Danny Avila	fe30e3db32	🪫 fix: Back Off Failed Retention Deletes (#15608) ... * 🧹 fix: Stop Undeletable Files Starving the Retention Sweep `getExpiredFiles` returns the oldest `expiredAt` first, capped at `limit`, and `processDeleteRequest` leaves the record in place when storage deletion fails. Nothing records the failure, so the same files come back at the head of the next batch an hour later, forever: no backoff, no cap, and — once `limit` of them cannot be deleted — no file that expires afterwards is ever swept again. On the deployment behind #15511 that is ~29k stranded objects permanently occupying a 100-slot queue, which is why fixing the Code Interpreter side alone (LibreChat-AI/code-interpreter#85) would not have resumed deletion there. Failures are now recorded on the file. `deletionRetryAt` holds it back with a backoff doubling from one sweep interval to a day, and `deletionAttempts` retires it from the query entirely once it reaches `FILE_RETENTION_SWEEP_MAX_ATTEMPTS` (10, so roughly five days of retries). Both fields are absent on existing records and absence means "never attempted", so nothing already in the collection changes eligibility. The record itself is kept rather than deleted — the reference is what an operator needs to reconcile a bucket the sweep could not clear, and dropping it would restore the silence that made this leak invisible. Raising `FILE_RETENTION_SWEEP_MAX_ATTEMPTS` re-admits everything previously given up on, which is the supported way to resume once the storage-side failure is fixed; the give-up is logged with that instruction. The counter is incremented server-side with `$inc` so concurrent sweeps on separate nodes cannot overwrite each other's progress toward the cap, and a failure to record a failure is logged and skipped rather than aborting the rest of the batch. * 🧭 fix: Delete Code Environment Files Through the Route That Exists `deleteCodeEnvFile` tried `/sessions/:sid/objects/:fid` before falling back to `/files/:sid/:fid`. Both have been there since #13424, but only the second is mounted by any released codeapi — the first gained DELETE in LibreChat-AI/code-interpreter#85 — so every deletion paid a guaranteed 404 and a wasted round trip, and #15511 read that 404 as the whole bug. Call `/files/:sid/:fid` directly. It is the safe direction to collapse toward: codeapi has mounted it since its first release, so this works against older deployments as well as post-#85 ones, whereas keeping the other path would not. Collapsing the loop tightens two behaviours that only existed to serve it. A 405 now surfaces instead of being swallowed on the way to a second attempt; there is no second route to try, and a service that refuses the method should say so. A 404 is still treated as "already gone" — that is the only thing it can now mean — but it is logged rather than passed over in silence, because a 404 caused by a misconfigured base URL looks identical and this branch drops the file's metadata record either way. * 🔒 fix: Settle sweep retry state from the write, not the read Two findings from the review of 0e52924. - `recordFailure` derived the attempt number by adding one to the count the batch had queried. Two nodes sweeping the same file read the same value, so both believed themselves to be the same attempt: each `$inc` landed, the stored count crossed `FILE_RETENTION_SWEEP_MAX_ATTEMPTS`, and neither caller ever saw the threshold. The file drops out of the query — the starvation guard still holds — but the give-up is never reported, and that log line is the operator's only notice, and carries the instruction for resuming. Return the count from the increment itself so every caller gets a distinct attempt number and exactly one observes the cap. The same staleness shortened the backoff, so `deferExpiredFile` now writes with `$max`: a deferral can only move later, and a node that computed a shorter delay cannot pull the file forward past one another node already committed. - The backoff doubled from a hard-coded hour while claiming to start from one sweep interval. At the default they coincide; away from it the schedule stops meaning anything — on a six-hour sweep the first three attempts all land on consecutive passes, and on a five-minute one the first retry skips twelve. Derive the base from `FILE_RETENTION_SWEEP_INTERVAL_MS`, floored at a minute so a pathologically short interval cannot spend the whole give-up budget on a transient outage. * 🧯 fix: Keep the give-up notice and the retry budget honest Four findings from the review of ee1bac5. - The give-up was reported after the deferral write, inside the same catch. Once the increment lands the counter is durable, so `getExpiredFiles` already excludes the file; a deferral that then failed left only the generic recording error and dropped the one line naming the file and saying how to resume. Report it as soon as the increment returns, and let the deferral fail on its own. - Retry deadlines were measured from `Date.now()` after the deletion I/O, but `startExpiredFileSweep` arms its interval before the sweep runs. A one-interval delay therefore expired just *after* the next scheduled pass, which skipped the file and pushed its first retry out by a whole extra interval — and the same drift applied to every delay that is an exact multiple. Anchor deadlines to the sweep's start instead. - The threshold used `>=`, so once two nodes pushed a file past the cap every one of them past it logged the give-up: one error per replica per exhausted file rather than one actionable notice. Only the attempt that lands exactly on the cap reports it. - Retry state outlived the content it described. `processCodeOutput` reuses a record for a repeated `(filename, conversationId)` — new bytes, new storage key, and a fresh `expiredAt` from `getRetentionExpiry` — while `createFile` and `updateFile` set only supplied fields. A record carried to the cap by its previous content stayed excluded from the sweep forever, stranding the new object exactly as this PR set out to prevent; a partially failed one started the new object's budget already spent. Both write paths now clear the fields: the budget belongs to the storage a record currently points at. The retry-state fixtures in `file.spec.ts` were seeded through `createFile`, which now clears them, so they drive the real methods the sweep uses. * 🎯 fix: Clear the retry budget only when a retention lifecycle starts Both findings from the review of 8d26f9b, and both are consequences of that commit's reset rather than of the original change. - The reset was unconditional on every `createFile`/`updateFile`, on the reasoning that those paths write content. Two of them do not. `prepareImages{Local,Azure,Firebase}` call `updateFile({ file_id })` with nothing but the id — a TTL touch — every time an existing image is encoded for another chat, and the deferred preview uses the same method to transition `status`. Either handed a stranded record a fresh set of attempts and another give-up notice, on repeat, defeating the cap for the files most likely to be stranded. Gate it on the write actually setting `expiredAt`. The budget belongs to a retention lifecycle: that is the write which starts a new one, it is what `processCodeOutput` supplies when it repurposes a record, and a record with no retention deadline is never swept, so the fields are inert there anyway. - Both retry writes bumped `updatedAt`. `processCodeOutput` falls back to `updatedAt` as the writer-order stamp for records that predate `metadata.sourceDispatchedAt`, so a failed sweep landing mid-harvest read as a newer content writer and the harvest dropped its attachment. Mark them `timestamps: false`, for the reason `claimCodeFile` already does: bookkeeping is not a content write. * 🅿️ refactor: Park exhausted files instead of excluding them Three review rounds in a row found defects in how the give-up cap interacts with record reuse, each in the fix for the last. That is a design error, not a bug list: a permanent exclusion has to be bound precisely to the content lifecycle it was recorded against, and File records outlive their content. `processCodeOutput` repurposes a row for a repeated `(filename, conversationId)`, `createFile`/`updateFile` set only supplied fields, and `getRetentionExpiry` returns `{}` on a lookup failure so the row inherits its old deadline — three separate ways for bookkeeping to survive into a lifecycle it does not describe, each needing its own guard, and the two retry writes needing to be lifecycle-conditional on top. Remove the category instead. `deletionRetryAt` becomes the sweep's only hold, and reaching `FILE_RETENTION_SWEEP_MAX_ATTEMPTS` parks the file for a month rather than excluding it. The bound on the batch is the same — a stranded file costs one slot a month instead of one an hour — but a deadline that outlives its content can only delay the next object, never lose it, so nothing outside the sweep has to reason about this state at all. That deletes more than it adds: - `createFile` and `updateFile` go back to their original form. No reset, so no question of which writes install content, and `prepareImages*` and the deferred preview stop mattering here. - `getExpiredFiles` loses `maxAttempts` and its `$and`; eligibility is one `$or` on the deadline. - The interleaving race between the increment and the deferral degrades from a stranded object to a delayed one. Working through a large backlog is throughput-bound either way: every attempt costs a slot in the bounded batch, so N stranded files need N × `FILE_RETENTION_SWEEP_MAX_ATTEMPTS` passes to settle. Lower that limit when recovering a deployment that has accumulated many.	2026-09-04 15:38:17 -04:00

Danny Avila	93c4ef4ba8	🧱 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	2026-05-08 12:29:43 -04:00
Danny Avila	4a5fc701d2	📂 fix: Preserve Nested Skill Paths in Code-Env Uploads (#12877) ... * fix(code): preserve code env upload filepaths * chore: Reorder import statements in crud.js	2026-04-29 08:07:46 -04:00
Danny Avila	35bf04b26c	🧰 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.

Danny Avila	39f5f83a8a	🔌 fix: Isolate Code-Server HTTP Agents to Prevent Socket Pool Contamination (#12311) ... * 🔧 fix: Isolate HTTP agents for code-server axios requests Prevents socket hang up after 5s on Node 19+ when code executor has file attachments. follow-redirects (axios dep) leaks `socket.destroy` as a timeout listener on TCP sockets; with Node 19+ defaulting to keepAlive: true, tainted sockets re-enter the global pool and destroy active node-fetch requests in CodeExecutor after the idle timeout. Uses dedicated http/https agents with keepAlive: false for all axios calls targeting CODE_BASEURL in crud.js and process.js. Closes #12298 * ♻️ refactor: Extract code-server HTTP agents to shared module - Move duplicated agent construction from crud.js and process.js into a shared agents.js module to eliminate DRY violation - Switch process.js from raw `require('axios')` to `createAxiosInstance()` for proxy configuration parity with crud.js - Fix import ordering in process.js (agent constants no longer split imports) - Add 120s timeout to uploadCodeEnvFile (was the only code-server call without a timeout) * ✅ test: Add regression tests for code-server socket isolation - Add crud.spec.js covering getCodeOutputDownloadStream and uploadCodeEnvFile (agent options, timeout, URL, error handling) - Add socket pool isolation tests to process.spec.js asserting keepAlive:false agents are forwarded to axios - Update process.spec.js mocks for createAxiosInstance() migration * ♻️ refactor: Move code-server agents to packages/api Relocate agents.js from api/server/services/Files/Code/ to packages/api/src/utils/code.ts per workspace conventions. Consumers now import codeServerHttpAgent/codeServerHttpsAgent from @librechat/api.	2026-03-19 16:16:57 -04:00
