🗄️ fix: Return Cached Transaction-Support Value on Cache Hit (#13999)
getTransactionSupport initialized transactionsSupported to false and only assigned it on a cache miss (transactionSupportCache === null), so on a cache hit it returned false regardless of the cached value. After the first bulkUpdateResourcePermissions call populated the cache with true, every later call reported false and the bulk permission writes silently stopped running inside a MongoDB transaction, losing atomicity. Return the cached boolean on a cache hit; the cache-miss path still probes via supportsTransactions. Adds a regression test. |

🧯 fix: Harden Principals Cache Invalidation and Lock-Wait Paths (#14120)
* 🧯 fix: Harden Principals Cache Invalidation and Lock-Wait Paths Follow-up hardening for the group-membership principals cache: - Coalesce deferred transactional invalidations into one session `ended` listener so many membership writes in a transaction cannot trip the emitter's max-listeners warning - Re-attempt the build lock inside the lock-wait poll so readers take over when the holder skips its write (invalidated away, failed, or crashed) instead of stalling for the full wait budget - Read cache builds from the primary so secondaryPreferred deployments cannot pin a lagging secondary's pre-mutation memberships for the TTL - Decouple the delayed stale-rewrite eviction pass from build locking via a crossProcess store marker, so USER_PRINCIPALS_LOCK_TTL_MS=0 disables locking only - Treat aggregation-pipeline bulk updates touching memberIds as indeterminate (namespace clear) instead of silently skipping invalidation * ⏲️ fix: Floor the Stale-Eviction Delay for Lockless Cache Builds The second invalidation pass ran at only 500ms when build locking is disabled (USER_PRINCIPALS_LOCK_TTL_MS=0), so a cross-container build slower than that could still re-cache revoked memberships until the TTL. The store now supplies an explicit staleEvictionDelayMs (lock wait plus one build round-trip, floored at 3s), keeping the default locked budget unchanged. |

🧰 feat: Redesign Agent Builder with Unified Tools Marketplace, Skills & Orchestration (#13952)
* feat: redesign the agent builder tools, skills, and advanced panels
Replace the stacked capability/MCP/skill/tool/action form sections with a unified tools marketplace, per-item configuration dialogs, and a consolidated Advanced panel.
- unified tools marketplace (catalog, sidebar, polymorphic cards/rows) covering built-in capabilities, plugins, MCP servers, and actions, each with a detail/config dialog
- dedicated Skills picker and a Tools section with selected-item summaries and empty states
- redesigned action editor and authentication dialog (method cards, segmented controls)
- rebuilt Advanced panel: orchestration hub (subagents, handoffs, chain), max steps, skills kill-switch, copyable agent id
- restyled version history (timeline, tool/capability counts, in-app restore confirmation)
- shared component updates (Radio, Input/Textarea, dropdown z-index, dialog primitives) and keyboard-only focus rings via useInputModality
- format-hint placeholders for tool credential fields
- sanitize numeric parameter inputs to prevent comma truncation
* feat: refine agent builder tools, actions, and MCP sections
* feat: restore Memory capability toggle in agent builder tools catalog
* feat: refine agent tools picker (skills, MCP connect/OAuth, web search)
- Skills picker: per-card visibility (public) and shared-author badges,
category filtering, and an in-place Create skill flow that auto-attaches
the new skill without leaving the builder
- MCP: inline Connect button in the first dialog plus a dedicated OAuth
dialog (continue, copyable URL, QR code) shown only when OAuth is required
- Web search: auth-aware affordance, settings cog when user-provided and an
info icon when system-defined
- Remove orphaned com_ui_unavailable/com_ui_initializing keys and the dead
Tools/MCPToolItem component
* refactor: streamline MCP OAuth dialog
- Remove the Cancel button (the flow auto-closes on connect / times out)
- Show the URL in a read-only single-line scrollable input (cursor moves
through it, not fully visible) with the shared CopyButton's smooth
Copy/Check icon swap, matching the OAuth callback-URL field
- Put the primary Continue with OAuth action (icon trailing) and an
icon-only QR toggle together in a row at the bottom, below the URL
- The QR reveals between the description and the URL with a smooth height
animation (grid-rows 0fr to 1fr, matching MCPToolItem's reveal)
* feat: smoothly collapse MCP connect button once connected
* feat: cross-fade MCP tools between loading, list, and empty states
* feat: show MCP server icon in OAuth dialog title
* fix: vertically center OAuth dialog title against the MCP icon
* feat: smoothly animate auth field changes in the MCP server dialog
* feat: match Code Interpreter file upload to the File Search dropzone
Swap Code Interpreter's thin btn-neutral bar for the same dashed dropzone
(DropzoneContent + dropzoneClassName) File Search already uses, so the two
capabilities' upload UIs are consistent.
* feat: show a saving spinner and allow cancelling credential edits
Drive the tool credential Save button from the real mutation state so it
shows a spinner while the request is in flight, and add a Cancel button
when re-editing already-saved credentials so the edit can be dismissed.
* feat: make the skills create button a compact icon button
* fix: restore MCP attach semantics and confirmations in the tools marketplace
Connecting an MCP server from the item dialog now enables all of its tools
once the connection settles, deselect-all keeps the server attached via its
placeholder token instead of detaching it, adding a server writes the token
so a zero-tool attachment survives a save, and removing a server from the
tools list asks for confirmation again. Consume-only servers are excluded
from the catalog, matching the old select dialog.
Also share the catalog/selection pipeline between ToolsSection and the
marketplace through useAgentItems, hoist NEW_ACTION_ID next to ActionItem,
drop unused status/view union members and stale TranslationKeys casts,
document the phase-2 Favorites/Made-by-you views, fix the needs-setup dot
semantics and card focus suppression, remove the redundant close button in
CreateSkillDialog, move useInputModality into @librechat/client so external
consumers can mount it, and delete dead files and orphaned translation keys.
* fix: scope tooltip elevation to dialogs and restore dialog close button size
Tooltips go back to z-150 globally; inside a dialog they now borrow the
depth-aware popover z-index so they still clear nested dialogs (the Tool
Library item dialog) without outranking freshly opened modals everywhere
else. The default dialog close icon returns to its original size, and the
lc-field pointer-focus suppression ships with the package next to Input and
Textarea so external consumers get the whole mechanism from @librechat/client.
* feat: add favorites for marketplace tools, MCP servers, and skills
Reintroduce the favorite star from the old skill picker, generalized to
every marketplace item kind except per-agent actions. Cards in the Tool
Library and Skills dialogs get a hover-revealed star (always visible once
favorited), and the existing Favorites views in both dialogs now filter to
starred items.
Favorites persist in a dedicated ToolFavorite collection, one document per
(user, itemType, itemId) with a unique compound index, exposed through
atomic per-item PUT/DELETE endpoints under /api/user/settings/favorites/
tools. Per-item writes are idempotent and race-free across tabs/devices
(the unique index backstops concurrent toggles), reads are a single
index-backed query capped at 100 favorites per user, and the client keeps
React Query as the source of truth with optimistic updates. Handlers live
in @librechat/api with a thin route wrapper; methods follow the
data-schemas factory pattern with tenant isolation.
The favorites filter now matches on compound kind:id keys instead of bare
ids, closing a cross-kind collision where a tool and a skill sharing an id
would both match. The skill-favorites data-service stubs and the reserved
TUserFavorite.skillId field are replaced by the new tool-favorites service.
* feat: anchor the favorite star at the card's right edge
Swap the ToolCard action-bar order so the star sits rightmost with the
configure/info icon to its left. Every card can be favorited but only some
are configurable, so anchoring the star keeps it in a consistent position
across the grid.
* chore: remove translation keys orphaned by the tool library redesign
* fix: gate marketplace creation entries and resolve off-page selected skills
The Create New menu exposed MCP server creation to users without the
MCP_SERVERS create permission and action creation on deployments with the
actions capability disabled; both entries are now gated like their
pre-redesign counterparts, and the button hides when neither applies.
Selected skills missing from the first catalog page (limit 100) were
dropped from the Skills section entirely, leaving them impossible to
inspect or remove. useResolvedSkills restores the per-id lookup: off-page
skills are fetched individually and confirmed misses (deleted or no longer
shared) stay visible under an Unavailable skill placeholder so the stale
allowlist entry remains removable.
* fix: refetch favorites when toggled before the list loads, lint fixes
An optimistic favorite written over an unpopulated cache seeded the list
with only the toggled item, and cancelQueries killed the initial fetch
that would have corrected it, hiding existing favorites until reload. The
optimistic write now only applies over known data; otherwise onSettled
invalidates so the authoritative list is refetched.
Also unnest the version date-label ternary and drop an unused form watch
flagged by CI.
* fix: sync skills_enabled with selection edits and hydrate agent file entries
skills_enabled is the master opt-in for the skill allowlist, and an empty
allowlist with the flag on means the full accessible catalog. Selection
edits now sync the flag on empty/non-empty transitions via a shared
skillsEnabledTransition helper: picking the first skill enables it so the
choice takes effect on save, and removing the last one disables it so the
agent doesn't silently escalate to every skill. Mid-selection edits leave
the flag alone, preserving the Advanced kill switch's
disable-without-clearing behavior.
Agents loaded from the API carry only tool_resources.*.file_ids; the
client-only context/knowledge/code file entry arrays were read directly,
so existing attachments rendered as empty and could not be removed. A new
useAgentFileEntries hook restores the legacy derivation (agent files query
merged into the file map via processAgentOption) and now feeds AgentConfig,
the item dialog, and the selected-items pipeline.
* fix: hide plugin tools from the marketplace when the tools capability is off
buildCatalog gated built-ins, MCP, and skills on their capabilities and
permissions but pushed regular plugin tools unconditionally, so deployments
that removed the tools capability still offered attachable tool cards in
the marketplace. The loop now requires AgentCapabilities.tools, matching
the old Add Tools gate.
* fix: strip legacy MCP tokens on removal, guard action creation, model button spacing
MCP selection accepts every historical token format (server placeholder,
raw server name, mcp_-prefixed, and per-tool ids in prefix/suffix shapes)
but removal only filtered the new placeholder plus the server's current
tool ids, so a legacy token left the server permanently selected and its
tools still expanded after save. Selection and removal now share a
matchesMcpServer predicate.
Creating an action from the marketplace on an unsaved agent opened an
editor whose save was guaranteed to fail; it now surfaces the existing
save-the-agent-first error, matching the action-removal guard.
The model picker button keeps its tight px-1 with a provider icon but gets
px-3 in the empty Select-a-model state so the placeholder is not flush
against the border.
* fix: strip legacy prefix MCP tokens in useRemoveMCPTool
The hook only filtered the raw server name and suffix-delimiter tokens,
so confirming removal in the selected-tools section left persisted
prefix-format tokens (mcp_<server>, mcp_<server>_<tool>) in the form and
the row reappeared as selected. It now shares the matchesMcpServer
predicate with the selection logic so removal can never lag selection.
* fix: exact MCP token matching and keep errored skill lookups removable
The mcp_<server>_ prefix clause in matchesMcpServer was invented by the
redesign, not a persisted format (mcp_prefix is only ever used as the
exact mcp_<serverName> pluginKey), and it claimed longer server names
sharing a prefix: with servers github and github_extra, removing github
also stripped github_extra's tokens. The predicate now only matches exact
or delimiter-bounded shapes.
An off-page selected skill whose per-id lookup failed with a transient
error (retry disabled) vanished from the selected list until remount. Any
settled lookup failure now keeps the placeholder entry so the allowlist id
stays visible and removable; only in-flight lookups are briefly hidden.
* fix: route file-backed built-in removal to the file manager
Code Interpreter and File Search stay selected while they hold code_files
or knowledge_files, so removing them by flipping the capability flag left
the row visible and unremovable. Their removal now opens the config dialog
where the files are managed, mirroring the file-only context built-in;
with no files attached the flag still toggles off for a clean removal.
* fix: preserve negative values in numeric parameter inputs
sanitizeIntegerInput stripped every non-digit, so typing -1 in a numeric
parameter field became 1. That broke Google thinkingBudget, where -1 is
the dynamic/auto-thinking sentinel (range min is -1): users could no
longer select auto and risked sending a one-token budget. The sanitizer
now takes an opt-in allowNegative flag that keeps a single leading minus,
and DynamicInput passes it when the field's range permits negatives.
Thousands-separator cleanup is unchanged for all other fields.
* fix: keep in-progress negative numeric input and localize the actions heading
Typing a leading minus in a negative-capable numeric parameter (Google
thinkingBudget) sanitized to a lone '-', which was then coerced by
Number('-') to NaN, so the sign could not be typed before the digits. The
lone '-' is now stored as a string until a digit resolves it to a number,
matching how the empty-string case is already handled.
The agent builder actions panel heading hard-coded 'Add'/'Edit actions';
it now uses com_assistants_add_actions and a restored
com_assistants_edit_actions key so non-English locales translate it.
* chore: fix import order drift flagged by CI
* fix: treat pending web-search auth verification as needs_setup
While useVerifyAgentToolAuth is still loading, data is undefined so
web_search was not marked needs_setup, and the marketplace card takes the
direct-enable path only when status is not needs_setup. On a slow
connection a click before the response arrived enabled web_search without
collecting the required user-provided key. The auth map now flags
web_search needs_setup while the query is loading, routing the click to
the config dialog; once verification resolves, a system-defined deployment
or a satisfied key clears the flag for a direct toggle.
* test: update agent builder e2e selectors

🧹 feat: Eager HITL Checkpoint Cleanup (Expiry + Deletion) & Full-Wiring E2E (#14123)
* feat: eager HITL checkpoint cleanup on expiry + deletion, full-wiring e2e Follow-up to the lazy checkpointer (#14024): two paths still left a paused run's durable checkpoint to the 24h Mongo TTL, and no test exercised the whole HITL seam with real components. 1. Approval expiry: GenerationJobManager.setApprovalExpiredHandler(fn) — a non-destructive host hook fired after expireApproval's CAS succeeds (periodic sweeper AND stale-submit path), safe on startups that run constructor defaults. Both startups (index.js configureGenerationStreams, experimental.js) register a handler that prunes the checkpoint, resolving config lazily per expiry (streamId === conversationId === thread_id). 2. Conversation deletion: deleteConvos now returns the deleted conversationIds; the three deletion paths (DELETE /convos, DELETE /convos/all, account deletion) prune them via the new bulk deleteAgentCheckpoints (one $in deleteMany per collection). The delete routes gain configMiddleware for the checkpointer config. 3. Full-wiring e2e (hitlCheckpoint.e2e.spec.js): real SDK Run driven by FakeChatModel calling a gated tool, real PreToolUse/humanInTheLoop wiring, real LazyMongoSaver over mongodb-memory-server, real GenerationJobManager, real /resume controller via supertest. Asserts: clean turn persists nothing; error turn persists nothing; pause -> HTTP approve -> gated tool executes exactly once -> finalize prunes the checkpoint; expiry prunes the abandoned pause eagerly. Tests: 3 handler unit tests (pendingAction.spec), 2 bulk-prune integration tests (checkpointer.integration.spec), convos route + deleteUser specs updated, 4 e2e scenarios. 207 tests green across changed areas. * fix: tenant-scoped expiry prune, store-won expiry relay, resilient deleteConvos ids Codex round 1 on #14123 — all three valid: 1. The approval-expired handler now receives the expired JOB so both startups resolve config in the paused job's tenant/user scope (getAppConfig({userId, tenantId})) — a tenant checkpointer override no longer sends the prune to the base config's collections. expireApproval fetches the job best-effort. 2. Multi-replica: when RedisJobStore.cleanupRequiresActionIndex wins the expiry CAS on another replica, this replica's sweeper relay branch now runs the approval-expired cleanup too (prune is idempotent) — store-driven expiry no longer bypasses the hook. 3. deleteConvos: post-delete cleanup (deleteMessages, project stats refresh) is now best-effort — the conversations are already gone, so throwing hid the deletion and dropped the conversationIds the checkpoint prune needs, unrecoverable on retry. Updated the existing tag-decrement-on-failure test to the new contract (ids still returned). Tests: handler-receives-job, store-won relay path, ids-survive-cleanup-failure. 134 tests green across changed suites. * fix: relay cleanup independent of cached errorEvent; enter tenant ALS context Codex round 2 on #14123: 1. The sweeper's relay branch gated BOTH the terminal-error emit and the new checkpoint cleanup on !runtime.errorEvent — but a reconnect seeds errorEvent from the aborted job (runtime-state creation), which then suppressed the cleanup entirely. The emit stays gated; the idempotent cleanup now runs independent of the cached error, once per runtime lifetime (approvalCleanupRan flag — the aborted job is swept repeatedly). 2. Passing userId/tenantId to getAppConfig only keys the config cache; the Config query is ALS-scoped by the tenant-isolation plugin. Both startup handlers now ENTER the paused job's tenant context via tenantStorage.run before resolving config + pruning, so a tenant checkpointer override is honored in strict and non-strict modes. Tests: relay-cleanup-with-cached-error (reconnect simulation), repeated sweeps run the cleanup once. 27+4 green. * fix: dedup expiry cleanup across winner and relay paths Codex round 3 (P3): expireApproval ran the handler without marking the runtime's approvalCleanupRan flag, so the next sweep's relay branch (the aborted job outlives expiry for the completed-job TTL) ran the cleanup a second time. The dedup now lives inside runApprovalExpiredHandler — the single choke point both paths call — set-before-run, once per runtime lifetime. Test: local expiry followed by a sweep fires the handler once. |

⚡ perf: Persist HITL checkpoints only on pause (lazy checkpointer) (#14024)
* ⚡ feat: Persist HITL checkpoints only on pause (skip clean-exit writes) With `durability: 'exit'` (set by the SDK whenever a checkpointer is active) LangGraph persists ONE checkpoint at the exit boundary on EVERY run — paused or not. So a non-paused HITL turn writes a dead checkpoint whose only fate is to be pruned by deleteAgentCheckpoint: pure write+delete churn on the common path, given HITL only ever resumes an *interrupt* checkpoint. `InterruptOnlyMongoSaver` (a MongoDBSaver subclass) persists only interrupt checkpoints and discards clean-exit ones, so a non-paused turn writes nothing. How it tells them apart (verified empirically against @langchain/langgraph, not docs): when a run interrupts, the runner calls `putWrites` with the `INTERRUPT` ("__interrupt__") channel for the checkpoint it's about to create, and that write's `config.checkpoint_id` equals the `checkpoint.id` of the `put` that immediately follows. A clean exit calls `put` with no preceding interrupt `putWrites`. So we record the checkpoint id of any interrupt `putWrites` and persist a `put` only when its `checkpoint.id` was so marked. Keying on the globally-unique checkpoint id (not thread_id) keeps this correct even when two runs race on the same conversation (the job-replacement scenario). Correctness is preserved end-to-end: interrupt checkpoints + their pending writes persist exactly as before (resume unchanged); clean checkpoints were only ever written-then-pruned, so not writing them is observationally equivalent. The eager prune stays as the backstop. Tests (mongodb-memory-server): a bare put() is discarded; an interrupt-seeded checkpoint is persisted with its __interrupt__ pending write; and an end-to-end real-graph run writes 0 checkpoints on a clean completion and a resumable one on interrupt. NOTE: a non-paused turn's deleteAgentCheckpoint now finds nothing to delete (a 0-match no-op) — a follow-up can skip that call entirely once the lingering-abandoned-pause cleanup role is reassigned to the TTL + expiry sweeper. * ⚡ feat: Drop the redundant clean-path checkpoint prune With the lazy checkpointer (InterruptOnlyMongoSaver) a non-paused turn no longer writes a clean-exit checkpoint, so the post-completion prune in chatCompletion's finally had nothing left to delete. It was also already redundant: every fresh turn runs a pre-run prune (`deleteAgentCheckpoint` before `processStream`) that clears any checkpoint orphaned by a prior abandoned pause — verified empirically that a lingering interrupt checkpoint WOULD otherwise poison a fresh turn (LangGraph continues the abandoned state + re-interrupts), and that the pre-run prune is what prevents it. The Mongo TTL remains the backstop, and the resume path still prunes after a successful finalize. Removing the clean-path prune also deletes its job-replacement race surface (round-17 F21): an older run's late finally can no longer delete a newer paused run's checkpoint, because there is no longer a clean-path prune to race. Dropped the now-dead F21 predicate test. Net per non-paused HITL turn: from {pre-run prune + checkpoint write + post-run prune} down to {pre-run prune} — no write, no post-completion delete. * 🛡️ fix: Anchor any pending-write checkpoint; stale-only eviction (Codex) Broaden the lazy saver's keep-rule from "interrupt-only" to "persist any checkpoint that carries pending writes" (renamed InterruptOnlyMongoSaver → LazyMongoSaver). This makes it robust to delta-channel graphs without changing behavior for LibreChat's graph: - K1 (P1): a delta-channel graph can write a synthetic PARENT/anchor checkpoint (no __interrupt__ mark) that the interrupt checkpoint then points at, with the delta writes stored under the parent id. The old rule discarded that parent, breaking delta-state resume. Now any checkpoint that received putWrites is persisted, so the anchor parent and its writes survive and resume can walk the chain. - K3 (P2): for the same reason, clean delta-write rows are no longer orphaned — their checkpoint is persisted alongside them. (For LibreChat's standard Annotation/messages graph a clean run makes no putWrites at all — verified empirically — so the common path still writes nothing and the optimization is unchanged.) - K2 (P2): the 1024 FIFO cap could evict a valid in-flight id whose put() was just behind Mongo I/O, mis-classifying its interrupt checkpoint as a clean exit. Replaced with time-based eviction: only ids older than 5 min (a put always follows its putWrites within ms) are swept; a recent in-flight id is never dropped, and the map grows rather than evict a valid id if nothing is stale. New integration test: a checkpoint anchored by a NON-interrupt write is persisted. Full agents/HITL suites green (108). * style(checkpointer): fix import order to satisfy sort-imports CI * fix(checkpointer): don't persist failed-turn (error-only) checkpoints LazyMongoSaver anchored on ANY pending write, so a non-paused turn that errors (LangGraph records an __error__ write then a put) was persisted and, with the clean-path prune removed, lingered until the next fresh-turn prune or the Mongo TTL. Anchor only on resumable writes — INTERRUPT or a real (non-__-prefixed) state/delta channel — so error/bookkeeping-only checkpoints are discarded at the source. Addresses Codex P3. Codex P2 (delta-stub parent orphan) is not reachable: the SDK graph uses standard Annotation/MessagesAnnotation channels (no DeltaChannel), and under durability:'exit' putWrites precedes put with a parentless boundary checkpoint — probe-confirmed against @langchain/langgraph@1.4. Documented the durability:'exit' invariant the saver depends on. Tests: error-only put discarded; e2e throwing graph persists 0 checkpoints. * fix(checkpointer): drop bookkeeping-only write batches, not just the checkpoint The prior fix stopped the failed-turn CHECKPOINT from persisting, but putWrites still forwarded the __error__ batch to MongoDBSaver.putWrites — writing a row to agent_checkpoint_writes whose parent checkpoint is then discarded. With the post-run deleteThread removed, that orphan row lingered until the Mongo TTL or the conversation's next pre-run prune. putWrites now drops a non-resumable (bookkeeping-only) batch entirely instead of forwarding it. Probed against a real MongoDBSaver (mongodb-memory-server): a throwing graph now leaves 0 checkpoints AND 0 write rows (was 0 + 1 orphan), while interrupt->resume is unaffected — the __interrupt__ write is resumable so it is still forwarded. Addresses Codex P2 (round 3). Tests: error-only put leaves no checkpoint and no write row; e2e throwing graph leaves both collections empty; new e2e interrupt->resume completes with the approval value. * fix(checkpointer): un-anchor a checkpoint whose putWrites failed; freshen comments Self-review findings on the converged PR: 1. LangGraph dispatches put() concurrently with putWrites (probe-confirmed on 1.4.5), and put() still completes when putWrites rejects — so a transient Mongo failure during the interrupt write could persist a checkpoint whose __interrupt__ row is missing (an unresumable phantom pause). putWrites now deletes the write anchor on rejection (best-effort) and rethrows, so that put() discards the checkpoint instead. The pre-recorded anchor stays where it is — recording after the await would drop slow-I/O interrupts on the success path, which the same probe showed is reachable. 2. Renamed leftovers: two comments still said InterruptOnlyMongoSaver; the class is LazyMongoSaver. 3. Documented why the pre-run prune is deliberately unconditional per HITL turn (any cheaper gate can go stale across replicas and skip the prune exactly when an orphaned interrupt exists). Test: failed putWrites → subsequent put persists nothing (14/14 green). * fix(checkpointer): bookkeeping write batches follow their checkpoint's fate The round-3 rule dropped bookkeeping-only putWrites batches (__error__/ __resume__/__no_writes__) unconditionally — batch-scoped, when the decision must be checkpoint-scoped. Probe-confirmed (langgraph 1.4.5, durability:'exit'): a Send fan-out that pauses on one sibling records the completed siblings as pure __no_writes__ batches on the RETAINED interrupt checkpoint; dropping those markers makes resume re-execute the completed siblings (side effects measured twice). Addresses Codex M2 (P2). putWrites now PARKS a bookkeeping-only batch in memory until the checkpoint's fate is known: forwarded when the checkpoint is anchored (or was just persisted — put is dispatched concurrently), dropped when put discards it. Net: an errored turn still leaves nothing durable (0 checkpoints, 0 write rows), and a retained checkpoint stores byte-for-byte what a plain MongoDBSaver would. Codex M1 (__resume__ lost on re-pause) did not reproduce: the re-pause emits [__interrupt__,__resume__] as ONE batch (anchored, forwarded whole) and a second resume on a rebuilt graph replays both answers correctly — but the fate-scoped buffering now covers a lone __resume__ batch in any ordering too. Tests: bookkeeping preserved on a retained checkpoint in either arrival order; e2e Send-sibling pause/resume with side-effect counters (was {a:2,c:2} under the drop rule, now {a:1,c:1}); error-only turn still leaves both collections empty. 16/16 green. |

🪝 feat: Configurable Tool-Approval Policy via Programmatic Hooks (#14025)

* 🪝 feat: Programmatic tool-approval hook seam (configurable beyond on/off) Adds a process-wide registry so host code can plug context-aware PreToolUse decision hooks into the tool-approval policy, composing with the static `endpoints.agents.toolApproval` config instead of replacing it. - `registerToolApprovalHook(factory, { matcher? })` — register a factory that builds a PreToolUse hook per run from a ToolApprovalHookContext (userId, conversationId, tenantId, appConfig); return undefined to opt the run out. Returns an unregister fn. - `buildHITLRunWiring(policy, context)` now registers the static-config policy hook as the baseline, then layers each resolved host hook after it. Decisions fold in the SDK as deny > ask > allow, so a host hook can only TIGHTEN a configured ask/deny — it can never silently auto-approve past policy (to loosen, change the static policy). updatedInput / allowedDecisions follow the SDK's last-writer-wins, so host hooks win over the baseline. - `createRun` threads the per-run context (user / conversation / tenant / appConfig) into the wiring; non-HITL and HITL-disabled runs never invoke any factory. This unlocks dynamic policy the static name-lists can't express — per-args (e.g. ask before write_file outside a workspace, the SDK's createWorkspacePolicyHook shape), per-agent, per-user. Inert until tool approval is enabled and the caller is hitlCapable. Tests: registry register/unregister/opt-out/order (hooks.spec.ts) + wiring composition, context passthrough, and disabled-path inertness (runtime.spec.ts). Full HITL suite green. * 🪝 feat: Config-driven tool-approval hook loader (librechat.yaml → hook modules) Lets operators declare programmatic tool-approval hooks in config instead of code, so the registerToolApprovalHook seam is usable without a custom build. - Config (data-provider): `endpoints.agents.toolApproval.hooks[]`, each entry `{ module, matcher?, options? }`. `module` is a bare package name or a path (resolved against the app root); its default export is a builder `(options?) => ToolApprovalHookFactory`. - Loader (@librechat/api `loadToolApprovalHooks`): imports each module, builds the factory with the entry's options, and registers it (with its optional tool-name matcher). Reload- safe (each call first unregisters its previous batch, leaving code-registered hooks alone) and robust — an unimportable module / non-function export / throwing builder is logged and skipped, never crashing startup or blocking the other hooks. Importer is injectable for tests. - Startup (api/server/index.js): loads the configured hooks once after appConfig resolves. SECURITY: modules are dynamically imported + executed in-process; this is admin-level config, documented as trusted-code-only. Tests: 9 loader cases (default/no-default export, options passthrough, bad-export skip, builder-returns-non-function skip, import-failure resilience, continue-past-bad-entry, reload de-dup). Full HITL suite green (80). * 💄 style: Sort imports in HITL hook spec files (CI sort-imports:check) * 🛡️ fix: Harden tool-approval hook loader (Codex review) Six P2 findings on the hook loader / startup wiring: - CJS/transpiled interop: unwrap a nested `default` (TS/Babel `exports.default = fn` surfaces through import() as `{ default: { default: fn } }`) before rejecting a module, so documented default-export hook modules actually load. - Validate the matcher regex at load time and skip invalid ones — the SDK compiles it with `new RegExp` at run-build time, where a bad pattern would throw out of buildHITLRunWiring and break EVERY HITL run instead of just skipping the one bad hook. - Honor the `enabled` kill switch: startup now passes hooks to the loader only when toolApproval is enabled, so a disabled endpoint imports/runs nothing (and unregisters any prior batch). - Resolve app-root-relative paths without a leading dot: a bare specifier that is a real file under basePath (e.g. `config/hooks/workspace.js`) resolves as a path; scoped/other bare names still import as packages. - Base-config-only: documented that hooks register once process-wide at startup and are NOT reloaded from per-role/user/tenant overrides — encode per-tenant logic inside the hook. - Wire the loader into the clustered startup path (api/server/experimental.js) too, not just the standard server. Tests: CJS-interop unwrap, invalid-matcher skip (+ sibling still loads), and specifier resolution (app-root file / bare package / ./relative). Full HITL suite green. * 🛡️ fix: Read tool-approval hooks from base config in clustered startup (Codex) The clustered experimental.js path read toolApproval from getAppConfig() (which merges DB __base__ overrides with no principal), so a DB override could enable/disable/replace toolApproval.hooks and import those modules in every worker — violating the base-config-only contract and diverging from the standard server. Fetch getAppConfig({ baseOnly: true }) specifically for the hook loader, matching api/server/index.js. |

⚡ perf: Minimize group membership query in principal resolution (#14055)
getUserPrincipals resolves a user's ACL principals on nearly every
authenticated request. It fetched full group documents (including entire
memberIds arrays) only to read each group _id, and always issued a
separate User lookup for idOnTheSource.
- Project { _id: 1 } on the memberIds group query so it returns only ids
and can be served from the { memberIds: 1 } index instead of fetching
and decoding whole group docs.
- Accept role and idOnTheSource from the already-loaded request user and
thread them from the capability middleware, collapsing the hot path to
a single indexed group query (idOnTheSource: null means known-local).

Thinking tokens share the maxTokens output budget with tool-call
arguments (e.g. a create_file content), so the low Bedrock defaults
(8192 for enabled thinking, ~4096 server-side for adaptive when unset)
truncated large authored files mid-argument — surfacing as
OutputTruncationError once reasoning actually emits.
Default maxTokens to the model's full max output via
anthropicSettings.maxOutputTokens.reset(model), mirroring the
direct-Anthropic path. Explicit maxTokens/maxOutputTokens are respected.

* 🧠 fix: Apply Bedrock thinking config to bare inference-profile model IDs The Bedrock request parser gated thinking config, sampling handling, and the anthropic_beta headers on the model ID literally containing `anthropic.`. When a deployment uses an application inference profile, the LibreChat model ID is a bare `claude-*` (e.g. `claude-sonnet-5`) that maps to the profile ARN — so the gate never matched, no `thinking` config was sent, and reasoning models returned empty thinking blocks (most visibly: Claude Sonnet 5 never streamed reasoning, while `us.anthropic.claude-opus-4-8` did). Match on the `claude` family token instead of the `anthropic.` prefix so prefixed (`anthropic.`, `us.`, `global.`) and bare inference-profile IDs are handled identically. Verified e2e against live Bedrock via the agents SDK: a bare `claude-sonnet-5` now sends `{type:'adaptive', display:'summarized'}` and streams reasoning. Non-Claude Bedrock models (llama/cohere) and pre-thinking Claude (3.5 sonnet) are unaffected. * 🧹 fix: Strip stale thinking fields for non-thinking Claude Bedrock IDs Follow-up to the bare-ID matching change: broadening the anthropic guard to match bare `claude-*` meant a non-thinking Claude profile (e.g. a bare `claude-3-5-sonnet` inference profile) took the Claude cleanup branch, which kept persisted `thinking`/`anthropic_beta`/`output_config` from a previously-selected thinking model — leaking unsupported fields after a model switch. Extract `isThinkingModel` and, in the Claude cleanup branch, strip the thinking fields when the model isn't thinking-capable. Also fixes the pre-existing prefixed `anthropic.claude-3-5-sonnet` case (which already kept stale thinking). Thinking-capable models (sonnet-5, 3.7-sonnet) still keep their config. * 🩹 fix: Preserve user anthropic_beta on non-thinking Claude cleanup The non-thinking stale-cleanup deleted amrf.anthropic_beta, but that is the generic Bedrock Anthropic beta field and may carry a user opt-in (e.g. max-tokens-3-5-sonnet-2024-07-15 for extended output on Claude 3.5). Strip only the thinking-specific fields (thinking/thinkingBudget/effort/output_config) and leave anthropic_beta intact. * fix: clear persisted AMRF (output_config, thinking, generated betas) on bare Bedrock profiles * fix: preserve persisted effort on resume + strip stale thinking/betas across bare profiles * fix: normalize string/comma-delimited anthropic_beta before stripping generated betas |

🩹 fix: Coerce Stringified edit_file Edits (JSON-in-JSON) (#14056)
Models sometimes pass edit_file's `edits` as a JSON-encoded string (or stringify individual edit entries) instead of a real array. That failed validation with "Provide old_text and new_text, or a non-empty edits array" and forced a full retry round-trip. normalizeEditArgs now JSON-parses a stringified `edits` value (and stringified entries) before validating. Non-strings and unparseable strings are left untouched, so the existing explicit errors still fire. |

🫷 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 |

🔥 fix: Firebase CDN Initialization Under tsdown CJS Interop (#14046)
The `@librechat/api` build migrated to tsdown (rolldown/oxc) in #13595. tsdown externalizes third-party deps and uses strict CJS interop, so a default import of the Firebase v9+ modular SDK — whose CJS entry is `__esModule`-marked with only named exports and no `default` — resolves to `undefined`. `firebase.initializeApp(...)` then throws: TypeError: Cannot read properties of undefined (reading 'initializeApp') crashing startup whenever the Firebase file strategy is configured (`fileStrategy: firebase` or a granular `fileStrategies` entry). Switch to the idiomatic modular named import (`initializeApp`) and use the already-imported `FirebaseApp` type for the return annotation. |

📥 fix: Download Original File From Artifact Preview Panel for Office Documents (#14026)
* fix: download original file from artifact preview panel for office documents The preview panel download button serialized the rendered HTML preview instead of the original binary for office artifacts (pptx/xlsx/docx) produced by the code interpreter, so users got an `index.html` text scrape rather than the file. The inline chat card was unaffected because it downloads the real file via `useAttachmentLink`. Thread the original-file download metadata (filepath/file_id/source/user) through `fileToArtifact` onto the Artifact, and update `DownloadArtifact` to fetch the original file through that same path for preview-only office artifacts. Text, source, and markdown artifacts keep the blob path so their in-panel content (and edits) still download as-is. Closes #14002 * fix: require a usable route before downloading the original artifact file A shared link to a non-snapshotted code-execution office artifact strips source/user and deletes filepath while keeping file_id (share sanitization + applyShareFileRoute). The preview-panel download gate treated that lone file_id as sufficient, so it routed to an empty useCodeOutputDownload fetch and downloaded nothing instead of falling back to the preview-content blob. Take the original-file branch only when useAttachmentLink can actually fetch: a non-empty filepath (http target, share route, or code-output URL) or full local-file metadata (isLocallyStoredSource + file_id + user). Export isLocallyStoredSource from LogLink so the panel reuses the same predicate. * fix: only show artifact download success after the file is delivered useAttachmentLink swallows fetch errors (an expired code-output URL or a 404 share download) and resolves without throwing, so the preview-panel download button flipped to the success checkmark even when no file was downloaded. Return a boolean from handleDownload (true once a download is initiated, false on error/empty response) and only mark the artifact download as succeeded when a file was actually delivered. The return value is ignored by the existing onClick callers. |

🥷 feat: Add showInMenu Option to Model Specs (#14034)
Add an optional `showInMenu` flag to model specs. When set to false, the spec is dropped from the model selector menu and from the client startup config (GET /api/config), but remains resolvable server-side by name — a request that sends `spec: "<name>"` still works, since server-side resolution uses the full, unfiltered list. Unlike `showIconInMenu` (which only hides the icon), this hides the whole entry. The flag is optional and defaults to listed, so existing specs are unaffected. Adds an `excludeHiddenModelSpecs()` helper (applied before `sanitizeModelSpecs`) plus unit tests. |

📏 fix: Make create_file Missing-Content Error Truncation-Aware (#14043)
A large SKILL.md/file authored in one create_file call can exceed the model's max output token budget; the response is cut off before the content argument finishes, the arg is dropped, and the handler returns a bare 'content is required'. The model reads that as a forgotten field and retries the same oversized write, looping. Make the error actionable: tell the model the response may have been truncated and to keep the main file lean, moving bulky sections into separate files written in their own calls. |

🤖 feat: Add Claude Sonnet 5 Support (#14042)
* ✨ feat: Add Claude Sonnet 5 Support Wire up the claude-sonnet-5 model across token, pricing, and model-list config: - Context window (1M) and max output (128K) in @librechat/api token maps - Standard pricing ($3/$15 per MTok) and cache rates in data-schemas tx - 128K output-token carve-out in anthropicSettings (the family-wide 64K rule capped Sonnet 5 below its real limit); Bedrock/Vertex thinking and 1M-context detection already cover sonnet major >= 5 generically - Add to shared Anthropic, Bedrock, and Vertex default model lists, plus the .env.example examples - Tests for context/output/pricing/matching across the affected packages * ✅ test: Align Sonnet 5+ maxOutputTokens defaults with 128K spec getLLMConfig defaults flow from anthropicSettings.maxOutputTokens.reset(), which now returns 128K for Sonnet 5+. Update the future-proofing assertions in llm.spec.ts (Sonnet 5.x and 6-9.x) that still expected the old family-wide 64K cap. Haiku stays 64K; Opus stays 128K. * 🎚️ fix: Gate Sonnet 5 capability behaviors (sampling, thinking) Adding claude-sonnet-5 to the default list exposed it without the Anthropic capability gates, all confirmed against the live API: - omitsSamplingParameters: Sonnet 5 returns 400 on non-default temperature/ top_p/top_k ('deprecated for this model'); now dropped so selecting the model with saved sampling settings no longer fails. - requiresExplicitThinkingDisabled: omitting 'thinking' runs adaptive ON by default on Sonnet 5, so disabling thinking now sends { type: 'disabled' } (verified: 200, no thinking block) instead of omitting the field. - omitsThinkingByDefault: thinking.display defaults to omitted (empty thinking blocks); the display resolver now returns 'summarized' for Sonnet 5+ so the Thoughts UI keeps working (verified: 757-char summary returned). Gates apply to both the direct Anthropic and Bedrock paths. Tests added in bedrock.spec and llm.spec. * 🩹 fix: Sonnet 5 Bedrock availability + thinking-off persistence Round-2 Codex review (all verified against the live API / Anthropic docs): - Sonnet 5 is NOT available on the legacy Bedrock InvokeModel/Converse surface (Anthropic docs: 'use Claude in Amazon Bedrock or Claude Platform on AWS'), which is what LibreChat's ChatBedrockConverse uses. Removed it from the default Bedrock model lists (config + .env.example). Opus 4.8/4.7/Fable 5 stay — those ARE reachable via InvokeModel. Sonnet 5 remains on the direct Anthropic API and Vertex, where it works. - Reverted the Bedrock-side explicit-disabled thinking handling added last round: with Sonnet 5 off Bedrock, no Bedrock model needs { type: 'disabled' }, so that path (and its round-trip concern) no longer applies. - Direct Anthropic path: a persisted { type: 'disabled' } thinking object now normalizes to a boolean flag in getLLMConfig, so a user's Sonnet 5 'thinking off' setting stays off across the model_parameters round trip instead of flipping back to adaptive (a truthy object skipped the disabled branch). * ↩️ fix: Restore Sonnet 5 on Bedrock (Converse) — verified live Reverses the round-2 removal: Sonnet 5 IS available on AWS Bedrock. Tested live via the Converse API: - global.anthropic.claude-sonnet-5 returns a normal response - bare anthropic.claude-sonnet-5 needs an inference profile — but that's identical to the already-shipping Opus 4.8 / Fable 5 / Sonnet 4.6 entries, which all fail bare on-demand the same way - temperature=0.5 -> 400 'deprecated for this model'; thinking {type:disabled} suppresses reasoning — same as the direct API The 'legacy' Bedrock docs page that claimed Sonnet 5 wasn't on the surface is stale. Restored: - anthropic.claude-sonnet-5 in bedrockModels + .env.example - the Bedrock explicit-disabled thinking handling (requiresExplicitThinkingDisabled -> { type: 'disabled' }) - the Finding 4 round-trip fix in bedrockInputSchema (coerce a persisted disabled AMRF.thinking to thinking=false instead of !!thinking -> true), with an end-to-end schema->parser test proving 'thinking off' stays sticky. Direct-path round-trip fix (getLLMConfig thinkingFlag) is unchanged. * 💵 fix: Sonnet 5 intro pricing + sticky disabled thinking on Bedrock reload Round-4 Codex review (both verified): - Pricing: Anthropic lists Sonnet 5 at introductory $2/$10 per MTok (cache $2.50/$0.20) through 2026-08-31, reverting to $3/$15 ($3.75/$0.30) on Sep 1 (confirmed on platform.claude.com/pricing). The static tx multiplier table is used for real balance transactions, so the post-intro rates were overcharging ~50% during the launch window. Switched to the intro rates with a revert comment on both the token and cache entries. - Bedrock disabled-thinking persistence: initializeBedrock feeds persisted model_parameters straight through bedrockInputParser (NOT bedrockInputSchema), where additionalModelRequestFields is a known key — so a prior thinking:{type:'disabled'} was ignored and rebuilt as adaptive on reload. bedrockInputParser now surfaces a persisted disabled AMRF.thinking as thinking=false so it re-emits {type:'disabled'}. Verified end-to-end against the real initializeBedrock call path. |

🗺️ refactor: Light Up In-Viewport Ribs at Rest in Message Nav (#14041)
At rest (no hover/focus) the rail now reads like a minimap: only the in-viewport message ribs are at full opacity while the rest fade to 40%, updating live as you scroll. Replaces the blanket nav opacity-30 with per-rib opacity driven by the existing viewport-visibility highlight, so hover/focus still brings every rib to full opacity for the fisheye. |

* ✨ feat: Dock-Fisheye Message Nav Rail with Instant Hover Preview * 🎚️ refactor: Uniform resting ribs + clickable cursor for message nav * 🧹 fix: One rib per message in nav rail (dedupe nested message-render) * 🎯 fix: Accurate fisheye focus + click-anywhere-to-jump in message nav - Measure rib centers relative to the column (getBoundingClientRect) instead of offsetTop, which was relative to the positioned <nav> and shifted the pointer->rib mapping by the chevron height (hovered line wasn't the peak, preview showed an earlier message). - Column-level click jumps to the focused rib, so clicking anywhere the preview is showing works even when the pointer is off the thin line. - Restore @librechat/client jest stub to keep the unit isolated. * 💡 fix: Highlight only the hovered rib white in message nav * 🫥 style: Transparent message nav (drop pill background) * ♿ feat: Keyboard focus mirrors hover (magnify + highlight + preview) in message nav Tabbing to / Shift+Alt+M focusing a rib now drives the same fisheye pipeline as pointer hover via onFocus/onBlur on the column: the focused rib magnifies, highlights white, and shows the shared preview. Also addresses Codex finding on keyboard-focus previews. * 🩹 fix: Live tooltip preview + legacy media-query fallback in message nav - Derive the shared preview text from entryById at render time instead of snapshotting it into tip state, so a streaming/updating message refreshes the open tooltip without leaving and re-entering the rail. - Feature-detect MediaQueryList.addEventListener and fall back to addListener/removeListener so the reduced-motion watcher no longer throws (and breaks the nav) on Safari/iOS < 14. Addresses both Codex findings on review 4601236141. |

⚡ perf: memoize FavoritesList and BookmarkNav to prevent re-renders during streaming (#14011)
* perf: memoize FavoritesList and BookmarkNav to prevent streaming re-renders ConversationsSection re-renders during message streaming as its conversation-list query and title generation update the cache. Its FavoritesList and BookmarkNav children were not memoized, so they re-rendered on every parent commit despite their props and subscriptions never changing during a stream. Wrap both in React.memo to insulate them from the parent cascade. Their props (toggleNav, isSmallScreen, tags, setTags) are referentially stable, so memo fully decouples them. Add a regression test asserting FavoritesList does not re-run when its parent re-renders with stable props. * test: verify ConversationsSection insulates Favorites/Bookmarks from streaming re-renders Renders the real ConversationsSection (mocking only data hooks) and forces repeated re-renders via a subscription it depends on, mirroring the conversation-list/title-generation cache churn during streaming. Asserts FavoritesList and BookmarkNav do not re-render, proving the parent passes referentially stable props so React.memo holds in the real render path (not just with hand-fed stable props). |

* 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).

* 🪟 fix: Re-measure sidebar chat list on width change to fix date-group spacing When the sidebar is expanded from a collapsed reload, virtualized rows first measure mid-animation at a narrow width, so date-group headers wrap and cache an inflated height. CellMeasurerCache(fixedWidth) keys heights by row, not width, so the stale height persists once full width is reached — leaving gaps under headers. Invalidate the measurement cache and recompute row heights whenever the measured list width changes. Adds a Playwright mock e2e (seeds backdated convos across date groups via a new db helper) that fails without the fix and passes with it. * 🧪 test: Harden sidebar e2e (runtime-env path, midnight-safe seed, convo isolation) Addresses Codex review on PR #13981: - db.ts honors E2E_RUNTIME_ENV_PATH when locating the runtime Mongo URI. - Seed timestamps anchor on local noon so the Today group stays in-day near midnight. - Clear the shared user's conversations before seeding so later date-group headers are not pushed below the virtualized viewport by other specs' leftover chats. |

🛗 perf: Fetch Pinned Agents Directly Past the Global Agents Map (#13972)
Some checks are pending
Docker Dev Branch Images Build / build (Dockerfile, lc-dev, node) (push) Waiting to run
Docker Dev Branch Images Build / build (Dockerfile.multi, lc-dev-api, api-build) (push) Waiting to run
GitNexus Index / index (push) Waiting to run

* 🚀 perf: Decouple Pinned Agents from Global Agents Map in Sidebar Pinned/favorite agents in the sidebar waited for the full global agents map (useListAgentsQuery, which walks every pagination cursor) before rendering. In environments with many agents this left pinned items in a loading state even though their IDs were already known. FavoritesList now fetches pinned agent IDs directly via getAgentById when the global map is still loading, and falls back to filtering only missing IDs once the map is available. The loading state tracks just the small set of pinned-agent queries instead of the entire catalog, so pinned agents appear as soon as their own data resolves. Closes #13967 * 🩹 fix: Address Codex review on pinned-agent decoupling - Stop caching the {found, agent} wrapper under the shared [QueryKeys.agent, id] key; direct fetches now return a plain Agent like useGetAgentByIdQuery, so opening/selecting a pinned agent within the stale window can no longer read a wrapper as an agent. Missing (404/403) agents are detected via the query error state. - Gate the direct fetches on the agents endpoint being enabled, so pinned agents the endpoint list intentionally hides are not fetched, rendered, or cleaned up when the endpoint is disabled. - Keep the loading skeleton while a direct fetch fails with a transient (non-404/403) error and the global agents map is still loading, so a pinned agent no longer disappears on a momentary 500/network error during startup. - Remove the now-unused AgentQueryResult type. * 🩹 fix: Address Codex round 2 on pinned-agent decoupling - Keep the loading skeleton (not an empty/collapsed row) while the endpoints query is still loading. The endpoint gate previously treated the default empty config as disabled, so pinned-agent favorites rendered an empty row that could be measured and cached by the CellMeasurer before the config arrived. isAgentsLoading now stays true while isEndpointsLoading is true. - Replace the blanket retry:false on direct pinned-agent fetches with a predicate that skips missing-agent (404/403) errors but still retries transient 500/network failures, restoring the prior default-retry resilience on the fast path. - Add data-testid to the favorite skeleton and a regression test for the endpoints-loading window. * 🛡️ fix: Don't delete pinned favorites on a global agents 403 GET /api/agents/:id runs the role-level AGENTS.USE check (checkAgentAccess) before the per-agent VIEW ACL, so a temporarily revoked role returns 403 for every agent. Because direct fetches now run while the agents map is undefined, treating those 403s as missing agents made the cleanup effect persist reorderFavorites and wipe all pinned agent favorites. staleAgentIdsKey now returns early while agentsMap is undefined, restoring the original invariant that favorite cleanup only runs once the global map has loaded successfully (which also proves AGENTS.USE is granted). Rendering of pinned agents while the map loads is unaffected; only deletion is deferred. |

📂 fix: Mount Skill Files Under skills/ in Code Interpreter (#13961) (#13975)
Skill files were primed into the sandbox at `/mnt/data/{skillName}/...`,
but the read_file/create_file/edit_file tool descriptions and the
read_file bash-fallback hints all assume the `skills/{skillName}/...`
namespace (sandbox cwd is `/mnt/data`). Agents therefore reached for
`./skills/my-skill/...` in bash and missed ~100% of the time.
- Add shared `SKILL_FILE_PREFIX` to agents/skills.ts (moved out of
handlers.ts; single source of truth across the three layers).
- Prefix the prime upload filenames and session names with `skills/` in
skillFiles.ts so the physical mount matches the model-facing namespace;
recover the bare relativePath by stripping `skills/{name}/`.
- Canonicalize the read_file bash-fallback hints to
`/mnt/data/skills/{skillName}/{relativePath}` so the implicit
`{name}/...` addressing form is corrected too.
Closes #13961

🦥 perf: Lazy-Load Agent Version History in Editor (#13977)
Opening the agent editor fetched the full `versions` array (each a complete config snapshot) alongside the agent, so agents with large histories were slow to open. Version history is now loaded only when the user opens it. - Add `getAgentWithVersionCount` (aggregation: version count, no versions array) and `getAgentVersions` data-schemas methods. - `getAgentHandler` returns the version count without the heavy array; add `GET /agents/:id/versions` (EDIT-gated) for lazy retrieval. - Add `useGetAgentVersionsQuery`; VersionPanel reads current config from the cached expanded query and fetches versions on open. Revert keeps the expanded cache and versions query in sync. |
