A good part of this project is written with them, and we do not judge a pull request by whether a model helped write it. What we do ask is that agent-assisted work arrives the same way human work always has: attached to an issue, claimed in the open, and expected by someone. + +An agent makes a patch cheap to produce, which moves the whole cost of it onto the person reviewing it.

Sweeping open issues and emitting patches for them is not a contribution; it asks a maintainer to review work they never scoped, on an issue that may already belong to someone else. Being first to a patch does not claim an issue, and an issue assigned to another contributor is not available even if your fix is better. + +### What we close on sight + +These are patterns we actually receive, not hypotheticals: + +- **Batches.** Several unrelated pull requests opened minutes apart, or the same sweep run across many projects at once.

Keep the diff to the lines you changed, and configure your tooling not to rewrite the rest (`git config core.autocrlf input` on Windows). An unreadable diff hides things, including reverts of recent commits your branch predates. +- **Unverifiable claims.** A description asserting a bug, a root cause, or a passing test suite with nothing a reviewer can reproduce. Say what you ran and what you did not. +- **A patch you cannot discuss.** You are the author of anything you submit.

"Minimum" describes how much behavior `/api` gains, not how small the diff is: + lifting a function into `/packages/api` and calling it is the larger diff and the correct one. + Editing an existing CJS file is the common case and the rule applies there, not only to new files. - Database-specific shared logic goes in `/packages/data-schemas`. - Frontend/backend shared API logic (endpoints, types, data-service) goes in `/packages/data-provider`. - Build data-provider from project root: `npm run build:data-provider`. +- **Database contracts stay inside `/packages/data-schemas`.** A Mongoose type in an exported + signature — `FilterQuery`, `Types.ObjectId`, `Document`, `HydratedDocument` — makes the storage + engine part of that module's public API, and every consumer then depends on Mongo instead of on + the data it needs. Take and return plain typed objects, and express the query behind a + data-schemas method. The boundary already leaks across dozens of files in `/packages/api`, so the + rule is to stop widening it rather than to rewrite what exists; `/client` carries none of it and + must stay that way. +- **New levers ship configurable.** A limit, timeout, toggle or capability introduced in code earns + a field on `configSchema` (`packages/data-provider/src/config.ts`) so an operator can set it in + `librechat.yaml`, with a default that reproduces today's behavior. Hard-coded constants and + env-only switches need a reason. The schema is also what keeps one definition of the value instead + of a constant, a fallback and a doc line that drift apart. +- **A backend module takes its dependencies, it does not reach for them.** Code in `/packages/api` + should receive its config, database methods and clients from the caller the way + `createModels(mongoose)` receives the app's connection, rather than importing app singletons or + reading global state. A module the caller constructs can be tested without a running app and moved + to another workspace without a rewrite; one that calls `getInstance()` can do neither. This is the + backend half of "Client State Ownership" — pass it in, do not reach for it. The static singletons + under `packages/api/src/mcp` are the shape to stop extending, not a pattern to copy. +- **Integrations arrive through an interface the caller supplies.** A provider SDK, storage backend, + vector store or OAuth server is injected, so a second implementation is a new argument instead of + a new branch in shared code, and a test can exercise the real logic against a substitute at the + boundary rather than mocking the module that holds it. + +--- + +## Branching and Pull Requests + +- **Branch off `dev`, and target `dev` with every pull request.** All work lands on `dev` first. +- **`main` is the released branch.** It is kept as a fast-forward of `dev` and synced as-is, so it + is always an ancestor of `dev` — equal to it right after a sync, behind it otherwise.

Backport branches are deliberately not exempt — + a backport merged straight to `main` is what breaks the fast-forward invariant. +- **`Fixes #N` does not close the issue.** GitHub honors closing keywords only when a pull request + merges into the default branch (`main`). Merging to `dev` does not close anything, and the later + fast-forward of `main` is not a merge event either — close linked issues by hand. +- **Git worktrees share one stash stack.** `refs/stash` lives in the common `.git` directory, so a + bare `git stash pop` in one worktree can take work stashed in another. Prefer a throwaway WIP + commit; if you must stash, `git stash push -m ` and `apply` that specific entry. +- **Write the description for a reader who has not followed the branch.** Say what breaks, what + triggers it, and how it behaves after the change, then show the mechanism with whichever one or + two views make it reviewable — a focused diff, a call tree, a shallow file tree, or a Mermaid + sequence — keeping only the calls, files and state the change actually carries.

It owns cancellation and lease revalidation until a generation slot is reserved; a slow or failed readiness check never occupies generation capacity. + +- **Attached code environment**: A principal- or deployment-authorized stateful workspace owned by an outbound `librechat-code` worker on a user-chosen machine or VM. LibreChat selects it and enforces approval policy, Code API authenticates and dispatches to it, and the worker's local sandbox and capability flags remain the final execution ceiling. The environment interface is runtime-neutral: native SRT, WSL2, Docker/NsJail, and future adapters expose the same workspace operations without leaking host paths or runtime configuration into agent tools. +- **Conversation code-environment decision**: The immutable choice established by a conversation's first accepted submission between validated attached workspaces and continuing without an attached environment. Agent defaults and recent workspace preferences may suggest a draft choice, but only the persisted conversation decision authorizes attached workspace tool registration; later turns, retries, resumes, and alternate ingresses cannot upgrade or replace it. Runs persist a decision only for a conversation that does not store one yet, so no run writes its run-start decision back over a stored one. The one exception to immutability is the owner's explicit move, available where `statefulCodeSessions.conversationMoves.enabled` allows it: when an agent is pointed at a different attached environment after the chat was sealed, the owner may replace the decision's environments with the ones the agents now use, validated against the live worker. A move never changes the workspace of an environment the decision already covers, never upgrades a conversation that continues without an attached environment, and is refused while a generation is running, awaiting approval, or saving its response. +- **Agent run envelope**: the versioned, JSON-safe request contract created after ingress authentication and protocol validation but before agent, provider, tool, or MCP initialization. It carries only the validated protocol payload and the minimum trusted principal identifiers. The execution host rehydrates all runtime state from those identifiers. +- **Agent execution context**: runtime-only, transport-free state rehydrated beside an Agent run envelope. It contains the authenticated user, application configuration, normalized request metadata, and resolved conversation facts needed by initialization, but never Express request/response objects or serialized credentials. +- **Agent execution host**: the protocol-neutral module that owns run admission, disconnect cancellation, provider-start fencing, and terminal settlement. Protocol implementations execute behind its callback interface; HTTP adapters retain validation and final stream rendering. +- **Agent execution enrollment**: the durable, protocol-neutral lifecycle authority for an admitted Agent run. It is created under the authenticated user and tenant before user-owned initialization, rechecks the shared owner-deletion admission fence after registration, exposes the only provider abort signal, fences exact provider start, terminalizes the run, waits for every trailing usage, artifact, and stored-response write, and acknowledges provider drain last. A transient terminalization failure is reconciled after trailing writes; provider drain is never acknowledged while the exact job remains nonterminal. Delete-all holds the owner fence, drains every owner run before selecting its first persistence snapshot, and repeats both the drain and an idempotent owner-persistence sweep after any recovered fence lapse before releasing admission. Exact-conversation deletion additionally performs an unconditional idempotent cleanup over its immutable deleted-ID set because a fully drained run may leave the active index after racing the first delete; only the explicit empty result is benign, while storage failures remain fatal. Chat Completions, Responses, Channels, and future ingress adapters share this authority without moving LibreChat persistence policy into the Agents SDK. +- **Agent turn execution plan**: the immutable, request-local decision compiled once after authentication, agent resolution, and tool initialization. It records the trusted turn origin, conversation lineage, pause capability, binding/action context, and the preferred checkpoint, history, or fresh state-loading strategy without executing the model or owning persistence. Checkpoint failure falls back to durable history within the same Agents lifecycle. +- **Turn delivery routing**: the per-agent, request-local value that decides how each attachment reaches the model on one turn (`provider`, `text`, or `none`). Initialization settles it once, after the provider swap and the Responses API decision, under the endpoint's own name and the media dialect its config declares. Every reader of a turn route consumes that one value rather than deriving it from the agent. A stored route is an upload-time inference that this value resolves again for the turn; a destination the user chose stands. +- **Effective agent selection**: the resolved endpoint and agent identity after an enforced model spec is applied. Authorization and agent loading must consume this same identity before the Agent run envelope is initialized. +- **MCP runtime request body**: trusted chat identifiers supplied only while an MCP server handles an agent request. It enables request-scoped header placeholders without retaining user-specific request data on a shared server definition. +- **MCP direct OpenID bearer**: an operator-trusted remote MCP credential mode that resolves the logged-in user's live OpenID access token into an Authorization header. It may replace one rejected connection after a forced session refresh, but it never replays the rejected tool invocation automatically. +- **MCP OAuth prompt projection**: the client-safe, generation-scoped view of authorization prompts that remain actionable in a resumable Agent stream. It is derived from durable OAuth step state, carries no tokens or flow internals, and lets reconnecting clients render current state without interpreting the replay log. +- **Caller Capability Projection**: the versioned, SDK-owned classification of currently active tools by direct and programmatic callers. Event-driven execution transports this projection as data; LibreChat intersects it with its trusted registry and never recomputes deferred-tool discovery policy or treats the projection as authorization. +- **Subagent thread**: a durable, view-only child conversation owned by one parent conversation and subagent identity. A parent agent may continue it by stable `threadId`; each continuation uses a fresh execution lease restored from the canonical child transcript. It is not an ordinary human-writable chat. +- **Live subagent task owner**: the one API process holding a detached child execution, its abort controller, and its bounded control queue. Redis may route trusted poll/control envelopes to that owner, but it does not migrate or persist the executor; Mongo persists only the logical child thread and its continuation fence. +- **Subagent completion wakeup**: a durable internal `continue` trigger pre-registered before detached child execution so a process crash cannot lose the wakeup. Delivery defers until the child's terminal transcript is persisted, targets the initiating agent and exact parent response branch, carries task metadata rather than child output, waits for the parent generation to settle, and starts the parent turn that collects the result through the existing task store. +- **Agent continuation preparation**: the single source-dispatch seam that resolves a durable `continue` delivery immediately before admission. Bound Event Actor work selects its binding adapter; internal completion work selects an adapter by stable source identity. Preparation may resolve authoritative input and branch state or settle already-consumed work, but it does not own source result truth, delivery ordering, or generation execution. +- **Warm terminal steer continuation**: a queued steer accepted before a generation's terminal boundary may continue the same SDK `Run` without creating a replacement generation. After parallel Stop hooks fold, the serialized StopFinalize phase tells the job store whether another continuation is already planned or terminal progress is forbidden. The store atomically chooses among claiming the current protocol-v2 FIFO batch, keeping empty admission open for an already-planned segment, and sealing admission so every racing or later message becomes an ordinary follow-up. Claimed steer receipts remain the crash-recovery authority; protocol-v1 generations always seal because they cannot recover an ambiguous terminal claim. Tool-batch, preemption, and terminal boundaries share one durable apply-and-inject adapter, while the SDK owns the bounded Stop-continuation loop. +- **Agent queued turn**: a server-owned ordinary follow-up accepted while an Agent generation is active. Its Mongo row is the sole FIFO, payload, and lifecycle authority; the trigger delivery is only a replayable wakeup and Agent execution enrollment is only an execution adapter. The lifecycle reserves the deterministic delivery identity before publication, admits only after the captured branch has a clean durable predecessor outcome, and commits the source-owned generation receipt only after provider invocation has been enrolled. An accepted or deduplicated loopback response requires that exact receipt; a process death before it remains explicit admission-indeterminate evidence instead of silently consuming the text. Admission reconciliation is leased, backoff-scheduled work: exact generation evidence may repair legacy ambiguity, while current source-owned ambiguity never infers provider outcome from transient job state. Aborted or failed predecessors and exhausted admission attempts remain visible terminal rows. Transport-ambiguous enqueue outcomes stay non-resendable until exact request-identity reconciliation succeeds; an elapsed client observation window may hide the warning locally but never converts ambiguity into permission to submit again. Conversation deletion cancels the rows, retires their deliveries, and removes their payloads before deleting the conversation wave. +- **Subagent activity stream**: an observational, task-scoped live projection of bounded child progress for the currently open private panel. It may cross API replicas through Redis, never carries hidden reasoning text, and never controls or settles execution. The durable child thread remains canonical and its existing polling view is the fallback for missed or unavailable live events. +- **Agent event handling outcome**: the durable, generation-fenced result of a previously accepted event delivery. `started` proves generation admission; terminal states distinguish verified tool application, clean completion without action, failure, and cancellation. Transport success remains separate so an accepted event cannot masquerade as completed work. +- **Agent event expected action**: an optional source-declared tool name and bounded argument subset evaluated against host-observed completed run steps. It is evidence policy, not authorization and not a model-authored success claim. +- **Event actor head**: the private, durable pointer on an event-bound child conversation to its latest committed LangGraph checkpoint, plus one previous checkpoint for safe cleanup. Only a qualifying applied action advances it through compare-and-swap; failed, cancelled, or no-action invocations leave it unchanged. A legacy-path event marks the head for a cold rebuild from durable message history before fork mode can resume. Every applied commit conflict, unverified commit, or post-commit persistence failure is retained in a private reconciliation journal that blocks later actor turns instead of continuing from stale state; an exact marker can be cleared only after its checkpoint is verified authoritative, its history is repaired, or its external action is explicitly compensated. +- **Event actor invocation fork**: a delivery-owned checkpoint namespace copied from the event actor head. Every bound Event Actor enters one turn module; `fresh`, `history`, and `checkpoint` are internal state-loading adapters selected automatically from actor state and immutable request capability, never from operator configuration. The history adapter owns its durable turn fence and token ordering, while immutable protocol-v1 tokens remain read-compatible until their jobs drain. A warm invocation receives only the new trusted event, then commits its terminal checkpoint when the expected action is observed or deletes the fork otherwise. When the invocation pauses for approval or Ask User, the SDK emits signed, versioned suspension evidence. The child Conversation is the canonical one-shot suspension authority; the generation job carries only a versioned projection for UI, rolling-deploy routing, and the existing resume endpoint. Current Event Actor hosts select generation protocol v2 automatically; a trusted pre-capability producer remains on history only for the mixed-version drain. A resume shares one identity between its Conversation claim and provider-owner CAS, clears the predecessor projection, and publishes a successor only after a re-pause is canonical. A pending interrupt takes precedence over expected-action evidence from the same segment; if that segment already applied the expected action, publishing its successor pause cold-marks the prior head until a later applied commit replaces it. An ambiguous projection write is accepted only after reading back the exact generation, action, and suspension. The provider-start CAS is written only after client reconstruction and immediately before the continuation gate opens, then retains its exact execution identity after drain, so terminal recovery can compensate a projected claim only when that identity proves execution never began. Durable approval projection is exposed before the persistence barrier opens, preventing a resolved action from being announced afterward. Terminal no-action retirement cancels or settles the exact suspension and releases its delivery-side action admission before public settlement; if retention already removed the child Conversation, the delivery remains authoritative for its exact admission identity. Resume, re-pause, cancellation, and expiry claim or replace that exact suspension before touching its job projection, so later mailbox deliveries stay blocked until terminal history and handling evidence settle. +- **Event actor receipt**: the private, terminal proof stored on the authoritative `AgentTriggerDelivery` row for one bound actor invocation. Its unique delivery identity, terminal resolution, exact checkpoint, and bounded action identity provide replay and recovery for the retention window without storing prompts, events, tool arguments, tool output, or conversation history. It does not own the actor checkpoint; the conversation keeps only the actor head and any active unresolved reconciliation until this receipt is durable. +- **Agent event actor mailbox**: the automatic durable delivery-ordering lane for one authenticated source binding. It keeps later deliveries queued after transport admission until the current child turn records an authoritative terminal handling outcome. It serializes existing coalesced batches and individual events without becoming a second execution controller or actor checkpoint store. +- **Agent trigger capability shield**: the durable mixed-version representation for internal trigger work that only a capability-aware worker may execute. Mongo uses an old-publishable `staging` shell; a queued `leased` shell without an owner or deadline, which old workers cannot claim but can use for bounded lane rechecks; a private lease only during execution; and a legacy-terminal `capability_dead` shell once dead. Private capability fields own current claiming, retry, and dead-letter truth. Redis uses a versioned fail-closed terminal status and recovery index that old replacement scripts and sweepers cannot consume.

Explicit `0` keeps per-delta +publication; existing explicit values retain their behavior. In-memory streams +are unchanged, including deployments using `USE_REDIS_STREAMS=false`. + +The same window batches durable appends and publications. It reduces Redis +round trips and repeated guard/TTL work, but not Pub/Sub message count at the cost of up to one window of buffering latency and possible loss +of unflushed deltas on process crash. Terminal and non-coalescable barriers still +flush pending batches before proceeding. + +Coalescing batches Redis requests, not the subscriber wire format: each event +still publishes as an individually sequenced `chunk` frame. Subscribers from +before batch-frame support can read these publications without a preparatory +configuration change. New subscribers also retain `chunk_batch` decoding for +interoperation with existing opt-in batching producers. + +This removes the new default's batch-frame compatibility hazard; it does not +promise compatibility across unrelated generation-protocol changes. If an +existing producer already emits `chunk_batch` frames through explicit opt-in, +keep those producers away from subscribers that predate batch-frame support, +or disable coalescing on those producers before introducing older subscribers. + +## Tenant index migration (v0.8.7 and earlier databases) + +Upgrading an existing database can log `Index build failed` for User, Role, +Preset, AccessRole, MCPServer, AgentCategory, Message, or Conversation. Older +unique indexes (for example `email_1` or `name_1`) conflict with current non-unique +indexes of the same name. Tenant-scoped compound indexes now enforce uniqueness. +This also affects single-tenant deployments. See #15759 (successor to #14826). + +The tenant-index migration is an explicit maintenance command; startup does not +run it automatically. Use the updated code/image containing this command. For a +source checkout, install dependencies and build the packages first (`npm run +build:packages`). + +1. Back up MongoDB and stop all LibreChat API replicas and workers that write to + the database. Keep MongoDB available throughout the migration. +2. Preview known legacy unique indexes using the deployment's `MONGO_URI` and + connection settings from `.env`: + + ```sh + npm run migrate:tenant-indexes:dry-run + ``` + +3. Apply the migration: + + ```sh + npm run migrate:tenant-indexes + ``` + + With Docker Compose, stop the API and run a one-off container from the updated + image while MongoDB remains running. Use the same Compose file flags as your + deployment (for example, `docker compose -f deploy-compose.yml`). Set the + working directory to `/app`, where the root npm scripts live; the production + API image otherwise defaults to `/app/api`: + + ```sh + docker compose stop api + docker compose run --rm --no-deps -w /app api npm run migrate:tenant-indexes:dry-run + docker compose run --rm --no-deps -w /app api npm run migrate:tenant-indexes + docker compose up -d api + ``` + +4. Restart writers only after the command exits successfully (status 0). Verify + that startup no longer reports these index conflicts. + +The command first builds tenant-scoped unique indexes, then drops only known +superseded unique indexes, and explicitly creates current schema indexes for the +affected collections. It preserves custom indexes and current non-unique indexes; +it does not delete documents or use `syncIndexes`/`dropIndexes`. Automatic index +creation is disabled in the maintenance process to prevent races, even when the +server normally enables it. Current indexes are explicitly built even if the +server uses `MONGO_AUTO_INDEX=false`. + +The dry run only lists removals: it does not validate replacement builds, database +permissions, or duplicate data. Any listing, dropping, or building error makes +the apply command fail. If replacement creation fails (for example due to +existing duplicates or unsupported database index options), no old constraints +have been dropped. Keep writers stopped, correct the reported problem, and rerun. +A later failure can leave a partial migration; rerunning safely completes it. +Index builds may take time on large collections. Do not drop all indexes to +resolve a failure. diff --git a/api/app/clients/BaseClient.js b/api/app/clients/BaseClient.js index b7c5a8ae59d..4a4f6975bda 100644 --- a/api/app/clients/BaseClient.js +++ b/api/app/clients/BaseClient.js @@ -9,51 +9,101 @@ const { sanitizeFileForTransmit, extractFileContext, getReferencedQuotes, + applyTurnDelivery, encodeAndFormatAudios, encodeAndFormatVideos, + getTransactionsConfig, encodeAndFormatDocuments, + getLangfuseTraceMessageFields, + isContentFilterError, + assertModelBoundProviderContent, + reportLocatorTraversalFailure, + collectModelBoundHistoricalFileIdState, + projectModelBoundSourceFiles, + isModelBoundAttachmentFile, + isToolOwnedAttachment, + withBalanceReservations, + findCheckpointSummaryPart, + getSummaryPartText, + runAfterSeed, + saveTurnConversation, + seedTurnConversation, + needsRetentionConversation, + getConversationWriteContext, } = require('@librechat/api'); const { Constants, FileSources, Tools, + ErrorTypes, ContentTypes, - excludedKeys, + isCompactedLeaf, EModelEndpoint, - mergeFileConfig, isParamEndpoint, isAgentsEndpoint, - isEphemeralAgentId, supportsBalanceCheck, isBedrockDocumentType, - getEndpointFileConfig, + HITL_MESSAGE_FILTER_FIELDS, + stripReasoningLabelMetadata, + resolveTurnLLMDeliveryPath, + resolveUseResponsesApi, } = require('librechat-data-provider'); const { getStrategyFunctions } = require('~/server/services/Files/strategies'); const { logViolation } = require('~/cache'); const TextStream = require('./TextStream'); const db = require('~/models'); -const collectHistoricalFileRefs = (message) => { - const refs = []; - if (Array.isArray(message.files)) { - refs.push(...message.files); - } - if (Array.isArray(message.attachments)) { - refs.push(...message.attachments); - } - return refs; -}; - -const collectHistoricalFileIds = (messages) => { - const fileIds = new Set(); - for (const message of messages) { - for (const ref of collectHistoricalFileRefs(message)) { - if (ref?.file_id) { - fileIds.add(ref.file_id); - } +const omitUnreplayedHistoricalFiles = (messages) => + messages.map(({ files: _files, attachments: _attachments, ...message }) => ({ + ...message, + ...(Array.isArray(message.content) + ? { + content: message.content.map((part) => { + if (part == null || typeof part !== 'object') { + return part; + } + const { + file: _partFile, + files: _partFiles, + image_file: _imageFile, + file_id: _fileId, + ...rest + } = part; + return rest; + }), + } + : {}), + })); + +const mergeUserSubmittedPaths = (...pathLists) => [ + ...new Set( + pathLists + .flat() + .filter((path) => typeof path === 'string' && path.startsWith('/') && path.length <= 2048), + ), +]; +const hitlMessageFilterFields = new Set(HITL_MESSAGE_FILTER_FIELDS); +const mergeUserSubmittedMessageFieldPaths = (...entryLists) => { + const entries = []; + const seen = new Set(); + for (const entry of entryLists.flat()) { + if ( + entry == null || + typeof entry.path !== 'string' || + !entry.path.startsWith('/') || + entry.path.length > 2048 || + !hitlMessageFilterFields.has(entry.field) + ) { + continue; + } + const key = `${entry.field}:${entry.path}`; + if (seen.has(key)) { + continue; } + seen.add(key); + entries.push(entry); } - return Array.from(fileIds); + return entries; }; const buildOwnerFileFilter = (fileIds, user) => { @@ -71,6 +121,14 @@ const buildOwnerFileFilter = (fileIds, user) => { return filter; }; +const getOwnerHistoricalFiles = async (fileIds, user) => { + const fileFilter = buildOwnerFileFilter(fileIds, user); + if (!fileFilter) { + return []; + } + return (await db.getFiles(fileFilter, {}, {})) ??

The current +progressive-row strategy optimizes the first commit but deliberately converges +to the complete DOM.

Each run starts a disposable MongoDB and the real Express +server, registers a local user, and seeds a conversation. No model inference is needed. +Do not point this test at a deployed service. Playwright refuses to reuse an existing +server. + +The existing `benchmarks/mongoose-latency-hook.cjs` adds **250 ms per Mongoose +Query/Aggregate execution** in the server process. Independent queries can overlap; +serial queries compound. This is a deterministic approximation of remote database +latency, not a replica topology or network emulator. It also delays query-based +writes; native driver calls, bulk operations and cursor batches are outside its +coverage. Use a TCP latency proxy if those paths need coverage. + +The runner makes three cold browser navigations to a populated conversation, +using the production client build and real authentication, config, file and message +routes. It uses desktop settings with `throttlingMethod: provided` so Lighthouse +does not replace the measured server delays with simulated network timing. +Median budgets are LCP **4,500 ms**, CLS **0.1**, and TBT **500 ms**, asserted against +the median of the three runs.

The database delay hook can be preloaded by that fixture's server +configuration. Keep provider-specific authentication and provisioning in that spec. +For launch flows that navigate across documents, also measure entry-to-ready time +with Playwright: LCP resets on a new document, so final-page LCP alone does not +cover the entire launch.

This is optional and is disabled unless you +explicitly deploy the fanout gateway. + +The deployment is a hybrid: + +- the Go gateway is the only endpoint LibreChat talks to; +- trace requests are proxied to an internal OpenTelemetry collector; +- the collector owns trace memory limiting, batching, routing, and export; +- the Go gateway owns Langfuse media create/upload/patch fanout. + +## How It Works + +- Agent traces use Langfuse OTLP ingestion. +- LibreChat sends tenant traces to the local fanout gateway when + `LANGFUSE_FANOUT_ENABLED=true` and `LANGFUSE_FANOUT_COLLECTOR_URL` points at + the fanout gateway. +- The gateway forwards trace requests to the internal OpenTelemetry collector + at `LANGFUSE_FANOUT_TRACE_COLLECTOR_URL`. +- The collector exports every trace to the central Langfuse project using + `LANGFUSE_FANOUT_CENTRAL_AUTH_HEADER`. This prebuilt header is collector-only; + the LibreChat app derives central score auth from `LANGFUSE_PUBLIC_KEY` and + `LANGFUSE_SECRET_KEY`. +- The collector also exports tenant-enabled traces to the tenant Langfuse + project by routing on `librechat.langfuse.destination`, then forwarding the + tenant `Authorization` header that LibreChat attaches to the OTLP request. +- For tenant-exportable runs, LibreChat uses a destination-scoped gateway URL + like `http://langfuse-fanout-collector:4318/tenant/us`. Langfuse media upload + requests do not carry span attributes, so this path gives the gateway the + destination needed to copy media into the tenant's Langfuse region. For + traces on this path, the gateway restores the internal tenant routing + attributes before handing the request to the collector. +- Before export, the collector deletes the internal `librechat.langfuse.*` + routing attributes from central and tenant traces. +- Langfuse media upload is fanned out by calling `POST /api/public/media` on + central and tenant Langfuse, returning a one-time gateway upload URL, then + uploading the received bytes to each upstream presigned upload URL. The SDK's + `PATCH /api/public/media/{mediaId}` status call is also fanned out. +- Central media export can be disabled independently of central trace export + with `LANGFUSE_FANOUT_CENTRAL_MEDIA_EXPORT_DISABLED=true`. Per-run central + trace suppression uses a destination-scoped gateway path that also skips + central media export for that run. +- Tenant export is conditional. LibreChat uses a destination-scoped gateway URL + only when the saved connection is enabled with tenant keys, its destination + key matches a configured startup destination, and + `LANGFUSE_FANOUT_TENANT_EXPORT_DISABLED` is not true. + Other traces are still exported to central through the gateway without tenant + auth. +- User feedback scores use Langfuse's direct REST API from the LibreChat API + process. Central scores use LibreChat's normal central Langfuse env config; + tenant scores use tenant app configuration when tenant fanout is enabled. + +Tenant Langfuse keys are expected to come from LibreChat app configuration. +When available, an authorized administrator can configure and verify the +connection under **Settings > Langfuse**; LibreChat encrypts the secret key at +rest. The keys are not defined in this gateway config. + +## Limitations + +- Langfuse base URLs are startup configuration. `LANGFUSE_FANOUT_CENTRAL_BASE_URL` + and `LANGFUSE_FANOUT_TENANT_DESTINATIONS` must be known when LibreChat and the + gateway start. Tenant app configuration may choose any configured tenant + destination. +- Tenant Langfuse API keys can be added, changed, or disabled in tenant app + configuration at runtime without restarting LibreChat or the gateway. +- Tenant app configuration must select a destination key from + `LANGFUSE_FANOUT_TENANT_DESTINATIONS` before tenant trace/score export is + enabled; keys alone do not enable tenant export. +- `LANGFUSE_FANOUT_TENANT_EXPORT_DISABLED=true` can be set on LibreChat as an + emergency switch to stop tenant trace and score export while keeping central + gateway export active. When omitted, false, or blank, tenant export remains + available if tenant keys and a known destination are configured. +- `LANGFUSE_FANOUT_CENTRAL_MEDIA_EXPORT_DISABLED=true` can be set on the gateway + to stop central media create/upload/patch fanout while leaving central trace + export unchanged. +- This supports Langfuse Cloud and self-hosted Langfuse as long as each allowed + tenant base URL is configured at LibreChat/gateway startup. Runtime tenant + config selects from those known destinations; it does not inject arbitrary + export URLs into the gateway. +- The provided Compose gateway config is a three-region Langfuse Cloud preset + (`eu`, `us`, `jp`). Compose's static collector config routes only those keys; + the gateway fails startup when `LANGFUSE_FANOUT_TENANT_DESTINATIONS` contains + a key outside `LANGFUSE_FANOUT_TRACE_DESTINATION_KEYS`. For self-hosted or + additional destination keys, update the collector config too or use Helm. +- Helm binds the internal collector receiver to `127.0.0.1:4319` because the + collector is a sidecar. Compose binds it to `0.0.0.0:4319` on the private + `langfuse-fanout` network. Do not publish the internal collector receiver + outside the fanout deployment; tenant routing validation happens in the + gateway before traces reach the collector. +- The gateway stores short-lived one-time media upload plans in Redis. This lets + media create and byte-upload requests land on different gateway replicas. + Compose includes a private Redis container; Helm can derive the URI from the + bundled Redis chart or use an explicit `langfuseFanout.redis.uri`. +- The gateway requires an explicit public/internal base URL for one-time upload + URLs. Compose sets `LANGFUSE_FANOUT_PUBLIC_URL` to its private gateway + service URL. Helm derives the fanout Service DNS name unless `publicUrl` is + set. +- Media fanout is not transactional across central and tenant projects. If one + destination accepts `POST /api/public/media` and another fails, LibreChat sees + a gateway error and will not upload bytes, but the successful destination may + retain a short-lived, unused media record. +- Trace batching is handled by the collector. By default it flushes after 128 + items or 1 second, and tenant batches are separated by the request + `Authorization` metadata. +- The gateway exposes Prometheus metrics at `/metrics` using the same bearer + token shape as LibreChat.

The Service exposes +only the gateway. The chart also injects `LANGFUSE_FANOUT_ENABLED` plus +`LANGFUSE_FANOUT_COLLECTOR_URL` into the LibreChat app ConfigMap when they are +not already supplied in `librechat.configEnv`. + +Set `langfuseFanout.redis.uri` when using an external Redis service. If Redis +requires auth, set `langfuseFanout.redis.username` and point +`langfuseFanout.redis.passwordSecret.name`/`.key` at an existing Kubernetes +Secret. When using the bundled Redis chart with auth enabled, create a password +Secret for the gateway or provide an explicit authenticated URI. +Prefer `passwordSecret` over embedding credentials in `redis.uri`, because the +URI is rendered directly into the Deployment environment. +Scale the gateway manually with `langfuseFanout.replicaCount`; the chart does +not create a fanout HPA. The gateway container has configurable `/healthz` +liveness and readiness probes under `langfuseFanout`. + +Useful gateway metrics include: + +- `langfuse_fanout_http_requests_total` +- `langfuse_fanout_upstream_requests_total` +- `langfuse_fanout_trace_exports_total` (`destination`, `result`, and `tenant_id` labels) +- `langfuse_fanout_media_upload_plans_created_total` +- `langfuse_fanout_media_upload_plans_completed_total` +- `langfuse_fanout_media_upload_plan_misses_total` +- `langfuse_fanout_media_upload_plan_store_errors_total` +- `langfuse_fanout_media_upload_bytes` +- `langfuse_fanout_media_divergence_total` + +LibreChat stamps `librechat.tenant.id`, `librechat.langfuse.export_plan`, and +`librechat.langfuse.export_reason` on Langfuse run spans. The gateway reads the +tenant ID from each OTLP batch for the trace export counter. Batches without a +tenant ID use `<unknown>`; batches containing more than one tenant use `<multiple>`. +Invalid tenant IDs use `<invalid>`. The gateway retains up to 1,000 valid tenant +labels and aggregates additional IDs under `<overflow>`, bounding the trace +counter's cardinality. Angle brackets keep these synthetic values outside +LibreChat's accepted tenant-ID grammar. + +Successful admin connection updates emit the structured log event +`librechat.langfuse.connection.changed`. It includes the tenant, configuration +state, destination, verification result, a primary `change`, and all `changes`. +It does not include the Langfuse public or secret key. + +`langfuse_fanout_media_divergence_total{kind="media_id"}` is the correctness +signal for trace/media token fanout. `kind="upload_url_presence"` records that +some destinations returned an upload URL while others treated the media as +already uploaded. + +## Notes + +- The gateway handles Langfuse media uploads and proxies traces to the internal + collector. Feedback scores go directly to Langfuse's REST API from the + LibreChat API process. +- `LANGFUSE_FANOUT_CENTRAL_AUTH_HEADER` must be a full Basic auth header and is + consumed by the fanout deployment only. The app does not use it for scores. +- `LANGFUSE_FANOUT_CENTRAL_BASE_URL` is also consumed by the fanout deployment only. + For non-EU central feedback scores, set LibreChat's normal `LANGFUSE_BASE_URL` + to the same central Langfuse region. +- Tenant destinations default to the three configured Langfuse Cloud regions. Add or + override `langfuseFanout.tenant.destinations` in Helm for self-hosted or + custom destinations. +- `LANGFUSE_FANOUT_LISTEN_ADDR` controls the gateway HTTP bind address and + defaults to `:4318`. +- `LANGFUSE_FANOUT_UPSTREAM_TIMEOUT` tunes the timeout for gateway calls to + Langfuse APIs and presigned media upload URLs. +- `LANGFUSE_FANOUT_PUBLIC_URL` pins the base URL returned for the SDK's + one-time media upload. The gateway fails startup when it is unset or invalid; + this avoids trusting request `Host` or `X-Forwarded-Host` headers. +- `LANGFUSE_FANOUT_TRACE_DESTINATION_KEYS` is a startup guard that must contain + every key in `LANGFUSE_FANOUT_TENANT_DESTINATIONS`; this prevents media + fanout from accepting a destination the collector cannot route traces to. +- `LANGFUSE_FANOUT_REDIS_URI`, optional `LANGFUSE_FANOUT_REDIS_USERNAME`, + optional `LANGFUSE_FANOUT_REDIS_PASSWORD`, and + `LANGFUSE_FANOUT_REDIS_KEY_PREFIX` configure the shared one-time media upload + plan store. The gateway fails startup without a Redis URI. +- `LANGFUSE_FANOUT_OTEL_RECEIVER_ENDPOINT` controls the internal collector + receiver bind address. +- `LANGFUSE_FANOUT_METRICS_SECRET` protects the gateway `/metrics` endpoint. + If unset, the gateway falls back to `METRICS_SECRET` when present. +- `LANGFUSE_FANOUT_MEMORY_LIMIT_MIB`, + `LANGFUSE_FANOUT_MEMORY_SPIKE_LIMIT_MIB`, `LANGFUSE_FANOUT_BATCH_TIMEOUT`, + `LANGFUSE_FANOUT_BATCH_SEND_SIZE`, and + `LANGFUSE_FANOUT_METADATA_CARDINALITY_LIMIT` tune the internal collector. +- `LANGFUSE_FANOUT_COLLECTOR_URL` is the local gateway URL used by LibreChat. + The env name is kept for compatibility with the original collector shape; it + is not a Langfuse Cloud base URL. diff --git

The model retrieves it via the + * `check_background_task` poll tool. No `@librechat/agents` change is required — + * a backgrounded call and the poll call are both synchronous from the graph's + * view. + * + * Scope: execution remains owned by one Node process, independently of the + * dispatch turn's abort signal. The host gives the detached invoke a separate + * deadline signal and accepts a timeout only after the invoke settles; an + * abort-resistant tool remains indeterminate and pollable. Terminal results + * can also be persisted onto the invoking response so another run or replica + * can consume them, but process death during execution does not recreate the + * live tool. Ephemeral request-scoped MCP tools (runtime `{{LIBRECHAT_BODY_*}}` + * placeholders) are never backgrounded — their connection is torn down at + * request end, so the executor runs them in the foreground instead. Detached + * subagents use the separate host task store; Redis-backed hosts may route + * their poll/control operations to the owning process without moving the live + * executor or making ordinary background tool results durable. + * + * Opt-in mirrors `deferred_tools`: an admin capability + * (`AgentCapabilities.run_in_background`) gates the feature, and a per-tool + * `tool_options[name].run_in_background` flag turns it on for a given tool, + * which injects a `run_in_background` boolean into that tool's schema.

An interrupt records an `INTERRUPT` ("__interrupt__") + * write; a delta-channel graph records its delta writes on a real (non-`__`-prefixed) channel. + * A CLEAN exit produces a checkpoint with NO pending writes. So we record the checkpoint id of + * each `putWrites` that carries a {@link hasResumableWrite resumable} write and persist a `put` + * only when its `checkpoint.id` was so marked — which keeps interrupt checkpoints AND any + * real-channel/delta anchors (resume can walk the chain), while dropping the write-less clean + * exit. Keying on the globally-unique checkpoint id (NOT thread_id) stays correct even when two + * runs race on the same conversation (`thread_id`). + * + * **Bookkeeping batches follow their checkpoint's fate.** Only a {@link hasResumableWrite + * resumable} batch ANCHORS a checkpoint (justifies persisting it); a bookkeeping-only batch + * (`__error__`, `__no_writes__`, a lone `__resume__`, …) never does — but whether its ROWS matter + * depends on whether the checkpoint survives, which `put` decides later. Probe-confirmed both + * ways: a failed non-paused turn emits `putWrites([__error__])` + `put` — persisting either half + * would leak (an orphan row or a dead checkpoint) — while a paused Send fan-out records completed + * siblings as `__no_writes__` markers on the RETAINED interrupt checkpoint, and dropping those + * re-executes the siblings on resume (duplicated side effects). So bookkeeping batches are + * BUFFERED in memory until the fate is known: forwarded once the checkpoint is anchored (or was + * just persisted), dropped when its `put` discards it. Net effect: an errored turn still leaves + * NOTHING durable (0 checkpoints, 0 write rows), and a retained checkpoint keeps EVERY pending + * write LangGraph recorded for it — byte-for-byte what a plain `MongoDBSaver` would store. + * + * For LibreChat's agent graph (standard `Annotation`/`MessagesAnnotation` channels, no + * `DeltaChannel` — grep-confirmed in `@librechat/agents`) a clean run makes no `putWrites` at all, + * so this is effectively interrupt-only and the common path writes nothing; the broader + * real-channel rule just keeps it honest for delta graphs. + * + * **Invariant.** Correctness depends on `durability: 'exit'` (which the SDK sets whenever a + * checkpointer is active): exactly one parentless boundary checkpoint per run, with its + * `putWrites` ordered before its `put`. Under per-step durability LangGraph instead emits + * `put`-before-`putWrites` for chained checkpoints — the anchor would arrive too late and a + * checkpoint could be wrongly discarded. The SDK never runs HITL that way; if that ever changes, + * this saver must be revisited (a parent-based guard is NOT viable — a resumed turn's clean + * completion is itself a parented, write-less checkpoint that we correctly discard). + * + * **Correctness.** Checkpoints with resumable writes (interrupt + real-channel/delta anchor) and + * the writes themselves persist exactly as before, so resume is unchanged. The write-less clean + * checkpoint (and the now-discarded error-only checkpoint) was only ever written-then-pruned, so + * not writing it is observationally equivalent; the pre-run prune + Mongo TTL remain the + * backstops.

The service's content handlers also share text, reasoning and usage handling between modes. The controller retains its existing run lifecycle, usage recording, artifact writes and authorization boundaries. + +## Identity + +- A declaring run step owns call identity. Optional provider IDs are aliases, not a prerequisite. Declaration slots keep id-less calls distinct and make snapshot replay idempotent. Provider IDs can repeat in later steps and are not completion-wide identities. +- Outward indexes are allocated once per call across the response. Raw ID substrings are assembled by provider index; shared prefixes such as `call_` are never cross-call aliases. Calls without IDs receive `call_<index>`; collisions receive a suffix. Internal tool execution IDs are not rewritten. +- Argument fragments use provider indexes scoped to a model invocation. A graph delta may name the latest step while referring to an earlier parallel call. When available, the SDK's `getStepBaseKey` supplies invocation scope, including stream segments. A step's scope is retained so late fragments cannot acquire a newer segment's identity. +- Callers without the graph object use metadata scope; callers without that metadata are isolated by step. This fallback cannot reconstruct a missing retry/segment identity. +- Explicit and identified provider indexes take precedence over positional fallback. Positions are used only for multi-call declarations. An unbound singleton may adopt its first provider index; it does not absorb arbitrary later indexes. + +## Argument representations + +A run-step declaration can contain a **snapshot**: native `args` or OpenAI-shaped `function.arguments`. A run-step delta carries an **append-only fragment**. They must never be concatenated as though they were the same representation. + +Both snapshot argument fields accept JSON **strings or objects**, using the shared `Agents.ToolCall` and `Agents.AgentFunctionToolCall` field types. Strings are retained verbatim; objects are serialized once. Nonempty argument fragments take precedence over all snapshots for that call, regardless of arrival order. + +### Publication timing + +Tool-call IDs and names can also arrive as substrings. There is no per-field completion seal in these events, and the OpenAI-compatible consumer freezes the name on its first chunk. Emitting `get_` and later correcting it to `get_weather` does not work. + +Consequently, **tool-call chunks are published only at successful response completion**, after assembling identity and validating arguments. The first chunk contains the complete ID/name; the next carries the complete arguments at the same index. Text and reasoning continue streaming while the run executes. This deliberately sacrifices incremental tool-input display, rather than guessing which names are complete or breaking existing clients. Native JSON responses receive the same completed calls. + +Name/ID/argument fragments are append-only and take precedence over the corresponding declaration snapshot. Snapshot replay is idempotent; raw fragments are not deduplicated because identical adjacent fragments can be legitimate and the events carry no sequence token. Split IDs require a provider index for unambiguous correlation. Exactly-once raw dispatch remains an upstream requirement. + +## Terminal behavior + +`completeOpenAIToolCalls` wraps execution and owns the success/failure boundary. The controller schedules completed-run usage recording before final validation. + +| State/event | Behavior | +| ---------------------------------------- | ---------------------------------------------------------------- | +| Open + declaration | Allocate identity once; retain snapshot separately | +| Open + identified fragment | Bind provider index and append/buffer fragment | +| Successful execution | Assemble and validate all calls before publishing tool chunks | +| Failure, abort or invalid terminal input | Discard pending calls; publish no tool-call chunks | +| Finished | Repeated finish is harmless; later tool events are ignored | +| Aborted | Later tool events are ignored; finish cannot reopen the response | + +Missing names, missing arguments, malformed JSON or unattributable argument data fail terminal projection with bounded errors that omit provider content. A snapshot never repairs a truncated raw stream. Projection bookkeeping is response-local and released on finish/abort; only successfully validated calls are materialized for the response builder. Publication seals before calling the transport, so a transport error or reentrant finish cannot duplicate calls. Already transmitted frames cannot be retracted. + +The existing finish-reason policy is preserved: a response with final text after server-executed tools remains `stop`. Historical tool calls are still exposed by this API. This patch does not make it safe to interpret every advertised call as a new instruction for the caller to execute. + +## Verification and limits + +- `toolCalls.contract.spec.ts`: shared field types, strings/objects, partial names and IDs, optional IDs, declaration order and transport reentrancy. +- `toolCalls.spec.ts`: identity, representations, ordering, replay, malformed input, failure and abort. +- `toolCalls.graph.spec.ts`: real SDK interleaving, complete-only chunks and stream segments. +- `service.spec.ts` and the Express controller spec: both response modes, actual serializers, fallback flush and failure/usage ordering. + +These tests do not run a live provider, real tool side effects, a distributed multi-agent deployment or a persisted resume.

Remote callers do not choose `event.source`; provider-specific webhook +adapters may verify their native signature and map verified provider metadata into the trusted +in-process adapter contract above. + +```http +POST /api/agents/v1/events +Authorization: Bearer <remote-agents-api-key> +Idempotency-Key: webhook-42-resource-7 +Content-Type: application/json + +{ + "mode": "fire", + "event": { + "id": "resource-7-ready-3", + "type": "resource.ready", + "occurredAt": 1786967999000, + "payload": { "resourceId": "resource-7" } + }, + "target": { "agentId": "agent-id" }, + "input": "Resource resource-7 is ready. Inspect it and report the result.", + "orderingKey": "resource-7" +} +``` + +A successful admission returns `202 Accepted`, an opaque delivery `id`, and a `Location` header. +Poll that location to read `pending`, `leased`, `succeeded`, or `dead` state. Successful fire +results include the conversation and generation identity needed for a later `steer` event. Status +responses never expose the stored source payload, ordering key, retry history, or worker identity. +Callers must sanitize `event.payload`; credentials and transport secrets must not be persisted. + +For a bound `continue`, `succeeded` means generation admission succeeded, not that the requested +work finished. The status response therefore also exposes a durable `handling` lifecycle: +`started`, followed by exactly one of `applied`, `completed_no_action`, `failed`, or `cancelled`. +Action-aware bound-child sources may send an `expectedAction` containing a tool name and optional +argument subset. LibreChat reports `applied` only when the exact generation completes with +host-observed tool evidence matching that contract; model-authored prose is never accepted as +proof. Fire, steer, and unbound continue deliveries reject this contract. + +### Event-driven child actors + +Register a direct child agent once under the same Remote Agents API key that will deliver events. +The parent must be an ordinary agent conversation, and the target must be enabled in that parent +agent's direct `subagents.agent_ids` list (or be an allowed self-spawn). The reserved child +conversation is hidden from conversation lists and remains read-only to human chat routes. +Bound child continuations are automatic after authentication and binding authorization. +`AGENT_TRIGGERS_SELF_URL` remains a compatibility fallback for +`endpoints.agents.eventDriven.selfUrl`; most deployments should omit both and use the bound +listener. + +Detached Event Actor completion is automatic for every built-in generation store. The in-memory +adapter preserves the lifecycle while its process remains alive; Redis adds restart recovery and +replica handoff without changing the Event Actor interface. +Completion work is stored behind a mixed-version compatibility shield: older replicas retain lane +and account-deletion safety but cannot claim, recover, requeue, or interpret the new work. Internal +detached completions always target the capable worker's bound listener; +`AGENT_TRIGGERS_SELF_URL` remains available for ordinary trigger dispatch but cannot route +capability-owned completion work to another replica. + +```http +POST /api/agents/v1/events/bindings +Authorization: Bearer <remote-agents-api-key> +Idempotency-Key: championship-7-player-hanae +Content-Type: application/json + +{ + "actorId": "hanae-kobayashi", + "parentConversationId": "director-conversation-id", + "parentMessageId": "director-message-id", + "target": { "agentId": "agent-hanae" } +} +``` + +The response contains an opaque `id` and the child `threadId`. Store the binding id with the +source actor. Deliver every later turn with a source-stable event id and the same API key: + +```http +POST /api/agents/v1/events +Authorization: Bearer <remote-agents-api-key> +Idempotency-Key: game-12-ply-17-hanae +Content-Type: application/json + +{ + "mode": "continue", + "bindingId": "evtbind_…", + "event": { + "id": "game-12-ply-17", + "type": "chess.turn.ready", + "occurredAt": 1786968000000, + "source": { "id": "speed-chess", "type": "mcp" }, + "payload": { "gameId": "game-12", "expectedPly": 17 } + }, + "input": "Your clock is running. Read the position and submit one legal move." +} +``` + +LibreChat resolves the bound agent and child conversation from `(user, tenant, API key, binding)`; +caller-supplied target fields are discarded. It also resolves the latest assistant branch leaf +immediately before dispatch, so queued events do not persist stale chat topology. Each actor binding +is its default ordering lane. A short-lived internal trigger token plus a second binding lookup is +required to pass the child-thread write guard; possessing a binding id alone grants no access. + +The actor mailbox is automatic for bound continuations. A bound actor's next delivery stays queued +after the current delivery reaches transport success and does not dispatch until that child +generation records `applied`, +`completed_no_action`, `failed`, or `cancelled`. Different bindings remain independent and can run +in parallel. Existing coalesced batches occupy one mailbox position and retain each member's +individual receipt. An active mailbox record does not receive its normal success TTL; the 90-day +retention window begins only after terminal handling is recorded. + +Durable receipts and token-fenced action admission are automatic for bound events with an expected +action. Checkpoint continuation is attempted only when the initialized turn is compatible. A +missing or unrestorable checkpoint falls back to durable message history without weakening the +receipt, authorization, or expected-action fences. + +### Coalescing observational child events + +Sources that can prove several bound `continue` events are interchangeable observations may opt +those deliveries into one bounded child turn. Add the same source-defined compatibility key to each +compatible request: + +```json +{ + "mode": "continue", + "bindingId": "evtbind_…", + "event": { + "id": "championship-7-game-12-move-18", + "type": "chess.move.completed", + "occurredAt": 1786968000750, + "payload": { "gameId": "game-12", "ply": 18 } + }, + "input": "A tournament game advanced.", + "coalesce": { "key": "championship-commentary" } +} +``` + +LibreChat collects compatible events for up to 750 ms, with a maximum of 8 events and 512 KiB of +combined envelopes. It invokes the child once with a deterministic JSON document whose +`kind` is `librechat.agent_event_batch`; the document contains every event, source input, delivery +identity, and a count by event type. Each source event still requires its own stable +`Idempotency-Key`, durable delivery record, and status receipt. Retrying one event cannot duplicate +the batch or create another branch. + +Coalescing is intentionally accepted only for authenticated bound-child `continue` deliveries. +The source must not set `coalesce` for a player turn, command, fence, approval, HITL request, or any +event whose individual timing or acknowledgment is actionable. `fire`, `steer`, and unbound +`continue` deliveries reject the option instead of silently weakening their semantics. Deliveries +with `expectedAction` also reject coalescing because one generation cannot prove several distinct +action fences. diff --git a/packages/api/src/agents/triggers/actor.spec.ts b/packages/api/src/agents/triggers/actor.spec.ts new file mode 100644 index 00000000000..c2d5fade69d --- /dev/null +++ b/packages/api/src/agents/triggers/actor.spec.ts @@ -0,0 +1,1820 @@ +import type { + IAgentEventActorReconciliation, + IAgentEventActorState, + IAgentEventActorSuspension, +} from '@librechat/data-schemas';

It does not borrow a browser session +or replace a live interactive connection. Graph agents are loaded in breadth-first +batches, and private children are skipped with the same VIEW rule as a live run. +Enabled spawn-agent members are included when the endpoint grants that capability. +The effective endpoint must grant the tools capability. Tool discovery uses the configured +per-admission concurrency (one to ten, default three), must complete, and must contain all +explicitly selected tools; wildcard selections require a nonempty catalog. Request disconnects +and scheduler shutdown cancel connection setup and discovery without advancing the occurrence. +Readiness admissions use a separate bounded pool and complete before a durable generation +slot is reserved, so slow MCP servers cannot consume generation capacity or block later +healthy occurrences from being considered. + +Supported authentication is determined by a successful unattended connection: + +- Static server credentials and anonymous servers. +- Persisted custom user variables, including API keys. +- Stored MCP OAuth credentials that can connect or refresh without user interaction. + +Browser-only credentials, interactive OpenID bearer/OBO sources, missing user +variables, and OAuth grants needing renewed consent cannot be assumed available. +Reconnect or configure the server in an interactive agent chat, or remove it from the +agent, then enable the schedule. A browser connection alone does not prove readiness; +enabling always reruns the unattended check. + +`mcp_reauth_required`, `mcp_configuration_missing`, and `mcp_permission_denied` stop a +scheduled occurrence and disable the schedule immediately. The permission status tells +the owner that an administrator must restore MCP use access. `mcp_unavailable` counts +toward the existing configured consecutive-failure threshold. Credential-store and +configuration-store outages are transient; they must never be treated as proof of missing credentials. +Failure records contain only server names and resolution statuses, never exception +messages or OAuth URLs. Successful dispatch records also retain the server outcomes. + +The schedule card shows failed servers and links to the selected agent for recovery. +A pure pause remains available even when MCP validation fails.

Preflight is validation, not a provisioning/consent hook: +hosts must not create durable grants keyed by this proposed ID. Failed admission or a +concurrent idempotency-key winner can discard it. Edits +and dispatch use the existing schedule ID. Execution derives the context from the +verified schedule trigger and authenticated owner, then captures it before tool loading. +`agentId` identifies the root scheduled agent throughout child execution and handoffs. +After an approval pause, the resume host restores the context from the saved job after +validating ownership, tenancy, agent identity, and schedule liveness. An explicit initializer +argument carries this restored context; resume body fields cannot replace it. +The existing resolver closure is passed through tool discovery, execution, and reconnects; +it never goes into tool arguments or durable job payloads. + +Each OBO consumer supplies its server name and configured scopes after its existing trust +check. A run shares in-flight lookups and successful providers only for identical server +and scope pairs. Failed or empty lookups may retry; cancellation belongs to the owning run, +so cancelling one child does not cancel a sibling's lookup. + +`tenantId` is absent in deployments without tenancy. `context` is absent for legacy callers +that supply no schedule ID or verified trigger, and `target` is absent for legacy consumers. +Existing callbacks may ignore the new fields. Hosts needing either field must reject its +absence.
