* 🔧 chore: Update dependencies in package-lock.json and package.json
Bump `form-data` to version 4.0.6 and update `hasown` and `mime-types` dependencies in package-lock.json. Add an `overrides` section in package.json to ensure compatibility with the new `form-data` version.
* 📦 chore: Bump `@librechat/agents` to v3.2.42
* fix(agents): use `path` for read/write/edit/create file tools
Pairs with @librechat/agents renaming the read_file/write_file/edit_file tool
parameter from `file_path` to `path` (models — esp. Kimi K2 — emit `path` far
more reliably, and it matches grep/glob/list_directory which already use `path`).
- tools.ts: LibreChat's own code/skill file-tool schemas use `path`
(the skill read_file tool inherits the SDK definition, which is already renamed)
- handlers.ts: read `args.path` for the model-facing tool arg + error messages
- the internal host `readSandboxFile`/`writeSandboxFile` contract is unchanged
- tests updated
Requires @librechat/agents with the param rename (danny-avila/agents#250). All
agents unit suites green (175).
* chore: update @librechat/agents to v3.2.41 and bump related dependencies in package-lock.json and package.json files
* fix(api): Refactor header merging in MCPConnection to use Object.assign for clarity
* test(e2e): mock emits `path` for create/edit file-authoring tools
The mock LLM still sent `file_path` for the create_file/edit_file calls, which the
renamed handlers no longer read -> the skill-file-authoring e2e failed with
'Expected skill to be persisted'. Switch the fixture to `path` to match the tools.
(The internal readSandboxFile/writeSandboxFile contract stays on `file_path`, so
api/server/services/Files/Code/process.js and its spec are unchanged.)

* 🪙 feat: Context-usage projection — data-provider + client wiring
Consumer side of the SDK-aligned context projection (agents
`projectAgentContextUsage`). Adds the `/api/endpoints/context-projection`
data-provider plumbing (endpoint, service, query key, `TContextProjectionRequest`)
and a `useContextProjectionQuery` gated to fire only when no fresh snapshot
covers the viewed branch.
Wires `useTokenUsage` precedence to: live snapshot → fresh persisted snapshot
(window matches the resolved one) → server projection → per-message estimate.
A model/window switch marks the baked snapshot stale (its `maxContextTokens`
no longer matches) and falls to the projection — closing the gauge's
window-switch (G1) and snapshot-less-branch (G2) gaps. Snapshot and projection
share the render-relevant fields, so they render uniformly.
Backend endpoint + agents version bump land in follow-up commits. Includes the
design spec (CONTEXT_PROJECTION_SPEC.md).
* 🪙 feat: Context-projection backend endpoint
POST /api/endpoints/context-projection → resolveContextProjection (packages/api):
reconstructs the viewed branch (parent-chain walk from messageId), resolves the
agent config (instructions/provider/model/maxContextTokens), reuses LibreChat's
stored per-message tokenCounts as the index map (no re-tokenizing), and calls
the agents SDK projectAgentContextUsage — no model call. Thin controller injects
db.getMessages/db.getAgent; route mirrors /token-config.
First cut targets message-windowing accuracy; tool-schema tokens are deferred to
a follow-up that reuses the full initializeAgent path.
* 🩹 fix: Codex review on context projection (G1 guard, IDOR, recount, summary)
- Guard `currentActive` against a stale window: a model/window switch on the
current branch left the live snapshot outranking the projection (G1 didn't
fire). Now defers to the projection unless streaming or the window matches.
- Scope branch lookups to the authenticated user (`getMessages` filter +
injected `userId`) — was loading any conversation by id (IDOR).
- Recount messages with no stored `tokenCount` via the tokenizer instead of
charging 0, so snapshot-less/imported histories don't under-report.
- Fall back (null) for already-summarized branches rather than projecting from
the full raw parent chain (the next call would send summary + tail); the
client's summary-baseline-aware estimate handles them until a follow-up
replays the summary boundary.
* 🩹 fix: Codex round 2 — drop agent load, summary marker, edit-invalidation
- Stop loading agent/model-spec config server-side (closes the agent-access
IDOR and the spec-prompt special-casing). Provider/model/window now come from
the client-resolved request (`limits.endpoint`/model — the agent's real
provider, not the `agents` endpoint, so the tokenizer is right). Agent/spec/
promptPrefix instructions are uniformly deferred to the full-fidelity follow-up.
- Detect summarized branches via the live path's `metadata.summaryUsedTokens`
marker (was the wrong `summaryTokenCount` field) and fall back to the
summary-aware estimate.
- Invalidate the projection query on in-place message edits via a branch
content `revision` in the cache key (the tail id is unchanged on edit).
Deferred (valid, not a regression): same-window endpoint/model switch keeps a
window-matched snapshot — needs endpoint/model persisted on the snapshot, which
lands with the fidelity follow-up. Smoke-tested: fits / prunes / summarized→null
/ no-window→null.
* 🛡️ fix: make context projection strictly additive (no-regression)
Revert the G1 window-match guard on the live/branch snapshot. When no explicit
maxContextTokens is set (the common default), the SDK's snapshot window is
reserve-derived (~0.9·(modelContext − maxOutputTokens)) while useTokenLimits
resolves the raw model context — so `snapshot.maxContextTokens === resolvedMax`
is false for the SAME model, and the guard would wrongly drop a valid
current-branch snapshot to projection/estimate post-stream (a regression in the
default case, per initialize.ts:1240-1243).
The projection now activates ONLY for snapshot-less branches (G2): the
precedence is live snapshot → persisted branch snapshot → projection → estimate,
where the first two are byte-for-byte the prior behavior and the projection just
slots ahead of the estimate. Window/model-switch (G1) detection needs the
snapshot to carry its model/window and defers to the fidelity follow-up.
* 🩹 fix: surface projections as estimates, not authoritative snapshots
A first-cut projection carries the SDK's windowing but omits instruction/tool
overhead, so rendering it as `isEstimate: false` showed a confident under-count
for snapshot-less branches. Mark projection-sourced views `isEstimate: true` +
`snapshotActive: false` (and drop the snapshot field) so they present as a
better estimate than sumBranch — improved used/window number, estimate framing,
no misleading granular breakdown with ~0 tools. Real snapshots stay
authoritative. (Codex round 3, projection.ts:139.)

Tool batches already execute in parallel here, but results were only

(agents SDK > 3.2.33) as it settles, letting the graph emit that
call's completion immediately. resolve remains the authoritative batch
outcome; the callback is optional-chained, so this is a no-op until
the SDK release lands and remains backward compatible after.

Keep the Google Gen AI SDK aligned with the latest 2.x release. Updates the
declared range in both backend manifests (api, packages/api) and regenerates
the lockfile to resolve @google/genai to 2.8.0.
No application code changes: the sole consumer
(api/app/clients/tools/structured/GeminiImageGen.js) uses the stable
`GoogleGenAI` constructor and `models.generateContent` API, and the upstream
changelog records no breaking changes to those between 2.0 and 2.8.
Closes#13551
The tsdown migration (#13595) externalizes all third-party imports
(Rollup inlined them), so several modules the api source imports must be
present at runtime. Six were not, causing production (`npm ci --omit=dev`)
to crash on boot with `Cannot find module 'get-stream'` (then the next).
Fixed following the package's existing convention — packages/api declares
runtime libs as `peerDependencies`, and the `/api` app provides them as
real `dependencies` (how express/mongoose/sharp already resolve):
- `api/package.json` (the prod app, the provider): add the 3 that were
missing — `get-stream`, `jszip`, `mongodb`. (`dedent`/`lodash`/`nanoid`
were already provided by /api.)
- `packages/api/package.json`: add all 6 to `peerDependencies` (the
contract) and to `devDependencies` (workspace build/tests), matching
the existing `mammoth`/`pdfjs-dist`/`sanitize-html` dev+peer pattern.
`jszip`/`mongodb` move out of dev-only (were pruned in production).
Pinned to CJS-compatible majors (get-stream@6, nanoid@3). Verified the
built bundle has zero undeclared externals and the 3 newly-provided deps
are production (non-dev) in the lockfile, so they survive `--omit=dev`.
* ⚡️ refactor: Migrate @librechat/api build to tsdown
Replace Rollup with tsdown (rolldown + oxc isolated-declarations) for the
@librechat/api package build, mirroring the merged data-schemas migration.
- Add tsdown.config.mjs (cjs output, oxc dts, externalize all bare deps,
bundle first-party `~/` + relative imports)
- Annotate exports for isolatedDeclarations (codefix-driven). Collapse the
tokens.ts model->token maps to Record<string, Record<string, number>> and
switch validation.ts's runtime `files` field from z.any() to z.unknown()
so no explicit `any` is introduced
- Repoint package.json main/types/exports to tsdown's .cjs/.d.cts output
- Add src/telemetry.ts entry shim so the two index.ts entries don't collide
in oxc's flat dts output (stable dist/telemetry.{cjs,d.cts})
- Delete rollup.config.js
Build time ~36s -> ~0.5s. No runtime behavior change: 5712 unit tests pass,
both entries load via require(), legacy /api consumes them unchanged.
* 👷 ci: Hash packages/api/tsdown.config.mjs in build-api cache keys
The build-api cache keys hashed `packages/api/server-rollup.config.js`,
which never existed (api used `rollup.config.js`, now removed) — a copy-paste
artifact from the data-provider key that matched no file. Replace it with the
new `packages/api/tsdown.config.mjs` so edits to the build config (entry,
format, externals) bust the api build cache, matching the data-schemas key.
Bumps typescript 5.3.3 -> 5.9.3 across all workspaces. typescript-eslint must move 8.24.0 -> 8.60.1 too: 8.24's typescript peer was capped at <5.8.0; 8.60.1 widens it to <6.1.0.
Two errors surfaced by the newer compiler are fixed:
- api/src/rum/proxy.ts: TS 5.9 made `Buffer` generic (`Buffer<ArrayBufferLike>`), which no longer structurally matches `BodyInit`; cast the fetch body (Node's fetch accepts a Buffer at runtime).
- client usePresetIndexOptions.ts: drop a dead `|| {}` on an object spread (always truthy — flagged by the new TS2872 check).
All four package typecheck jobs + the client app typecheck pass under 5.9.3; builds (tsdown + rollup) and the rum proxy tests are unaffected.

* 🧱 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 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.
