Danny Avila	f7bc50ae5b	📦 chore: bump @librechat/agents to v3.3.4 (#14482)	2026-07-28 08:36:18 -04:00
Danny Avila	531fecc82b	🍃 chore: Bump Mongoose to 8.24.1 to Patch Prototype Pollution (#14461) ... Closes GHSA-664h-wqgq-64gw (CVSS 6.5, CWE-1321), a prototype pollution in update casting via a __proto__-prefixed dotted path. Affected range is >=8.0.0 <8.24.1, so 8.23.1 was flagged by npm audit.	2026-07-27 12:40:14 -04:00
Danny Avila	a53936d273	🧭 test: Cover Agent Handoffs End to End (#14428) ... * test: cover agent handoffs end to end * style: sort handoff imports * fix: normalize missing agent handoff edges * chore: update package dependencies and versions in package-lock.json and package.json * chore: bump agents SDK	2026-07-27 08:47:15 -04:00
Danny Avila	ca6ffb33fd	📦 chore: Update @librechat/agents to v3.2.68 (#14380)	2026-07-21 21:40:54 -04:00
Danny Avila	cbaa2fe2e3	⚡ feat: Add Gemini 3.6 Flash and Gemini 3.5 Flash-Lite Support (#14369) ... * ⚡ feat: Add Gemini 3.6 Flash and Gemini 3.5 Flash-Lite Support Adds first-class support for Google's Gemini 3.6 Flash (`gemini-3.6-flash`) and Gemini 3.5 Flash-Lite (`gemini-3.5-flash-lite`) for both the Gemini API (AI Studio) and Google Cloud/Vertex integrations. - Context window (1M) in googleModels; API + cache pricing in tx.ts. - Model dropdown (config.ts) and GOOGLE_MODELS examples for both integrations. - Generalize the Gemini 3.5 Flash overrides into a flash-family handler that strips deprecated temperature/topP/topK and applies each model's default thinking level (3.6 Flash: medium, 3.5 Flash-Lite: minimal), with longest-prefix resolution so flash-lite does not collide with flash. Ref: https://ai.google.dev/gemini-api/docs/latest-model#api-changes-and-parameter-updates * 🩹 fix: Strip unsupported penalty params for Gemini Flash family Gemini 3.6 Flash, 3.5 Flash-Lite, and 3.5 Flash reject presencePenalty/ frequencyPenalty with HTTP 400 ("Penalty is not enabled for this model", verified live). These pass through llmConfig via knownGoogleParams, so add them to the flash-family strip list alongside the deprecated sampling params. * 🩹 fix: Strip Flash-blocked params on custom Google endpoint path For custom OpenAI-compatible endpoints with defaultParamsEndpoint=google, getOpenAIConfig strips Flash-blocked params via getGoogleConfig but then transformToOpenAIConfig re-applies raw addParams, undoing the strip. Filter addParams through stripGeminiFlashBlockedParams before the transform so the deprecated sampling / rejected penalty params cannot reach the provider. * 🔧 chore: Update sharp package to version 0.35.3 in package-lock.json, api/package.json, and packages/api/package.json * 🔧 chore: Update dependencies in package-lock.json to latest versions for @google/genai (2.13.0), @hono/node-server (1.19.14), fast-uri (3.1.4), hono (4.12.31), and svgo (2.8.3) * 🔧 chore: Update dependencies in package.json and package-lock.json for @librechat/agents (3.2.67), @opentelemetry/sdk-node (0.221.0), and add new dependencies for @opentelemetry/propagator-jaeger (2.10.0) and protobufjs (7.6.5). Update monaco-editor version in client package.json to 0.56.0. * 🔧 chore: Upgrade turbo package to version 2.10.5 in package.json and package-lock.json, and update schema reference in turbo.json * 🩹 fix: Resolve CI breakage from bundled dependency bumps Not related to the Gemini models — both are fallout from the dep bumps on this branch: - monaco-editor 0.56 changed IEditorHoverOptions.enabled from boolean to 'on' | 'off' | 'onKeyboardModifier'; update ArtifactCodeEditor to match (mirrors the sibling occurrencesHighlight/matchBrackets pattern). - sharp 0.35.3 fails resize+encode on a degenerate 1x1 PNG (vipspng: libpng read error); the provider-file e2e fixture was 1x1, so use a 16x16 PNG. Normal images are unaffected (verified 64x64 resize/encode/jpeg all OK). * 📝 docs: Correct e2e image-fixture comment (bad IDAT CRC, not a sharp bug) Root cause was the old 1x1 fixture's corrupt IDAT CRC (verified: IHDR/IEND CRC OK, IDAT CRC BAD), which sharp 0.35.3's stricter libpng correctly rejects. Not a dimension/resize edge case and not a sharp bug; comment now reflects that.	2026-07-21 21:14:11 -04:00

Danny Avila	9bb351ad9c	🧭 feat: Mid-Run Steering and Queued Messages for Agent Runs (#14220) ... * 🧭 feat: Mid-Run Steering and Queued Messages for Agent Runs Steering: submit a message while a run is generating; the server queues it in the job store (cross-instance) and a run-scoped PostToolBatch hook injects it into graph state at the next tool-batch boundary, records an inline 'steer' content part on the response (replayed as a user message on later turns), and streams on_steer_applied to the client. Queuing: messages composed during a run auto-send as normal follow-up turns after clean completion (one per final event, FIFO); user aborts leave them as chips unless armed by interrupt-and-send. Requires hook injectedMessages support in @librechat/agents (danny-avila/agents#299); hard-gated via a capability probe so older SDKs 501 the steer route instead of draining and dropping messages. * 🧵 fix: Harden Steering Against Finalization Races and Route Guard Gaps Addresses local Codex review findings on the steering feature: - Close-and-drain the steer queue atomically at finalization (final event, abort) so a steer POST racing teardown is rejected instead of 202-ACKed and then silently cleared; the closed flag lives on the job hash and is reset when a replacement job reuses the stream id. - Clear inherited steer queues on createJob — a job replacement must not drain the replaced run's messages. - Keep steers queued across a HITL pause instead of draining them into ephemeral client state: resumeState re-seeds chips on reload and the resumed run injects them at its first tool boundary (steers key TTL now extends to the approval window; on_steers_pending event removed). - Queue the NO_ACTIVE_RUN steer fallback while the final SSE is still settling — a direct send would be dropped by ask()'s in-flight guard. - Reconcile the 202 ACK against on_steer_applied events that beat it over the SSE, so a chip can't be re-minted after its removal event passed. - Allow the per-send Steer override when the default action is queue. - Apply the configured message rate limiters and the PII filter to POST /chat/steer — a steer is model-bound user text. * ✅ ci: Assert Steering Capability Probe Against the Installed SDK CI installs the published @librechat/agents pin (pre-injectedMessages), where isSteeringSupported() is legitimately false — the probe test now asserts it mirrors the installed SDK's capability flag instead of hardcoding the capability-bearing build's value. Verified against both the published 3.2.61 dist and the agents#299 build. * 🛟 fix: Preserve Steer Text Across Run-End, Error, and Abort Races Codex round 2 (4 P2s): - Applied-steer-id set survives run end (capped at 100) and converted ids join it, so a 202 ACK that lands after final/abort drops its chip instead of re-minting a stranded pending one. - Failed runs no longer strand acknowledged chips: both error paths convert local pending chips to queued follow-ups (chip text is client-local), and the server closes the steer queue before emitting the error so a racing steer POST gets 404 fallback instead of a 202 whose payload dies with the job. - sendQueuedNow keys on steer availability, not the default action — send-now on a queued chip is an explicit override for queue-preferring users. - Stop path consumes pendingSteers from the abort HTTP response as a fallback for the SSE final event it may close before processing; conversion is deduped so double delivery is a no-op (shared useSteerConvert hook). * 📎 feat: Carry Attachments Through During-Run Queued Messages Steering stays text-only (SDK injection, inline STEER part, and replay are all text), so a during-run submit with media now queues the whole message as one unit instead of silently stranding the files: - QueuedMessage gains `files`; composer attachments are consumed into the queued item at queue time (steerFromComposer / queueFromComposer / interruptAndSend), fixing the latent hazard where lingering composer files glued onto whatever `ask` vacuumed up next. - Enter-steer with attachments degrades to queue with an explanatory toast; the per-send menu routes through the same composer-aware wrappers. - The drain and sendQueuedNow pass the item's files as `overrideFiles`; media items never steer (send as a normal turn when idle, re-front otherwise). ask() no longer clears composer state for caller-supplied overrideFiles — only regenerate keeps that behavior. - During-run submits hold while uploads are in flight, mirroring the send button's filesLoading gate; queued chips show a paperclip count. * 🎛️ feat: Rework During-Run Chips into Action Rows Full-width rows above the composer (reference-UI parity): each queued message shows a primary Steer/Send-now action, delete, and a "…" menu with Edit message (restores text + attachments into the composer) and a Turn on queueing/steering toggle that flips the Enter default. Steer rows share the layout with status text; failed steers keep retry / edit / queue-convert. The per-send menu gains the same default toggle. Queued file refs now retain filename + bytes so edit-restore rebuilds real composer entries (draft-recovery shape). * 🖇️ feat: Steer With Attachments (Multimodal Mid-Run Injection) Steering now carries media end-to-end instead of degrading to queue: - The steer POST accepts sanitized attachment refs (cap 10; only file_id is trusted — the drain re-fetches owner-scoped and re-derives everything else). SteerQueueItem/TPendingSteer/SteerContentPart carry `files` refs; encoded data is never persisted or queued. - New api/server/services/Files/steering.js decouples attachment building from the request path: encodeSteerContent reuses the exact per-turn pipeline (addFileContextToMessage + processAttachments' single-pass categorize/encode, SDK formatMessage assembly, prependFileContext for extracted text) with zero new encoding code. buildSteerMedia feeds the drain hook's new buildMedia seam (any failure degrades that steer to text-only — words always land); stampSteerPartMedia re-encodes past steer parts per turn with ONE batched owner-scoped fetch and stamps a transient `media` array, replaced immutably so it can never leak into a save. Replay honors resendFiles like regular message media. - The SDK's formatAgentMessages (the formatter agents actually use) gained the steer replay branch on the PR branch; the local formatMessages.js branch now mirrors the media preference. - Client: steerFromComposer consumes composer files into the POST, chips/seeding/conversions carry files everywhere (retry, queue convert, abort/error recovery), queued media items steer for real, and SteerBubble renders the steered attachments inline. * 🧵 fix: Harden Steer Recovery Races and Drain Isolation Codex round 3 (7 fixes): - A 202 ACK landing after the run ended converts straight to a queued follow-up (server queue is gone; no event will ever resolve a pending chip for a finished run). Covers stream errors with in-flight POSTs. - A Stop that lands pre-completion can arrive as a final with unfinished:true and no aborted flag — runEnd now treats it as aborted so queued messages are not auto-sent against the user's Stop. - Leftover-steer conversion merges chronologically by createdAt instead of appending, preserving the order the user composed. - Auto-drained queued messages pass explicit (possibly empty) overrideFiles/overrideQuotes/overrideManualSkills: a drain can no longer vacuum up files, quotes, or skill picks staged in the composer for the user's NEXT message (ask() treats overrideFiles != null as authoritative). - Failed-steer Retry and resume-on-load chip restoration keep the steer's attachments. - The job-replacement guard moved INSIDE the store's atomic drain/close-and-drain (Lua createdAt compare; in-memory equivalent): a stale run's hook or finalization can neither consume, close, nor steal a replacement job's steer queue, and the drain hook drops its separate check-then-drain round trip. * 🧰 refactor: Typed Steer Controller, Single-Query Media Pass, Round-4 Fixes Codex round 4 + efficiency tightening in one pass: - Moved the steer guard ladder (validation, file sanitization via a shared toSteerFileRef picker, ownership/tenant checks, status-guarded enqueue) into packages/api as handleSteerRequest; api/steer.js is now a thin wrapper. Ladder covered against the REAL in-memory job manager in request.spec.ts; the api spec pins only the wrapper contract. - Folded the steer replay stamp into the turn's ONE historical-files query: collectHistoricalFileRefs also gathers steer-part refs, the owner-scoped doc map rides client state, and stampSteerPartMedia consumes it (no second round trip) while encoding parts in parallel. - Stamped steer media now counts against the run budget (existing multimodal counter over the non-text parts, folded into indexTokenCountMap/promptTokens after the stamp). - Steer route runs the PII filter BEFORE moderateText, matching chat.js so blocked sensitive text never reaches the external moderation API. - Interrupt & send survives the abort-response-beats-SSE-final race: stopGenerating writes the run-end signal itself when the one-shot interrupt flag is armed and no signal landed (double-fire safe). - Resume reconciles chips against the server's still-queued list even when EMPTY, clearing chips for steers applied while disconnected. - The local formatter's steer flush preserves non-text assistant parts (array-content AIMessage) instead of folding to text. * 🔒 fix: Replay-Aware Capability Gate and Round-5 Race Closures - isSteeringSupported now requires BOTH halves of the SDK contract: injection (HOOK_INJECTED_MESSAGES_CAPABLE) AND replay (ContentTypes.STEER, shipped in the same SDK commit as the formatAgentMessages steer branch). An SDK that can inject but not replay 501s the steer route — no release window can create steer parts that would leak into provider-facing assistant content. - The local formatter mirrors the SDK's anchor reset: a post-steer tool_call mints a fresh AIMessage instead of attaching to the pre-steer anchor (invalid provider ordering). - Queued-chip send-now and the NO_ACTIVE_RUN fallback pass explicit (possibly empty) overrideFiles so an idle send can't vacuum composer files staged for a different draft. - Redis createJob deletes the stale steer list BEFORE the replacement hash is written as running — a steer 202-accepted against the new job can never be wiped by the reset. - Resumed-turn finalization mirrors the normal path's terminal drain: createdAt-guarded close-and-drain, leftovers ride the resumed final event as pendingSteers instead of being cleared by completeJob. - buildSteerMedia restores composer order over the $in result so multi-attachment steers reach the model in the order the user saw. * ⚛️ fix: Atomic Job Replacement and Boundary-Clean Steering Module Codex round 6 (5 fixed, 1 standing deferral): - createJob resets the steer queue and writes the job hash in ONE same-slot Lua script (JOB_CREATE_LUA): a steer POST can no longer interleave between them on cluster, so a steer accepted against one run can never be drained into another. Redis-validated. - The steering media pipeline moved to packages/api (agents/steering/media.ts) with injected getFiles and a structural client interface — /api keeps zero steering logic; specs ported to the DI seam. - handleSteerRequest checks the job BEFORE the capability gate: a steer racing completion on an unsupported SDK gets 404 (send-now) instead of a 501 queue with no run-end signal left to drain it. - useQueueDrain binds to the active conversation: navigating away between the final SSE and the drain effect leaves the signal unconsumed instead of submitting A's follow-up into B; the drain fires on return. - abortJob closes and drains the steer queue BEFORE the content snapshot, so a drain-hook apply that lands pre-drain is captured inline rather than lost between the snapshot and the terminal drain. * 🚦 fix: Parked Run-End Signals, Interrupt Priority, Settled-Run Fallbacks Codex round 7 (5 fixes): - Run-end signals for a non-active conversation are PARKED per conversation instead of squatting the shared index slot: a later run finishing on the same pane can no longer overwrite them, and the parked drain fires when the user returns. - "Interrupt & send" front-inserts carry a priority flag that outranks createdAt when abort leftovers merge back chronologically — the urgent redirect drains first, not the oldest steer. - STEER_UNSUPPORTED/RUN_PAUSED/QUEUE_FULL rejections landing after the run settled mirror the NO_ACTIVE_RUN fallback and send immediately (queueing would strand the text with no run-end signal left); on the pinned SDK this is the common Enter-near-run-end path. - A failed abort (e.g. 404 when the run completed first) still signals the interrupt drain, so the queued interrupt message can't strand and the armed flag can't leak onto a later run. - Steered-image fallback alt text is localized (com_ui_attached_image). * 📌 chore: Adopt Published @librechat/agents Types Post-Bump dev's pin bump to ^3.2.62 (the release carrying injection + steer replay) landed via merge; the steering runtime now uses the SDK's real InjectedMessage/hook-output types instead of the local structural mirrors that bridged the pre-publish window. The two-half capability probe stays as the defensive gate for mismatched deployments — and the capability spec now exercises its TRUE path against the published package in CI. * 🛅 feat: Park-and-Claim Steer Recovery + Host-View Content Reads Codex round 8 (6 fixed incl. both P1s, 1 push-back): - The long-deferred no-subscriber gap is closed: every terminal drain (final, aborted-final, error, abortJob, resumed finalize) PARKS acknowledged leftovers on the job hash (unrecoveredSteers), and the status route claims them exactly once for inactive jobs — a client that closed/reloaded past the transient final event restores its steers as queued chips within the post-terminal TTL. A replacement run clears the parked copy (a live client started it). - Same-instance content reads are steer-complete: RedisJobStore now caches the HOST content array (WeakRef) via setContentParts and prefers it over the SDK graph cache, whose view never contains host-authored steer parts; the graph fallback splice-INSERTS steer chunks at their recorded host-view indices (the graph array is unshifted, so assignment would overwrite SDK parts). - Replay token accounting now counts prepended file-context text: full stamped content minus the steer body (already counted), so large steered documents hit the budget instead of bypassing pruning. - The queue drain restores an item when ask() refuses without sending (history not yet in cache after navigating back) — text is never silently dropped. - The armed interrupt flag travels WITH a parked run-end signal, so another run on the same pane can neither consume nor clear it. - parseTextParts extracts steer text (search indexing / audio). * 🎛️ refactor: Single Send Slot + In-Thread Steer Messages - Merge the during-run send affordance into the send/stop button slot: with composer text the send button replaces Stop (Enter = default action), hover reveals Steer/Queue/Interrupt rows with shortcuts; drop the separate DuringRunActionsMenu chevron - Add during-run keyboard chords: Cmd/Ctrl+Enter = non-default action, Alt+Enter = interrupt & send (plain-Enter submitters only) - Render steers as standard user messages in the thread: SteerPart (icon + author header + user text presentation) replaces the SteerBubble, and submitted steers appear immediately at the projected injection point via the PendingSteers slot on the streaming message - Keep composer rows only for recoverable states: failed steers (retry/edit/queue) and queued follow-ups * 🩹 fix: Keep the Replacement Submission Alive Across Abort Settlement The aborted run's final SSE event fires before the abort HTTP response resolves, so an armed interrupt & send drains and starts the NEXT submission while the abort POST is still in flight. The response handler's unconditional clearAllSubmissions() then reset the new submission, aborting its stream attach before the subscribe — the follow-up ran and persisted server-side but the live placeholder finalized empty (content appeared only after reload). useAbortCleanup captures the submission before the abort round-trip and both settlement paths (success and 404-catch) clear only when the captured submission is still current; a replacement stays untouched. Plain Stop behavior is unchanged. * 🧭 test: Playwright E2E for Mid-Run Steering and Queuing - Add e2e/specs/mock/steering.spec.ts: steer mid-run (202 + immediate in-thread pending part + real MCP tool boundary + words survive run end), Cmd/Ctrl+Enter queue with auto-send after clean completion, and Alt+Enter interrupt & send with the follow-up streaming into the live view - Add the E2E_STEER_TOOL_REPLY fake-model marker: slow preamble, a real remember_fact MCP tool call (PostToolBatch boundary), then a final turn - Test 1 pins the run-end degradation contract while the SDK's top-level agentId stamping bug blocks live injection; its header documents the assertions to flip once the fixed SDK is pinned * 🧷 fix: Job-Independent Steer Recovery + Expiry and Resume-Gap Parking Codex round 10: the park-and-claim recovery had lifecycle holes. - Move parked steers off the job hash onto their own bounded-TTL store key (JOB_CREATE_LUA resets it; deleteJob leaves it alone): the default completeJob path deletes the job record immediately, and the Redis read path never deserialized the old hash field — recovery previously worked only with STREAM_KEEP_COMPLETED_JOBS on the in-memory store - Carry the owner identity inside the parked payload and authorize the claim against it, so the status route recovers steers on its jobless branch too (the common reload-after-terminal case); a non-owner claim returns nothing and re-parks the payload - Park queued steers on approval expiry: snapshot the frozen queue before the requires_action→aborted CAS (whose terminal cleanup drops the steers key) and park only when the CAS wins - Mirror the terminal drain/park block in resume.js's failure path, which previously let completeJob's backstop clear 202-accepted steers - Close the Redis snapshot→subscribe resume gap: re-peek the queue after attaching and re-surface missed on_steer_applied events from the durable content view (synthesizeAppliedSteerEvents), updating resumeState.pendingSteers to the live queue * 📌 chore: Require @librechat/agents 3.2.63 + Applied-Steer E2E Contract - Bump the @librechat/agents pin to ^3.2.63 in api/ and packages/api/: it scopes the hook agentId marker to subagent child graphs, so the steering drain hook fires at top-level tool-batch boundaries and mid-run injection is active (danny-avila/agents PR 307) - Flip e2e steering test 1 from the documented degradation contract to the applied-steer contract: the optimistic in-thread part transitions to the persisted part at the tool boundary and survives inside the response after run end, with no queued follow-up turn * 🎗️ feat: Steered Messages Join the Message-Nav Ribs Steers are user messages, so they get their own clickable rib on the navigation rail, interleaved at their in-thread position inside the response that absorbed them (one DOM query in document order). SteerPart anchors itself as #steer-<id> with a steer-render marker — both the optimistic pending entry and the persisted part — and the rib carries the user role label with a preview drawn from the steer's text body, skipping the author header. * ❎ feat: Cancel a Queued Steer Before Injection + True User-Message Alignment - Add POST /chat/steer/cancel: removes ONE still-queued steer by id via an atomic list rebuild (Redis Lua preserves order and TTL), authorized against the job owner; removed:false is advisory — the cancel lost its race to the drain or the run end, never an error - Surface an × on the in-thread pending steer (server-acknowledged entries only): optimistic removal, restored if the POST fails since the server would still inject the words - Outdent SteerPart past the response's icon column so steers sit flush with top-level message rows, reading as regular user messages * 🧯 fix: Round-11 Recovery Hardening + Provider-Free Pending Slot - Reconcile the resume steer gap by steerId SETS, not queue length — a steer added in the gap (or an equal-length drain+enqueue swap) now refreshes resumeState.pendingSteers and still synthesizes the missed on_steer_applied events - Make completeJob's terminal backstop park: direct error-path callers without the controllers' close-and-park no longer silently clear 202-accepted steers (createdAt-guarded closeAndDrain + owner park before the terminal write) - Persist the steer part BEFORE media encoding in the drain hook: an abort inside the encode window can no longer lose a file-steer (the part refs come from the enqueue-sanitized item; replay re-encodes per turn unchanged) - Move the parked-claim owner check INSIDE the atomic store claim (substring gate in the Lua / in-memory equivalent): a non-owner probe can no longer transiently delete the recovery payload; the app-side parse stays authoritative - Park queued steers in BOTH stores' own requires_action expiry cleanup, which bypassed the manager-level sweep - Sweep expired parked steers from the in-memory store's periodic cleanup; restore a queued chip when send-now's submit is refused; upsert steer ACKs so an SSE reconnect reseed cannot duplicate chips - Mount the cancel mutation per steer item so the pending slot needs no QueryClient on ordinary streaming renders (fixes the CI failure in ContentParts.integration.test) - Skipped delivery-gated parking (finding 8): transport receiver counts cannot prove browser delivery, and gating the only durable copy on them trades cosmetic chip resurrection for real text loss; the window is already bounded by claim-on-read, createJob reset, and the TTL * 🩺 fix: Annotate PARKED_STEERS_TTL_MS for isolatedDeclarations tsdown's d.ts generation requires explicit types on exported consts with computed initializers; tsc --noEmit does not run that check, so the round-11 export slipped past local verification and broke Build packages (and every downstream CI job that consumes the built dist). * 🛟 fix: Round-12 Terminal-Path Recovery + Durable Steer Events - Park queued steers before the stale-running reap deletes a crashed or hung job in BOTH stores — the one terminal path with no controller finalization; requires_action expiry parking refactored onto the same snapshot/park helpers - Enqueue instead of dropping when a steer fallback send is refused: both the NO_ACTIVE_RUN branch and the settled-run rejection branch now observe sendNow's false return - Recover on the SSE reconnect-404 terminal path: convert local pending steers to queued, claim parked steers via /chat/status, and write a non-completed run-end signal so interrupt flags release without auto-sending an unknown outcome - Fall back to a positive parked-recovery TTL when completedTtl is 0 (SET EX 0 is invalid and silently killed recovery) - Make on_steer_applied durable before publish: emitChunk gains a durable option that awaits the chunk-log append (best-effort) ahead of the transport publish; the default delta path stays fire-and-forget * 🔐 fix: Round-13 Steer Authorization + Trusted File Refs - Resolve client-supplied steer file refs against the DB owner-scoped at enqueue and queue only DB-derived shapes (same filter as the injection fetch, shared via refs.ts); any unresolved id fails loud with 400 — spoofed type/filepath metadata can no longer be persisted into assistant content or rendered in chat/share views - Enforce agent authorization on /chat/steer against the ORIGINATING run's job identity: the chat path's role gate (AGENTS:USE, with the same non-agents-endpoint skip) plus the per-agent ACL check with the capability bypass — revoked access mid-run can no longer inject; cancel stays ownership-only (nothing model-bound) - Mark steered uploads used after a successful enqueue (owner-scoped, best-effort) so the upload-window TTL cannot reap a file the persisted steer part references - Consume the parked recovery copy after live delivery: converting final/abort/error pendingSteers fires one owner-gated claim-on-read, so dismissed chips can no longer resurrect on a later reload * 🎙️ fix: Round-14 Composer-Context Fidelity + TTS and Queue-State Gaps - Keep steer text out of generic assistant text extraction: parseTextParts excludes STEER parts by default with an includeSteer opt-in for the full-record surfaces (Meili indexing, aborted-response persistence) — TTS callers no longer speak the user's own mid-run words - Mark queued uploads used at enqueue time via a minimal owner-scoped POST /files/usage (fail-closed without a user; upload limiters do not apply to a metadata touch), fired once wherever composer files enter the queued state — the upload-window TTL can no longer reap a file waiting out a long run or approval pause - Carry quote chips and manual skill picks on queued items: captured and consumed from the composer at queue/interrupt time exactly like files, threaded through the drain and send-now overrides, and restored by the queued row's Edit message - Key an early-aborted FIRST turn's run-end signal to NEW_CONVO (resolveRunEndTarget) so queued follow-ups stay visible on the restored new-chat composer instead of parking under an optimistic stream id the user never sees again * 🧿 fix: Round-15 Gap Coverage + Consolidated Sweep (Share Leak, Abort Ids, Chip Hygiene) - Run the resume steer-gap check for every still-active job: an empty snapshot no longer skips the re-peek, and synthesis now keys on the FRESH content view so an applied-in-gap steer that was never snapshotted still re-surfaces (over-emission is benign — applied-id dedupe, index-stable parts) - Thread queued context through steer degradation: sendQueuedNow passes the item's quotes/skills into submitSteer, and every fallback (requeue or settled send) restores them instead of dropping to text+files - Stop shared links from leaking steer attachment refs: the share snapshot now walks content — files-excluded shares strip steer-part files entirely; files-included shares sanitize and share-route them like top-level files (copy-on-write, non-steer content by reference) - Seed pending-steer chips unconditionally on load/return so a steer applied while away cannot linger as a stale chip beside its part - Use the abort response's resolved job id: chips/drain-signal land where the user actually is (NEW_CONVO for a new-held first turn, consistent with resolveRunEndTarget) while the parked-copy claim hits the resolved id instead of a no-op /chat/status/new - Open steered documents like normal message files (FilePreviewDialog) - Cap the applied-steer id set on the live path via a shared helper; kept surviving run end deliberately (late-ACK race depends on it) and fixed the atom comment that claimed otherwise * 💡 fix: Un-light Steer Ribs When Their Node Is Replaced Two stacked gaps kept a steer rib lit after scrolling away: the pending→applied swap replaces the DOM node under the same id, which produces no IntersectionObserver exit and — because the entry list dedupes on (id, preview) — no entries change either, so the observer kept watching a detached node; and the rail's mutation filter only reacted to .message-render nodes, so steer-node swaps and removals never triggered a refresh at all. - reconcileObservedElements re-points the observer at replaced nodes from the mutation-driven refresh regardless of entries identity, dropping stale visibility until the fresh node reports (the observer fires its initial intersection immediately, so a truly visible part re-lights within a frame) - The mutation filter now recognizes steer-render nodes alongside message rows * 🪪 fix: Round-16 Recovery Owner Fields + Context Stickiness + Share Labels - Park resumed-run leftovers with the manager facade's metadata owner fields: a bare job.userId is undefined on that shape, which made every parked payload from a resumed HITL run unclaimable - Keep a queued item's quotes/skills sticky through a successful steer ACK: the pending chip carries them (client-only), reseeds preserve them across reconnects, and every terminal conversion — local or server-list, merged by steerId — restores them onto the queued item - Convert resumeState.pendingSteers on the inactive status branch (deduped against unrecoveredSteers) so steers observed in the expired-pause-before-sweeper window convert instead of vanishing until a later reload - Label shared steer parts share-safely via the existing ShareContext: a viewer's own name no longer appears on the sharer's steered messages * ✂️ fix: Carry Steer Context Through the Failed-Chip Edit Action Retry and convert-to-queue already preserve a failed steer's carried quotes/skills;

Danny Avila	988a14a405	🙋 feat: ask_user_question - agent-initiated questions with durable pause/resume (#14139) ... * feat: ask_user_question tool — agent-initiated questions with durable pause/resume The HITL runtime merged in #13942/#14024/#14025/#14123 already ships the full ask_user_question lifecycle (payload-agnostic handleRunInterrupt, resume validation via mapAskUserAnswer, reconnect rehydration, and the client question card) — but nothing ever raised the interrupt. This adds the producer: - packages/api/agents/hitl/askUserQuestionTool.ts: LLM-callable tool whose func calls the SDK askUserQuestion() helper (LangGraph interrupt() from the tool body); zod schema with length caps mirroring AskUserQuestionRequest, plus a JSON-schema twin for the schema-only registry - Registration: agentToolDefinitions, manifest.json (Tools dialog, admin filteredTools/includedTools kill switch), basicToolInstances, handleTools constructor branch - run.ts gating: checkpointer now attaches for hitlCapable runs whose agents carry the ask tool even with the tool-approval policy disabled (the interrupt needs only durability, not humanInTheLoop/hooks); the tool is stripped fail-closed from non-HITL callers (OpenAI-compat/Responses) and subagent child configs; excluded from eager event execution (interrupts must be raised inside the Pregel task frame) - resume.js: 16k length cap on the answer wire field - e2e (real Run + FakeChatModel + LazyMongoSaver + supertest resume): tool-body interrupt pauses durably with NO approval policy, answer round-trips as the ToolMessage content, tool body re-runs once on resume, sequential questions re-pause * fix: adversarial-review findings — in-graph execution, orphan prunes, endpoint scoping, real kill switch Pre-PR multi-agent review confirmed 5 defects in the initial commit; all fixed: 1. CRITICAL — the tool never paused on the real agents endpoint: production loads tools definitions-only, flipping the SDK ToolNode to event-driven dispatch, and the host ON_TOOL_EXECUTE handler runs outside the Pregel task frame (under runOutsideTracing), where interrupt() throws and becomes an error ToolMessage. Reworked: the ask tool never rides toolDefinitions/ toolRegistry — on HITL-capable top-level agents a real instance is supplied via AgentInputs.graphTools (agents#289, requires @librechat/agents > 3.2.57), the SDK's in-graph direct-tool seam; new production-shape e2e pins the event-driven mode end to end. 2. CRITICAL — ask-only runs left orphaned interrupted checkpoints (silent context duplication on every later turn): both orphan prunes were gated on toolApproval.enabled. The pre-turn prune now also fires for ask-capable agents (exported agentRequestsAskUserQuestion), and the abort-route prune fires when the aborted job carries a pendingAction. 3. MAJOR — self-spawned subagents bypassed the strip (self config resolves from the parent's _sourceInputs): fixed SDK-side (buildChildInputs clears graphTools) and the tool is now never present on child surfaces host-side. 4. MINOR — the manifest entry leaked into the Assistants tools dialog and the legacy plugins endpoint, where tools execute with no run to pause: new agentsOnly manifest flag, scoped out of both listings. 5. MINOR — filteredTools/includedTools only hid the tool from the dialog: now enforced at run build (strip + no checkpointer), making the admin filter a real kill switch for already-saved agents. * chore: update @librechat/agents dependency to version 3.2.58 in package-lock.json and package.json files * fix: reject agents-only tools at assistant create/update (Codex round 1) The tools-dialog scoping keeps ask_user_question out of the assistants LISTING, but the v1/v2 create/update handlers resolve arbitrary posted tool strings from the shared getCachedTools map — a REST client or stale saved payload could still attach it, and the assistants runtime executes tools with no run to pause, so every call would error. New isAgentsOnlyTool(tool) (manifest-driven, handles string and function-object shapes) drops such tools with a warn at all four resolution sites (v1+v2, create+update). * fix: offset resumed-run content indices past the pre-pause seed A resumed run rebuilds the graph from the checkpoint, and the fresh graph numbers content indices from its own empty contentData — starting at 0. The resume path seeds the (also fresh) content aggregator with the pre-pause parts at exactly those indices, so the resumed model turn collided with the seed: type-matching parts silently MERGED (post-resume text appended into a pre-pause text block), and type-mismatching parts (a reasoning/think part at index 0 — any Anthropic reasoning agent) dropped EVERY delta with 'Content type mismatch', losing the entire post-resume output from the live stream and the saved message. Latent since #13942 — tool-approval resumes corrupt content the same way (probe-verified); it surfaced now because ask_user_question makes pausing a first-class flow and reasoning models make the loss total. - createContentIndexOffsetHandlers(handlers, offset): wraps ON_RUN_STEP (the single point where a content index enters the pipeline — deltas resolve through the aggregator's stepMap) and ON_AGENT_UPDATE's inline index; every other handler passes through by reference. Probe-validated: resumed output now lands as a new part after the paused tool call. - resumeCompletion wires it with offset = seedContent.length. - logToolError: a GraphInterrupt unwinding out of a tool body is the HITL pause working as designed — no longer logged as a Tool Error. * fix: unblock live streaming of the resumed segment after an answer With resume indices now ABSOLUTE (server continues after the pre-pause parts), the synthetic ask-user-question card was squatting on exactly the index the resumed segment streams into: applyAskUserQuestion appends the card at the end of the message content, so on the answering device every incoming part at that index was blocked and nothing rendered between the answer submission and the finalize replacing the message. removeAskUserQuestionPart(message, actionId) strips the pause-scoped card on successful answer submission (useResumeSubmit onSuccess) — the durable record of the Q&A is the ask_user_question tool call itself. Pure helper + specs; same-reference no-op when nothing matches. * fix: displace the synthetic question card in the streaming content writer The store-level strip on answer submit wasn't enough: the SSE step handler keeps its own in-flight copy of the streaming message, so on the answering device the synthetic ask-user-question card still occupied the ABSOLUTE index the resumed segment streams into — every delta warned 'Content type mismatch' (existing ask_user_question vs incoming text) and nothing rendered between the pending_action and finalize. Displace the card inside updateContent when any real part claims its slot — the same displacement pattern as the OAuth prompt part directly above it. Covers the streaming handler's own copy, reconnecting tabs, and other devices; once real content streams, the pause is over by definition. Spec drives a runStep + text delta into the card's index and pins: no mismatch warn, card gone, text rendered. * feat: dedicated UI + durable data for completed ask_user_question calls The completed ask call rendered as a generic tool card labeled 'Cancelled' with raw (and empty) JSON args. Two layers fixed: Data: the saved tool_call part had args:'' and no output — streamed arg chunks carry no tool name so the aggregator drops them (normal tools recover via the completion event, which never fires for a tool that interrupts mid-execution and resumes on a rebuilt run with no step id). The resume controller now stamps the paused ask part with the pendingAction's authoritative question as args and the user's answer as output (attachAskUserQuestionAnswer — pure, targets the newest unanswered ask part, so sequential questions each keep their own answer). UI: Part.tsx routes ask_user_question tool calls to AskUserQuestionCall — a compact Q&A record ('Asked a question' header, question, description, 'You answered: <label>' preferring the picked option's label, or 'No answer was given' for an abandoned pause) instead of the generic card. New i18n keys; parseAskUserQuestionArgs degrades to null on malformed model args. * fix: single question UI per pause + immediate answer display Two live-turn issues with the new durable Q&A card: 1. Duplicate question on ask: during a live pause the message carries BOTH the ask tool_call part (now rendered by AskUserQuestionCall, showing a misleading 'No answer was given' while paused) and the synthetic interactive card. The durable card now defers while the turn is live and unanswered (isSubmitting) — the interactive card owns the question UI until it's answered; an abandoned pause still shows its no-answer state once the turn settles. 2. 'No answer was given' after answering: the server stamps the answer onto the part at resume seed, but the client only received that at finalize. No stream emission needed — the client knows the answer it just submitted: resolveAskUserQuestionPart (replacing the plain strip on submit success) removes the synthetic card AND stamps output/progress onto the newest unanswered ask tool_call, seeding args from the synthetic part's question when the streamed args were lost — mirroring the server-side attachAskUserQuestionAnswer, so the Q&A record shows the answer the moment the user submits. * fix: keep the Q&A record visible while the resumed segment streams The optimistic output stamp lives in the message store, but the SSE step handler evolves its own cached copy of the streaming message (created at turn start) — the first resumed event overwrites the store with that copy, wiping the stamp, so the Q&A card blinked out during streaming and only returned at finalize. Render-layer fallback instead of fighting the handler's copy: submitted answers are recorded by ask tool_call id when resolveAskUserQuestionPart stamps the part, and AskUserQuestionCall reads the recorded answer whenever the part's own output is missing — the record survives any message-copy churn until finalize delivers the server-stamped part. * feat: present Ask User as a native builtin in the tools dialog It ships with the app and pauses the run like a first-class feature, so it belongs with the builtins (Run Code, Web Search, Memory, ...) rather than in the third-party plugin list — while its mechanics stay exactly a plugin's: - BuiltinId += 'ask_user_question' (documented exception: a native TOOL, not a capability; selection reads agent.tools, the toggle emits tool-add/remove patches instead of a capability field) - buildCatalog surfaces it as a builtin gated on the same signals as before (tools capability on + the server lists the plugin, i.e. not admin-filtered) and skips it in the plugin loop so it never double-lists - On-theme icon: lucide MessageCircleQuestion in a teal chip via the builtin icon map, matching the other native entries; the bespoke purple SVG and the manifest icon field are gone - i18n'd name/description keys like the other builtins * feat: composer popover for answering questions (mentions-style) Answering moves to the composer, matching the existing mentions/prompts popover pattern: while an ask_user_question pause is live, a popover anchors above the textarea with the question as its header, numbered option rows (hover/click, or ↑/↓ + Enter from the empty composer), and an × to dismiss. The main textarea doubles as the free-form answer — its placeholder flips to 'Something else...' and form submit routes the text to the paused run as the answer instead of starting a new turn. Dismissing (× or Escape) restores normal sends; the inline transcript surfaces stay as before (interactive card while paused, durable Q&A record after) so the question remains visible in history. - findLiveAskUserQuestion (pure, spec'd): newest unanswered synthetic part across the conversation IS the popover signal — applied on on_pending_action, stripped on answer submit, so visibility tracks the pause lifecycle with no extra state - useLiveAskUserQuestion hook shared by the popover and ChatForm; dismissals in a recoil atom so both react - popover only mounts on the primary composer (index 0), mirroring QuoteButton * feat: number-key selection + return glyph in the question popover Pressing 1-9 in the empty composer picks the matching option directly, mirroring the numbered row chips; the highlighted row shows a return-key glyph as the Enter affordance. Same empty-composer guard as the arrow keys — typing a free-form answer is never intercepted. * refactor: first-class composer answer mode (useAskAnswerMode) Replaces the bolted-on integration (inline onSubmit interception + raw capture-phase keydown listeners on the textarea ref) with a single hook that owns the whole answer mode: live-question derivation, dismissal + highlighted option (shared recoil state), option selection, free-form submit routing (submitText returns whether it consumed the submission), and keyboard handling (handleKeyDown returns whether it consumed the key, composed ahead of the textarea's normal handler — no more addEventListener). The popover is now pure rendering off the hook; ChatForm wires placeholder, onKeyDown, and onSubmit through the same instance. Deliberately scoped to the composer rather than useSubmitMessage: starters/prompt-commands keep new-turn semantics (and the existing job-replacement behavior while paused). * fix: Codex round 2 — inline answer input, approval exemption, pause-time args F1 (composer submit unreachable while paused — isSubmitting keeps Stop shown and useTextarea eats Enter): redesigned around it, borrowing Claude Code's AskUserQuestion semantics. The popover now owns free-form input via an inline 'Other' row (numbered last, 'Something else…'), with select-then-confirm rows (click/arrows/digits highlight; Submit ↵, Enter, or double-click fires; Skip dismisses). The composer returns to being a plain composer — no placeholder swap, no submit interception; Stop keeps meaning stop. F2: ask_user_question is exempt from the tool-approval prompt unless the admin explicitly lists it (allow/ask/deny all win) — approving the right to ask a question was a pure double pause; the tool is side-effect-free. F3: the question is stamped onto the paused ask tool_call's args at PAUSE time (attachAskUserQuestionArgs in handleRunInterrupt), so abandoned/expired/ stopped turns persist with the question intact and the record card can render it — previously only the answer-resume path stamped args. * fix: fold model-supplied 'Other' options into the inline free-form row The model can generate its own catch-all option ('Other (type your own)', value 'other'), duplicating the popover's built-in free-form row — two other-ish rows, one pickable as a literal answer. Two layers: - Tool description now tells the model NOT to include catch-all options (the answer UI always offers free-form input on its own) - splitOtherOption (pure, spec'd) folds a catch-all option that arrives anyway out of the choice rows and uses its label as the inline input's placeholder — conservative match (value 'other', or a label reading as a free-form invitation), no false positives on real choices * fix: single question surface + clean free-form-only popover Two live-pause confusions: (1) the inline transcript card and the composer popover both rendered — the card now defers while the popover is up for its action, returning as the fallback surface when the user dismisses the popover (and in contexts without a ChatContext, where the popover can't exist); (2) an options-less question showed a pointless numbered '1 Something else…' row — free-form-only questions now render the inline input alone, with the 'Type your answer…' placeholder (a folded model 'Other' label still wins). * feat: the composer is the free-form answer box (like the main chat input) While a question pause is live, the main chat textarea composes the free-form answer — placeholder swaps to 'Something else…' (or a folded model 'Other' label), Enter with text submits the answer through answer-mode key handling (composed BEFORE useTextarea's submitting-lock, so the lock can't swallow it), and the Stop button swaps to Send (enabled despite isSubmitting) per the select-then-confirm design. The popover slims to the question header, numbered option rows, and Skip/Submit — its inline input is gone since the composer owns free-form now. Dismissing the popover restores normal composer semantics (Stop button, normal sends). * fix: Codex round 3 + real Skip semantics - Skip now ANSWERS instead of hiding UI (danny): it resumes the run with a decline notice ('The user chose not to answer this question.') so the model moves on — a client-side dismiss left the run paused until expiry, a hung turn. × / Escape remain pure dismiss (switch to the inline card surface). - P1 (resumed approval tool indices): resumed tool_calls steps whose tool_call id matches a seeded UNRESOLVED part now rebind to that seeded slot instead of offsetting — the original part resolves in place (output attaches) and no duplicate appears; message steps keep the offset, so the text-loss fix stands. createContentIndexOffsetHandlers now takes the seed array; resolved seeded calls are not rebind targets. - P2 (stale selection across questions): selection state resets when the live actionId changes; the vestigial inline-Other state ('other' selection + text atom) is gone — the composer owns free-form. - P2 (Redis abort path loses the args stamp): the abort route re-stamps the question onto the ask tool_call in the reconstructed abort content, so a Stop-abandoned question persists with its question intact. - P2 (malformed args crash): parseAskUserQuestionArgs normalizes untrusted shapes (options: {} / non-string entries) instead of throwing in render. * feat: free-form hint in the question popover footer Left-aligned in the footer row (opposite Skip/Submit): 'Or type your answer below' — points open-ended answering at the composer, whose placeholder already reads 'Something else…'. * feat: preserve composer drafts across the answer-mode swap The answer phase gets its own draft key (ask-answer:<actionId>), passed as a draftId override into useAutoSave — the key change itself drives the existing save/restore machinery, so the conversation draft (or mid-run PENDING draft) is stashed when a question pause takes the composer and restored once the user answers, skips, or dismisses. Ask keys are exempt from the PENDING migration branch, which would otherwise move-and-delete the stashed draft. A half-typed answer survives reload/navigation while its question stays live. Answer submission (option pick, free-form, skip) resets the composer via a new non-throwing useOptionalChatFormContext, so the swap-back restores into an empty box even outside ChatView-less render contexts (Share/search). * fix: rebind resumed steps for ALL seeded tool call ids The resume controller pre-stamps the user's answer onto the seeded ask_user_question part, so the unresolved-only rebind predicate treated it as settled and shifted the tool's re-run step to a fresh offset slot, leaving a duplicate ask record in streamed/saved content. Tool call ids are provider-minted per call: a resumed step bearing a seeded id can only be the interrupted batch re-executing, so rebinding every seeded id is always correct. * feat: popover UX round 4 — clickable hint, collapse, click-submit, multiSelect - Footer hint is a button that focuses the composer; reads 'Type your answer below' (no 'Or') when the question has no options. - Collapse (chevron) hides the popover WITHOUT closing the pause: answer mode stays live (placeholder, Enter routing, draft key), the chat card renders the question with a ChevronUp affordance to re-expand. x remains dismiss. - Single-select options submit on a single click; the Submit button renders only for multi-select. - multiSelect end-to-end: tool zod schema + JSON definition twin, wire type, client parse, popover check-chips, card toggles, record-card label mapping; answer = option values joined ', '; composer Enter and the multi Submit button both fold free-form text in with the checked values. - Hardening from adversarial review: in-flight status guard on every submit path (no duplicate resumes on double-click), popover locks while submitting, collapsed mode disarms invisible digit/arrow steering, the card shares the hook's checked state while the pause is live, the card folds catch-all 'Other' options, record mapping is all-or-nothing to avoid phantom labels, composer resets only when its text was consumed or the draft machinery will restore the stash. * feat: ask_user_question in model specs and ephemeral agents A librechat.yaml modelSpec can now equip the tool the same way it equips webSearch/executeCode/fileSearch/memory: modelSpecs: list: - name: my-spec askUserQuestion: true loadEphemeralAgent pushes the tool name when the spec flag (or the ephemeralAgent request flag, wired for parity) is set; everything downstream is the existing persisted-agent machinery — createRun's hitlCapable gating, graphTools injection, checkpointer attach, subagent strip, and the admin filteredTools/includedTools kill switch all apply unchanged. * feat: tense-aware Q&A record label (Asking / Asked) Shorten the record card header per feedback: 'Asking' while the question is still unanswered (abandoned/awaiting), 'Asked' once answered — replacing the single 'Asked a question' label. * fix: Codex round 4 — added-agent ask parity + preserve answer on failed resume F1 (added.ts): mirror loadEphemeralAgent's ask_user_question branch in the added-agent loader so a model spec's askUserQuestion flag (or the ephemeral request flag) equips added top-level agents too, matching execute_code / web_search / memory. Two load.spec cases added. F3 (composer): submitAskAnswer now takes an onSuccess callback and useAskAnswerMode defers clearing the selection/composer until the resume is accepted. A failed resume (16k answer-cap 400, expired action, network error) leaves status re-answerable, so wiping the composer up front lost the user's only copy of a free-form answer; now it survives for trim/retry. (F2 — a claimed Tools-capability bypass — was verified NOT reproducible: agentRequestsAskUserQuestion matches only loaded instances/toolDefinitions/ toolRegistry, all capability-filtered; a raw tools string has no .name and never triggers the install. Replied on-thread with the probe evidence.) * fix: Codex round 5 — expired question exits answer mode so its message shows An expired question (e.g. resume returns the stale-action 409) previously left the popover open with locked controls and no explanation, because the chat card — which carries the only 'this action expired' message — was suppressed by the popover-open guard. Treat 'expired' as no longer active: the popover closes, the composer reverts to normal, and the card becomes the sole surface and renders the expired message. 'error' stays active (retryable). * feat: group ask_user_question calls as their own category A homogeneous group of ask_user_question tool calls now reads 'Asked N questions' (present tense 'Asking N questions' while the turn streams) with a question glyph and no raw-name suffix — mirroring the subagent 'Ran N agents' category treatment, instead of 'Used N tools — ask_user_question'. Mixed groups keep 'Used N tools' but humanize the suffix to 'Question' and show a question icon for the ask entries (TOOL_FRIENDLY_NAME_KEYS + ToolIcon map). A group only forms at count >= 2, so the plural is always grammatical. Three ToolCallGroup.test cases cover homogeneous label/icon/suffix, present tense while streaming, and the mixed-group fallback. * fix: Codex round 6 — composer submit lock + abort stamp before emit F7 (composer status lock): the ask submit status lived on ApprovalContext, a React context mounted only around message content (ContentParts). The PRIMARY answer surface — the composer in ChatForm — renders outside it, so useApprovalContext returned the inert FALLBACK: status was always 'idle', setStatus a no-op. The in-flight double-submit guard (round 4) and the expired-exits-answer-mode fix (round 5) therefore never engaged for the composer. Move ask submit status to a global Recoil atom (useAskSubmitStatus) read/written by the composer, the popover, and the card alike, so a fast double-click/Enter is actually blocked and expired/error surfaces on every surface. Tool-approval status stays on the context (unchanged). F5 (abort stamp before emit): the abort route re-stamped a paused ask_user_question's args AFTER GenerationJobManager.abortJob had already emitted the final SSE from the unstamped content, so a Redis/cross-replica Stop left the live client showing an empty question until reload. abortJob now takes an optional transformAbortContent applied to the persistable content BEFORE the final event is built (and returned), so the live client and the saved message agree. New abort.spec case + updated call assertions. * feat: gate ask_user_question behind its own agent capability Add a first-class AgentCapabilities.ask_user_question (in defaultAgentCapabilities, on by default) so admins can enable/disable questions independently via endpoints.agents.capabilities, exactly like execute_code / web_search — not lumped under the generic tools capability. - ToolService: both filteredTools predicates (definitions-only and instance loaders) gate ask_user_question on checkCapability(ask_user_question) before the generic tools fallthrough. When off, the tool is dropped from toolDefinitions/toolRegistry, so run.ts's agentRequestsAskUserQuestion (which keys on the loaded surface) declines to install it and attach a checkpointer — the capability is enforced end-to-end at the loader, no run.ts change needed. - Tools dialog catalog: surface the ask builtin under its own capability rather than the generic tools one, so the UI matches the backend gate. - Tests: ToolService capability on/off filtering + defaults membership; catalog builtin visibility keyed on the dedicated capability. * style: sort imports in ToolCallGroup.test (CI import-order gate) * fix: Codex round 7 — surface ask-answer errors in the open popover A failed answer submission (16k reject, network error) sets the ask status to 'error', which — unlike 'expired' — deliberately keeps the question active and retryable. But the chat card that renders the error message is suppressed while the popover is open, so a composer/popover answer failed silently. Expose an 'errored' flag from useAskAnswerMode and render a warning line (com_ui_ask_answer_error) in the popover, so the user gets feedback and retry guidance without having to collapse/dismiss. It clears automatically on retry (status flips to 'submitting'). * fix: Codex round 8 — respect IME composition before submitting answers handleComposerKeyDown runs before useTextarea's composition guard, so with a CJK/IME keyboard the Enter that commits an in-progress composition was being intercepted and submitting the partial answer (and the composition buffer can leave value empty mid-compose, mis-triggering digit/arrow steering too). Bail at the top when composing — nativeEvent.isComposing, or key==='Process' / keyCode===229 for Safari's inconsistent reporting — mirroring the existing composer guard so the character commits normally. * chore: update `@librechat/agents` to v3.2.60 * 🔧 chore: Update @opentelemetry/core to version 2.9.0 and clean up package-lock.json * feat: digit shortcuts select options when the popover has focus Previously a number key (1..N) only selected an option from the empty composer (handleComposerKeyDown on the textarea) — if focus moved into the popover (a row/Skip/Submit button clicked or tabbed to), the number keys went dead. Add handlePopoverKeyDown, wired to the popover container's onKeyDown so it catches digits bubbling from the focused control: a digit activates its option exactly like a click (single-select submits, multi toggles). No highlight/Enter dance on this path — the options are buttons whose action is the click, and intercepting Enter would fight the focused button. Gated on active && !locked so it no-ops while a submit is in flight. * chore: update @librechat/agents to version 3.2.61 and @opentelemetry packages to latest versions	2026-07-08 15:31:05 -04:00
Danny Avila	bb7d99d56c	🫷 feat: Exclude File Authoring Tools From Eager Execution (#14051) ... * feat: exclude create_file/edit_file from eager execution Side-effecting host file-authoring tools should not be speculatively eager-executed: a write can land before the turn commits, and the eager path's incrementally-streamed args can diverge from the final tool call, tripping the SDK's 'changed after eager execution' guard so the model is told the write failed and loops (observed with create_file writing a large file to /mnt/data). Pass excludeToolNames so these tools run on the normal ToolNode path with the final args. Requires @librechat/agents with eager-exclusion support; older versions ignore the field. * chore: Bump `@librechat/agents` to v3.2.56 * refactor: reorder imports in run.ts for clarity * fix: also exclude execute_code/bash_tool from eager execution The eager 'changed after eager execution' corruption isn't specific to file authoring — any tool with a large free-form streamed arg is exposed. Observed live: a bash_tool heredoc (a full Python script in `command`) tripped the guard and the write never landed. execute_code (`code`) and bash_tool (`command`) carry large args and run code (side effects), so exclude them from eager alongside create_file/edit_file. * feat: wire codeSessionToolNames so create_file/edit_file share the code sandbox Activates the agents#283 capability: pass create_file/edit_file as codeSessionToolNames so their exec session/files fold into the shared code session and a file they write is visible to later execute_code/bash_tool calls (and the existing session is injected into their requests). No-op until @librechat/agents ships codeSessionToolNames (agents#283). * test: guard code-tool eager/session wiring in createRun Asserts createRun passes excludeToolNames (create_file/edit_file/execute_code/ bash_tool) and codeSessionToolNames (create_file/edit_file) to Run.create — the wiring the create_file->bash_tool sandbox-sharing chain depends on, which was silently missing before. Guards against a future edit dropping it. Mirrors the run-summarization test harness (mocks Run.create). The full create_file->bash_tool chain runs through the real code sandbox and can't run in the mock CI harness; the SDK mechanism is covered by @librechat/agents unit tests, and this guards the LibreChat wiring. * style: fix prettier formatting in run-codeTools test * chore: Bump `@librechat/agents` to v3.2.57	2026-07-01 11:07:30 -04:00

Danny Avila	6dbf9d5ad3	🪝 feat: Human-in-the-Loop Runtime - Tool Approval + Ask-User-Question (Slice B) (#13942) ... * chore: add @langchain/langgraph-checkpoint-mongodb for HITL durable resume * feat: HITL tool approval runtime — backend (Slice B) - endpoints.agents.checkpointer config + durable Mongo checkpointer (seam over the app connection; SDK MemorySaver fallback) with a TTL index + deleteThread pruning - HITL run wiring (PreToolUse policy hook + humanInTheLoop) attached in createRun, fully inert when toolApproval.enabled is off - interrupt gate (pause job -> requires_action + emit on_pending_action) and a resume route that rebuilds the run from the durable checkpoint and run.resume()s it - atomic single-winner resolve; agent-consistency guard; expireStaleApprovals terminal event; checkpoint pruned on every non-paused completion (thread_id == conversationId) * feat: HITL tool approval UI — frontend (Slice B) approve/reject/edit/respond + ask-user controls in the tool card (OAuth-button precedent), batch-aware single submit, live + reconnect (resumeState.pendingAction) wiring, and resume mutations posting to /agents/chat/resume. * fix(hitl): decouple ApprovalProvider from chat context ApprovalProvider is now pure state (safe to mount in provider-less / shared / test renders); the context-dependent submit moved to a useResumeSubmit hook the cards call. Part imports getAskUserQuestionPart from ~/utils/approval directly so suites that partial-mock ~/utils render Part without throwing. * fix(hitl): address Codex review — backend - P1: enforce per-tool allowed_decisions on resume (reject a crafted decision the policy disallows) via findDisallowedDecisions - prune the durable checkpoint on user-abort of a paused run, and before a fresh HITL turn, so a new turn cannot rehydrate an expired/aborted interrupt (thread_id is the stable conversationId) - persist + use isTemporary and the original parentMessageId on resume (temporary chats stay temporary; initializeAgent scopes thread files off the right parent) - generate a deferred first-turn title BEFORE completeJob so its event reaches the client and the final event carries the real title - moderateText: skip when there is no text (tool-approval resume) and moderate the ask-user answer, instead of denying on an empty input * fix(hitl): address Codex review — frontend - render ToolApproval for ANY paused agent tool card (bash/code/file/etc.), not just the generic ToolCall, by wrapping the tool-card branch in Part (moved the rendering out of ToolCall) - findPendingActionMessageIndex only matches an assistant message, never the user message (the underscore-strip could target the user bubble before the assistant placeholder exists) * fix(hitl): address Codex re-review - title eligibility checks the user message’s parent (first turn), not the response’s parent — the previous check could never be true and skipped title generation - use client.buildResponseMetadata() for the resumed message so contextUsage / thoughtSignatures survive (the abort-only helper dropped them) - moderate decisions[].responseText (the respond action’s user text) - give /chat/abort req.config (configMiddleware) so the HITL checkpoint prune on abort actually runs - read resume state BEFORE setContentParts so the in-memory store does not lose the pre-pause seed content - count resumes against LIMIT_CONCURRENT_MESSAGES (increment/decrement) so paused-then- resumed turns cannot bypass the limit - require actionId on resume so a body without it cannot resolve the current action * fix(hitl): address Codex re-review (round 3) — resume fidelity Bring the lean resume path to parity with sendMessage for things it bypassed: - carry userMCPAuthMap into the rebuilt run so approved MCP tools keep the user's creds - seed initialSessions (buildInitialToolSessions) so approved code/file/skill tools have the pre-pause uploaded-file context (esp. cross-replica / after restart) - await client.artifactPromises and persist them as response attachments (else tool artifacts created after the pause vanish on reload / for late subscribers) - merge metadata: cumulative usage (+ summary marker) from the job, contextUsage / thoughtSignatures from the client — fixes the round-2 regression that underreported post-resume cost * fix(hitl): address Codex re-review (round 4) — resume hardening - resume: require an EXACT paused agent_id match (reject omitted/ephemeral agent_id, not just a different one) and reject an endpoint mismatch, so a request can't rebuild the claimed checkpoint on a different graph - moderateText: also moderate a tool-approval decision's reject `reason` and stringified `editedArguments`, not just `responseText` - request: re-mark the paused response `unfinished:true` after BaseClient saves it as completed, so an expired / never-resumed approval doesn't leave a "finished" response in history; the resume path overwrites it on success * test(hitl): route-level integration test for the resume controller Adds api/server/controllers/agents/__tests__/resume.spec.js, a supertest integration test that drives the real ResumeAgentController over the full pause -> approve -> resume -> finalize lifecycle with the SDK run, durable checkpointer, Mongo, and concurrency cache mocked. The pure decision/liveness helpers run for real via requireActual, so the guard ladder is exercised end to end rather than stubbed. 25 cases covering: - the authorization / staleness / agent-and-endpoint / actionId guard ladder - tool_approval validation (undecided tool call, policy-disallowed decision) - ask_user_question answer requirement - the concurrency gate (429) and the atomic single-winner claim (409) - the happy path: ACK, run reconstruction, decision->SDK mapping, finalize (save the now-finished response, emit done, complete job, prune checkpoint) - first-turn title generation before stream completion - re-pause (no double finalize), abort-during-resume (no double finalize), and the resume-failure terminal path (emitError + completeJob + prune) * test(hitl): strengthen resume coverage + add approval util tests Acts on a self-audit of the new resume integration test. resume.spec.js (25 -> 32 cases): - replace the tautological emitDone assertion (it only checked the hardcoded `final: true`) with a structural check of the finalEvent payload — responseMessage content/id/unfinished, requestMessage identity, title - cover the previously-unwalked finalize branches: tool-artifact attachments (null-filtered), the aggregatedContent fallback when live content is empty, and client response-metadata attachment - add guard cases: unsupported pending-action type (400) and the pre-multi-tenancy null-tenantId pass-through (must not 403) - add error-path cases: first-turn title generation throwing must still finalize, and a completeJob failure during a resume error must force a terminal job state via the last-resort updateJob client/src/utils/approval.spec.ts (new, 15 cases): - applyPendingAction tool_approval: join by tool_call_id not position, skip completed calls, default allowed_decisions to [], referential stability when nothing changes - applyPendingAction ask_user_question: append, idempotent replace on replay, non-array content coercion - getAskUserQuestionPart type guard; findPendingActionMessageIndex assistant-only resolution (never resolves to the user bubble) * fix(hitl): address Codex re-review (round 5) Five findings verified against the code before fixing: - resume: require an EXACT endpoint match (like agent_id) — a resume that OMITS endpoint must not fall through, since the shared chat middleware treats a missing/non-agents endpoint as the ephemeral agent and could rebuild the claimed checkpoint on a different graph - resume: filter malformed content parts before saving the finished response, matching the normal AgentClient path (a resumed turn could otherwise persist an empty/invalid tool_call part that breaks reload/rendering) - resume: accumulate tool artifacts across pause segments — persist them on re-pause and MERGE (not overwrite) at finalize, so artifacts produced before a second approval pause aren't dropped by the next rebuilt client - approval (client): findPendingActionMessageIndex returns -1 when a provided responseMessageId isn't found, so the caller retries instead of attaching the prompt/approval to a prior assistant reply; fall back to the last assistant only when no responseMessageId is given - RedisJobStore: make appendChunk extend-only (XADD + EXPIRE-if-shorter via a single eval) so the on_pending_action chunk emitted after a pause can't reset the chunk-stream TTL back to the running window and evict pre-pause content before the approval is resolved Tests: +endpoint-omitted/unsupported-type/malformed-filter/attachment-merge/ re-pause-persist cases in resume.spec.js (36); ask-retry -1 semantics in approval.spec.ts (16); extend-only TTL assertion in the RedisJobStore Redis integration spec. * test(hitl): mongodb-memory-server integration test for the checkpointer seam The checkpointer unit spec covers config/selection with no DB connection; this exercises the durable Mongo seam against a real (in-memory) MongoDB — the part correctness actually depends on: - getAgentCheckpointer builds a real MongoDBSaver when Mongo is connected and setup() creates the TTL index (expireAfterSeconds) on the checkpoint collection - memory type returns undefined (SDK MemorySaver fallback) even when connected - saver is memoized per resolved config - deleteAgentCheckpoint prunes a thread's persisted checkpoint (the cross-turn isolation guarantee: turn N+1 on the same conversationId can't rehydrate it) - pruning is thread-scoped — deleting one conversation leaves others intact - undefined threadId is a no-op * fix(hitl): address Codex re-review (round 6) Four findings verified against the code before fixing: - messageFilterPii: scan the resume payload's user-authored text (ask-user `answer`, and a tool-approval decision's `respond` text, `reject` reason, and edited tool arguments) — the shared /resume route ran through the PII filter but it only inspected req.body.text, so a blocked token rode the resume payload back into the model/tool (mirrors the earlier moderateText fix) - resume: re-prime skill files invoked in the pre-pause segment before rebuilding the run, so an approved code/file-backed tool keeps the injected skill-file session refs instead of running without them (mirrors the normal path's primeInvokedSkills; the pre-pause content stands in for the message payload) - hitl: pin the graph identity. Persist a fingerprint of the graph-determining request fields (endpoint, agent_id, model, spec, ephemeralAgent — normalized) on the pending action at pause, and reject a resume whose recomputed fingerprint differs. This closes the ephemeral-agent gap, where agent_id is undefined so the id guard can't tell two ephemeral configs apart - resume: reject incomplete edit/respond decisions (findIncompleteDecisions) — an `edit` without an object editedArguments or a `respond` without non-empty responseText is 400'd before mapping, rather than defaulting to {} / '' and resuming with behavior the user never approved Tests: incomplete-decision + fingerprint match/mismatch cases in resume.spec.js (41); findIncompleteDecisions + computeAgentRequestFingerprint unit tests; and resume-field PII cases in messageFilterPii.spec.ts. * fix(hitl): address Codex re-review (round 7) Four findings verified against the code before fixing: - RedisJobStore: clear `agent_id` on createJob (add it to staleHitlFields). The job hash is keyed by conversationId and reused across turns; updateMetadata only writes agent_id when truthy, so a conversation that switched from a saved agent to an ephemeral/no-agent turn kept the old id and the resume guard rejected the valid pause as a different agent. (real correctness bug) - fingerprint: include `promptPrefix` in computeAgentRequestFingerprint, and re-send it on resume (ResumeAgentFields + buildResumeFields). Ephemeral agents derive their system instructions from promptPrefix, so a resume changing it previously passed the pin and rebuilt different instructions. (completes the round-6 fingerprint) - resume: the re-pause branch now persists the segment's accumulated CONTENT (filtered), not just artifacts, so an approval that expires/reaps without a final resume no longer loses everything streamed during the resumed segment. - request: carry `manualSkills`/`alwaysAppliedSkills` on the persisted user message so a resumed turn's reconstructed requestMessage keeps its skill pills instead of dropping them until a full reload. Deferred (narrow, no safe contained fix yet — see PR thread replies): - resume rebuild without `addedConvo` for a multi-conversation/added-agent pane - cross-replica re-prime of manually-selected (not model-invoked) skill files Tests: stale-agent createJob clearing (Redis integration), promptPrefix fingerprint match/mismatch (resume.spec.js + policy.spec.ts), re-pause content persistence (resume.spec.js). * fix(hitl): address Codex re-review (round 8) Five findings verified against the code before fixing; the headline is a durable- resume correctness fix (the fingerprint had surfaced it as a 403): - resume durability (the important one): persist the graph-determining request fields (endpoint, agent_id, model, spec, promptPrefix, ephemeralAgent) on the pending action as `resumeContext`, and REPLAY them onto the resume request via a router-level middleware that runs before buildEndpointOption. The client can't reconstruct the ephemeral-agent config after a reload/cross-session, so the round-6/7 fingerprint would 403 a valid durable resume — and even without it the rebuilt agent would lose its tools. Replaying server-side rebuilds the SAME graph regardless of client state (and a crafted resume can't swap it; the fingerprint still matches because the body is restored first). - RedisJobStore: also clear `isTemporary` on createJob (same class as agent_id): a prior temporary turn's flag would otherwise survive a reused conversation hash and a later non-temporary resume would save its response as temporary. - resume: persist `contextMeta` (context-window calibration) onto the saved response like BaseClient does, so the next turn can seed its pruner. - request: carry manualSkills/alwaysAppliedSkills into the onStart metadata update (not just the preliminary one it overwrites), so a resumed turn's requestMessage keeps its skill pills. Deferred (narrow — see thread reply): - saved-agent edited WHILE a run is paused: agent_id matches but the definition changed; needs an agent version/config hash, which is a larger change for a narrow window. Tests: resumeContext pick/apply + round-trip (policy.spec.ts), contextMeta + manualSkills-on-requestMessage (resume.spec.js), isTemporary clearing (Redis integration). * style(hitl): prettier line-wrap in policy.spec.ts (R8 lint fix) * fix(hitl): address Codex re-review (round 9) Five findings, all fixed (addedConvo — deferred in rounds 7/8 — is now trivial thanks to the round-8 replay): - replay addedConvo: add it to RESUME_CONTEXT_KEYS so the resume middleware restores the parallel/secondary-agent config from the paused request; the client can't reconstruct it, and it determines the rebuilt graph. - skill pills (the real fix this time): the round-8 onStart metadata write was overwritten by trackUserMessage (the authoritative userMessage writer). Carry manualSkills/alwaysAppliedSkills in the emitted `created` message and persist them in trackUserMessage; widen UserMessageMeta + SerializableJobData.userMessage. - execute-code files on resume: seed the paused user message's own files onto req.body.files before initializeClient — they're excluded from the parent-walk code-session rebuild, so an approved code/read-file tool would otherwise resume without them. - in-memory pending-action UI: route ApprovalEvents.ON_PENDING_ACTION in the resume replay/pending-event loops to applyPendingActionToMessages (mirror the live handler), so a pause that lands in the snapshot window still renders its approval controls instead of sitting paused with no UI. - abort isTemporary: the /chat/abort partial-save now sources isTemporary from the job metadata, not req.body (the stop button posts only conversationId), so aborting a paused temporary chat no longer persists an orphaned partial. Tests: addedConvo in pickResumeContext (policy.spec.ts), file-restore on resume (resume.spec.js), abort-from-job-isTemporary (abort.spec.js). * fix(hitl): address Codex re-review (round 10) — resume/expiry races Three concurrency/coherence findings, verified against the code before fixing: - expiry-sweep CAS scope: both stale-approval sweeps (GenerationJobManager expireStaleApprovals and the RedisJobStore requires_action cleanup) called expire()/transitionStatus WITHOUT the observed pendingAction.actionId, so the CAS only checked status===requires_action. Between the read and the CAS a user could resolve the observed action and the run re-pause on a FRESH action; the stale sweep would then abort that valid new pause. Now both pass the observed actionId as expectActionId, so the CAS only fires for the action read as stale (a re-paused action has a different id → no-op). - resume graph cache: resumeCompletion cached the rebuilt graph (created with messages:[]) via setGraph; RedisJobStore.getContentParts prefers a cached graph over reconstructing from the chunk log, so a same-replica reload/status poll mid-resume returned aggregatedContent missing the pre-pause content. Skip setGraph on resume so introspection falls back to the complete chunk reconstruction (setContentParts still seeds the in-memory store). - pending-action UI: applyPendingActionToMessages scheduled a SINGLE animation-frame retry then dropped the pending action; Recoil/React updates can take several frames under load, leaving a valid requires_action run with no approval controls. Retry across frames (bounded at 120) until the target message commits. Test: expire() with a mismatched expectedActionId no-ops while the matching id expires (pendingAction.spec.ts). * chore(deps): update @librechat/agents to version 3.2.53 and @langchain/langgraph to version 1.4.7 in package-lock.json and related package.json files * refactor(hitl): add resolveToolApprovalPolicy seam for layered policy Extract the single point where tool-approval policy is resolved for a turn (`resolveToolApprovalPolicy`) and route the run call site through it instead of reading `endpoints.agents.toolApproval` inline. Behaviour-preserving: only the `endpoint` layer is wired today, so the result is identical to reading the app policy directly. The `agent` and `skills` layers are reserved seams with documented precedence (endpoint owns the `enabled` kill switch; agent overrides mode/allow/deny/ask/reason; skills may only tighten), so future per-agent and per-skill policy plumbing lands in one function rather than at the `createRun` site. Adds focused unit tests. * fix(hitl): address Codex re-review (round 11) — resume hardening F1 (P2, security) — applyResumeContext now DELETES any RESUME_CONTEXT_KEY absent from the persisted context, so the resume body carries exactly the graph-determining fields the pause had. Previously only defined keys were overwritten, leaving a client-supplied `addedConvo` (which the request fingerprint does not cover) in place — a crafted resume could rebuild a single-agent checkpoint as a different multi-agent graph/tool set. F3 (P2) — the resume route ACKs (res.json) before initializeClient, so a post-ACK getMCPRequestContext(req, res) saw the response as finished and returned undefined, leaving the resumed run without its run-scoped MCP connection store (approved MCP / OAuth-overlay tools then ran without their request-scoped connections). Pre-seed the store with a null res + cleanupOnResponse:false before the ACK and tear it down in the finally, mirroring the normal stream path (request.js). userMCPAuthMap was already preserved separately, so credentials were not lost — only the connection store. Declined: the ApprovalContext NEW_CONVO guard (P2) is a false positive — the `created` SSE event updates the conversation atom before any pause renders, so the id is concrete by click time (details in the PR thread). Tests: policy.spec (absent-key delete) + resume.spec (MCP context pre-seed/cleanup order). * fix(hitl): address Codex re-review (round 12) — resume fidelity + multi-tool UI F4 (P2) — temporal prompt vars: resume rebuilt the agent without restoring req.conversationCreatedAt or req.body.timezone, so {{current_datetime}}-style vars compiled a different system prompt than the paused graph (resume wall-clock, unzoned). Add 'timezone' to RESUME_CONTEXT_KEYS (persisted at pause, replayed by the resume middleware) and restore conversationCreatedAt from the convo before initializeClient — mirroring the normal path's resolveConversationCreatedAt. F5 (P2) — multi-tool approval: applyPendingActionToMessages stopped retrying once ANY tool-call part was tagged, so siblings that rendered on later frames never got approval controls and the resume route 400'd the partial batch. Add countTaggedApprovalParts and keep the bounded RAF retry going until every action_request is tagged (ask_user_question unchanged — one synthetic part). F6 (P3) — Edit accepted `null`/`[]` (valid JSON, non-object), enabling Submit for a value the resume route rejects via findIncompleteDecisions. Mirror the server's plain-object check in the client (store + editIsValid) so Submit only enables for an accepted value. Tests: policy.spec (timezone round-trip), resume.spec (conversationCreatedAt restore), approval.spec (countTaggedApprovalParts). * fix(hitl): address Codex re-review (round 13) — recurse into subagent approvals F9 (P2) — a tool paused INSIDE a subagent has its tool_call_id in the parent subagent tool_call's nested `subagent_content`, not as a top-level message part. applyToolApproval and countTaggedApprovalParts only scanned top-level content, so the approval never attached and the round-12 retry loop counted 0 tagged parts and spun to its frame cap with no controls. Both now recurse into `subagent_content` (immutably, so React refs update): the nested call gets tagged and is counted, so the retry terminates. Added approval.spec cases for the nested tag + count. Note: surfacing the interactive approve/reject controls inside the subagent view is a deliberate follow-up — ToolApproval -> useResumeSubmit -> useChatContext crashes when rendered in the portaled subagent dialog (outside the chat/approval providers), so that needs the controls scoped to the in-provider inline render (or the dialog wrapped with the providers). This commit fixes the data/traversal layer only. F7 (discovered-tool history on resume) and F8 (redis chunk TTL pause race) were verified false positives — see the PR threads. * fix(hitl): address Codex re-review (round 14) — resume fidelity + expiry relay F13 (P2) — manualSkills are graph-determining (skill allowed-tools union into the tool set before tools load) but weren't replayed, so a reload lost the skill tools and a crafted resume could inject a different skill past the fingerprint. Add 'manualSkills' to RESUME_CONTEXT_KEYS (same replay-only pattern as timezone/ addedConvo; the delete-absent half blocks injection). Not alwaysAppliedSkills — that's resolved server-side from the DB, not req.body. F12 (P2) — the resume final SSE built requestMessage from job.metadata.userMessage (persisted without files), so attachments vanished from the user bubble on resume. Spread the already-restored req.body.files onto it, matching the normal path. F11 (P2) — multi-replica approval expiry: RedisJobStore.cleanupRequiresActionIndex on another replica can win the requires_action->aborted CAS (it sets the hash error but has no event transport), and the local sweep then skips because the job is no longer requires_action, so a client subscribed here never gets the terminal error until the reap path. expireStaleApprovals now relays APPROVAL_EXPIRED_ERROR for a locally-subscribed job already aborted FOR approval expiry (error-string gated, idempotent via the errorEvent flag). emitError already publishes cross-replica. Tests: policy.spec (manualSkills round-trip + inject-drop), resume.spec (final requestMessage carries restored files). * fix(hitl): render approval controls for subagent-nested tool pauses (F10) Round-13 made applyToolApproval/countTaggedApprovalParts recurse into subagent_content (data), but SubagentDialogPart rendered nested TOOL_CALL parts with <ToolCall> only and never mounted <ToolApproval>, so a tool paused inside a subagent showed no controls and the run was unresolvable. Render <ToolApproval> in SubagentDialogPart's TOOL_CALL branch when the nested tool_call carries an approval and isn't yet resolved, mirroring the top-level Part.tsx render. The subagent dialog portals (OGDialog → ReactDOM.createPortal), but React context flows through the React tree, not the DOM tree, so ToolApproval resolves ApprovalProvider/ChatContext and the controls work + submit. Also harden useResumeSubmit: read ChatContext via useContext (non-throwing) instead of the throwing useChatContext wrapper, so the cards never crash when rendered outside a ChatContext.Provider (e.g. a search/citation render that passes chat context as a prop) — they degrade to inert (buildResumeFields returns null). * style(hitl): re-sort run.ts imports after dev rebase * fix(hitl): address Codex re-review (round 15) — resume content fidelity F14 (P2) — hide_sequential_outputs was applied in chatCompletion before saving/emitting content but not on resume, so a sequential-agent chain that pauses for HITL and resumes persisted/emitted intermediate outputs the setting is meant to hide. Extracted the filter into applyHideSequentialOutputsFilter() and call it from both chatCompletion and resumeCompletion (after handleRunInterrupt, covering the finalize + re-pause reads of client.contentParts). F16 (P2) — on a reloaded HITL pause, the DB already holds the paused user row + partial assistant row; useResumeOnLoad fed those as submission.messages, then finalHandler/createdHandler appended the same pair via requestMessage/responseMessage, duplicating the turn (buildTree doesn't dedupe children by messageId). buildSubmission- FromResumeState now strips the paused user/response rows (by messageId, incl. the padded/unpadded response id) from submission.messages — they're re-supplied by the placeholders + final event. Frontend-only; live (non-reload) pause path untouched. Deferred: F15 (collapsed-card subagent approval registration/visibility) — see thread. Tests: client.test (filter keeps last + tool_call parts / no-op when off), useResumeOnLoad.spec (paused pair stripped from submission.messages). * fix(hitl): address Codex re-review (round 16) — chunk TTL, slot, job replacement F17 (P2) — chunk-stream TTL on pause-before-chunk. CHUNK_APPEND_LUA derived its ceiling only from the chunk key's current TTL, so when the chunks key didn't exist at pause (fire-and-forget append in flight, or an ask-user pause before any chunk), the on_pending_action append created the stream with only the 20m running TTL while the approval window is 24h — content evicted before resume. The Lua now also reads the job key (KEYS[2]); when status == requires_action it takes max(running, TTL(jobKey)) (the approval window transitionStatus set), else the running TTL. Extend-only preserved; gated on paused status so normal runs never inflate. Both keys share {streamId} (cluster-safe). F19 (P2) — with LIMIT_CONCURRENT_MESSAGES, the approval prompt was emitted before the original request released its slot, so a fast Approve got /resume 429'd. handleRunInterrupt now releases the slot (idempotent via pendingRequestReleased) right after the pause, before the prompt; the request.js pause branch and resume.js finally only release if it didn't (no double-release). F20 (P2) — finalizeResumedTurn never checked the job wasn't replaced before emitDone/ completeJob/saveMessage, so a stale resume could clobber a newer turn that reused the conversationId. Added the createdAt guard the normal request path uses (skip finalization when the live job's createdAt != the paused job's). Deferred: F18 (subagent_content not reconstructed on Redis resume) — joins the subagent cluster (F15). See thread. Tests: RedisJobStore integration (pause-before-chunk gets approval TTL; running stays short), resume.spec (skip finalization on replacement; no double slot release on re-pause). * 🛡️ fix: Guard HITL terminal side-effects against job replacement Jobs are keyed by streamId == conversationId, so a new request REPLACES the running one on the same conversation. The replaced generation's tail must not clobber the live generation's state. Each path now re-reads the live job and compares createdAt against the generation's captured identity before acting. - Thread the generation's createdAt onto the client (request.js + resume.js) as client.jobCreatedAt — the identity every guard compares against. - handleRunInterrupt: skip approvals.pause when this run is no longer the live job, so a stale interrupt can't flip the NEWER job to requires_action. - chatCompletion finally: skip the checkpoint prune when replaced, so an older run's late finally can't delete the newer run's resume checkpoint. - resume catch-path: gate emitError/completeJob/prune behind a stillLive check (fail-open if the read throws), mirroring finalizeResumedTurn's success guard. - Persist the turn's uploaded files on job.metadata.userMessage (authoritative trackUserMessage writer) and prefer them on resume over the user DB row, whose save can still be racing a fast /resume. Tests: 13 guard-predicate cases in jobReplacement.spec.js. * 🔁 fix: Harden HITL resume — ownership re-check, file seeding, deferred-tool replay Three follow-ups to the round-17 job-replacement guards (Codex review 4594099963): - G1 (resume.js): the success-path ownership guard runs at the START of finalizeResumedTurn, but saveMessage + first-turn title generation await long enough for a new request to replace the job on the same conversationId. Re-read the live job immediately before emitDone/completeJob/prune so the terminal writes can't tear down the REPLACEMENT job — mirrors the catch-path guard. - G2 (request.js): onStart's metadata/chunk writes that persist the turn's files are fire-and-forget, so a fast approval could read job.metadata.userMessage before files landed. Seed files into getPreliminaryUserMessage instead — that write is AWAITED before the run starts, so files are durable before any interrupt can emit. - G3 (run.ts + client.js + resume.js + IJobStore.ts): the resumed graph is rebuilt with messages: [], so createRun's tool_search-discovery scan finds nothing. A deferred tool discovered earlier in the turn (and targeted by the paused call) was therefore absent from the rebuilt schema-only toolMap — resume would throw "unknown tool" (no loadRuntimeTools fallback is wired). Capture discovered tool names at pause via extractDiscoveredToolsFromHistory(run.getRunMessages()), persist them on job.metadata.discoveredTools, and replay them into createRun's new discoveredToolNames input (merged with message-extracted names, gated on hasAnyDeferredTools — inert otherwise). A new createRun test proves the deferred tool is promoted with the replay and absent without it (reproducing the bug). Tests: real createRun deferred-replay suite (run-summarization.test.ts) + G1/G2/G3 guard predicates (jobReplacement.spec.js). Full suite green. * 🔒 fix: Close HITL resume metadata + file-substitution + pause-race gaps Four findings on the round-18 commit (Codex review 4594430222): - H1 (P1, regression in round-18 G3): the discoveredTools captured at pause never reached resume — three metadata allowlists dropped it: GenerationJobManager .updateMetadata, RedisJobStore.deserializeJob, and buildJobFacade (plus the GenerationJobMetadata type). Added discoveredTools to all four, so the deferred-tool replay actually works end-to-end (in-memory store already kept it via Object.assign). - H2 (P2, security): /resume honored a client-supplied `files` array, letting a crafted client resume an approved code/read-file tool against a DIFFERENT file set than the one approved (files aren't in the resume fingerprint/context). Resume now ALWAYS sources files from the paused job (metadata → DB row), clearing any client-supplied set. - H3 (P2, ephemeral fidelity): non-default model parameters (temperature, max tokens, custom endpoint params) were lost on resume — ephemeral agents derive them from the request body, which the resume payload omits. Capture the resolved model_parameters in resumeContext at pause and replay them onto the body on resume (excluding `model`, which is replayed via the fingerprinted RESUME_CONTEXT_KEYS path). Saved agents already source these from the DB. - H4 (P2, Redis race): a pause landing between the resume snapshot and the Pub/Sub subscription reached neither resumeState.pendingAction nor (Redis) pendingEvents, and approval events aren't persisted to replayEvents — the client attached to a paused job with no approval UI. subscribeWithResume now re-reads the live job AFTER subscribing and surfaces the pending action if the snapshot missed it (live read, no staleness). Tests: discoveredTools metadata round-trip + subscribeWithResume re-read (pendingAction .spec.ts); client-file substitution rejection (resume.spec.js); model-parameter replay predicate (jobReplacement.spec.js). * 🧹 fix: Clear stale discovered tools, release slot on claim error, extend run-step TTL Three follow-ups on the round-19 commit (Codex review 4594783691): - I1 (P2): the round-19 discoveredTools field wasn't cleared on Redis streamId reuse. HSET only overwrites listed fields and handleRunInterrupt only writes discoveredTools when THIS turn discovers a deferred tool — so a replacement turn that pauses without its own discovery inherited the prior run's tool names and force-loaded undiscovered deferred tools on resume. Added discoveredTools to createJob's staleHitlFields HDEL list (the in-memory store already builds a fresh object, so it was Redis-only). - I2 (P2): with LIMIT_CONCURRENT_MESSAGES, approvals.resolve runs after the slot increment but before the run's try/finally, so a store/Redis error there leaked the slot until the counter TTL expired (spurious 429s on retry of the still-paused approval). Wrapped the claim in try/catch that decrements the slot and returns 500. - I3 (P3): saveRunSteps did SET ... EX running unconditionally, resetting the run-steps key to the 20-min running TTL even while the job is paused for the longer approval window — a reload after that window lost the tool timeline. Now uses a paused-window TTL script mirroring the chunk-stream no-shrink behavior (extends to the approval window when the job hash is requires_action). Also fixes a latent strict-tsc cast error in the round-19 pendingAction test. Tests: claim-throws-releases-slot (resume.spec.js); discoveredTools cleared on reuse + saveRunSteps preserves the paused TTL (RedisJobStore integration, USE_REDIS). * 🛡️ fix: Guard fast-resume save race, gate HITL to resumable routes, expire on stale submit Three findings on the round-20 commit (Codex review 4595045652): - J2 (P1): a fast /resume can claim + finalize the COMPLETED response while the original request's pause branch is still awaiting `response.databasePromise`; the later unfinished-save then overwrites the completed content. Re-check the job is still paused on THIS generation's action (a claim leaves requires_action; a replacement bumps createdAt) before marking the row unfinished; fail open on a read error. - J3 (P1): the tool-approval wiring (humanInTheLoop + PreToolUse hook + checkpointer) was applied to EVERY createRun caller when toolApproval.enabled, but the OpenAI-compatible and Responses controllers never inspect run.getInterrupt() or persist a pending action — an approval-gated tool would pause there with no approval surface or resume endpoint and the route would emit a normal final response / [DONE] with the tool call dangling. Gate the wiring on a new createRun `hitlCapable` flag, set only by AgentClient (chat + resume). - J4 (P2): a stale-action 409 on submit returned without driving expiry, leaving the job requires_action with a dead action until the periodic sweeper ran — any attached SSE client got no terminal event and the stream appeared to hang. Extracted GenerationJobManager .expireApproval(streamId, actionId) (expire CAS + terminal SSE, shared with the sweeper) and call it from the resume route when the observed action is stale. J1 (nested subagent approval controls not mounting while the details dialog is closed) is a valid frontend issue in the deferred subagent-HITL path — tracked separately (replied on the thread) since the fix touches the shared dialog primitive and needs UI verification. Tests: HITL-gate both directions (run-summarization.test.ts); expire-on-stale-submit (resume.spec.js); fast-resume unfinished-save guard predicate (jobReplacement.spec.js). * 💄 style: Wrap captureAgents signature to satisfy prettier (CI lint)	2026-06-29 16:56:41 -04:00

Danny Avila	d9a76fca90	🧠 feat: Configurable Reasoning Replay for Custom Endpoints (#13921) ... * 🧠 feat: Configurable Reasoning Replay for Custom Endpoints Adds customParams.includeReasoningContent so OpenAI-compatible custom endpoints (e.g. Xiaomi MiMo, Kimi) can replay reasoning_content on tool-call turns natively, without impersonating the moonshot provider. * 🔁 feat: Replay reasoning_content across turns for opted-in custom endpoints Extends the DeepSeek reasoning-content format spoof to honor customParams.includeReasoningContent, so custom OpenAI-compatible endpoints (Xiaomi MiMo, Kimi) reconstruct reasoning_content from persisted history on later turns, matching DeepSeek thinking-mode parity. Adds shouldReplayReasoningContent predicate (tested) and surfaces the flag on the initialized agent. * 🪢 refactor: Split within-run vs cross-turn reasoning replay flags moonshot only replays reasoning_content within a run's tool calls, not across turns. Decouples the two: includeReasoningContent = within-run replay (exact moonshot parity), new includeReasoningHistory = cross-turn reconstruction from persisted history (implies includeReasoningContent, since reconstruction is a no-op without the within-run replay flag). * 🩹 fix: Apply reasoning replay across all param-format branches Move the within-run includeReasoningContent application out of the OpenAI-only branch in getOpenAIConfig to after the branch dispatch, so custom endpoints using anthropic/google defaultParamsEndpoint gateway modes also honor includeReasoningContent/includeReasoningHistory. Addresses Codex finding. * chore: Update @librechat/agents to v3.2.46 * 🧽 refactor: De-spoof reasoning replay via explicit preserveReasoningContent Now that @librechat/agents 3.2.46 exposes an explicit preserveReasoningContent option on formatAgentMessages, pass it directly instead of impersonating provider: deepseek. Behavior is unchanged (shouldReplayReasoningContent still gates DeepSeek + the custom includeReasoningHistory flag); also corrects the comment to reference includeReasoningHistory. * 🌳 fix: Walk subagents in the reasoning-history replay gate The gate only checked the primary agent and top-level handoff/parallel configs, so an opted-in custom endpoint used solely as a nested subagent had its persisted reasoning dropped on later turns. New exported anyAgentReplaysReasoningContent walks subagentAgentConfigs (cycle-safe, mirrors anyAgentHasCodeEnv); client.js uses it. Addresses Codex finding.	2026-06-23 21:08:47 -04:00

Danny Avila	68d142d0e9	🦜 refactor: Use path for Read/Write/Edit/Create File Tools (#13834) ... * 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.)	2026-06-18 14:44:51 -04:00

Danny Avila	c04bddd304	🪵 refactor: Bound Log Traversal And Remove Legacy api/config Logger (#13813) ... * 🛡️ fix: Bound object-traverse against DAG fan-out and shared refs Detect cycles via the ancestor chain (so shared, non-circular references in sibling branches / DAGs are traversed correctly) and add defensive maxNodes (100k) / maxDepth (100) caps. The removed global visited set was implicitly bounding work at O(distinct nodes); ancestor-chain-only detection is O(root-to-node paths), exponential on DAGs (a depth-24 diamond went from 26 to 50M visits / 1.6s of synchronous work). The caps bound it to ~9ms while leaving normal traversal untouched. Adds a spec covering shared refs, cycles, DAGs, and both bounds. The lone consumer, debugTraverse, inherits the defaults with no change. * 🪵 refactor: Remove legacy api/config logger duplicate The api/config winston logger was a stale parallel implementation of the canonical @librechat/data-schemas logger, with unbounded redaction (regex-only redactFormat, npm traverse-based debugTraverse). Its winston instance and the logger export from api/config/index.js had zero consumers — every ~/config importer uses the MCP/flow-manager exports. The only live tie was ToolService's use of redactMessage. Re-export redactMessage from @librechat/data-schemas (behaviorally identical, a superset of the regex set), point ToolService at it, delete api/config/winston.js and api/config/parsers.js, drop the dead logger export, and remove the orphaned ~/config/parsers mock from the global test setup. * 🧹 chore: Drop orphaned traverse dep and stale legacy logger tests Deleting api/config/{winston,parsers}.js left the npm 'traverse' package unused in api/package.json (flagged by the detect-unused-packages CI check) and orphaned two tests that imported the deleted modules. Remove the traverse dependency (sync package-lock), and delete api/config/__tests__/{parsers,logToFile}.spec.js — the canonical logger's behavior is covered by packages/data-schemas/src/config/parsers.spec.ts. * 🩹 fix: Make object-traverse caps bound work and survive update() Address Codex review: (1) break the child loops as soon as the node budget is spent and iterate objects via for...in instead of materializing Object.entries/Object.keys, so maxNodes actually bounds work for wide arrays/objects; (2) detect ancestor cycles against an immutable original-node stack rather than context.node, which a callback's update() can reassign (the debug formatter rewrites array nodes in place). Adds tests for the wide-array bound and the update()-cycle case. * 🎚️ fix: Tighten object-traverse defaults to a ~1ms log budget Lower maxNodes 100000 -> 2500 and maxDepth 100 -> 5. Measured cost is ~140ns/node with the debug formatter callback, so 2500 nodes keeps a single log under ~1ms even on slower prod hardware; real log objects are ~25-30 nodes at depth 3-4, leaving ample headroom. maxNodes is the fan-out/cost lever; maxDepth bounds recursion and output readability (depth-5 covers typical logs, deeper renders compactly).	2026-06-17 12:31:32 -04:00
Danny Avila	fdc7e64bb7	🪙 feat: SDK-Aligned Context-Usage Projection (gauge for window-switch & snapshot-less branches) (#13801) ... * 🪙 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.

Danny Avila	98755d86c8	📦 chore: Declare runtime deps externalized by tsdown in @librechat/api (#13600) ... 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`.	2026-06-08 13:18:04 -04:00
