 9728 §5.1, the `resource_metadata=<url>` parameter in a 401 `WWW-Authenticate: Bearer` challenge is the authoritative protected-resource metadata source. Path-aware `.well-known` discovery was winning over the hint, so split deployments that serve valid-but-wrong metadata at the path-aware endpoint stranded OAuth at defunct authorization servers. Threads the hint through `discoverOAuthProtectedResourceMetadata` via `opts.resourceMetadataUrl` in both startup detection and the OAuth handler, matching the behavior of Claude Desktop, the MCP Inspector, OpenAI tooling, and Microsoft Copilot Studio. Fixes #12761. * 🧵 fix: Thread OAuth-Aware fetchFn Through Resource-Metadata Probe Without this, admin-configured `oauthHeaders` (e.g. a gateway API key that fronts the MCP endpoint) were stripped from the probe, causing the gateway to 401 for the wrong reason and masking the real `WWW-Authenticate` hint. The helper now accepts a FetchLike and defaults to global fetch, so the startup detection path is unchanged while the handler passes its OAuth- aware wrapper through. * 🧹 refactor: Address MCP OAuth Probe Review Findings - Thread `fetchFn` through `probeResourceMetadataHint` so admin-configured `oauthHeaders` reach the probe (a gateway API key that fronts the MCP endpoint would otherwise 401 us for the wrong reason and hide the real Bearer challenge). - Skip the redundant HEAD request in `checkAuthErrorFallback` when the probe already observed a 401/403; fall back to a fresh HEAD only when every probe attempt threw (transient network error). - Narrow the oauth barrel: drop `export * from './resourceHint'` so the helper stays an internal module. - Add `scope` extraction coverage (`Bearer scope="read write"`) and a 403-only observation path; isolate `MCP_OAUTH_ON_AUTH_ERROR=true` in a dedicated suite so precise-outcome tests aren't muddied by the safety net. * ✅ fix: Use Zod Schema in MCP Reconnection-Storm Test Tool MCP SDK 1.28 tightened `McpServer.tool()` to require Zod schemas instead of plain JSON-Schema objects. Swap the `{ message: { type: 'string' } }` shape for `z.string()` so the fixture server spins up under SDK 1.29. * 🛡️ fix: Harden MCP OAuth resource_metadata Hint Against SSRF The `resource_metadata` URL is echoed from an untrusted MCP server, so handing it straight to the SDK lets a malicious server redirect discovery at private IPs, the cloud metadata service, or any host the admin did not intend to reach. Caught by the Copilot review on #12763. - `handler.ts`: run the hint through the same `validateOAuthUrl` / `allowedDomains` gate that already guards the authorization-server URL; drop it and fall back to path-aware discovery on rejection. - `detectOAuth.ts`: no admin-scoped allowedDomains here, so apply a strict `isSSRFTarget` + DNS resolution check and silently discard any hint pointing at a private/loopback/metadata address. - Tests cover both the hostname-list and DNS-resolution rejection paths and assert the SDK falls back to path-aware discovery unharmed. * 🧪 test: Mock ~/auth in fallback Suite for Consistency Matches the main `detectOAuth.test.ts` mock so the SSRF guards added in the previous commit don't touch the real `~/auth` module at test time. * 🔍 fix: Scope OAuth Fallback to HEAD + Parse Multi-Scheme WWW-Authenticate Two codex findings on #12763: - **P1**: the merged `authChallenge` flag was letting POST-only 401/403 flip the `MCP_OAUTH_ON_AUTH_ERROR` fallback, misclassifying WAF/CSRF-hardened endpoints (HEAD 200 + POST 403) as OAuth-required. Rename to `headAuthChallenge` and derive it only from the HEAD probe, matching the legacy fallback's HEAD-only semantics. Add a regression test. - **P2**: the SDK's `extractWWWAuthenticateParams` only inspects the first scheme token, so multi-scheme headers like `Basic realm="api", Bearer resource_metadata="..."` silently dropped the authoritative Bearer hint. Fall back to a regex across the full header when the SDK returns nothing but Bearer is present. Add a regression test covering the multi-scheme case. * 🧽 refactor: Tighten MCP OAuth Probe Semantics Addresses the second external review pass plus codex P2: - Merge the two stacked JSDoc blocks on `probeResourceMetadataHint` into one with a proper `@returns` section. - Only short-circuit HEAD when it delivered the `resource_metadata` hint itself — a Bearer-without-params HEAD now lets POST run, since some servers surface their hint only on POST and we were missing it. - Drop the unused `scope` field from `ResourceHintProbeResult`; no caller read it, and YAGNI beats a reserved field. - Remove the redundant `OAUTH_ON_AUTH_ERROR` guard inside `checkAuthErrorFallback` — the only call site already gates on it. - Codex P2: signal "HEAD status unknown" via `null` when the HEAD probe threw and POST returned non-auth. Previously that combination leaked a `{headAuthChallenge: false}` result and silently skipped the fallback's retry HEAD, which could misclassify OAuth-required servers after a transient HEAD failure. Regression tests cover every path: Bearer-no-hint-on-HEAD + hint-on-POST, multi-scheme `Basic + Bearer` headers, HEAD-threw + POST-200 retry, and the WAF/CSRF-only POST 403 case. * 🪥 polish: Tighten Probe Null-Guard Ordering + Add Malformed-Hint Test Two NITs from the follow-up review: - Move `bearerChallenge` computation after the `!wwwAuth` guard so the variable is only derived when it can be meaningfully `true`. The early-return path is now a clean unconditional exit. - Add a regression test that asserts `Bearer resource_metadata="not-a-url"` yields `resourceMetadataUrl: undefined` without throwing, locking in the try/catch safety net in `extractHintFromHeader` and the SDK parser alike. |

🔍 fix: Anthropic Web Search Multi-Turn Issue and Attachment Results (#12651)
* 🔍 fix: Improve WebSearch Progress Handling Based on Attachment Results
- Adjusted progress handling in the WebSearch component to treat searches as complete if attachments contain results, addressing issues with server tool calls not receiving completion signals.
- Introduced `effectiveProgress` to reflect the actual state of progress based on the presence of results, enhancing the accuracy of cancellation and completion states.
- Updated related logic to ensure proper handling of search completion and finalization states based on the new progress calculations.
* fix: only override progress when not streaming
During streaming (isSubmitting=true), use actual progress so the
searching/processing/reading states display correctly. Only override
to 1 after streaming completes to prevent the cancelled check from
hiding the component.
* chore: Update @librechat/agents and mathjs dependencies to latest versions
* chore: Upgrade mathjs dependency to version 15.2.0 across package-lock and package.json files

⚗️ feat: Agent Context Compaction/Summarization (#12287)
* chore: imports/types
Add summarization config and package-level summarize handler contracts
Register summarize handlers across server controller paths
Port cursor dual-read/dual-write summary support and UI status handling
Selectively merge cursor branch files for BaseClient summary content
block detection (last-summary-wins), dual-write persistence, summary
block unit tests, and on_summarize_status SSE event handling with
started/completed/failed branches.
Co-authored-by: Cursor <cursoragent@cursor.com>
refactor: type safety
feat: add localization for summarization status messages
refactor: optimize summary block detection in BaseClient
Updated the logic for identifying existing summary content blocks to use a reverse loop for improved efficiency. Added a new test case to ensure the last summary content block is updated correctly when multiple summary blocks exist.
chore: add runName to chainOptions in AgentClient
refactor: streamline summarization configuration and handler integration
Removed the deprecated summarizeNotConfigured function and replaced it with a more flexible createSummarizeFn. Updated the summarization handler setup across various controllers to utilize the new function, enhancing error handling and configuration resolution. Improved overall code clarity and maintainability by consolidating summarization logic.
feat(summarization): add staged chunk-and-merge fallback
feat(usage): track summarization usage separately from messages
feat(summarization): resolve prompt from config in runtime
fix(endpoints): use @librechat/api provider config loader
refactor(agents): import getProviderConfig from @librechat/api
chore: code order
feat(app-config): auto-enable summarization when configured
feat: summarization config
refactor(summarization): streamline persist summary handling and enhance configuration validation
Removed the deprecated createDeferredPersistSummary function and integrated a new createPersistSummary function for MongoDB persistence. Updated summarization handlers across various controllers to utilize the new persistence method. Enhanced validation for summarization configuration to ensure provider, model, and prompt are properly set, improving error handling and overall robustness.
refactor(summarization): update event handling and remove legacy summarize handlers
Replaced the deprecated summarization handlers with new event-driven handlers for summarization start and completion across multiple controllers. This change enhances the clarity of the summarization process and improves the integration of summarization events in the application. Additionally, removed unused summarization functions and streamlined the configuration loading process.
refactor(summarization): standardize event names in handlers
Updated event names in the summarization handlers to use constants from GraphEvents for consistency and clarity. This change improves maintainability and reduces the risk of errors related to string literals in event handling.
feat(summarization): enhance usage tracking for summarization events
Added logic to track summarization usage in multiple controllers by checking the current node type. If the node indicates a summarization task, the usage type is set accordingly. This change improves the granularity of usage data collected during summarization processes.
feat(summarization): integrate SummarizationConfig into AppSummarizationConfig type
Enhanced the AppSummarizationConfig type by extending it with the SummarizationConfig type from librechat-data-provider. This change improves type safety and consistency in the summarization configuration structure.
test: add end-to-end tests for summarization functionality
Introduced a comprehensive suite of end-to-end tests for the summarization feature, covering the full LibreChat pipeline from message creation to summarization. This includes a new setup file for environment configuration and a Jest configuration specifically for E2E tests. The tests utilize real API keys and ensure proper integration with the summarization process, enhancing overall test coverage and reliability.
refactor(summarization): include initial summary in formatAgentMessages output
Updated the formatAgentMessages function to return an initial summary alongside messages and index token count map. This change is reflected in multiple controllers and the corresponding tests, enhancing the summarization process by providing additional context for each agent's response.
refactor: move hydrateMissingIndexTokenCounts to tokenMap utility
Extracted the hydrateMissingIndexTokenCounts function from the AgentClient and related tests into a new tokenMap utility file. This change improves code organization and reusability, allowing for better management of token counting logic across the application.
refactor(summarization): standardize step event handling and improve summary rendering
Refactored the step event handling in the useStepHandler and related components to utilize constants for event names, enhancing consistency and maintainability. Additionally, improved the rendering logic in the Summary component to conditionally display the summary text based on its availability, providing a better user experience during the summarization process.
feat(summarization): introduce baseContextTokens and reserveTokensRatio for improved context management
Added baseContextTokens to the InitializedAgent type to calculate the context budget based on agentMaxContextNum and maxOutputTokensNum. Implemented reserveTokensRatio in the createRun function to allow configurable context token management. Updated related tests to validate these changes and ensure proper functionality.
feat(summarization): add minReserveTokens, context pruning, and overflow recovery configurations
Introduced new configuration options for summarization, including minReserveTokens, context pruning settings, and overflow recovery parameters. Updated the createRun function to accommodate these new options and added a comprehensive test suite to validate their functionality and integration within the summarization process.
feat(summarization): add updatePrompt and reserveTokensRatio to summarization configuration
Introduced an updatePrompt field for updating existing summaries with new messages, enhancing the flexibility of the summarization process. Additionally, added reserveTokensRatio to the configuration schema, allowing for improved management of token allocation during summarization. Updated related tests to validate these new features.
feat(logging): add on_agent_log event handler for structured logging
Implemented an on_agent_log event handler in both the agents' callbacks and responses to facilitate structured logging of agent activities. This enhancement allows for better tracking and debugging of agent interactions by logging messages with associated metadata. Updated the summarization process to ensure proper handling of log events.
fix: remove duplicate IBalanceUpdate interface declaration
perf(usage): single-pass partition of collectedUsage
Replace two Array.filter() passes with a single for-of loop that
partitions message vs. summarization usages in one iteration.
fix(BaseClient): shallow-copy message content before mutating and preserve string content
Avoid mutating the original message.content array in-place when
appending a summary block. Also convert string content to a text
content part instead of silently discarding it.
fix(ui): fix Part.tsx indentation and useStepHandler summarize-complete handling
- Fix SUMMARY else-if branch indentation in Part.tsx to match chain level
- Guard ON_SUMMARIZE_COMPLETE with didFinalize flag to avoid unnecessary
re-renders when no summarizing parts exist
- Protect against undefined completeData.summary instead of unsafe spread
fix(agents): use strict enabled check for summarization handlers
Change summarizationConfig?.enabled !== false to === true so handlers
are not registered when summarizationConfig is undefined.
chore: fix initializeClient JSDoc and move DEFAULT_RESERVE_RATIO to module scope
refactor(Summary): align collapse/expand behavior with Reasoning component
- Single render path instead of separate streaming vs completed branches
- Use useMessageContext for isSubmitting/isLatestMessage awareness so
the "Summarizing..." label only shows during active streaming
- Default to collapsed (matching Reasoning), user toggles to expand
- Add proper aria attributes (aria-hidden, role, aria-controls, contentId)
- Hide copy button while actively streaming
feat(summarization): default to self-summarize using agent's own provider/model
When no summarization config is provided (neither in librechat.yaml nor
on the agent), automatically enable summarization using the agent's own
provider and model. The agents package already provides default prompts,
so no prompt configuration is needed.
Also removes the dead resolveSummarizationLLMConfig in summarize.ts
(and its spec) — run.ts buildAgentContext is the single source of truth
for summarization config resolution. Removes the duplicate
RuntimeSummarizationConfig local type in favor of the canonical
SummarizationConfig from data-provider.
chore: schema and type cleanup for summarization
- Add trigger field to summarizationAgentOverrideSchema so per-agent
trigger overrides in librechat.yaml are not silently stripped by Zod
- Remove unused SummarizationStatus type from runs.ts
- Make AppSummarizationConfig.enabled non-optional to reflect the
invariant that loadSummarizationConfig always sets it
refactor(responses): extract duplicated on_agent_log handler
refactor(run): use agents package types for summarization config
Import SummarizationConfig, ContextPruningConfig, and
OverflowRecoveryConfig from @librechat/agents and use them to
type-check the translation layer in buildAgentContext. This ensures
the config object passed to the agent graph matches what it expects.
- Use `satisfies AgentSummarizationConfig` on the config object
- Cast contextPruningConfig and overflowRecoveryConfig to agents types
- Properly narrow trigger fields from DeepPartial to required shape
feat(config): add maxToolResultChars to base endpoint schema
Add maxToolResultChars to baseEndpointSchema so it can be configured
on any endpoint in librechat.yaml. Resolved during agent initialization
using getProviderConfig's endpoint resolution: custom endpoint config
takes precedence, then the provider-specific endpoint config, then the
shared `all` config.
Passed through to the agents package ToolNode, which uses it to cap
tool result length before it enters the context window. When not
configured, the agents package computes a sensible default from
maxContextTokens.
fix(summarization): forward agent model_parameters in self-summarize default
When no explicit summarization config exists, the self-summarize
default now forwards the agent's model_parameters as the
summarization parameters. This ensures provider-specific settings
(e.g. Bedrock region, credentials, endpoint host) are available
when the agents package constructs the summarization LLM.
fix(agents): register summarization handlers by default
Change the enabled gate from === true to !== false so handlers
register when no explicit summarization config exists. This aligns
with the self-summarize default where summarization is always on
unless explicitly disabled via enabled: false.
refactor(summarization): let agents package inherit clientOptions for self-summarize
Remove model_parameters forwarding from the self-summarize default.
The agents package now reuses the agent's own clientOptions when the
summarization provider matches the agent's provider, inheriting all
provider-specific settings (region, credentials, proxy, etc.)
automatically.
refactor(summarization): use MessageContentComplex[] for summary content
Unify summary content to always use MessageContentComplex[] arrays,
matching the pattern used by on_message_delta. No more string | array
unions — content is always an array of typed blocks ({ type: 'text',
text: '...' } for text, { type: 'reasoning_content', ... } for
reasoning).
Agents package:
- SummaryContentBlock.content: MessageContentComplex[] (was string)
- tokenCount now optional (not sent on deltas)
- Removed reasoning field — reasoning is now a content block type
- streamAndCollect normalizes all chunks to content block arrays
- Delta events pass content blocks directly
LibreChat:
- SummaryContentPart.content: Agents.MessageContentComplex[]
- Updated Part.tsx, Summary.tsx, useStepHandler.ts, BaseClient.js
- Summary.tsx derives display text from content blocks via useMemo
- Aggregator uses simple array spread
refactor(summarization): enhance summary handling and text extraction
- Updated BaseClient.js to improve summary text extraction, accommodating both legacy and new content formats.
- Modified summarization logic to ensure consistent handling of summary content across different message formats.
- Adjusted test cases in summarization.e2e.spec.js to utilize the new summary text extraction method.
- Refined SSE useStepHandler to initialize summary content as an array.
- Updated configuration schema by removing unused minReserveTokens field.
- Cleaned up SummaryContentPart type by removing rangeHash property.
These changes streamline the summarization process and ensure compatibility with various content structures.

- Removed direct checks for summarization nodes in ModelEndHandler and replaced them with a dedicated markSummarizationUsage function for better readability and maintainability.
- Updated OpenAIChatCompletionController and responses handlers to utilize the new markSummarizationUsage function for setting usage types.
- Enhanced logging functionality by ensuring the logger correctly handles different log levels.
- Introduced a new useCopyToClipboard hook in the Summary component to encapsulate clipboard copy logic, improving code reusability and clarity.
These changes improve the overall structure and efficiency of the summarization handling and logging processes.
refactor(summarization): update summary content block documentation
- Removed outdated comment regarding the last summary content block in BaseClient.js.
- Added a new comment to clarify the purpose of the findSummaryContentBlock method, ensuring consistency in documentation.
These changes enhance code clarity and maintainability by providing accurate descriptions of the summarization logic.
refactor(summarization): update summary content structure in tests
- Modified the summarization content structure in e2e tests to use an array format for text, aligning with recent changes in summary handling.
- Updated test descriptions to clarify the behavior of context token calculations, ensuring consistency and clarity in the tests.
These changes enhance the accuracy and maintainability of the summarization tests by reflecting the updated content structure.
refactor(summarization): remove legacy E2E test setup and configuration
- Deleted the e2e-setup.js and jest.e2e.config.js files, which contained legacy configurations for E2E tests using real API keys.
- Introduced a new summarization.e2e.ts file that implements comprehensive E2E backend integration tests for the summarization process, utilizing real AI providers and tracking summaries throughout the run.
These changes streamline the testing framework by consolidating E2E tests into a single, more robust file while removing outdated configurations.
refactor(summarization): enhance E2E tests and error handling
- Added a cleanup step to force exit after all tests to manage Redis connections.
- Updated the summarization model to 'claude-haiku-4-5-20251001' for consistency across tests.
- Improved error handling in the processStream function to capture and return processing errors.
- Enhanced logging for cross-run tests and tight context scenarios to provide better insights into test execution.
These changes improve the reliability and clarity of the E2E tests for the summarization process.
refactor(summarization): enhance test coverage for maxContextTokens behavior
- Updated run-summarization.test.ts to include a new test case ensuring that maxContextTokens does not exceed user-defined limits, even when calculated ratios suggest otherwise.
- Modified summarization.e2e.ts to replace legacy UsageMetadata type with a more appropriate type for collectedUsage, improving type safety and clarity in the test setup.
These changes improve the robustness of the summarization tests by validating context token constraints and refining type definitions.
feat(summarization): add comprehensive E2E tests for summarization process
- Introduced a new summarization.e2e.test.ts file that implements extensive end-to-end integration tests for the summarization pipeline, covering the full flow from LibreChat to agents.
- The tests utilize real AI providers and include functionality to track summaries during and between runs.
- Added necessary cleanup steps to manage Redis connections post-tests and ensure proper exit.
These changes enhance the testing framework by providing robust coverage for the summarization process, ensuring reliability and performance under real-world conditions.
fix(service): import logger from winston configuration
- Removed the import statement for logger from '@librechat/data-schemas' and replaced it with an import from '~/config/winston'.
- This change ensures that the logger is correctly sourced from the updated configuration, improving consistency in logging practices across the application.
refactor(summary): simplify Summary component and enhance token display
- Removed the unused `meta` prop from the `SummaryButton` component to streamline its interface.
- Updated the token display logic to use a localized string for better internationalization support.
- Adjusted the rendering of the `meta` information to improve its visibility within the `Summary` component.
These changes enhance the clarity and usability of the Summary component while ensuring better localization practices.
feat(summarization): add maxInputTokens configuration for summarization
- Introduced a new `maxInputTokens` property in the summarization configuration schema to control the amount of conversation context sent to the summarizer, with a default value of 10000.
- Updated the `createRun` function to utilize the new `maxInputTokens` setting, allowing for more flexible summarization based on agent context.
These changes enhance the summarization capabilities by providing better control over input token limits, improving the overall summarization process.
refactor(summarization): simplify maxInputTokens logic in createRun function
- Updated the logic for the `maxInputTokens` property in the `createRun` function to directly use the agent's base context tokens when the resolved summarization configuration does not specify a value.
- This change streamlines the configuration process and enhances clarity in how input token limits are determined for summarization.
These modifications improve the maintainability of the summarization configuration by reducing complexity in the token calculation logic.
feat(summary): enhance Summary component to display meta information
- Updated the SummaryContent component to accept an optional `meta` prop, allowing for additional contextual information to be displayed above the main content.
- Adjusted the rendering logic in the Summary component to utilize the new `meta` prop, improving the visibility of supplementary details.
These changes enhance the user experience by providing more context within the Summary component, making it clearer and more informative.
refactor(summarization): standardize reserveRatio configuration in summarization logic
- Replaced instances of `reserveTokensRatio` with `reserveRatio` in the `createRun` function and related tests to unify the terminology across the codebase.
- Updated the summarization configuration schema to reflect this change, ensuring consistency in how the reserve ratio is defined and utilized.
- Removed the per-agent override logic for summarization configuration, simplifying the overall structure and enhancing clarity.
These modifications improve the maintainability and readability of the summarization logic by standardizing the configuration parameters.
* fix: circular dependency of `~/models`
* chore: update logging scope in agent log handlers
Changed log scope from `[agentus:${data.scope}]` to `[agents:${data.scope}]` in both the callbacks and responses controllers to ensure consistent logging format across the application.
* feat: calibration ratio
* refactor(tests): update summarizationConfig tests to reflect changes in enabled property
Modified tests to check for the new `summarizationEnabled` property instead of the deprecated `enabled` field in the summarization configuration. This change ensures that the tests accurately validate the current configuration structure and behavior of the agents.
* feat(tests): add markSummarizationUsage mock for improved test coverage
Introduced a mock for the markSummarizationUsage function in the responses unit tests to enhance the testing of summarization usage tracking. This addition supports better validation of summarization-related functionalities and ensures comprehensive test coverage for the agents' response handling.
* refactor(tests): simplify event handler setup in createResponse tests
Removed redundant mock implementations for event handlers in the createResponse unit tests, streamlining the setup process. This change enhances test clarity and maintainability while ensuring that the tests continue to validate the correct behavior of usage tracking during on_chat_model_end events.
* refactor(agents): move calibration ratio capture to finally block
Reorganized the logic for capturing the calibration ratio in the AgentClient class to ensure it is executed in the finally block. This change guarantees that the ratio is captured even if the run is aborted, enhancing the reliability of the response message persistence. Removed redundant code and improved clarity in the handling of context metadata.
* refactor(agents): streamline bulk write logic in recordCollectedUsage function
Removed redundant bulk write operations and consolidated document handling in the recordCollectedUsage function. The logic now combines all documents into a single bulk write operation, improving efficiency and reducing error handling complexity. Updated logging to provide consistent error messages for bulk write failures.
* refactor(agents): enhance summarization configuration resolution in createRun function
Streamlined the summarization configuration logic by introducing a base configuration and allowing for overrides from agent-specific settings. This change improves clarity and maintainability, ensuring that the summarization configuration is consistently applied while retaining flexibility for customization. Updated the handling of summarization parameters to ensure proper integration with the agent's model and provider settings.
* refactor(agents): remove unused tokenCountMap and streamline calibration ratio handling
Eliminated the unused tokenCountMap variable from the AgentClient class to enhance code clarity. Additionally, streamlined the logic for capturing the calibration ratio by using optional chaining and a fallback value, ensuring that context metadata is consistently defined. This change improves maintainability and reduces potential confusion in the codebase.
* refactor(agents): extract agent log handler for improved clarity and reusability
Refactored the agent log handling logic by extracting it into a dedicated function, `agentLogHandler`, enhancing code clarity and reusability across different modules. Updated the event handlers in both the OpenAI and responses controllers to utilize the new handler, ensuring consistent logging behavior throughout the application.
* test: add summarization event tests for useStepHandler
Implemented a series of tests for the summarization events in the useStepHandler hook. The tests cover scenarios for ON_SUMMARIZE_START, ON_SUMMARIZE_DELTA, and ON_SUMMARIZE_COMPLETE events, ensuring proper handling of summarization logic, including message accumulation and finalization. This addition enhances test coverage and validates the correct behavior of the summarization process within the application.
* refactor(config): update summarizationTriggerSchema to use enum for type validation
Changed the type of the `type` field in the summarizationTriggerSchema from a string to an enum with a single value 'token_count'. This modification enhances type safety and ensures that only valid types are accepted in the configuration, improving overall clarity and maintainability of the schema.
* test(usage): add bulk write tests for message and summarization usage
Implemented tests for the bulk write functionality in the recordCollectedUsage function, covering scenarios for combined message and summarization usage, summarization-only usage, and message-only usage. These tests ensure correct document handling and token rollup calculations, enhancing test coverage and validating the behavior of the usage tracking logic.
* refactor(Chat): enhance clipboard copy functionality and type definitions in Summary component
Updated the Summary component to improve the clipboard copy functionality by handling clipboard permission errors. Refactored type definitions for SummaryProps to use a more specific type, enhancing type safety. Adjusted the SummaryButton and FloatingSummaryBar components to accept isCopied and onCopy props, promoting better separation of concerns and reusability.
* chore(translations): remove unused "Expand Summary" key from English translations
Deleted the "Expand Summary" key from the English translation file to streamline the localization resources and improve clarity in the user interface. This change helps maintain an organized and efficient translation structure.
* refactor: adjust token counting for Claude model to account for API discrepancies
Implemented a correction factor for token counting when using the Claude model, addressing discrepancies between Anthropic's API and local tokenizer results. This change ensures accurate token counts by applying a scaling factor, improving the reliability of token-related functionalities.
* refactor(agents): implement token count adjustment for Claude model messages
Added a method to adjust token counts for messages processed by the Claude model, applying a correction factor to align with API expectations. This enhancement improves the accuracy of token counting, ensuring reliable functionality when interacting with the Claude model.
* refactor(agents): token counting for media content in messages
Introduced a new method to estimate token costs for image and document blocks in messages, improving the accuracy of token counting. This enhancement ensures that media content is properly accounted for, particularly for the Claude model, by integrating additional token estimation logic for various content types. Updated the token counting function to utilize this new method, enhancing overall reliability and functionality.
* chore: fix missing import
* fix(agents): clamp baseContextTokens and document reserve ratio change
Prevent negative baseContextTokens when maxOutputTokens exceeds the
context window (misconfigured models). Document the 10%→5% default
reserve ratio reduction introduced alongside summarization.
* fix(agents): include media tokens in hydrated token counts
Add estimateMediaTokensForMessage to createTokenCounter so the hydration
path (used by hydrateMissingIndexTokenCounts) matches the precomputed
path in AgentClient.getTokenCountForMessage. Without this, messages
containing images or documents were systematically undercounted during
hydration, risking context window overflow.
Add 34 unit tests covering all block-type branches of
estimateMediaTokensForMessage.
* fix(agents): include summarization output tokens in usage return value
The returned output_tokens from recordCollectedUsage now reflects all
billed LLM calls (message + summarization). Previously, summarization
completions were billed but excluded from the returned metadata, causing
a discrepancy between what users were charged and what the response
message reported.
* fix(tests): replace process.exit with proper Redis cleanup in e2e test
The summarization E2E test used process.exit(0) to work around a Redis
connection opened at import time, which killed the Jest runner and
bypassed teardown. Use ioredisClient.quit() and keyvRedisClient.disconnect()
for graceful cleanup instead.
* fix(tests): update getConvo imports in OpenAI and response tests
Refactor test files to import getConvo from the main models module instead of the Conversation submodule. This change ensures consistency across tests and simplifies the import structure, enhancing maintainability.
* fix(clients): improve summary text validation in BaseClient
Refactor the summary extraction logic to ensure that only non-empty summary texts are considered valid. This change enhances the robustness of the message processing by utilizing a dedicated method for summary text retrieval, improving overall reliability.
* fix(config): replace z.any() with explicit union in summarization schema
Model parameters (temperature, top_p, etc.) are constrained to
primitive types rather than the policy-violating z.any().
* refactor(agents): deduplicate CLAUDE_TOKEN_CORRECTION constant
Export from the TS source in packages/api and import in the JS client,
eliminating the static class property that could drift out of sync.
* refactor(agents): eliminate duplicate selfProvider in buildAgentContext
selfProvider and provider were derived from the same expression with
different type casts. Consolidated to a single provider variable.
* refactor(agents): extract shared SSE handlers and restrict log levels
- buildSummarizationHandlers() factory replaces triplicated handler
blocks across responses.js and openai.js
- agentLogHandlerObj exported from callbacks.js for consistent reuse
- agentLogHandler restricted to an allowlist of safe log levels
(debug, info, warn, error) instead of accepting arbitrary strings
* fix(SSE): batch summarize deltas, add exhaustiveness check, conditional error announcement
- ON_SUMMARIZE_DELTA coalesces rapid-fire renders via requestAnimationFrame
instead of calling setMessages per chunk
- Exhaustive never-check on TStepEvent catches unhandled variants at
compile time when new StepEvents are added
- ON_SUMMARIZE_COMPLETE error announcement only fires when a summary
part was actually present and removed
* feat(agents): persist instruction overhead in contextMeta and seed across runs
Extend contextMeta with instructionOverhead and toolCount so the
provider-observed instruction overhead is persisted on the response message
and seeded into the pruner on subsequent runs. This enables the pruner to
use a calibrated budget from the first call instead of waiting for a
provider observation, preventing the ratio collapse caused by local
tokenizer overestimating tool schema tokens.
The seeded overhead is only used when encoding and tool count match
between runs, ensuring stale values from different configurations
are discarded.
* test(agents): enhance OpenAI test mocks for summarization handlers
Updated the OpenAI test suite to include additional mock implementations for summarization handlers, including buildSummarizationHandlers, markSummarizationUsage, and agentLogHandlerObj. This improves test coverage and ensures consistent behavior during testing.
* fix(agents): address review findings for summarization v2
Cancel rAF on unmount to prevent stale Recoil writes from dead
component context. Clear orphaned summarizing:true parts when
ON_SUMMARIZE_COMPLETE arrives without a summary payload. Add null
guard and safe spread to agentLogHandler. Handle Anthropic-format
base64 image/* documents in estimateMediaTokensForMessage. Use
role="region" for expandable summary content. Add .describe() to
contextMeta Zod fields. Extract duplicate usage loop into helper.
* refactor: simplify contextMeta to calibrationRatio + encoding only
Remove instructionOverhead and toolCount from cross-run persistence —
instruction tokens change too frequently between runs (prompt edits,
tool changes) for a persisted seed to be reliable. The intra-run
calibration in the pruner still self-corrects via provider observations.
contextMeta now stores only the tokenizer-bias ratio and encoding,
which are stable across instruction changes.
* test(SSE): enhance useStepHandler tests for ON_SUMMARIZE_COMPLETE behavior
Updated the test for ON_SUMMARIZE_COMPLETE to clarify that it finalizes the existing part with summarizing set to false when the summary is undefined. Added assertions to verify the correct behavior of message updates and the state of summary parts.
* refactor(BaseClient): remove handleContextStrategy and truncateToolCallOutputs functions
Eliminated the handleContextStrategy method from BaseClient to streamline message handling. Also removed the truncateToolCallOutputs function from the prompts module, simplifying the codebase and improving maintainability.
* refactor: add AGENT_DEBUG_LOGGING option and refactor token count handling in BaseClient
Introduced AGENT_DEBUG_LOGGING to .env.example for enhanced debugging capabilities. Refactored token count handling in BaseClient by removing the handleTokenCountMap method and simplifying token count updates. Updated AgentClient to log detailed token count recalculations and adjustments, improving traceability during message processing.
* chore: update dependencies in package-lock.json and package.json files
Bumped versions of several dependencies, including @librechat/agents to ^3.1.62 and various AWS SDK packages to their latest versions. This ensures compatibility and incorporates the latest features and fixes.
* chore: imports order
* refactor: extract summarization config resolution from buildAgentContext
* refactor: rename and simplify summarization configuration shaping function
* refactor: replace AgentClient token counting methods with single-pass pure utility
Extract getTokenCount() and getTokenCountForMessage() from AgentClient
into countFormattedMessageTokens(), a pure function in packages/api that
handles text, tool_call, image, and document content types in one loop.
- Decompose estimateMediaTokensForMessage into block-level helpers
(estimateImageDataTokens, estimateImageBlockTokens, estimateDocumentBlockTokens)
shared by both estimateMediaTokensForMessage and the new single-pass function
- Remove redundant per-call getEncoding() resolution (closure captures once)
- Remove deprecated gpt-3.5-turbo-0301 model branching
- Drop this.getTokenCount guard from BaseClient.sendMessage
* refactor: streamline token counting in createTokenCounter function
Simplified the createTokenCounter function by removing the media token estimation and directly calculating the token count. This change enhances clarity and performance by consolidating the token counting logic into a single pass, while maintaining compatibility with Claude's token correction.
* refactor: simplify summarization configuration types
Removed the AppSummarizationConfig type and directly used SummarizationConfig in the AppConfig interface. This change streamlines the type definitions and enhances consistency across the codebase.
* chore: import order
* fix: summarization event handling in useStepHandler
- Cancel pending summarizeDeltaRaf in clearStepMaps to prevent stale
frames firing after map reset or component unmount
- Move announcePolite('summarize_completed') inside the didFinalize
guard so screen readers only announce when finalization actually occurs
- Remove dead cleanup closure returned from stepHandler useCallback body
that was never invoked by any caller
* fix: estimate tokens for non-PDF/non-image base64 document blocks
Previously estimateDocumentBlockTokens returned 0 for unrecognized MIME
types (e.g. text/plain, application/json), silently underestimating
context budget. Fall back to character-based heuristic or countTokens.
* refactor: return cloned usage from markSummarizationUsage
Avoid mutating LangChain's internal usage_metadata object by returning
a shallow clone with the usage_type tag. Update all call sites in
callbacks, openai, and responses controllers to use the returned value.
* refactor: consolidate debug logging loops in buildMessages
Merge the two sequential O(n) debug-logging passes over orderedMessages
into a single pass inside the map callback where all data is available.
* refactor: narrow SummaryContentPart.content type
Replace broad Agents.MessageContentComplex[] with the specific
Array<{ type: ContentTypes.TEXT; text: string }> that all producers
and consumers already use, improving compile-time safety.
* refactor: use single output array in recordCollectedUsage
Have processUsageGroup append to a shared array instead of returning
separate arrays that are spread into a third, reducing allocations.
* refactor: use for...in in hydrateMissingIndexTokenCounts
Replace Object.entries with for...in to avoid allocating an
intermediate tuple array during token map hydration.

💣 fix: Harden against falsified ZIP metadata in ODT parsing (#12320)
* security: replace JSZip metadata guard with yauzl streaming decompression The ODT decompressed-size guard was checking JSZip's private _data.uncompressedSize fields, which are populated from the ZIP central directory — attacker-controlled metadata. A crafted ODT with falsified uncompressedSize values bypassed the 50MB cap entirely, allowing content.xml decompression to exhaust Node.js heap memory (DoS). Replace JSZip with yauzl for ODT extraction. The new extractOdtContentXml function uses yauzl's streaming API: it lazily iterates ZIP entries, opens a decompression stream for content.xml, and counts real bytes as they arrive from the inflate stream. The stream is destroyed the moment the byte count crosses ODT_MAX_DECOMPRESSED_SIZE, aborting the inflate before the full payload is materialised in memory. - Remove jszip from direct dependencies (still transitive via mammoth) - Add yauzl + @types/yauzl - Update zip-bomb test to verify streaming abort with DEFLATE payload * fix: close file descriptor leaks and declare jszip test dependency - Use a shared `finish()` helper in extractOdtContentXml that calls zipfile.close() on every exit path (success, size cap, missing entry, openReadStream errors, zipfile errors). Without this, any error path leaked one OS file descriptor permanently — uploading many malformed ODTs could exhaust the process FD limit (a distinct DoS vector). - Add jszip to devDependencies so the zip-bomb test has an explicit dependency rather than relying on mammoth's transitive jszip. - Update JSDoc to document that all exit paths close the zipfile. * fix: move yauzl from dependencies to peerDependencies Matches the established pattern for runtime parser libraries in packages/api: mammoth, pdfjs-dist, and xlsx are all peerDependencies (provided by the consuming /api workspace) with devDependencies for testing. yauzl was incorrectly placed in dependencies. * fix: add yauzl to /api dependencies to satisfy peer dep packages/api declares yauzl as a peerDependency; /api is the consuming workspace that must provide it at runtime, matching the pattern used for mammoth, pdfjs-dist, and xlsx. |
