Marco Beretta	edd614bbff	🧰 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 --------- Co-authored-by: Danny Avila <danny@librechat.ai>	2026-07-05 11:30:12 -04:00
Danny Avila	7b7fa496aa	🗃️ perf: Cache Group Memberships for ACL Principal Resolution (#14075) ... * 🗃️ perf: Cache Group Memberships for ACL Principal Resolution Continues #14069: caches resolved group-membership ids per member key in a new USER_PRINCIPALS namespace so repeated permission checks skip the group query, with exact invalidation on every membership mutation, same-process build dedup, and optional Redis cross-container build locks. Co-authored-by: Peter Rothlaender <peter.rothlaender@ginkgo.com> Co-authored-by: Joachim Keltsch <joachim.keltsch@daimlertruck.com> * 🧵 fix: Defer Transactional Invalidation and Gate No-Op Bulk Clears Codex round-2 findings on the principals cache: membership writes inside a transaction now defer cache invalidation until the session ends so concurrent readers cannot re-cache pre-commit state with no later correction, and bulkUpdateGroups skips invalidation entirely when MongoDB reports no modified or upserted documents. userGroup.spec.ts now runs on a single-node replica set so the deferral is covered by a real transaction. * 🌐 fix: Evict Cross-Process Stale Rewrites and Scope Entra Sync to Tenant Codex round-3 findings: a delayed second invalidation pass (lock wait plus a short grace) now evicts membership entries that a build in another container re-cached after the first delete, and syncUserEntraGroupMemberships establishes the user's tenant ALS context when the OAuth callback runs it pre-middleware, so tenant-scoped principal keys are invalidated (and sync queries and created groups are scoped) exactly like authenticated reads. Deferred transactional invalidations snapshot the caller's ALS so they keep tenant scoping. --------- Co-authored-by: Peter Rothlaender <peter.rothlaender@ginkgo.com> Co-authored-by: Joachim Keltsch <joachim.keltsch@daimlertruck.com>	2026-07-05 08:40:14 -04:00
Danny Avila	424ccffd83	🪝 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.	2026-07-02 11:51:24 -04:00
Danny Avila	6b049c2eed	🧠 fix: Default Bedrock thinking maxTokens to model max output (#14058) ... * 🧠 fix: Default Bedrock thinking maxTokens to model max output 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: canonicalize number-first Claude aliases before resolving max output	2026-07-01 18:29:45 -04:00
Danny Avila	8683eccbbc	🧠 fix: Apply Bedrock thinking config to bare inference-profile model IDs (#14054) ... * 🧠 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	2026-07-01 14:19:34 -04:00
Malte Polley	e88f7a8f19	📧 fix: Add .eml (message/rfc822) Support to File Upload (#13989) ... * fix: add .eml (message/rfc822) support to file upload * chore: restore package lock metadata --------- Co-authored-by: Malte Polley <ahabsfriend@posteo.de> Co-authored-by: Danny Avila <danny@librechat.ai>	2026-07-01 09:21:14 -04:00
Alexey Korepanov	ac759ef2f7	🥷 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.	2026-06-30 19:32:59 -04:00
Danny Avila	9f8b6d92c0	🤖 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'}.

Danny Avila	6dbf9d5ad3	🪝 feat: Human-in-the-Loop Runtime - Tool Approval + Ask-User-Question (Slice B) (#13942) ... * chore: add @langchain/langgraph-checkpoint-mongodb for HITL durable resume * feat: HITL tool approval runtime — backend (Slice B) - endpoints.agents.checkpointer config + durable Mongo checkpointer (seam over the app connection; SDK MemorySaver fallback) with a TTL index + deleteThread pruning - HITL run wiring (PreToolUse policy hook + humanInTheLoop) attached in createRun, fully inert when toolApproval.enabled is off - interrupt gate (pause job -> requires_action + emit on_pending_action) and a resume route that rebuilds the run from the durable checkpoint and run.resume()s it - atomic single-winner resolve; agent-consistency guard; expireStaleApprovals terminal event; checkpoint pruned on every non-paused completion (thread_id == conversationId) * feat: HITL tool approval UI — frontend (Slice B) approve/reject/edit/respond + ask-user controls in the tool card (OAuth-button precedent), batch-aware single submit, live + reconnect (resumeState.pendingAction) wiring, and resume mutations posting to /agents/chat/resume. * fix(hitl): decouple ApprovalProvider from chat context ApprovalProvider is now pure state (safe to mount in provider-less / shared / test renders); the context-dependent submit moved to a useResumeSubmit hook the cards call. Part imports getAskUserQuestionPart from ~/utils/approval directly so suites that partial-mock ~/utils render Part without throwing. * fix(hitl): address Codex review — backend - P1: enforce per-tool allowed_decisions on resume (reject a crafted decision the policy disallows) via findDisallowedDecisions - prune the durable checkpoint on user-abort of a paused run, and before a fresh HITL turn, so a new turn cannot rehydrate an expired/aborted interrupt (thread_id is the stable conversationId) - persist + use isTemporary and the original parentMessageId on resume (temporary chats stay temporary; initializeAgent scopes thread files off the right parent) - generate a deferred first-turn title BEFORE completeJob so its event reaches the client and the final event carries the real title - moderateText: skip when there is no text (tool-approval resume) and moderate the ask-user answer, instead of denying on an empty input * fix(hitl): address Codex review — frontend - render ToolApproval for ANY paused agent tool card (bash/code/file/etc.), not just the generic ToolCall, by wrapping the tool-card branch in Part (moved the rendering out of ToolCall) - findPendingActionMessageIndex only matches an assistant message, never the user message (the underscore-strip could target the user bubble before the assistant placeholder exists) * fix(hitl): address Codex re-review - title eligibility checks the user message’s parent (first turn), not the response’s parent — the previous check could never be true and skipped title generation - use client.buildResponseMetadata() for the resumed message so contextUsage / thoughtSignatures survive (the abort-only helper dropped them) - moderate decisions[].responseText (the respond action’s user text) - give /chat/abort req.config (configMiddleware) so the HITL checkpoint prune on abort actually runs - read resume state BEFORE setContentParts so the in-memory store does not lose the pre-pause seed content - count resumes against LIMIT_CONCURRENT_MESSAGES (increment/decrement) so paused-then- resumed turns cannot bypass the limit - require actionId on resume so a body without it cannot resolve the current action * fix(hitl): address Codex re-review (round 3) — resume fidelity Bring the lean resume path to parity with sendMessage for things it bypassed: - carry userMCPAuthMap into the rebuilt run so approved MCP tools keep the user's creds - seed initialSessions (buildInitialToolSessions) so approved code/file/skill tools have the pre-pause uploaded-file context (esp. cross-replica / after restart) - await client.artifactPromises and persist them as response attachments (else tool artifacts created after the pause vanish on reload / for late subscribers) - merge metadata: cumulative usage (+ summary marker) from the job, contextUsage / thoughtSignatures from the client — fixes the round-2 regression that underreported post-resume cost * fix(hitl): address Codex re-review (round 4) — resume hardening - resume: require an EXACT paused agent_id match (reject omitted/ephemeral agent_id, not just a different one) and reject an endpoint mismatch, so a request can't rebuild the claimed checkpoint on a different graph - moderateText: also moderate a tool-approval decision's reject `reason` and stringified `editedArguments`, not just `responseText` - request: re-mark the paused response `unfinished:true` after BaseClient saves it as completed, so an expired / never-resumed approval doesn't leave a "finished" response in history; the resume path overwrites it on success * test(hitl): route-level integration test for the resume controller Adds api/server/controllers/agents/__tests__/resume.spec.js, a supertest integration test that drives the real ResumeAgentController over the full pause -> approve -> resume -> finalize lifecycle with the SDK run, durable checkpointer, Mongo, and concurrency cache mocked. The pure decision/liveness helpers run for real via requireActual, so the guard ladder is exercised end to end rather than stubbed. 25 cases covering: - the authorization / staleness / agent-and-endpoint / actionId guard ladder - tool_approval validation (undecided tool call, policy-disallowed decision) - ask_user_question answer requirement - the concurrency gate (429) and the atomic single-winner claim (409) - the happy path: ACK, run reconstruction, decision->SDK mapping, finalize (save the now-finished response, emit done, complete job, prune checkpoint) - first-turn title generation before stream completion - re-pause (no double finalize), abort-during-resume (no double finalize), and the resume-failure terminal path (emitError + completeJob + prune) * test(hitl): strengthen resume coverage + add approval util tests Acts on a self-audit of the new resume integration test. resume.spec.js (25 -> 32 cases): - replace the tautological emitDone assertion (it only checked the hardcoded `final: true`) with a structural check of the finalEvent payload — responseMessage content/id/unfinished, requestMessage identity, title - cover the previously-unwalked finalize branches: tool-artifact attachments (null-filtered), the aggregatedContent fallback when live content is empty, and client response-metadata attachment - add guard cases: unsupported pending-action type (400) and the pre-multi-tenancy null-tenantId pass-through (must not 403) - add error-path cases: first-turn title generation throwing must still finalize, and a completeJob failure during a resume error must force a terminal job state via the last-resort updateJob client/src/utils/approval.spec.ts (new, 15 cases): - applyPendingAction tool_approval: join by tool_call_id not position, skip completed calls, default allowed_decisions to [], referential stability when nothing changes - applyPendingAction ask_user_question: append, idempotent replace on replay, non-array content coercion - getAskUserQuestionPart type guard; findPendingActionMessageIndex assistant-only resolution (never resolves to the user bubble) * fix(hitl): address Codex re-review (round 5) Five findings verified against the code before fixing: - resume: require an EXACT endpoint match (like agent_id) — a resume that OMITS endpoint must not fall through, since the shared chat middleware treats a missing/non-agents endpoint as the ephemeral agent and could rebuild the claimed checkpoint on a different graph - resume: filter malformed content parts before saving the finished response, matching the normal AgentClient path (a resumed turn could otherwise persist an empty/invalid tool_call part that breaks reload/rendering) - resume: accumulate tool artifacts across pause segments — persist them on re-pause and MERGE (not overwrite) at finalize, so artifacts produced before a second approval pause aren't dropped by the next rebuilt client - approval (client): findPendingActionMessageIndex returns -1 when a provided responseMessageId isn't found, so the caller retries instead of attaching the prompt/approval to a prior assistant reply; fall back to the last assistant only when no responseMessageId is given - RedisJobStore: make appendChunk extend-only (XADD + EXPIRE-if-shorter via a single eval) so the on_pending_action chunk emitted after a pause can't reset the chunk-stream TTL back to the running window and evict pre-pause content before the approval is resolved Tests: +endpoint-omitted/unsupported-type/malformed-filter/attachment-merge/ re-pause-persist cases in resume.spec.js (36); ask-retry -1 semantics in approval.spec.ts (16); extend-only TTL assertion in the RedisJobStore Redis integration spec. * test(hitl): mongodb-memory-server integration test for the checkpointer seam The checkpointer unit spec covers config/selection with no DB connection; this exercises the durable Mongo seam against a real (in-memory) MongoDB — the part correctness actually depends on: - getAgentCheckpointer builds a real MongoDBSaver when Mongo is connected and setup() creates the TTL index (expireAfterSeconds) on the checkpoint collection - memory type returns undefined (SDK MemorySaver fallback) even when connected - saver is memoized per resolved config - deleteAgentCheckpoint prunes a thread's persisted checkpoint (the cross-turn isolation guarantee: turn N+1 on the same conversationId can't rehydrate it) - pruning is thread-scoped — deleting one conversation leaves others intact - undefined threadId is a no-op * fix(hitl): address Codex re-review (round 6) Four findings verified against the code before fixing: - messageFilterPii: scan the resume payload's user-authored text (ask-user `answer`, and a tool-approval decision's `respond` text, `reject` reason, and edited tool arguments) — the shared /resume route ran through the PII filter but it only inspected req.body.text, so a blocked token rode the resume payload back into the model/tool (mirrors the earlier moderateText fix) - resume: re-prime skill files invoked in the pre-pause segment before rebuilding the run, so an approved code/file-backed tool keeps the injected skill-file session refs instead of running without them (mirrors the normal path's primeInvokedSkills; the pre-pause content stands in for the message payload) - hitl: pin the graph identity. Persist a fingerprint of the graph-determining request fields (endpoint, agent_id, model, spec, ephemeralAgent — normalized) on the pending action at pause, and reject a resume whose recomputed fingerprint differs. This closes the ephemeral-agent gap, where agent_id is undefined so the id guard can't tell two ephemeral configs apart - resume: reject incomplete edit/respond decisions (findIncompleteDecisions) — an `edit` without an object editedArguments or a `respond` without non-empty responseText is 400'd before mapping, rather than defaulting to {} / '' and resuming with behavior the user never approved Tests: incomplete-decision + fingerprint match/mismatch cases in resume.spec.js (41); findIncompleteDecisions + computeAgentRequestFingerprint unit tests; and resume-field PII cases in messageFilterPii.spec.ts. * fix(hitl): address Codex re-review (round 7) Four findings verified against the code before fixing: - RedisJobStore: clear `agent_id` on createJob (add it to staleHitlFields). The job hash is keyed by conversationId and reused across turns; updateMetadata only writes agent_id when truthy, so a conversation that switched from a saved agent to an ephemeral/no-agent turn kept the old id and the resume guard rejected the valid pause as a different agent. (real correctness bug) - fingerprint: include `promptPrefix` in computeAgentRequestFingerprint, and re-send it on resume (ResumeAgentFields + buildResumeFields). Ephemeral agents derive their system instructions from promptPrefix, so a resume changing it previously passed the pin and rebuilt different instructions. (completes the round-6 fingerprint) - resume: the re-pause branch now persists the segment's accumulated CONTENT (filtered), not just artifacts, so an approval that expires/reaps without a final resume no longer loses everything streamed during the resumed segment. - request: carry `manualSkills`/`alwaysAppliedSkills` on the persisted user message so a resumed turn's reconstructed requestMessage keeps its skill pills instead of dropping them until a full reload. Deferred (narrow, no safe contained fix yet — see PR thread replies): - resume rebuild without `addedConvo` for a multi-conversation/added-agent pane - cross-replica re-prime of manually-selected (not model-invoked) skill files Tests: stale-agent createJob clearing (Redis integration), promptPrefix fingerprint match/mismatch (resume.spec.js + policy.spec.ts), re-pause content persistence (resume.spec.js). * fix(hitl): address Codex re-review (round 8) Five findings verified against the code before fixing; the headline is a durable- resume correctness fix (the fingerprint had surfaced it as a 403): - resume durability (the important one): persist the graph-determining request fields (endpoint, agent_id, model, spec, promptPrefix, ephemeralAgent) on the pending action as `resumeContext`, and REPLAY them onto the resume request via a router-level middleware that runs before buildEndpointOption. The client can't reconstruct the ephemeral-agent config after a reload/cross-session, so the round-6/7 fingerprint would 403 a valid durable resume — and even without it the rebuilt agent would lose its tools. Replaying server-side rebuilds the SAME graph regardless of client state (and a crafted resume can't swap it; the fingerprint still matches because the body is restored first). - RedisJobStore: also clear `isTemporary` on createJob (same class as agent_id): a prior temporary turn's flag would otherwise survive a reused conversation hash and a later non-temporary resume would save its response as temporary. - resume: persist `contextMeta` (context-window calibration) onto the saved response like BaseClient does, so the next turn can seed its pruner. - request: carry manualSkills/alwaysAppliedSkills into the onStart metadata update (not just the preliminary one it overwrites), so a resumed turn's requestMessage keeps its skill pills. Deferred (narrow — see thread reply): - saved-agent edited WHILE a run is paused: agent_id matches but the definition changed; needs an agent version/config hash, which is a larger change for a narrow window. Tests: resumeContext pick/apply + round-trip (policy.spec.ts), contextMeta + manualSkills-on-requestMessage (resume.spec.js), isTemporary clearing (Redis integration). * style(hitl): prettier line-wrap in policy.spec.ts (R8 lint fix) * fix(hitl): address Codex re-review (round 9) Five findings, all fixed (addedConvo — deferred in rounds 7/8 — is now trivial thanks to the round-8 replay): - replay addedConvo: add it to RESUME_CONTEXT_KEYS so the resume middleware restores the parallel/secondary-agent config from the paused request; the client can't reconstruct it, and it determines the rebuilt graph. - skill pills (the real fix this time): the round-8 onStart metadata write was overwritten by trackUserMessage (the authoritative userMessage writer). Carry manualSkills/alwaysAppliedSkills in the emitted `created` message and persist them in trackUserMessage; widen UserMessageMeta + SerializableJobData.userMessage. - execute-code files on resume: seed the paused user message's own files onto req.body.files before initializeClient — they're excluded from the parent-walk code-session rebuild, so an approved code/read-file tool would otherwise resume without them. - in-memory pending-action UI: route ApprovalEvents.ON_PENDING_ACTION in the resume replay/pending-event loops to applyPendingActionToMessages (mirror the live handler), so a pause that lands in the snapshot window still renders its approval controls instead of sitting paused with no UI. - abort isTemporary: the /chat/abort partial-save now sources isTemporary from the job metadata, not req.body (the stop button posts only conversationId), so aborting a paused temporary chat no longer persists an orphaned partial. Tests: addedConvo in pickResumeContext (policy.spec.ts), file-restore on resume (resume.spec.js), abort-from-job-isTemporary (abort.spec.js). * fix(hitl): address Codex re-review (round 10) — resume/expiry races Three concurrency/coherence findings, verified against the code before fixing: - expiry-sweep CAS scope: both stale-approval sweeps (GenerationJobManager expireStaleApprovals and the RedisJobStore requires_action cleanup) called expire()/transitionStatus WITHOUT the observed pendingAction.actionId, so the CAS only checked status===requires_action. Between the read and the CAS a user could resolve the observed action and the run re-pause on a FRESH action; the stale sweep would then abort that valid new pause. Now both pass the observed actionId as expectActionId, so the CAS only fires for the action read as stale (a re-paused action has a different id → no-op). - resume graph cache: resumeCompletion cached the rebuilt graph (created with messages:[]) via setGraph; RedisJobStore.getContentParts prefers a cached graph over reconstructing from the chunk log, so a same-replica reload/status poll mid-resume returned aggregatedContent missing the pre-pause content. Skip setGraph on resume so introspection falls back to the complete chunk reconstruction (setContentParts still seeds the in-memory store). - pending-action UI: applyPendingActionToMessages scheduled a SINGLE animation-frame retry then dropped the pending action; Recoil/React updates can take several frames under load, leaving a valid requires_action run with no approval controls. Retry across frames (bounded at 120) until the target message commits. Test: expire() with a mismatched expectedActionId no-ops while the matching id expires (pendingAction.spec.ts). * chore(deps): update @librechat/agents to version 3.2.53 and @langchain/langgraph to version 1.4.7 in package-lock.json and related package.json files * refactor(hitl): add resolveToolApprovalPolicy seam for layered policy Extract the single point where tool-approval policy is resolved for a turn (`resolveToolApprovalPolicy`) and route the run call site through it instead of reading `endpoints.agents.toolApproval` inline. Behaviour-preserving: only the `endpoint` layer is wired today, so the result is identical to reading the app policy directly. The `agent` and `skills` layers are reserved seams with documented precedence (endpoint owns the `enabled` kill switch; agent overrides mode/allow/deny/ask/reason; skills may only tighten), so future per-agent and per-skill policy plumbing lands in one function rather than at the `createRun` site. Adds focused unit tests. * fix(hitl): address Codex re-review (round 11) — resume hardening F1 (P2, security) — applyResumeContext now DELETES any RESUME_CONTEXT_KEY absent from the persisted context, so the resume body carries exactly the graph-determining fields the pause had. Previously only defined keys were overwritten, leaving a client-supplied `addedConvo` (which the request fingerprint does not cover) in place — a crafted resume could rebuild a single-agent checkpoint as a different multi-agent graph/tool set. F3 (P2) — the resume route ACKs (res.json) before initializeClient, so a post-ACK getMCPRequestContext(req, res) saw the response as finished and returned undefined, leaving the resumed run without its run-scoped MCP connection store (approved MCP / OAuth-overlay tools then ran without their request-scoped connections). Pre-seed the store with a null res + cleanupOnResponse:false before the ACK and tear it down in the finally, mirroring the normal stream path (request.js). userMCPAuthMap was already preserved separately, so credentials were not lost — only the connection store. Declined: the ApprovalContext NEW_CONVO guard (P2) is a false positive — the `created` SSE event updates the conversation atom before any pause renders, so the id is concrete by click time (details in the PR thread). Tests: policy.spec (absent-key delete) + resume.spec (MCP context pre-seed/cleanup order). * fix(hitl): address Codex re-review (round 12) — resume fidelity + multi-tool UI F4 (P2) — temporal prompt vars: resume rebuilt the agent without restoring req.conversationCreatedAt or req.body.timezone, so {{current_datetime}}-style vars compiled a different system prompt than the paused graph (resume wall-clock, unzoned). Add 'timezone' to RESUME_CONTEXT_KEYS (persisted at pause, replayed by the resume middleware) and restore conversationCreatedAt from the convo before initializeClient — mirroring the normal path's resolveConversationCreatedAt. F5 (P2) — multi-tool approval: applyPendingActionToMessages stopped retrying once ANY tool-call part was tagged, so siblings that rendered on later frames never got approval controls and the resume route 400'd the partial batch. Add countTaggedApprovalParts and keep the bounded RAF retry going until every action_request is tagged (ask_user_question unchanged — one synthetic part). F6 (P3) — Edit accepted `null`/`[]` (valid JSON, non-object), enabling Submit for a value the resume route rejects via findIncompleteDecisions. Mirror the server's plain-object check in the client (store + editIsValid) so Submit only enables for an accepted value. Tests: policy.spec (timezone round-trip), resume.spec (conversationCreatedAt restore), approval.spec (countTaggedApprovalParts). * fix(hitl): address Codex re-review (round 13) — recurse into subagent approvals F9 (P2) — a tool paused INSIDE a subagent has its tool_call_id in the parent subagent tool_call's nested `subagent_content`, not as a top-level message part. applyToolApproval and countTaggedApprovalParts only scanned top-level content, so the approval never attached and the round-12 retry loop counted 0 tagged parts and spun to its frame cap with no controls. Both now recurse into `subagent_content` (immutably, so React refs update): the nested call gets tagged and is counted, so the retry terminates. Added approval.spec cases for the nested tag + count. Note: surfacing the interactive approve/reject controls inside the subagent view is a deliberate follow-up — ToolApproval -> useResumeSubmit -> useChatContext crashes when rendered in the portaled subagent dialog (outside the chat/approval providers), so that needs the controls scoped to the in-provider inline render (or the dialog wrapped with the providers). This commit fixes the data/traversal layer only. F7 (discovered-tool history on resume) and F8 (redis chunk TTL pause race) were verified false positives — see the PR threads. * fix(hitl): address Codex re-review (round 14) — resume fidelity + expiry relay F13 (P2) — manualSkills are graph-determining (skill allowed-tools union into the tool set before tools load) but weren't replayed, so a reload lost the skill tools and a crafted resume could inject a different skill past the fingerprint. Add 'manualSkills' to RESUME_CONTEXT_KEYS (same replay-only pattern as timezone/ addedConvo; the delete-absent half blocks injection). Not alwaysAppliedSkills — that's resolved server-side from the DB, not req.body. F12 (P2) — the resume final SSE built requestMessage from job.metadata.userMessage (persisted without files), so attachments vanished from the user bubble on resume. Spread the already-restored req.body.files onto it, matching the normal path. F11 (P2) — multi-replica approval expiry: RedisJobStore.cleanupRequiresActionIndex on another replica can win the requires_action->aborted CAS (it sets the hash error but has no event transport), and the local sweep then skips because the job is no longer requires_action, so a client subscribed here never gets the terminal error until the reap path. expireStaleApprovals now relays APPROVAL_EXPIRED_ERROR for a locally-subscribed job already aborted FOR approval expiry (error-string gated, idempotent via the errorEvent flag). emitError already publishes cross-replica. Tests: policy.spec (manualSkills round-trip + inject-drop), resume.spec (final requestMessage carries restored files). * fix(hitl): render approval controls for subagent-nested tool pauses (F10) Round-13 made applyToolApproval/countTaggedApprovalParts recurse into subagent_content (data), but SubagentDialogPart rendered nested TOOL_CALL parts with <ToolCall> only and never mounted <ToolApproval>, so a tool paused inside a subagent showed no controls and the run was unresolvable. Render <ToolApproval> in SubagentDialogPart's TOOL_CALL branch when the nested tool_call carries an approval and isn't yet resolved, mirroring the top-level Part.tsx render. The subagent dialog portals (OGDialog → ReactDOM.createPortal), but React context flows through the React tree, not the DOM tree, so ToolApproval resolves ApprovalProvider/ChatContext and the controls work + submit. Also harden useResumeSubmit: read ChatContext via useContext (non-throwing) instead of the throwing useChatContext wrapper, so the cards never crash when rendered outside a ChatContext.Provider (e.g. a search/citation render that passes chat context as a prop) — they degrade to inert (buildResumeFields returns null). * style(hitl): re-sort run.ts imports after dev rebase * fix(hitl): address Codex re-review (round 15) — resume content fidelity F14 (P2) — hide_sequential_outputs was applied in chatCompletion before saving/emitting content but not on resume, so a sequential-agent chain that pauses for HITL and resumes persisted/emitted intermediate outputs the setting is meant to hide. Extracted the filter into applyHideSequentialOutputsFilter() and call it from both chatCompletion and resumeCompletion (after handleRunInterrupt, covering the finalize + re-pause reads of client.contentParts). F16 (P2) — on a reloaded HITL pause, the DB already holds the paused user row + partial assistant row; useResumeOnLoad fed those as submission.messages, then finalHandler/createdHandler appended the same pair via requestMessage/responseMessage, duplicating the turn (buildTree doesn't dedupe children by messageId). buildSubmission- FromResumeState now strips the paused user/response rows (by messageId, incl. the padded/unpadded response id) from submission.messages — they're re-supplied by the placeholders + final event. Frontend-only; live (non-reload) pause path untouched. Deferred: F15 (collapsed-card subagent approval registration/visibility) — see thread. Tests: client.test (filter keeps last + tool_call parts / no-op when off), useResumeOnLoad.spec (paused pair stripped from submission.messages). * fix(hitl): address Codex re-review (round 16) — chunk TTL, slot, job replacement F17 (P2) — chunk-stream TTL on pause-before-chunk. CHUNK_APPEND_LUA derived its ceiling only from the chunk key's current TTL, so when the chunks key didn't exist at pause (fire-and-forget append in flight, or an ask-user pause before any chunk), the on_pending_action append created the stream with only the 20m running TTL while the approval window is 24h — content evicted before resume. The Lua now also reads the job key (KEYS[2]); when status == requires_action it takes max(running, TTL(jobKey)) (the approval window transitionStatus set), else the running TTL. Extend-only preserved; gated on paused status so normal runs never inflate. Both keys share {streamId} (cluster-safe). F19 (P2) — with LIMIT_CONCURRENT_MESSAGES, the approval prompt was emitted before the original request released its slot, so a fast Approve got /resume 429'd. handleRunInterrupt now releases the slot (idempotent via pendingRequestReleased) right after the pause, before the prompt; the request.js pause branch and resume.js finally only release if it didn't (no double-release). F20 (P2) — finalizeResumedTurn never checked the job wasn't replaced before emitDone/ completeJob/saveMessage, so a stale resume could clobber a newer turn that reused the conversationId. Added the createdAt guard the normal request path uses (skip finalization when the live job's createdAt != the paused job's). Deferred: F18 (subagent_content not reconstructed on Redis resume) — joins the subagent cluster (F15). See thread. Tests: RedisJobStore integration (pause-before-chunk gets approval TTL; running stays short), resume.spec (skip finalization on replacement; no double slot release on re-pause). * 🛡️ fix: Guard HITL terminal side-effects against job replacement Jobs are keyed by streamId == conversationId, so a new request REPLACES the running one on the same conversation. The replaced generation's tail must not clobber the live generation's state. Each path now re-reads the live job and compares createdAt against the generation's captured identity before acting. - Thread the generation's createdAt onto the client (request.js + resume.js) as client.jobCreatedAt — the identity every guard compares against. - handleRunInterrupt: skip approvals.pause when this run is no longer the live job, so a stale interrupt can't flip the NEWER job to requires_action. - chatCompletion finally: skip the checkpoint prune when replaced, so an older run's late finally can't delete the newer run's resume checkpoint. - resume catch-path: gate emitError/completeJob/prune behind a stillLive check (fail-open if the read throws), mirroring finalizeResumedTurn's success guard. - Persist the turn's uploaded files on job.metadata.userMessage (authoritative trackUserMessage writer) and prefer them on resume over the user DB row, whose save can still be racing a fast /resume. Tests: 13 guard-predicate cases in jobReplacement.spec.js. * 🔁 fix: Harden HITL resume — ownership re-check, file seeding, deferred-tool replay Three follow-ups to the round-17 job-replacement guards (Codex review 4594099963): - G1 (resume.js): the success-path ownership guard runs at the START of finalizeResumedTurn, but saveMessage + first-turn title generation await long enough for a new request to replace the job on the same conversationId. Re-read the live job immediately before emitDone/completeJob/prune so the terminal writes can't tear down the REPLACEMENT job — mirrors the catch-path guard. - G2 (request.js): onStart's metadata/chunk writes that persist the turn's files are fire-and-forget, so a fast approval could read job.metadata.userMessage before files landed. Seed files into getPreliminaryUserMessage instead — that write is AWAITED before the run starts, so files are durable before any interrupt can emit. - G3 (run.ts + client.js + resume.js + IJobStore.ts): the resumed graph is rebuilt with messages: [], so createRun's tool_search-discovery scan finds nothing. A deferred tool discovered earlier in the turn (and targeted by the paused call) was therefore absent from the rebuilt schema-only toolMap — resume would throw "unknown tool" (no loadRuntimeTools fallback is wired). Capture discovered tool names at pause via extractDiscoveredToolsFromHistory(run.getRunMessages()), persist them on job.metadata.discoveredTools, and replay them into createRun's new discoveredToolNames input (merged with message-extracted names, gated on hasAnyDeferredTools — inert otherwise). A new createRun test proves the deferred tool is promoted with the replay and absent without it (reproducing the bug). Tests: real createRun deferred-replay suite (run-summarization.test.ts) + G1/G2/G3 guard predicates (jobReplacement.spec.js). Full suite green. * 🔒 fix: Close HITL resume metadata + file-substitution + pause-race gaps Four findings on the round-18 commit (Codex review 4594430222): - H1 (P1, regression in round-18 G3): the discoveredTools captured at pause never reached resume — three metadata allowlists dropped it: GenerationJobManager .updateMetadata, RedisJobStore.deserializeJob, and buildJobFacade (plus the GenerationJobMetadata type). Added discoveredTools to all four, so the deferred-tool replay actually works end-to-end (in-memory store already kept it via Object.assign). - H2 (P2, security): /resume honored a client-supplied `files` array, letting a crafted client resume an approved code/read-file tool against a DIFFERENT file set than the one approved (files aren't in the resume fingerprint/context). Resume now ALWAYS sources files from the paused job (metadata → DB row), clearing any client-supplied set. - H3 (P2, ephemeral fidelity): non-default model parameters (temperature, max tokens, custom endpoint params) were lost on resume — ephemeral agents derive them from the request body, which the resume payload omits. Capture the resolved model_parameters in resumeContext at pause and replay them onto the body on resume (excluding `model`, which is replayed via the fingerprinted RESUME_CONTEXT_KEYS path). Saved agents already source these from the DB. - H4 (P2, Redis race): a pause landing between the resume snapshot and the Pub/Sub subscription reached neither resumeState.pendingAction nor (Redis) pendingEvents, and approval events aren't persisted to replayEvents — the client attached to a paused job with no approval UI. subscribeWithResume now re-reads the live job AFTER subscribing and surfaces the pending action if the snapshot missed it (live read, no staleness). Tests: discoveredTools metadata round-trip + subscribeWithResume re-read (pendingAction .spec.ts); client-file substitution rejection (resume.spec.js); model-parameter replay predicate (jobReplacement.spec.js). * 🧹 fix: Clear stale discovered tools, release slot on claim error, extend run-step TTL Three follow-ups on the round-19 commit (Codex review 4594783691): - I1 (P2): the round-19 discoveredTools field wasn't cleared on Redis streamId reuse. HSET only overwrites listed fields and handleRunInterrupt only writes discoveredTools when THIS turn discovers a deferred tool — so a replacement turn that pauses without its own discovery inherited the prior run's tool names and force-loaded undiscovered deferred tools on resume. Added discoveredTools to createJob's staleHitlFields HDEL list (the in-memory store already builds a fresh object, so it was Redis-only). - I2 (P2): with LIMIT_CONCURRENT_MESSAGES, approvals.resolve runs after the slot increment but before the run's try/finally, so a store/Redis error there leaked the slot until the counter TTL expired (spurious 429s on retry of the still-paused approval). Wrapped the claim in try/catch that decrements the slot and returns 500. - I3 (P3): saveRunSteps did SET ... EX running unconditionally, resetting the run-steps key to the 20-min running TTL even while the job is paused for the longer approval window — a reload after that window lost the tool timeline. Now uses a paused-window TTL script mirroring the chunk-stream no-shrink behavior (extends to the approval window when the job hash is requires_action). Also fixes a latent strict-tsc cast error in the round-19 pendingAction test. Tests: claim-throws-releases-slot (resume.spec.js); discoveredTools cleared on reuse + saveRunSteps preserves the paused TTL (RedisJobStore integration, USE_REDIS). * 🛡️ fix: Guard fast-resume save race, gate HITL to resumable routes, expire on stale submit Three findings on the round-20 commit (Codex review 4595045652): - J2 (P1): a fast /resume can claim + finalize the COMPLETED response while the original request's pause branch is still awaiting `response.databasePromise`; the later unfinished-save then overwrites the completed content. Re-check the job is still paused on THIS generation's action (a claim leaves requires_action; a replacement bumps createdAt) before marking the row unfinished; fail open on a read error. - J3 (P1): the tool-approval wiring (humanInTheLoop + PreToolUse hook + checkpointer) was applied to EVERY createRun caller when toolApproval.enabled, but the OpenAI-compatible and Responses controllers never inspect run.getInterrupt() or persist a pending action — an approval-gated tool would pause there with no approval surface or resume endpoint and the route would emit a normal final response / [DONE] with the tool call dangling. Gate the wiring on a new createRun `hitlCapable` flag, set only by AgentClient (chat + resume). - J4 (P2): a stale-action 409 on submit returned without driving expiry, leaving the job requires_action with a dead action until the periodic sweeper ran — any attached SSE client got no terminal event and the stream appeared to hang. Extracted GenerationJobManager .expireApproval(streamId, actionId) (expire CAS + terminal SSE, shared with the sweeper) and call it from the resume route when the observed action is stale. J1 (nested subagent approval controls not mounting while the details dialog is closed) is a valid frontend issue in the deferred subagent-HITL path — tracked separately (replied on the thread) since the fix touches the shared dialog primitive and needs UI verification. Tests: HITL-gate both directions (run-summarization.test.ts); expire-on-stale-submit (resume.spec.js); fast-resume unfinished-save guard predicate (jobReplacement.spec.js). * 💄 style: Wrap captureAgents signature to satisfy prettier (CI lint)	2026-06-29 16:56:41 -04:00
Danny Avila	12fea693bb	🦥 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.	2026-06-26 12:19:54 -04:00

Danny Avila	376370d610	♻️ refactor: Compute Context Gauge Client-Side, Drop Projection Endpoint (#13953) ... * ♻️ refactor: Compute Context Gauge Client-Side, Drop Projection Endpoint The /api/endpoints/context-projection endpoint re-fetched a conversation's messages from Mongo and re-tokenized them to project the context gauge for snapshot-less branches. The browser already holds those messages and their per-message tokenCounts, so this duplicated work on the request path (an unbounded read + server-side BPE tokenization until it was later capped). Move the snapshot-less estimate fully client-side, from the in-memory index: - sumBranch accumulates an uncalibrated char/4 estimate (estTokens) for count-less messages (imports / pre-feature) under the same summary cutoff - useTokenUsage folds estTokens (calibrated via the existing calibrationFamily ratio) into the existing fallback; known per-message counts render unchanged - delete the endpoint, controller, rate limiter, route, the getMessageTextStats data-schemas method, and the data-provider surface (endpoint/key/type/service/query) No DB read, no server tokenization, no rate-limit knobs; the gauge recomputes reactively from the index. Net -793 lines. * 🩹 fix: Count quotes and object-form content in client context estimate Address Codex review on the client-side context estimate: - messageChars now reads object-form content text (part.text.value), not only string text/think, so imported / pre-feature messages whose body lives in content parts are no longer estimated as zero. - Count-less user messages include their merged quote excerpts in the estimate, mirroring what the send path prepends into the prompt. * 🩹 fix: Cap over-window estimate and surface estimated tokens in breakdown Address remaining Codex review on the client-side context estimate: - Clamp the snapshot-less estimate's displayed usedTokens to maxTokens. The send path prunes an over-window branch before calling the model, so the gauge never actually exceeds the window; this avoids impossible values (e.g. 50k / 8k) without re-introducing client-side pruning. - Surface the calibrated count-less estimate as its own "Estimated" row in the breakdown popover, so a branch of only count-less imported / pre-feature messages is no longer shown as Input 0 / Output 0 under a non-zero header. * 🩹 fix: Refine client context estimate per Codex re-review - Drop calibration from the snapshot-less estimate. The removed projection never actually calibrated (the client never sent a ratio), and a ratio inflated by provider-injected context over-estimates visible imported text. - Exclude reasoning (think) / error parts from the estimate; the send path strips them, so they are not part of the next call's context. - Fold quote text into the estimate even when a tokenCount is present, since the edit route recounts tokenCount from text only and drops the merged quote. * 🩹 fix: Recount quoted user turns instead of topping up the stored count The previous round added quote chars on top of a quoted message's stored tokenCount, which double-counts the common (unedited) case where the count already includes the merged quote prompt. Match the removed projection instead: for quoted user turns, ignore the stored count and estimate the full merged text. This both avoids the double-count and still corrects the stale text-only count an edit leaves behind. * 🩹 fix: Trust stored counts for quoted turns; count tool-call parts - Quoted user turns: revert to trusting a present tokenCount. The send path's stored count already includes the merged quote (and any calibration), and the client's char/4 path is coarser, so recounting regressed normal turns. Only count-less messages estimate quotes from text. - Count tool-call name/args/output for count-less assistant messages; the formatter sends them back as context, so omitting them under-reported imported branches with tool history. * 🩹 fix: Exclude in-flight tail from estimate to avoid resume double-count On resume the live path seeds liveTokens from the partial response and also writes that content into the messages cache, where the count-less response is estimated into estTokens too — double-counting the in-flight output on the snapshot-less estimate path. sumBranch now exposes the tail message's own estimate (tailEstTokens); the estimate path drops it while a stream is live, so the in-flight response is counted once (via liveTokens). The breakdown's Estimated row uses the same in-flight-adjusted value. * 🩹 fix: Recount quoted user turns in context estimate (match send path) A quoted user turn's stored tokenCount is unreliable for the gauge: a text-only Save edit recomputes it from text alone, and the send path (needsCanonicalTokenCount in agents/client.js) recounts the quote-merged prompt every turn regardless of the stored value. Mirror that on the client — estimate quoted turns from the merged text+quotes and ignore the stored count — so snapshot-less branches don't under-report by the quote block. Reverts the earlier "trust the count" assumption, which the server disproves. * 🧹 chore: Route useResumableSSE diagnostics through the frontend logger Convert the [ResumableSSE]/[Debug] console.log and console.error diagnostics to the gated frontend `logger` (client/src/utils/logger), splitting the tag from the message so object arguments are passed through as real args (logged expandably, not stringified) and the logs stay tag-filterable and off the production console unless explicitly enabled. All log statements preserved; nothing removed. * 🩹 fix: Prefer content over text when estimating count-less messages A stopped agent response is saved with both a `text` field and a structured `content` array, and the send path formats from content. messageChars early-returned on `text`, dropping the content array (and the tool-call tokens it carries) from the snapshot-less estimate — also making the tool_call handling dead for such messages. Prefer content when present, fall back to text.	2026-06-25 15:29:31 -04:00
Danny Avila	397ddc5366	🧠 feat: Add Memory as an Agent Capability with Inline Tools and Ephemeral Badge (#13869) ... * 🧠 feat: Memory Agent Capability with Inline Tools and Ephemeral Badge Add `AgentCapabilities.memory`, which expands into the inline set_memory/delete_memory tool pair (mirroring the execute_code expansion via registerMemoryTools) when a run-level memoryAvailable gate holds: capability enabled, memory configured, MEMORIES.USE permission, and personalization not opted out. Surfaces the memory artifact as an attachment in the agents tool-end callback. Adds the ephemeral path (TEphemeralAgent.memory, load/added agent tool injection), a fully-gated memory badge plus tools-dropdown entry, the agent-builder Memory toggle with form round-trip, and a mock e2e test asserting the badge reaches the request payload. Additive to and independent of the existing post-turn memory extraction agent. * 🩹 fix: Address Codex review on memory capability (gating, validKeys, usage guard) - Strip the memory capability from the served agents capabilities when memory is not configured/enabled, so the badge, tools dropdown, agent-builder toggle, and backend capability gate stay consistent instead of exposing an inert toggle on default installs (where MEMORIES.USE defaults true). - Surface configured memory.validKeys in the inline tool definitions so the model is told the allowed keys up front, matching the runtime createMemoryTool schema. - Append a strict explicit-request usage guard to the agent instructions when inline memory tools are registered, preserving the memory-agent's privacy behavior. - Add AppService tests covering memory-capability stripping. * ✅ test: Update AppService capability snapshots for memory strip AppService now strips the memory capability from the served agents defaults when no memory block is configured; update the spec's expected capability lists to defaultAgentCapabilitiesWithoutMemory for the no-memory-config cases. * 🛡️ fix: Address Codex re-review on memory capability (round 2) - Strip the memory capability from the FINAL served agents config, not just defaults; loadEndpoints reparses any endpoints.agents block, so memory was still exposed in that common shape (packages/data-schemas/src/app/service.ts) + regression test. - Re-check the full memory gate (config, opt-out, MEMORIES.USE) inside handleTools before constructing set_memory/delete_memory, so an unsolicited tool call from a model/custom endpoint can't bypass the runtime gates (api/app/clients/tools/util/handleTools.js). - Restore the persisted memory toggle for model-spec conversations via applyModelSpecEphemeralAgent (client/src/utils/endpoints.ts). - Clear LAST_MEMORY_TOGGLE_ on logout and clear-all-chats so a stale memory preference can't leak across users on a shared browser (client/src/utils/localStorage.ts). * 🧠 fix: Address Codex re-review on memory capability (round 3) - Serialize set_memory writes and advance a running token total inside createMemoryTool, so parallel batched calls in one event-driven turn can't each pass the limit check against a stale total and collectively exceed memory.tokenLimit (packages/api/src/agents/memory.ts) + tests. - Inject the keyed memory context (withKeys) instead of withoutKeys when the running agent has the inline memory capability, so delete_memory has a visible key to target (api/server/controllers/agents/client.js). * 🔐 fix: Address Codex re-review on memory capability (round 4) - Detect inline memory by tool NAME (set_memory/delete_memory) across an initialized agent's tools + toolDefinitions, since the 'memory' marker is expanded at init and the prior string check never matched; inject the keyed memory context for any primary OR sub-agent that carries the inline memory tools (api/server/controllers/agents/client.js). - Enforce memory WRITE permissions in the inline tool gate: set_memory requires CREATE+UPDATE and delete_memory requires UPDATE (matching the REST memory routes), so a USE-only role can't mutate/delete memories via agent tool calls (api/app/clients/tools/util/handleTools.js). * 🔒 fix: Address Codex re-review on memory capability (round 5) - Gate inline memory registration (memoryAvailable) on the memory WRITE permissions (USE+CREATE+UPDATE), so a read-only-memory role no longer has set_memory/delete_memory shown to the model only for the runtime loader to refuse them (api/server/services/Endpoints/agents/initialize.js). - Enforce the per-agent memory opt-in at execution: handleTools now refuses to construct set_memory/delete_memory unless the agent actually declared them (toolDefinitions/tools), blocking hallucinated/undeclared memory tool calls from mutating memory. - Fail closed when getFormattedMemories errors with a configured tokenLimit, instead of writing as if storage were empty and bypassing the cap (api/app/clients/tools/util/handleTools.js). * 🩹 fix: Address Codex re-review on memory capability (round 6) - Fix a P1 regression from the prior round: the execution-context agent keeps the raw 'memory' capability marker (not the expanded set_memory/delete_memory names), so the opt-in check now matches the marker. This restores memory writes/deletes AND avoids hijacking an MCP tool that merely shares the set_memory/delete_memory name (api/app/clients/tools/util/handleTools.js). - Count repeated set_memory writes to the same key as replacements, not additions, against tokenLimit — set_memory upserts, so a same-key rewrite swaps its prior token contribution instead of double-counting (packages/api/src/agents/memory.ts) + test. - Gate the memory badge, tools dropdown, and agent-builder toggle on the full memory write permissions (USE+CREATE+UPDATE) via a shared useHasMemoryAccess hook, so a read-only-memory role no longer sees an enabled Memory control the backend would refuse to wire up. * 🧷 fix: Address Codex re-review on memory capability (round 7) - Recognize inline memory across both execution-context agent shapes: initializeAgent now sets a LibreChat-only memoryToolsRegistered flag on the InitializedAgent, and the opt-in/detection checks accept that flag OR the raw 'memory' marker. Fixes memory failing for processAddedConvo agents (which store the initialized config, marker already expanded) while staying MCP-name-collision-safe (api/app/clients/tools/util/handleTools.js, packages/api/src/agents/initialize.ts, api/server/controllers/agents/client.js). - Scope keyed memory context to memory-enabled agents only: useMemory now returns both keyed and unkeyed contexts, and buildMessages injects the keyed one (memory keys + token metadata) only to agents that can call delete_memory, while the primary/post-turn path keeps the unkeyed values — so a primary without memory tools no longer sees memory keys it doesn't need. * 🔏 fix: Address Codex re-review on memory capability (round 8) - Enforce memory size limits on inline writes: createMemoryTool now rejects keys over 1000 chars and values over memory.charLimit, matching the REST memory routes, so an inline-memory agent can't persist blobs the memory UI/API would reject (packages/api/src/agents/memory.ts, api/app/clients/tools/util/handleTools.js) + test. - Recheck the agents 'memory' endpoint capability at execution time, so a stale/hallucinated set_memory/delete_memory call can't mutate memory after an admin removes the capability while the agent document still carries the marker (api/app/clients/tools/util/handleTools.js). * ♻️ refactor: Move inline-memory backend logic into packages/api + share memory load Workspace boundary: the inline-memory gating/detection logic that had crept into /api now lives in packages/api/src/agents/memory.ts (TS), with /api kept as thin wrappers. - Add agentHasInlineMemoryTools, isMemoryToolAllowed, and buildInlineMemoryTool to packages/api; handleTools.js now calls buildInlineMemoryTool instead of constructing/gating the tools inline, and client.js imports agentHasInlineMemoryTools instead of redefining it. - Optimize repeated memory loads: getRequestMemories memoizes getFormattedMemories per request (WeakMap keyed by req), so the run's memory-context load and every memory-enabled agent's set_memory token-usage load share a single DB fetch instead of one per agent. * 🧠 fix: Invalidate request memory cache after inline writes Inline set_memory/delete_memory now invalidate the request-scoped getFormattedMemories cache on a successful write, so a later tool round in the same response is seeded with the post-write usage total instead of the stale pre-write one (multi-round writes no longer collectively exceed tokenLimit, and a set after a delete is not over-counted). The within-round sharing across multiple memory-enabled agents is preserved. * 🧠 fix: Persist memory capability on saved agents; honor registration flag - Add Tools.memory to the v1 systemTools allowlist so filterAuthorizedTools no longer silently drops the memory marker when an agent with the Memory capability is created/updated/duplicated through the builder (previously the capability only worked for ephemeral chats, not persisted agents). - agentHasInlineMemoryTools now honors an explicit memoryToolsRegistered boolean before falling back to the raw `memory` marker, so an initialized config whose registration was denied (memoryAvailable false) is not given keyed memory context just because the marker survives in tools. * 🧩 fix: Bring memory tool to parity with other ephemeral tools - Add `memory` to the model-spec schema/type and honor `modelSpec.memory` in both ephemeral paths (load.ts, added.ts) and the frontend spec application, so admins can pre-enable Memory from a model spec exactly like webSearch/fileSearch/executeCode. - Add LAST_MEMORY_TOGGLE_ to the timestamped-storage cleanup list so stale per-conversation memory toggles are purged on startup like the others. - Hide the agent-builder Memory toggle for users who disabled memory in personalization (memories === false), mirroring the chat badge's opt-out gate, so the setting isn't shown as inert/misleading. * ✅ test: Cover memory in applyModelSpecEphemeralAgent spec defaults Update the exact-object assertions to include the new `memory` field and add positive coverage that `modelSpec.memory` maps to the ephemeral agent's `memory` flag. Fixes the shard 2/4 failure from 672a03b05.	2026-06-24 17:14:13 -04:00
Danny Avila	771b93bf10	🪝 feat: HITL Tool Approval Scaffolding (Slice A) (#12938) ... * 🪝 feat: HITL Tool Approval Scaffolding Adds the foundational types, job-state, config schema, and policy module for human-in-the-loop tool approval. Purely additive — no behavior change on existing runs. Lands ahead of the agents-SDK interrupt/checkpointer integration so both tracks can land independently. - LangChain HumanInterrupt-shaped types in `Agents.*` namespace (`HumanInterruptPayload`, `ToolApprovalRequest`, `ToolReviewConfig`, `PendingAction`, `ToolApprovalResolution`); `ToolCall`/`ToolCallDelta` gain an optional `approval` field. - New `requires_action` job status (non-terminal) plus `pendingAction` field on `SerializableJobData` and `GenerationJobMetadata`. Both stores treat the status as paused-but-alive; Redis `updateJob` has explicit `requires_action`/`running` transition branches that refresh the hash TTL, manage the `runningJobs` set, and `HDEL pendingAction` on resume. Both stores include `requires_action` in `getActiveJobIdsByUser`. - `GenerationJobManager` gains `markRequiresAction`, `getPendingAction`, `clearPendingAction`; `getJobCountByStatus` aggregates the new status. - `endpoints.agents.toolApproval` config (`default`/`required`/`excluded`) and a policy module exporting `decideToolApproval`, `requiresApproval`, and `buildPendingAction` (the LangChain-shaped payload builder). - 20 unit tests covering policy resolution and the manager lifecycle. * 🧭 refactor: Align HITL Surface with Agents SDK Permissions Model Reshapes Slice A on top of the agents SDK's now-landed HITL surface (`createToolPolicyHook`, discriminated `HumanInterruptPayload`, `'bypass'` mode naming). Host stops reimplementing evaluation logic and becomes a config mapper + payload wrapper. Schema (data-provider): - `toolApproval` shape now mirrors SDK `ToolPolicyConfig` 1:1: `mode: 'default' | 'dontAsk' | 'bypass'`, plus `allow` / `deny` / `ask` glob lists and an optional `reason` template. `enabled` is the LibreChat-only admin kill switch. - `'bypass'` (not `'bypassPermissions'`) — matches the SDK's surface. Types (`Agents.*` namespace): - `HumanInterruptType` extended to `'tool_approval' | 'ask_user_question'`. - `HumanInterruptPayload` is now a discriminated union — `tool_approval` carries `action_requests` + `review_configs`; `ask_user_question` carries a free-form question with optional curated options. - New: `AskUserQuestionRequest`, `AskUserQuestionOption`, `AskUserQuestionResolution`. - `ToolApprovalDecision` (string union) renamed to `ToolApprovalDecisionType` to free the `Decision` name for the SDK's discriminated object union later. - `ToolApprovalResolution` gains `reason?` and `scope?: 'once' | 'session' | 'always'` so route signatures stabilize before persistence lands. Policy module (`packages/api/src/agents/hitl/policy.ts`): - Drop `decideToolApproval` / `requiresApproval` / `ToolRef` — the SDK's `createToolPolicyHook` handles full evaluation (`deny → bypass → allow → ask → dontAsk → fallthrough(ask)`). - Add `isHITLEnabled(policy)` — the kill-switch predicate that gates the SDK's `humanInTheLoop: { enabled: false }` opt-out in Slice B. - Add `mapToolApprovalPolicy(policy)` — strips `enabled`, returns a `ToolPolicyConfig` to feed `createToolPolicyHook`. Structural mirror of the SDK type so this compiles before the SDK upgrade ships. - Reshape `buildPendingAction(payload, ctx)` to wrap any `HumanInterruptPayload` with job context — accepts SDK output directly. - Add `buildToolApprovalPayload(...)` and `buildAskUserQuestionPayload(...)` helpers for synthesizing payloads in tests / pre-SDK flows. Tests: - 22 new unit tests covering the mapper, predicate, and payload builders; 20 → 27 total pass across policy + manager-lifecycle suites. * 🪢 chore: Import ToolPolicyConfig From `@librechat/agents` The SDK type now ships in 3.1.77 (already pinned on `dev`), so the structural mirror in `policy.ts` is redundant. Drop the local interface and import directly so future SDK changes to `ToolPolicyConfig` propagate without our `mapToolApprovalPolicy` going stale. * 🔑 fix: Carry tool_call_id On ToolReviewConfig (HITL) `ToolReviewConfig` was joining with `ToolApprovalRequest` by position only. That breaks the moment a single batch contains the same tool called twice (e.g. a model fanning out parallel `mcp:server:search` calls): the UI can't tell which review config applies to which action request once it filters or reorders. Mirrors the SDK's `ToolApprovalReviewConfig` shape — `tool_call_id` is the join key, `action_name` is retained for display only. Also: drop a JSDoc warning on `isHITLEnabled` so a future contributor doesn't wire `humanInTheLoop: { enabled: true }` without supplying a host checkpointer — the SDK's `MemorySaver` fallback is process-local and silently breaks resume across worker hops. - `Agents.ToolReviewConfig` adds `tool_call_id: string` - `buildToolApprovalPayload` populates `tool_call_id` per review config - New test covers the duplicate-tool batch case (two parallel calls to the same tool); 27 → 28 tests * fix: Address HITL review findings * fix: Refresh paused HITL Redis state * test: Stabilize HITL abort fallback specs * 🎨 style: Sort imports to satisfy dev lint gate (HITL) * 🏛️ refactor: Deepen HITL approval lifecycle into one race-safe seam Architecture-review candidate #1 (+ #4). The requires_action lifecycle was three shallow pass-throughs over updateJob with the legal transitions smeared across JSDoc, the JobStatus union, and each store adapter — and the resume transition was NOT race-safe: the Redis lua checked existence, not status, so two concurrent approval submits both drove the run (re-executing tools / double-billing). - IJobStore.transitionStatus: atomic compare-and-set status transition that only fires if the job is currently `from`. InMemory: sync compare. Redis: single-node lua with a status guard (cluster best-effort, matching the existing posture); reconciles membership sets + TTLs to `to`. - New ApprovalLifecycle module: pause / peek / resolve / expire — guarded, race-safe transitions behind one interface. resolve() returns true to exactly one concurrent caller; the previously-undefined requires_action → aborted expiry edge is now explicit; peek treats past-expiresAt as gone (lazy expiry). - GenerationJobManager exposes `approvals` and delegates; the three shallow methods (mark/get/clearPendingAction) are removed — callers cross the deep interface. - #4: typeContract.spec asserts the SDK <-> data-provider HITL types stay compatible (fails the build on drift); RedisJobStore validates the pendingAction shape on deserialize instead of a bare JSON.parse (defends the cold-resume path against malformed/stale records). - Tests rewritten at the deep interface: double-resolve wins once, pause-on-terminal rejected, explicit expiry, lazy-expiry peek. No Slice B wiring — this deepens the existing scaffolding so the future resume route and run seam are born crossing one race-safe interface. * 🛡️ fix: Address Codex review on the HITL approval lifecycle Seven findings on the lifecycle deepening (089ba09f9), all valid: - F3 actionId guard: resolve/expire take an expectedActionId; pause records a flat `pendingActionId` the atomic CAS guards on, so a stale decision can't resume a job that has since paused for a different action. - F4 cluster single-winner: transitionStatus now decides the winner with an atomic CAS on the single-slot job hash (one Lua, cluster-safe), then reconciles cross-slot membership sets — two concurrent resolves can no longer both win on Redis Cluster. - F1 resume reaping: resolve refreshes `lastActiveAt`; both stores' stale- running failsafes key off it, so a long-paused approval isn't reaped right after resuming. - F2 expire completedAt: expire writes completedAt so terminal cleanup reclaims the job (InMemory only cleans terminal jobs with completedAt set). - F5 facade: buildJobFacade copies pendingAction into metadata so status/ resume routes can render the prompt. - F6 resume metadata: PendingAction + buildPendingAction carry the SDK interruptId/threadId needed to rebuild Command({ resume }) cross-process. - F7 mirror: data-provider AskUserQuestionRequest gains optional description. Tests added at the interface: stale-actionId resolve rejected, expire sets completedAt. tsc + lint clean; policy + type-contract specs pass. * 🛡️ fix: Address Codex round 2 on the HITL Redis adapter Five P2 findings on abf4b86291, all valid Redis-adapter consequences of round 1: - G1 terminal cleanup on expiry: transitionStatus's terminal path now runs the same chunk/run-step/userJobs cleanup as updateJob (extracted into a shared applyTerminalContentCleanup). Expired approvals no longer leave Redis stream contents around for the full running TTL. - G2 pause via updateJob mirrors pendingActionId, so a pause through the generic path carries the flat field the stale-decision guard compares. - G3 resume via updateJob refreshes lastActiveAt (and clears pendingActionId), matching transitionStatus so a long-paused job isn't reaped post-resume. - G4 getActiveJobIdsByUser excludes a requires_action job whose pendingAction is past expiry (both stores), via shared isPendingActionExpired — the client stops polling an expired prompt. - G5 createJob clears stale pendingAction/pendingActionId/lastActiveAt on a reused streamId, so a fresh run never exposes a prior run's approval metadata and cleanup keys off the new createdAt. Tests added: expired pending-approval excluded from the active set. tsc + lint clean; policy + type-contract specs pass. * 🛡️ fix: Address Codex round 3 — approval expiry lifecycle completeness Three P2 findings on 780833d908, all valid: - H1 status consistency: /chat/status now treats a non-expired requires_action job as active (matching /chat/active), so a client refreshing while an approval is pending resumes/subscribes instead of treating the run as finished and stranding it. - H2 active expiry: cleanup now finalizes past-expiry requires_action jobs (→ aborted) in both stores instead of only filtering them from the active list — an expired prompt no longer lingers resident until key TTL. Redis routes through transitionStatus (terminal content cleanup); in-memory marks terminal + reclaims. - H3 resumed liveness: in-memory stale-running check uses max(lastActivity, lastActiveAt, createdAt), so a just-resumed job isn't reaped on a stale per-chunk lastActivity entry before the next chunk. Test added: in-memory cleanup finalizes + reclaims a past-expiry approval. tsc + lint clean; policy + type-contract specs pass. * 🛡️ fix: Address Codex round 4 — paused-job edge cases across the stack Five P2 findings on 4324a4e776, all valid: - I1 message validation: validateMessageReq's active-job read bypass now accepts a live requires_action job, so a new-conversation run that pauses before its final save can recover the prompt instead of 404ing. - I2 expire targets the observed record: resolve()'s expired path passes `expectedActionId ?? job.pendingAction.actionId`, so a concurrent resume+re-pause can't let expire abort a different action. - I3 stale/malformed prompts: new isPendingActionStale (missing OR expired) drives active-listing exclusion + cleanup expiry in both stores, and the status route + middleware require a live pendingAction — a requires_action job whose pendingAction was dropped on deserialize no longer reads active. - I4 in-memory parity: InMemory updateJob mirrors pendingActionId on pause and clears it + refreshes lastActiveAt on resume (matching RedisJobStore), so a pause via the generic path is still resolvable by actionId. - I5 long approval windows: paused-job live TTL (job/chunks/run-steps) now covers pendingAction.expiresAt + grace (pauseTtlSeconds), on both the transitionStatus and updateJob pause paths, so Redis can't evict a paused job before its decision window closes. tsc + lint clean; policy + type-contract specs pass. * 🛡️ fix: Codex round 5 — refuse unresolvable resolves; expose pending action Two of three findings on c8abd826e1 (the third deferred to Slice B): - J3 resolve() refuses a requires_action job that has lost its pendingAction (e.g. a malformed record dropped on deserialize): it expires/finalizes the job instead of driving a resumed run with no reviewed interrupt payload — consistent with how active-listing + cleanup already treat a stale prompt. - J2 /chat/status returns the live pendingAction for a paused stream, so a client rebuilding from status (reload / cross-replica) has the action id + payload to render and submit the prompt, not just "paused". Deferred (Slice B): J1 — emitting a terminal SSE event on approval expiry so already-subscribed clients close. The store-level lifecycle can't emit transport events, and there are no live SSE subscribers to a paused stream until the Slice B runtime wiring exists; tracked for that work. tsc + lint clean; policy + type-contract specs pass. * 🛡️ fix: Codex final round — paused-job TTL + pendingAction in resume contract Two of three findings on e7d9cf21b6 (third deferred to Slice B): - K2 paused-job TTL: a paused (requires_action) job no longer inherits the 20-minute running TTL — it uses a dedicated requires_action backstop (default 24h, configurable) so a no-expiry approval (the buildPendingAction default), which the API treats as live, isn't evicted by Redis mid-window. A longer pendingAction.expiresAt still extends beyond the backstop. - K3 resume contract: pendingAction is now carried on the typed ResumeState (data-provider) and populated by getResumeState for a live paused job, so a reloading / cross-replica client can rebuild the prompt from resumeState (the contract useResumeOnLoad actually reads), not just a loose status field. Deferred (Slice B): K1 — emit a terminal SSE event on expiry so already- subscribed clients close. Requires the manager/eventTransport layer (the store-level lifecycle and cleanup loops have no transport access) and has no live subscriber until the Slice B subscribe/resume path exists; tracked there. tsc + lint clean; policy + type-contract specs pass. * ♻️ refactor: dedup HITL transition path + liveness predicate (arch review) Two follow-ups from the post-hardening architecture re-review — both pure dedup, no behavior change: A — collapse the dual status-transition path. transitionStatus is now the sole membership-aware transition (running ⇄ requires_action). Removed the updateJob requires_action/running branches and the now-orphaned transitionToRequiresAction / transitionToRunning / refreshLiveJobTtls, plus the per-store pause/resume mirror logic that had to be re-synced into parity across review rounds (G2/G3/I4/I5). updateJob is back to a plain field writer + terminal cleanup. The Redis integration tests that drove updateJob({status}) now drive transitionStatus (the real path). B — one canonical "is this approval live?" predicate. isPendingActionStale / isPendingActionExpired are exported from @librechat/api and used by the stores, ApprovalLifecycle (dropped its private isExpired), the /chat/status route, and validateMessageReq — replacing 3 inlined re-derivations that were the drift source behind several review findings. tsc + lint clean; policy + type-contract specs pass. Redis integration specs (migrated) are CI-verified.	2026-06-24 16:47:16 -04:00
Marco Beretta	61016e328a	🔄 feat: Continue Shared Conversations as Personal Copies (#13714) ... Adds a "Continue this chat" button to the shared conversation view that forks the shared conversation into a new conversation owned by the viewer and opens it to continue (issue #13001). - POST /api/share/:shareId/fork, gated by requireJwtAuth, the fork rate limiters, and the canAccessSharedLink ACL (view access = fork access). - forkSharedConversation clones from the anonymized getSharedMessages payload, so only share-visible data is copied. - Strips file ids from cloned files/attachments so a fork grants no more file access than viewing the read-only share, and honors the global shared-file kill switch via the snapshotFiles option. - Reduces the clone to the viewer's active branch, located by its index in the shared payload (shared ids are re-anonymized per request and createdAt can collide, while the payload order is stable). - Resolves config/retention, persists, and reads back under the requesting user's tenant, not the share owner's; canAccessSharedLink also falls back to a system-wide share lookup so cross-tenant public shares resolve (ACL still enforced under the share's own tenant). - Resolves a usable endpoint/model from the viewer's models config instead of hard-coding OpenAI, so deployments without OpenAI can send the first message. - Routes the fork's 401s (logged-out or cold-loaded viewers) through login, including when the refresh itself is rejected for a stale session. - Hides the Temporary Chat toggle once a conversation has a real id, and portals the share-settings theme/language dropdowns above the dialog. Rebased onto dev; collapses the share-fork feature and its review fixes into a single commit.	2026-06-24 16:27:01 -04:00

Exit the migration script with a non-zero status when any per-user update fails so partial failures are not reported as successful. * style: fix import ordering in data-provider mutations * refactor: record terms acceptance atomically to preserve first-accept time Replace the read-then-write in acceptTermsController with a single atomic acceptTerms method that conditionally stamps termsAcceptedAt via an $ifNull aggregation update. This removes the TOCTOU window where two concurrent first-time accepts could overwrite the earlier acceptance timestamp, while still preserving an existing timestamp and backfilling legacy accepted users. * fix: run terms timestamp migration under system tenant context Wrap the count, cursor scan, and per-user updates in runAsSystem so the tenant isolation plugin does not throw under TENANT_ISOLATION_STRICT or scope the cross-tenant migration to a non-existent tenant, matching the other maintenance migrations. * fix: guard terms backfill against concurrent acceptances Add the missing-timestamp predicate to the per-user updateOne filter so a user who accepts through the API between the cursor read and the write keeps their real acceptance time instead of being overwritten with createdAt. Track modified vs skipped so the summary reflects skips. * fix: scope terms backfill to still-accepted users Add termsAccepted: true to the per-user updateOne filter so a reset that clears acceptance between the cursor read and the write is not re-stamped with createdAt, which would otherwise poison the next acceptance cycle through the $ifNull preserve in acceptTerms. --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>	2026-06-24 16:26:42 -04:00

Danny Avila	1662adc581	📺 feat: Google URL Context Param with Native YouTube Video Understanding (#13924) ... * ✨ feat: Add Google url_context Param with Native YouTube Video Understanding Mirror the web_search grounding wiring for a new Google/Gemini `url_context` model param (resolves to the native `urlContext` tool). When enabled, YouTube URLs in the latest user message are injected as Gemini video parts (fileData), since the URL Context tool does not support YouTube. * 🎞️ fix: Provider-aware YouTube injection limits for url_context Address Codex review on the YouTube video-understanding path: - Cap injected YouTube parts per request by provider/model (Vertex: 1; Gemini Developer API: 10 on 2.5+, 1 on earlier models) so multi-link messages cannot exceed the provider limit and get rejected. - Set a video/mp4 mimeType on Vertex YouTube fileData (matching Vertex samples); the Developer API still omits it. * 🧩 fix: Round-trip url_context for Google-compatible custom endpoints Add url_context to openAIBaseSchema so the per-chat value persists for custom endpoints configured with customParams.defaultParamsEndpoint: 'google', matching how web_search is already picked there. * 🚦 fix: Gate url_context tool to Gemini 2.5+ models Per Google's URL Context supported-models list (2.5+/3.x only), skip the native urlContext tool on earlier models (debug-log + no-op) instead of sending it and triggering a provider 400. This also gates the coupled YouTube video-understanding injection to 2.5+, since it keys off the resolved urlContext tool. * ✂️ fix: Strip YouTube URLs from urlContext text; keep url_context out of OpenAI schema - Remove url_context from the shared openAIBaseSchema (revert): it is Google-only and would otherwise leak as an unsupported param to OpenAI/Azure/OpenRouter requests. On Google-compatible custom endpoints url_context is enabled via admin addParams/defaultParams, same as web_search. - When injecting YouTube video parts, strip the matched YouTube URLs from the prompt text so the urlContext tool (which reads URLs from text and cannot fetch YouTube) does not consume its URL budget on them. Non-YouTube URLs are left intact. * 🎯 fix: Refine url_context model gating and YouTube injection edges Address Codex round 4: - Exclude non-text modality variants (image/live/tts) from URL Context support, mirroring the Google tool-combination modality exclusion. - Use the resolved run model (model_parameters.model) for YouTube injection limits instead of the saved base model. - Strip only the YouTube links actually routed to video (id-aware); keep over-limit links in the text so the model can still reason about them. - Keep timestamped YouTube links (?t=/&start=) in the text so the moment cue survives. - Recognize youtube-nocookie.com/embed links. * 🎚️ fix: Exclude audio Gemini variants + preserve pre-id YouTube timestamps Address Codex round 5: - Add `audio` to the url_context modality exclusion so audio-only Gemini variants (e.g. gemini-2.5-flash-preview-native-audio-dialog) skip the tool instead of 400ing. - Detect YouTube timestamps anywhere in the matched URL (incl. before `v=`, e.g. watch?t=90&v=<id>), so timestamped links are kept in the prompt text as intended.	2026-06-23 22:42:06 -04:00
Danny Avila	d9a76fca90	🧠 feat: Configurable Reasoning Replay for Custom Endpoints (#13921) ... * 🧠 feat: Configurable Reasoning Replay for Custom Endpoints Adds customParams.includeReasoningContent so OpenAI-compatible custom endpoints (e.g. Xiaomi MiMo, Kimi) can replay reasoning_content on tool-call turns natively, without impersonating the moonshot provider. * 🔁 feat: Replay reasoning_content across turns for opted-in custom endpoints Extends the DeepSeek reasoning-content format spoof to honor customParams.includeReasoningContent, so custom OpenAI-compatible endpoints (Xiaomi MiMo, Kimi) reconstruct reasoning_content from persisted history on later turns, matching DeepSeek thinking-mode parity. Adds shouldReplayReasoningContent predicate (tested) and surfaces the flag on the initialized agent. * 🪢 refactor: Split within-run vs cross-turn reasoning replay flags moonshot only replays reasoning_content within a run's tool calls, not across turns. Decouples the two: includeReasoningContent = within-run replay (exact moonshot parity), new includeReasoningHistory = cross-turn reconstruction from persisted history (implies includeReasoningContent, since reconstruction is a no-op without the within-run replay flag). * 🩹 fix: Apply reasoning replay across all param-format branches Move the within-run includeReasoningContent application out of the OpenAI-only branch in getOpenAIConfig to after the branch dispatch, so custom endpoints using anthropic/google defaultParamsEndpoint gateway modes also honor includeReasoningContent/includeReasoningHistory. Addresses Codex finding. * chore: Update @librechat/agents to v3.2.46 * 🧽 refactor: De-spoof reasoning replay via explicit preserveReasoningContent Now that @librechat/agents 3.2.46 exposes an explicit preserveReasoningContent option on formatAgentMessages, pass it directly instead of impersonating provider: deepseek. Behavior is unchanged (shouldReplayReasoningContent still gates DeepSeek + the custom includeReasoningHistory flag); also corrects the comment to reference includeReasoningHistory. * 🌳 fix: Walk subagents in the reasoning-history replay gate The gate only checked the primary agent and top-level handoff/parallel configs, so an opted-in custom endpoint used solely as a nested subagent had its persisted reasoning dropped on later turns. New exported anyAgentReplaysReasoningContent walks subagentAgentConfigs (cycle-safe, mirrors anyAgentHasCodeEnv); client.js uses it. Addresses Codex finding.	2026-06-23 21:08:47 -04:00

Danny Avila	5eb1c2c107	🖇️ feat: Reference Selected Chat Text with Multi-Quote Popup (#13868) ... * 🖇️ feat: Reference Selected Chat Text with Multi-Quote Popup Add a ChatGPT/Codex-style quote feature: selecting text in any message shows an 'Add to chat' popup that accumulates removable quote chips above the composer. On submit, the excerpts are merged into the user message text as Markdown blockquotes (counted in the user message token count, not a system message) and persisted on the message so they render on the user bubble and survive reload. - packages/api: add getReferencedQuotes + mergeQuotedText helpers (blockquote merge, length/count caps) with unit tests - BaseClient.sendMessage: temporarily merge req.body.quotes into userMessage.text before buildMessages, restore clean text, persist quotes array - data-schemas + data-provider: add optional quotes field to message schema/type - client: pendingQuotesByConvoId atom, QuoteButton selection popup, PendingQuoteChips composer row, MessageQuotes persistent display - useChatFunctions: drain pending quotes onto the message, carry forward on regenerate - add localization keys and component/integration tests * 🧪 test: Add Playwright e2e for chat quote feature Add e2e/specs/mock/quotes.spec.ts covering select -> 'Add to chat' popup -> chip -> send -> persistent reference block -> reload, plus multi-select accumulation and chip removal. Selection is driven programmatically (real DOM Range + dispatched mouseup) to summon the popup deterministically. Add data-testid hooks (add-to-chat-button, pending-quote-chips, message-quotes) to the quote components for stable selectors. * 🛡️ fix: Address Codex review on quote feature - Run PII filter + OpenAI moderation over req.body.quotes (P1): quoted excerpts are merged into the model-facing user message, so they must clear the same filters; a crafted quotes payload could otherwise bypass them. Adds tests. - Carry quotes through edit/save-and-submit replays (overrideQuotes in EditMessage), mirroring overrideManualSkills, so edited turns keep context. - Hide the quote UI for Assistants endpoints (which bypass BaseClient merge), so users can't queue quotes the assistant never receives. - Clear pending quote/skill queues by resolved conversationId in useClearStates, not the UI index, so queued-but-unsent selections don't linger in Recoil. - Cap queued quotes client-side at 10 to match the backend QUOTE_MAX_COUNT, so the composer never shows more quotes than are actually sent. * 🧵 fix: Durably re-merge quotes + Codex round 2 Address Codex's re-review of the quote feature: - Durable history re-merge (per maintainer decision): quotes are no longer merged at request time and stripped; instead each user message's persisted message.quotes is merged into its formatted content in AgentClient.buildMessages (new prependQuotes helper) for current AND historical turns. The model receives the referenced context on every prompt and the token count stays consistent with what was persisted; stored text stays clean for display. - Attach normalized quotes to the user message in handleStartMethods (before getReqData/onStart) so the optimistic bubble, resumable abort metadata, and saved row all carry them (fixes the abort-metadata gap). - Skip the quote drain entirely for Assistants endpoints in useChatFunctions, leaving the pending atom intact (UI is already hidden there). - Normalize req.body.quotes via getReferencedQuotes before moderation/PII so only the trimmed/truncated/capped excerpts the model will receive are checked. - Tests: prependQuotes unit tests; BaseClient quote tests assert early attachment + clean text; e2e now verifies the model receives the merged blockquote on the current turn and re-merged from history on a later turn (new E2E_ASSERT_QUOTE mock marker). * 🔗 fix: Quote share/memo/abort/PII gaps (Codex round 3) - Shared links: include quotes in the anonymized projection + SharedMessage type (+test) so the /share view renders the same reference blocks as the owner, mirroring manualSkills/alwaysAppliedSkills. - MessageRender memo: compare quotes length so a server/resume copy whose only change is the quote list re-renders (the block no longer goes stale/missing). - Resumable job metadata: include quotes in the userMessage written to GenerationJobManager so a reload/reconnect mid-stream reconstructs the chips. - PII + moderation: also scan the merged blockquote+text exactly as the model receives it, so a secret split across a quote and the typed body (each clean alone) is caught (+cross-boundary test). - e2e: make quote-add robust against the auto-scroll-dismisses-selection race via a retried select+click helper. * 🛑 fix: Keep quotes on aborted turn's request message (Codex round 4) abortMiddleware reconstructs finalEvent.requestMessage from jobData.userMessage but only copied ids + text; include quotes so a stopped quoted turn keeps its MessageQuotes in the UI and a regenerate-before-reload still sends the referenced context. Completes the resumable-metadata fix from the prior round. * 🧮 fix: Quote recount + preliminary abort metadata (Codex round 5) - Force a canonical token recount for messages carrying quotes in AgentClient.buildMessages, so a plain text-only Save edit (which recomputes tokenCount from text alone) can't leave a stale, quote-excluding count that undercounts context on later turns — recount from the quote-merged copy self-heals it. - Seed normalized quotes into the preliminary userMessage metadata (getPreliminaryUserMessage), so an abort during init/tool-loading (before onStart) still reconstructs the stopped turn's MessageQuotes. * ✅ fix: Add getReferencedQuotes to controller test mocks (CI) request.js's getPreliminaryUserMessage now calls getReferencedQuotes; the agents controller specs mock @librechat/api wholesale, so the mock must export it or the call throws and cascades. Added a faithful mock (normalize/cap, null when empty) to request.resumeMetadata.spec.js and jobReplacement.spec.js. * 📐 fix: Quotes in context projection + resumable metadata (Codex round 6) - Context-usage projection (resolveContextProjection): select message.quotes, prepend them into the projected user text, and recount quoted messages so the context gauge counts the same prompt the model receives (a text-only Save edit no longer makes the gauge undercount / over-report remaining budget). - Resumable job metadata: trackUserMessage (created-event rewrite) and abortJob (final requestMessage) now carry quotes; SerializableJobData.userMessage and CreatedEvent.message gained an optional quotes field. With the cross-replica created-event spread, stopping/reconnecting a quoted turn after the created event keeps its MessageQuotes. * 💬 feat: Collapse multi-select quotes into one chip with hover popup Composer feedback: the quote chip area now shows a single chip — the excerpt text for one selection, or a collapsed "{n} selections" pill for multiple, with a hover popup (HoverCard) listing every excerpt and a per-item remove. The chip is taller (py-1.5/text-sm) to read less skinny. Adds com_ui_quote_selections and com_ui_remove_all_quotes; updates unit + e2e tests (e2e drives the count via a data-quote-count hook and exercises the hover popup). * ♿ fix: Make multi-selection quote popup keyboard accessible The collapsed "{n} selections" pill used a HoverCard, which Radix only opens on pointer hover — its interactive content was unreachable by keyboard. Replaced it with a Popover: the trigger is a real button that opens on click / Enter / Space (focus moves into the list, each excerpt's × is tab-navigable, Escape closes and restores focus), with hover-open preserved for mouse via controlled open state + a close grace period. Hover-initiated opens skip auto-focus so they don't pull focus off the composer. Adds an e2e asserting keyboard open/close. * 📐 fix: Clamp the Add-to-chat button within the viewport (Codex round 7) The floating selection button positioned via translate(-50%,-100%) (bottom-center anchor) but clamped top/left as if they were its top-left, so a selection near the viewport top or sides could render the button partly/fully offscreen. Now it measures the button (ref + useLayoutEffect) and computes an on-screen top-left — clamping by the full width within side margins and flipping below the selection when there's no room above — with no transform, and stays hidden until measured so it never flashes at an unclamped spot. * ↩️ fix: Restore pending quotes on early-abort draft (Codex round 8) When a turn is stopped before the created event (e.g. during tool/MCP init), the final handler restores requestMessage.text to the draft, but the pending-quote atom was already drained on submit — so a retry sent no quotes. The abort requestMessage now carries quotes (preliminary metadata + abort fixes), so the three early-abort/no-response draft-restore paths in useEventHandlers now also re-queue pendingQuotesByConvoId from requestMessage.quotes. * ♿ fix: Use Ariakit Popover for quote selections (keyboard focus) The multi-selection popup used a hand-rolled Radix Popover with Popover.Anchor + a manual button, so Radix had no trigger to return focus to — Escape dumped focus to the page top. Refactored to Ariakit (the codebase's popover primitive, per DropdownPopup/Fork): the `PopoverDisclosure` is the real trigger, so Escape closes and returns focus to the composer instead of the top of the page. Keyboard opens (Enter/Space) autofocus into the list and tab through each excerpt's remove; hover opens for mouse with autofocus suppressed so it never pulls focus off the composer. e2e asserts the keyboard open/navigate/Escape flow keeps focus on a real control (never BODY).	2026-06-21 08:33:11 -04:00
Danny Avila	e515063ffe	🔗 feat: Snapshot Files for Shared-Link Attachments (#13740) ... * 🔗 feat: Snapshot Files for Shared-Link Attachments Shared-link viewers could read a shared conversation snapshot but not its attachments: file preview/download still went through the owner-scoped file ACL (the /api/files router sits behind requireJwtAuth + owner/agent checks), so anonymous viewers got 401s and authenticated non-owners got 403s — the repeated `[fileAccess] denied` warnings seen for the preview poller. Capture an immutable per-share file snapshot (embedded on the SharedLink document, referencing the original stored object — no byte copy) at share create/update, and serve those files through new share-scoped routes authorized by the existing shared-link view permission (public/ACL) plus snapshot membership, never the owner's live file ACL. - data-schemas: fileSnapshots on the share doc; capture in create/update; read-time rewrite of filepath/preview to /api/share/:id/files/:fileId; getSharedLinkFile + lazy backfillSharedLinkFiles for legacy links - api: GET /api/share/:shareId/files/:file_id[/download|/preview]; route context added to fileAccess denial logs - packages/api: isFileSnapshotEnabled resolver (env + yaml) - data-provider: interface.sharedLinks.snapshotFiles (default on) + client endpoints/services - client: ShareContext.shareId wired to Image, preview hook, and downloads - config: SHARED_LINKS_SNAPSHOT_FILES env override (default on) * 🔒 fix: Address Codex review on shared-link file snapshots Triage of the Codex review on PR #13740 (2 P1, 7 P2 — all valid): - P1 (cross-user access): scope the snapshot lookup to the sharing user's own files so a message referencing another user's file_id can't widen access. - P1 (stored XSS): the inline share-file route now serves only safe preview types inline (raster images/pdf); everything else is forced to attachment with X-Content-Type-Options: nosniff. - Stream shared downloads by default; redirect to a signed URL only on ?direct=true (blob/XHR callers work without bucket CORS). - Read preview status live from the file record (always current for deferred previews) and stop embedding extracted text in the share doc (16MB-limit risk). - Only lazily backfill when the fileSnapshots field is absent (legacy), not on every snapshot miss. - Backfill legacy shares before rewriting message URLs, and gate URL rewriting to public shares so non-public (ACL) shares keep prior behavior (img/anchor can't carry the bearer token). - Frontend: only route a download through the share path when the file was actually snapshotted (rewritten href / filepath), else fall back. * 🔑 feat: Authorize shared-link files for non-public shares via cookie Extends shared-link file access to non-public (ACL) shares (Codex finding 5). `<img>`/anchor requests can't carry the bearer access token, so non-public shares previously 401'd on file loads. Add an optional cookie-auth fallback on the share file routes that resolves the viewer from the `refreshToken` cookie (or signed `openid_user_id` cookie) — the same mechanism secure image links use (validateImageRequest) — then let canAccessSharedLink run the viewer's ACL check. - new middleware optionalShareFileAuth (+ unit spec); applied to the three share file routes after optionalJwtAuth - URL rewriting in getSharedMessages is no longer gated to public shares (the route now authorizes header-less requests), so files work uniformly across public and non-public shares; revert the now-unused req.sharePublic plumbing * 🔒 fix: Second Codex pass on shared-link file snapshots Addresses the follow-up Codex findings on PR #13740: - Don't snapshot transient text-source files: FileSources.text filepaths are Multer temp paths the upload route deletes, so they can't be streamed — removed from the streamable allowlist. - Unset stale snapshots on a disabled-feature update: updateSharedLink now $unsets fileSnapshots when snapshotFiles is false, so an opted-out update can't keep serving file ids the update dropped. - Load tenant config after share resolution: configMiddleware now runs after canAccessSharedLink (which enters the share's tenant ALS context), so per-tenant interface.sharedLinks.snapshotFiles overrides apply to anonymous public views. - Return a clean 404 when the snapshotted object is gone: resolveShareFile now requires the live file record and 404s if it's been deleted/expired, instead of letting the stream error after headers are sent (ENOENT / 500). (The re-flagged P1 about private-viewer rewriting was already fixed in the prior commit's cookie-auth change.) * 🔒 fix: Third Codex pass on shared-link file snapshots Addresses the third Codex review pass on PR #13740: - P1: keep shared previews/files pinned to the snapshotted version. Snapshot the small previewRevision; resolveShareFile 404s when the live file's revision no longer matches (file_id reused/overwritten by a later turn), so old links can't surface post-share content — covers both preview text and streamed bytes. - Honor the toggle as a kill switch: resolveShareFile 404s when snapshotFiles is disabled, instead of only skipping backfill, so disabling stops serving already-snapshotted file URLs. - Lazy-sweep orphaned 'pending' previews to 'failed' in the share preview route (mirrors the owner route) so the client poller reaches a terminal state. - Resolve the cookie-fallback user in runAsSystem so strict tenant isolation doesn't throw before canAccessSharedLink establishes the share tenant context. * ✨ feat: Per-link "share files" checkbox for shared links Add a checkbox to the share-link dialog (checked by default) letting the user choose whether to include the conversation's files in the shared link, with copy explaining images/files won't be visible to viewers otherwise. Opting out skips snapshot creation/serving for that link. - client: ShareButton renders the checkbox gated on the new startupConfig.sharedLinksSnapshotFilesEnabled flag; state threads through SharedLinkButton into the create/update mutations as `snapshotFiles`. - data-provider: createSharedLink/updateSharedLink send `snapshotFiles` in the body; TStartupConfig gains `sharedLinksSnapshotFilesEnabled`. - api: POST/PATCH /api/share compute snapshotFiles as isFileSnapshotEnabled(req.config) && body.snapshotFiles !== false (admin gate AND per-link opt-out); config.js exposes the effective enabled flag to clients. - en locale: com_ui_share_files (+ _description). * 🐛 fix: Make the "share files" opt-out actually hide files Unchecking "share files" at creation didn't hide anything: the shared message JSON still carried each file's original (e.g. static-served) path, and because opting out only meant "no fileSnapshots field" — indistinguishable from a legacy link — getSharedMessages would backfill snapshots on first view whenever the admin feature was on, re-enabling files entirely. Fix by persisting and honoring the per-link choice: - Store `snapshotFiles` (boolean) on the SharedLink so opt-out is distinct from a legacy link; set it on create and update. - getSharedMessages computes includeFiles = adminEnabled && link not opted out; when excluded it strips files/attachments from the payload (no original-path leak) and never backfills the opted-out link. - Surface the stored choice via getSharedLink so the dialog checkbox reflects an existing link's actual setting instead of always defaulting to checked. Note: changing the checkbox on an already-created link still applies only when the link is refreshed (which regenerates the URL) — a UX follow-up. * 🔒 fix: Close remaining shared-link file opt-out leaks (Codex) Follow-up to the per-link opt-out, addressing the third Codex pass: - Honor the opt-out on the file route too: getSharedLinkFile now returns the link's `optedOut` choice; resolveShareFile 404s (and never backfills) an opted-out link, so a direct /files/:id request can't re-create snapshots. - Make read/serve viewer-independent: the gate no longer uses the viewer's resolved config (isFileSnapshotEnabled(req.config)) — it uses the link's stored choice plus a global env-only kill switch (isFileSnapshotKillSwitchActive). A viewer's own interface.sharedLinks.snapshotFiles can no longer hide a link's files. Create/update still use the creator's config to set the per-link choice. - Neutralize render URLs for non-snapshotted files: applyShareFileRoute now strips filepath/preview for any file/attachment not in the snapshot, so the owner's original (e.g. static) path can't be loaded through the share. * 🔒 fix: Harden shared-file version pinning and local path handling (Codex) - Refuse reused/overwritten file snapshots more broadly: resolveShareFile now refuses to serve when either previewRevision OR `bytes` changed vs the snapshot. `bytes` catches non-office reused outputs (e.g. code-exec same-filename images that lack previewRevision) and is stable across S3 URL refresh and the pending->ready transition. Same-size content swaps remain a best-effort gap inherent to the no-byte-copy design. - Strip cache-busting query strings before local streaming: code-output images add `?v=...` to filepath; the share route now splits it off so getLocalFileStream resolves the real filename instead of a literal `*.png?v=...` path. * 💬 fix: Clarify that file-sharing changes apply on link refresh For an already-created shared link, changing the "share files" checkbox only takes effect when the link is refreshed (which regenerates the snapshot). Add a note under the checkbox, shown only when a link already exists, so the behavior isn't surprising: "Refresh the link to apply this change — files are snapshotted when the link is refreshed."	2026-06-20 23:05:13 -04:00

Danny Avila	f76a5faa9e	📌 feat: Seed Default Pinned Tools and MCP Dropdown via Interface Config (#13865) ... * ✨ feat: Add `defaultPinnedTools` interface config for default tool & MCP pinning Adds an `interface.defaultPinnedTools` string array letting admins pin tools and the MCP servers dropdown to the prompt bar by default for all users. - Tool keys (artifacts, execute_code, web_search, file_search, skills) pin their badge via `useToolToggle`. - The keyword `'mcp'` or a configured MCP server name pins the MCP dropdown via `useMCPSelect`. - Only seeds initial state; a user's stored pin preference always wins. When unset, tools start unpinned and the MCP dropdown keeps its legacy default (pinned). Unifies the approaches from #11646 (pinnedTools) and #9251 (defaultPinMcp) into one config key. * 🐛 fix: Apply defaultPinnedTools pin once startupConfig resolves On a cold load, useToolToggle can mount before useGetStartupConfig() resolves, so defaultPinned starts false and useLocalStorageAlt eagerly persists it; its init effect never re-runs for the later config-driven default. Fresh users would then miss the admin-configured default pin whenever startup config was not already cached. Capture whether a pin preference existed before mount (pre-seed) and, once startupConfig arrives, apply the real default for users with no prior preference. Runs once and never overrides an existing stored pin, so the conservative behavior for existing users is preserved. * 🐛 fix: Preserve pin clicks made before startupConfig resolves The cold-load default-seeding effect captured the stored-pin state only at mount, so a pin toggled before startupConfig resolved was treated as no-preference and overwritten when the admin default applied. Track explicit pin toggles via a ref (set through the returned setter) and skip the default application when the user has interacted in-session — in addition to the existing stored-preference guard.	2026-06-20 13:40:10 -04:00
Tómas Pálsson	229c54c843	🪢 fix: Paginate MCP tools/list to Load All Tools (#13840) ... * 🪢 fix: Paginate MCP tools/list to load all tools MCP `tools/list` is cursor-paginated, but LibreChat only ever read the first page. `MCPConnection.fetchTools()` called `client.listTools()` once and discarded `nextCursor`, and `MCPServerInspector` — which builds the agent-facing tool registry at startup and per request — called the raw `client.listTools()` directly. Servers that paginate (e.g. an aggregating gateway exposing hundreds of tools) only ever exposed page one; tools on later pages were never registered, and invoking one returned "This tool's MCP server is temporarily unavailable." - `MCPConnection.fetchTools()` now follows `nextCursor` across pages and concatenates every page's tools, bounded by a configurable page cap (`MCP_TOOLS_LIST_MAX_PAGES`, default 50) and a repeated-cursor guard so a misbehaving server cannot loop forever. Tools already fetched are returned if a later page fails, and the no-throw error contract is unchanged. - `MCPServerInspector.getToolFunctions()` and `fetchServerCapabilities()` now route through `fetchTools()`, so the canonical startup and per-request tool registry is fully paginated too. * style: Sort MCP test imports * style: Sort mutation type imports --------- Co-authored-by: Danny Avila <danny@librechat.ai>	2026-06-20 11:04:06 -04:00

The tsdown build externalizes all bare imports, so it emitted those specifiers verbatim into `dist/index.mjs`. dayjs@1.11 ships no `exports` map, so under strict Node ESM the extensionless subpaths fail with ERR_MODULE_NOT_FOUND ("Did you mean to import 'dayjs/plugin/utc.js'?"), breaking every strict-ESM consumer that transitively imports data-provider (and data-schemas, which re-exports it) — e.g. vitest suites in downstream apps. Add the `.js` extension so the externalized imports resolve. With moduleResolution: bundler the types still resolve from the plugin `.d.ts`. Bump to 0.8.507 to supersede the broken 0.8.506 publish.

Switch both the Anthropic and Bedrock promptCacheTtl definitions to `component: 'combobox'` (DynamicCombobox → ControlCombobox), the same component Region uses: matching rounded trigger styling, an Ariakit popover (portal, no layout shift), and — as a bonus — it persists selections via setOption on custom endpoints (DynamicDropdown's custom branch is a no-op TODO).

Default is undefined so the agents SDK applies its own default (1h), letting users opt down to the legacy 5m TTL. - data-provider: schema, parameterSettings dropdown, types, bedrock picks - data-schemas: convo/preset types + mongoose defaults - api: thread promptCacheTtl into anthropic + openai(OpenRouter) llmConfig - i18n: en translation keys for label/description/default placeholder - tests: anthropic llm.spec coverage for set + unset cases * 🔧 fix: Tie Bedrock promptCacheTtl to promptCache + thread OpenRouter TTL params (Codex review) - bedrock.ts: clear promptCacheTtl whenever promptCache is off/unsupported, so an unsupported 1h is never sent on a non-caching Bedrock request - openai/llm.ts: resolve promptCacheTtl through the same defaultParams/ addParams/dropParams machinery as promptCache (via promptCacheTtlValue) so OpenRouter custom endpoints can configure/override/drop it - tests: bedrock TTL-tied-to-promptCache cases; OpenRouter TTL default/add/drop * 🎨 style: Sort imports in openai/llm.spec.ts (CI sort-imports) * ✅ test: Prove OpenRouter TTL-only selection honors promptCache default (Codex review) OPENROUTER_DEFAULT_PARAMS injects promptCache:true into defaultParams, so a TTL-only dropdown selection (promptCacheTtl set, promptCache switch untouched) still resolves caching on and forwards the TTL.

Split the steps so the (best-effort) tag-count decrement still runs before message cleanup (counts reconciled even if messages fail), while project-stats refresh runs after, matching the original ordering. * ✅ test: Add e2e coverage for bookmark counts on conversation delete Two mock-harness specs for the deleteConvos bookmark-count behavior: - Deleting the only conversation carrying a bookmark drops its count to 0. - Deleting one of two conversations that share a bookmark leaves the count at 1.

However, the point of the gradient is just to gradually make the title disappear, not the icons.

Danny Avila	fdc7e64bb7	🪙 feat: SDK-Aligned Context-Usage Projection (gauge for window-switch & snapshot-less branches) (#13801) ... * 🪙 feat: Context-usage projection — data-provider + client wiring Consumer side of the SDK-aligned context projection (agents `projectAgentContextUsage`). Adds the `/api/endpoints/context-projection` data-provider plumbing (endpoint, service, query key, `TContextProjectionRequest`) and a `useContextProjectionQuery` gated to fire only when no fresh snapshot covers the viewed branch. Wires `useTokenUsage` precedence to: live snapshot → fresh persisted snapshot (window matches the resolved one) → server projection → per-message estimate. A model/window switch marks the baked snapshot stale (its `maxContextTokens` no longer matches) and falls to the projection — closing the gauge's window-switch (G1) and snapshot-less-branch (G2) gaps. Snapshot and projection share the render-relevant fields, so they render uniformly. Backend endpoint + agents version bump land in follow-up commits. Includes the design spec (CONTEXT_PROJECTION_SPEC.md). * 🪙 feat: Context-projection backend endpoint POST /api/endpoints/context-projection → resolveContextProjection (packages/api): reconstructs the viewed branch (parent-chain walk from messageId), resolves the agent config (instructions/provider/model/maxContextTokens), reuses LibreChat's stored per-message tokenCounts as the index map (no re-tokenizing), and calls the agents SDK projectAgentContextUsage — no model call. Thin controller injects db.getMessages/db.getAgent; route mirrors /token-config. First cut targets message-windowing accuracy; tool-schema tokens are deferred to a follow-up that reuses the full initializeAgent path. * 🩹 fix: Codex review on context projection (G1 guard, IDOR, recount, summary) - Guard `currentActive` against a stale window: a model/window switch on the current branch left the live snapshot outranking the projection (G1 didn't fire). Now defers to the projection unless streaming or the window matches. - Scope branch lookups to the authenticated user (`getMessages` filter + injected `userId`) — was loading any conversation by id (IDOR). - Recount messages with no stored `tokenCount` via the tokenizer instead of charging 0, so snapshot-less/imported histories don't under-report. - Fall back (null) for already-summarized branches rather than projecting from the full raw parent chain (the next call would send summary + tail); the client's summary-baseline-aware estimate handles them until a follow-up replays the summary boundary. * 🩹 fix: Codex round 2 — drop agent load, summary marker, edit-invalidation - Stop loading agent/model-spec config server-side (closes the agent-access IDOR and the spec-prompt special-casing). Provider/model/window now come from the client-resolved request (`limits.endpoint`/model — the agent's real provider, not the `agents` endpoint, so the tokenizer is right). Agent/spec/ promptPrefix instructions are uniformly deferred to the full-fidelity follow-up. - Detect summarized branches via the live path's `metadata.summaryUsedTokens` marker (was the wrong `summaryTokenCount` field) and fall back to the summary-aware estimate. - Invalidate the projection query on in-place message edits via a branch content `revision` in the cache key (the tail id is unchanged on edit). Deferred (valid, not a regression): same-window endpoint/model switch keeps a window-matched snapshot — needs endpoint/model persisted on the snapshot, which lands with the fidelity follow-up. Smoke-tested: fits / prunes / summarized→null / no-window→null. * 🛡️ fix: make context projection strictly additive (no-regression) Revert the G1 window-match guard on the live/branch snapshot. When no explicit maxContextTokens is set (the common default), the SDK's snapshot window is reserve-derived (~0.9·(modelContext − maxOutputTokens)) while useTokenLimits resolves the raw model context — so `snapshot.maxContextTokens === resolvedMax` is false for the SAME model, and the guard would wrongly drop a valid current-branch snapshot to projection/estimate post-stream (a regression in the default case, per initialize.ts:1240-1243). The projection now activates ONLY for snapshot-less branches (G2): the precedence is live snapshot → persisted branch snapshot → projection → estimate, where the first two are byte-for-byte the prior behavior and the projection just slots ahead of the estimate. Window/model-switch (G1) detection needs the snapshot to carry its model/window and defers to the fidelity follow-up. * 🩹 fix: surface projections as estimates, not authoritative snapshots A first-cut projection carries the SDK's windowing but omits instruction/tool overhead, so rendering it as `isEstimate: false` showed a confident under-count for snapshot-less branches. Mark projection-sourced views `isEstimate: true` + `snapshotActive: false` (and drop the snapshot field) so they present as a better estimate than sumBranch — improved used/window number, estimate framing, no misleading granular breakdown with ~0 tools. Real snapshots stay authoritative.

Danny Avila	4cb35945dc	🩹 fix: Bill Anthropic Prompt-Cache Tokens Once (#13798) ... The installed @librechat/agents folds cache_creation + cache_read into Anthropic usage_metadata.input_tokens (cache-inclusive), but cacheSubsetProviders omitted anthropic, so splitUsage() took the additive branch and billed cache tokens twice — at the full input rate and again at the cache write/read rate. Verified live: a cache-read-heavy Sonnet call was overcharged 10.7x. Add Providers.ANTHROPIC to cacheSubsetProviders (single source of truth for backend billing and client usage normalization).

Danny Avila	d18d62e7c1	🪙 refactor: Reconcile Context Gauge to Actual Provider Tokens (#13780) ... * 🪙 fix: Reconcile Context Gauge to Actual Provider Tokens The context gauge could read several× too high (e.g. 213K when the real prompt was 56K) and stay there across reloads. Root cause: the SDK's calibrationRatio is `cumulativeProviderReported / cumulativeRawSent`, but a provider's server-side web search injects large fetched content into the prompt that the SDK never sent or counted — pinning the ratio at its cap (5) and multiplying every later message estimate, including post-summary ones. The gauge rendered (and persisted) that inflated estimate, never the provider's actual token count. Fix: reconcile the snapshot to the call's ACTUAL prompt tokens (input + cache), which already arrive in on_token_usage. Only messageTokens is calibration-scaled (instructions/summary are raw tiktoken), so keep those and set messageTokens to the remainder, recomputing free space. Shared `promptTokensFromUsage` + `reconcileContextUsage` in data-provider; applied server-side in buildPersistedContextUsage (reload-stable) and client-side in useUsageHandler on each primary usage (corrects at turn-end, no follow-up needed). Also drop the summary double-count from the Breakdown Messages row. Deferred (separate agents PR): the SDK over-calibration also fires summarization prematurely; fixing it needs decoupling real-content estimation from server-side injection headroom without weakening pruning-overflow safety. * 🪙 fix: Harden Token Reconciliation for Provider-less + Resume Paths Codex review on the reconciliation: - promptTokensFromUsage: when the provider is absent (custom/OpenAI-compatible payloads), fall back to the same magnitude heuristic normalizeUsageUnits uses (cache ≤ input ⇒ already included) so cached events aren't re-inflated. - Resume: backfillUsage restores a primary call's usage without replaying a live on_token_usage (Redis mode), so the live reconcile never ran and a reconnected session stayed on the inflated estimate. New reconcileBackfill reconciles the restored snapshot from the final primary call after contextHandler installs it. * 🪙 fix: Reconcile Resume Snapshot Server-Side, Not via Backfill Codex: the client reconcileBackfill scanned the resumed run's collectedUsage and applied the final primary to the latest snapshot — but on a mid-call resume that usage belongs to an EARLIER call, corrupting the restored gauge. Move the resume reconciliation server-side: GenerationJobManager.persistTokenUsage reconciles the stored contextUsage to a primary usage's actual prompt tokens as it arrives. That usage is the post-invoke truth for the call the latest stored snapshot precedes (no snapshot is captured between a call's pre-invoke dispatch and its usage), so it's correct by construction and run-matched. A mid-call resume (no usage yet) keeps the raw snapshot instead of mis-applying an earlier call's tokens; it reconciles once the call completes. Removed client reconcileBackfill; the live-path reconcile (non-resume) stays. * 🪙 fix: Guard Reconciliation Against Replays and Snapshot Races Two Codex concurrency findings on the reconciliation: - Client: reconcile only on a NEWLY folded primary usage. A replayed duplicate (folded=false on resume) can be an earlier tool-loop call sharing the run id, which would overwrite the latest snapshot with an earlier, smaller prompt. Moved the reconcile after the folded guard. - Server: serialize the context-usage write through the same per-stream queue as the token-usage write. persistTokenUsage reconciles the stored snapshot (read-modify-write); an unserialized trackContextUsage could store a newer snapshot between the read and write — or a stale reconciled write could land after a newer snapshot — clobbering the newer run's gauge when calls interleave. FIFO keeps each call's snapshot ahead of its own usage and behind the next. * chore: import order in GenerationJobManager.ts	2026-06-16 11:05:44 -04:00

Danny Avila	9efe4878e7	🅰️ feat: Native Anthropic Provider for Custom Endpoints (#13748) ... * 🅰️ feat: Native Anthropic provider for Custom Endpoints Let a custom endpoint declare `provider: anthropic` to use the native Anthropic `/v1/messages` client (the agents SDK's ChatAnthropic) against its own `baseURL`/`apiKey`/`headers`, instead of being forced through the OpenAI-compatible client. Enables Anthropic itself and Anthropic-compatible gateways (AI gateways, OpenCode Zen, etc.) as custom endpoints — including for agents and role-scoped model access. Closes #10655 (Option 1: explicit provider). - Schema: add optional `provider` (currently `anthropic`) to the custom `endpointSchema` in data-provider. - Routing: `getProviderConfig` maps a custom endpoint with `provider: anthropic` to `Providers.ANTHROPIC` (was always `Providers.OPENAI`). - Config: `initializeCustom` builds the native Anthropic config via the Anthropic `getLLMConfig` (custom baseURL/apiKey/headers) and returns `provider: anthropic`; `useLegacyContent` is left unset to match the built-in Anthropic endpoint. The OpenAI-compatible path is unchanged for endpoints without `provider`. - Summarization: `resolveSummarizationProvider` builds an Anthropic config for a cross-endpoint native-Anthropic summarization target (self-summarize already reuses the agent's client options). Title generation already resolves via `agent.endpoint`, and provider-specific handling (tool conflicts, content/PDF validation, token counting, streamUsage) already branches on `Providers.ANTHROPIC`, so it applies automatically. Note: model auto-fetch (`models.fetch`) uses the OpenAI `/models` convention and is not used for this provider — list models explicitly under `models.default`. * 🅰️ fix: Anthropic custom-endpoint param parity (Codex review) Address Codex P2 findings — the native Anthropic path must match the OpenAI-compatible path's parameter handling: - UI param set: `loadCustomEndpointsConfig` now surfaces `provider` as the client `customParams.defaultParamsEndpoint`, so the Agents model panel shows Anthropic fields (`maxOutputTokens`/`thinking`) instead of OpenAI `max_tokens` (which the native initializer ignored). An explicit non-default `defaultParamsEndpoint` still wins. - Provider override: `getProviderConfig` re-applies `provider: anthropic` after all `customEndpointConfig` resolution, so it also wins when the endpoint name collides with a known custom provider (e.g. `openrouter`) — fixing the token/context budget derived from `overrideProvider`. - Default params: the native path (and cross-endpoint Anthropic summarization) now apply `customParams.paramDefinitions` defaults via `extractDefaultParams`, matching what `getOpenAIConfig` does for the OpenAI-compatible path.

Danny Avila	2350ebb24a	📨 feat: Custom Headers on Built-in Provider Endpoints (#13742) ... * 📨 feat: Custom Headers on Built-in Provider Endpoints Add a `headers` config option to the built-in `openAI`, `anthropic`, and `google` endpoints (incl. Anthropic/Google Vertex), mirroring the custom endpoint header mechanism. Values support the same placeholder resolution (env vars, `{{LIBRECHAT_USER_*}}`, `{{LIBRECHAT_BODY_CONVERSATIONID}}`) and are resolved at request time so dynamic values like conversationId resolve against the live request — without losing provider-native request shaping. Closes #13082. Covers #13713: forwarding conversationId to a reverse proxy is now `X-Conversation-Id: '{{LIBRECHAT_BODY_CONVERSATIONID}}'` — an unknown header is ignored by the native Anthropic API, so no 400 and no metadata gating needed. - Schema: `headers` on `baseEndpointSchema` (openAI/google/anthropic/all). - New `mergeHeaders`/`resolveConfigHeaders` utils centralize the per-provider header locations (`configuration.defaultHeaders`, Anthropic `clientOptions.defaultHeaders`, Google `customHeaders`); provider-managed headers (auth, `anthropic-beta`) always win on collision. - Each initializer threads configured headers (endpoint over `all`) into the right place; request-time resolution runs across all locations in the main and title flows. * 🩹 fix: Cast endpoints.all to TEndpoint for headers DeepPartial widening Adding `headers` (a Record) to `baseEndpointSchema` makes `DeepPartial<TCustomConfig>` widen its value type to `string | undefined`, which is not assignable to the concrete `TEndpoint['headers']: Record<string, string>` at the `loadedEndpoints.all` assignment. Cast at the assignment site, mirroring the existing `anthropicConfig as TAnthropicEndpoint` cast in the same function. * 🛡️ fix: Harden built-in endpoint custom headers (Codex review) Address Codex P2 findings on the custom-headers feature: - Anthropic title requests: `omitTitleOptions` strips the `clientOptions` carrier, which dropped its `defaultHeaders`. Preserve just the header carrier so gateway/reverse-proxy metadata still reaches title generation. - mergeHeaders: match header names case-insensitively so an override (e.g. a provider-managed `Authorization`/`anthropic-beta`) replaces/uniones a case-variant from the base instead of emitting two names a client may collapse. - OpenAI: withhold admin-configured headers when the user supplies the base URL (`user_provided`), since values may carry `${SECRET}`/token placeholders that must not reach a user-controlled endpoint — mirrors the custom-endpoint guard. - Azure: honor global `endpoints.all` headers (same OpenAI carrier) while keeping Azure-managed `api-key`/version headers authoritative. Adds tests for each. * 🔐 fix: Resolve-once + provider-managed header safety (Codex review round 2) Address Codex P2 findings: - Azure: keep global `endpoints.all` headers unresolved at init and let request-time `resolveConfigHeaders` resolve them once, avoiding a second-order env expansion of already-substituted user values. - Google: `resolveConfigHeaders` no longer template-resolves the provider-managed `Authorization` header (built from a possibly user-provided key), so a user key like `${ENV}` can't leak server environment values. - Model fetches: thread configured headers (endpoint over `all`) + user object through `getOpenAIModels`/`getAnthropicModels` → `fetchModels`, so a gateway-fronted built-in provider receives the header on `/models` too. Fixed `fetchModels` to merge custom headers for Anthropic instead of overwriting them (managed `x-api-key`/version still win). Adds/updates tests for each. * 🧯 fix: Header provenance, memory/title coverage, idempotency (Codex round 3) Address Codex P2 findings, including two regressions from the prior round: - Google auth (findings 6 & 8): move native Google header resolution to init (`initializeGoogle`), resolving admin templates BEFORE the key-derived auth header is built. resolveConfigHeaders no longer touches Google `customHeaders`, so admin `Authorization` templates resolve again (fixes the round-2 regression) while the SDK auth header (possibly a user-provided key) is never env-expanded. - Memory runs: memory extraction now calls `resolveConfigHeaders`, so native Anthropic (and OpenAI) headers resolve for memory requests too. - Vertex titles: restore the ORIGINAL `clientOptions` object reference (not a copy) when preserving headers across `omitTitleOptions`, so the Vertex `createClient` closure and the resolved headers stay on the same object. - Reuse: `resolveConfigHeaders` is now idempotent (resolve-once per header map), preventing a second pass from env-expanding values already substituted with user/body data when an agent object flows through buildAgentInput twice. Adds/updates tests for each.	2026-06-14 17:02:04 -04:00
Danny Avila	7cf2877b45	🪙 feat: Context Gauge UX, Hover Snapshot, Click Breakdown, Currency, Cost-On-By-Default (#13739) ... * 🪙 feat: Default Context Cost On + Configurable Display Currency Flip interface.contextCost to default-on (schema default true, resolved per-field in loadDefaultInterface so it applies unless an admin explicitly sets false). Add interface.currency { code, rate }: an ISO-4217 code and a static USD→local multiplier so non-USD communities (EUR, JPY, CNY, BRL, ZAR, …) can show costs in their currency. Inner fields are required (no nested defaults) to keep zod input/output identical; loadDefaultInterface passes it through. Display-only — model prices stay USD server-side. * 🪙 feat: Currency-Aware Context Cost Formatting formatCost(usd, currency?) applies the static rate (usd × rate) and formats via a cached Intl.NumberFormat keyed by currency code — locale-correct symbol and per-currency decimals, falling back to USD on a malformed code. The USD default (code USD, rate 1) is byte-identical to the prior output. * 💄 feat: Gauge Hover Snapshot, Click-to-Open Breakdown, Hide Until Data Replace the hover-only HoverCard with: a compact hover snapshot tooltip ("Context 341.7k / 1.0M (34%)" + cost when enabled) via the existing Tooltip primitive, and a click-opened Ariakit popover for the full breakdown that dismisses on outside-click/Escape/blur. Gate visibility on usedTokens > 0 so a fresh, message-less chat shows nothing, with an animate-in fade as the first tokens land. Thread the display currency into the breakdown + snapshot. * 🧪 test: Gauge Interaction + Visibility E2E Switch the breakdown specs from hover to click, and add a test that the gauge is absent on a new chat, surfaces the snapshot tooltip on hover, opens the breakdown on click, and dismisses on Escape and outside-click. * 🪙 fix: Harden Currency Resolution + Layer Breakdown Above Tooltip Address Codex review on the currency display: - Unsupported currency code now falls back to USD AND rate 1, so a typo like { code: 'EURO', rate: 0.92 } no longer shows a converted amount under a $ symbol (was $9.20 for a $10 cost; now $10.00). - A non-finite/negative rate (e.g. a partial admin override that set code before rate) falls back to rate 1, so a cost never renders as NaN. - Fraction digits derive from the currency's own defaults, so zero-decimal currencies (JPY) render ¥5, not ¥5.00, and extra sub-unit precision applies only to currencies that have minor units. USD output is unchanged. - Raise the click breakdown popover to z-[200] so it always sits above the z-150 hover tooltip when both briefly coexist. * 🪙 fix: Validate ISO-4217 Codes + Derive Tiny Threshold from Minor Unit Address Codex review on currency formatting: - Intl.NumberFormat accepts any well-formed 3-letter code (EUU, RMB) without throwing, so the previous construct-based check missed typos/non-ISO codes and applied the rate under a bogus label. Validate against Intl.supportedValuesOf ('currency') (the ISO-4217 set); unsupported codes fall back to USD + rate 1. Codes are normalized to upper-case; graceful fallback if the runtime lacks supportedValuesOf. - The tiny-amount threshold now derives from the currency's minor unit (10^-fractionDigits): 0.01 for 2-decimal, 0.001 for 3-decimal (KWD/BHD/JOD), 1 for zero-decimal — instead of a hard-coded 0.01. Sub-unit precision trims to each currency's own scale. USD output unchanged.	2026-06-14 13:38:27 -04:00
Danny Avila	b03b2a0a29	💾 feat: Persist Context Breakdown & Branch/Total Usage Cost (#13734) ... * 💾 feat: Persist Context Breakdown & Branch/Total Usage Cost Persist the granular context breakdown and per-response usage/cost on the response message metadata, and re-derive branch + total usage/cost from a per-message index so the popover survives reloads and is branch-aware live. - Add aggregateEmittedUsage + buildPersistedContextUsage helpers in packages/api; capture the latest visible snapshot and every emitted on_token_usage payload via contextUsageSink/usageEmitSink. - Attach metadata.contextUsage (Part A) and metadata.usage (Part B) on the agents response message in sendCompletion. - Carry per-message usage on the token index; add sumTotalUsage/setEntryUsage and branch-scoped usage on sumBranch. - Repurpose the session accumulator into a single in-flight pending holder; flush it into the index at finalize; hydrate breakdowns on load. - Render branch cost with a conditional all-branches total in the breakdown. * 🧹 chore: Remove orphaned com_ui_session_cost i18n key * 🩹 fix: Address Codex review — normalize usage server-side, fix reload deltas - Persist per-event-normalized display units in metadata.usage (TResponseUsage) so reloaded mixed-provider turns match the live session; client reads them directly instead of re-normalizing with a single stamped provider (P2). - Persist completedOutputTokens (final call output) on metadata.contextUsage so a reloaded multi-call turn adds the post-snapshot delta, not the full tokenCount the snapshot already counts (P2). - buildIndex preserves a prior entry's immutable usage when a rebuilt cache message lacks metadata.usage, so a mid-session rebuild (regenerate) keeps a sibling branch's flushed cost (fixes the e2e regenerate failure). - Track costKnown so turns saved with contextCost off don't render $0.00 when cost display is later enabled (P3). - Use an epsilon for the all-branches cost comparison to avoid a spurious total row from float summation order (P3). - Update unit/integration/e2e tests for the new shapes; regenerate e2e asserts the all-branches total after reload (deterministic via persisted metadata). * 🩹 fix: Address Codex round 2 — pending leak, cost coverage, reload delta - Clear the in-flight pending usage on terminal abort/error (resetLive), so a stopped generation's tokens no longer merge into the next response (P2). - costKnown now means COMPLETE coverage (ANDed): a branch mixing cost-bearing and cost-less turns is flagged incomplete and the cost row is hidden rather than rendering an under-reported total (P2). - Drop the tokenCount fallback for completedOutputTokens on reload: only the persisted post-snapshot delta is used, so a multi-call turn whose provider emitted no usage_metadata no longer double-counts earlier output (P2). - Update tokens.spec for AND coverage semantics + incomplete-cost case. * 🩹 fix: Address Codex round 3 — no-usage snapshots, total coverage, provider-less cache - Skip persisting metadata.contextUsage when the response emitted no primary usage event: without a known post-snapshot output the granular gauge would undercount the reply on reload, so fall back to the coarse per-message estimate instead (P2). - Gate the all-branches cost row on totalUsage.costKnown so an incomplete total (a sibling saved without cost) never renders an under-reported figure (P2). - aggregateEmittedUsage/finalCallOutputTokens now normalize per-event with the client's magnitude fallback (normalizeEventUnits) instead of billing splitUsage, so provider-less cached events match live on reload (P2). - Add backend test for the provider-less cached case. * 🩹 fix: Address Codex round 4 — abort attribution, complete cost coverage - aggregateEmittedUsage persists cost only when EVERY call was priced; a partial pricing failure now omits cost so the client treats coverage as unknown rather than reading an under-reported sum as authoritative (P2). - finalizeUsage flushes pending into the response entry only when events were folded this session (eventCount > 0), so a late/second resumable subscriber carrying persisted metadata.usage keeps it instead of being overwritten with an empty pending record (P2). - On user stop, attribute the in-flight pending usage to the partial response (new attributePending handler) instead of discarding it in resetLive — the stopped reply's billed tokens are kept and still can't leak into the next response; resetLive's discard remains for the error path (P2). * 🐛 fix: Persist branch cost across branch switches via sticky usage history Branch cost vanished on switching to a sibling branch (until a new turn) — the cost analog of the granularity bug. buildIndex rebuilds the token index from the messages cache; a sibling generated this session whose cache message lacks metadata.usage (and is transiently dropped from the cache during regenerate) lost its live-flushed usage, so sumBranch found none and the cost row hid. Fix: a sticky per-response usage map (conversationId → messageId → usage), written by setEntryUsage and never rebuilt from the cache — the usage counterpart of snapshotsByAnchorFamily for the breakdown. buildIndex/upsertEntries restore an entry's usage from it when the message carries none; cleared on convo switch and migrated with the index. Add unit coverage for the drop-then-readd regression and an e2e assertion that branch cost survives a branch switch. * 🐛 fix: Re-index on branch switch so branch cost survives the switch The sticky usage history alone didn't fix the reported branch-switch cost drop: on a branch switch no cache `updated` event fires, so the index subscriber never re-ran, and the post-regenerate rebuild was skipped while `isSubmitting` was still true — leaving the index stale and missing the now-viewed branch's response entirely (sticky can only restore entries present in a rebuild). Re-index from the messages cache on every tail change (created/finalize AND branch switch), not just while submitting. The cache holds the full message set at switch time, so the viewed branch's response is re-added and its usage restored from metadata.usage or the sticky history → sumBranch finds it and the branch cost renders. Verified locally: the branch-switch e2e now passes (the cost section shows both the branch row and the all-branches total). Also fixed that e2e assertion to target a single cost value (strict-mode safe). * 🩹 fix: Handle stopped-stream usage — reset pending + persist abort metadata Codex round (stop/abort edges): - Resumable explicit-stop (intentional SSE close) reset UI state but never cleared pendingUsageFamily, so usage folded before the stop leaked into the next response in the conversation. Discard pending on intentional close (resetLive); a resume re-folds via backfillUsage, so nothing is lost. - The abort save path (abortMiddleware) persisted the stopped response without metadata.usage/contextUsage, so its cost + breakdown vanished on reload. Rebuild both from the job's persisted tokenUsage (emitted payloads incl. cost) and contextUsage snapshot — parity with the normal sendCompletion path; breakdown gated on a primary usage event like buildResponseMetadata. Deferred (per scope decision): mid-stream branch-switch transiently shows the streaming branch's pending on the viewed sibling (cosmetic, until finalize). * 🩹 fix: Persist abort metadata on the real agents route + tighten snapshot gate Codex round (corrects last round's wrong-path fixes): - Stopped AGENTS responses are saved by routes/agents/index.js (/chat/abort), not abortMiddleware — so last round's metadata fix never ran for them. Moved the rollup/snapshot builder into packages/api as buildAbortedResponseMetadata (shared, unit-tested) and applied it in BOTH abort save paths, so a stopped agent reply keeps its cost + breakdown on reload. - Persist the breakdown only when the FINAL visible call emitted usage: track a per-response snapshot count and require primaryUsageCount >= snapshotCount. Previously any earlier primary usage event passed the gate, so a multi-call turn whose final call emitted no usage_metadata used an earlier call's output as completedOutputTokens (already counted by the latest snapshot) → reload over-reported. Now it falls back to the coarse estimate. Resumable stop pending-reset (prior round, 3cde6fe035) already flows through clearAllSubmissions → SSE close → the intentional-close handler's resetLive. Deferred per scope: mid-stream branch-switch pending attribution (tracked). * 🩹 fix: Abort breakdown over-count + resume re-fold after pending discard Codex round (on the re-applied abort/snapshot work): - buildAbortedResponseMetadata now persists ONLY the usage/cost rollup, not the context breakdown. The abort path can't tell whether the final call emitted usage (the job stores only the latest snapshot, not a count), so persisting the breakdown risked reusing an earlier call's output as completedOutputTokens (already in the snapshot) → reload over-count. Stopped/incomplete responses now fall back to the coarse gauge estimate, which is safe and apt. - resetLive now also forgets the conversation's folded usage-event identities (clearUsageFolded). Discarding pending on a terminal/intentional close left the folded keys set, so a later resume's backfillUsage saw the persisted events as duplicates and never rebuilt pending — leaving the response's usage missing until a full reload. Clearing them lets the resume re-fold.	2026-06-14 10:48:07 -04:00
Danny Avila	db7011d567	📊 feat: Real-Time Context Window & Token Usage Tracking (#13670) ... * 📊 feat: Real-Time Context Window & Token Usage Tracking * 🧪 fix: Align Pricing Spec Dep Signatures with TxDeps * 🩹 fix: Resolve Codex Findings for Context Usage Tracking * 📊 feat: Granular Tool Token Breakdown with Deferred Splits * 🧪 test: Cover Session Cost in Mock E2E and Scope Usage Selectors * 🧪 test: Live Host-Pipeline Usage Verification (Env-Gated) * 🧪 test: Local Real-Provider Multi-Turn E2E Harness * 🪙 fix: Keep Tagged Usage Buckets Out of the Live Context Estimate * 🩹 fix: Scoped Token-Config Fallback and Sequential Visibility for Usage Events * 🩹 fix: Address Usage Review Findings — Cost Timing, Scoped Caches, Finalized Output - carry the post-snapshot output estimate into the context snapshot at finalize so the gauge keeps the last response after live resets - accumulate per-rate billable units and price the session cost at render, so usage events arriving before the token-config load still count once it resolves - pass user-scoped token-config cache keys through loadConfigModels fetches and drop the controller's unscoped fallback to prevent serving another user's resolved config - tag emitted usage events with a per-run seq so resume dedupe never drops a distinct call with an identical payload - admit the static tokenConfig override in the custom endpoint schema so it survives zod parsing into req.config * 🩹 fix: Align Client Usage Accounting with Backend Cost Semantics - classify cache tokens by provider (shared inputTokensIncludesCache from data-provider, consumed by both the backend billing path and the client) instead of a magnitude heuristic, so Anthropic/Bedrock turns where cache is smaller than uncached input no longer under-bill input - mirror resolveCompletionTokens on the client so Vertex-style hidden thinking tokens are reflected in the Output row and session cost - prefer endpoint pricing over adapter-provider pricing so a custom endpoint can price a known model name without built-in rates shadowing it - carry static cacheRead/cacheWrite overrides through the tokenConfig schema and buildTokenConfigMap * 🩹 fix: Honor Static Token Config in Billing; Tighten Usage Freshness - initializeCustom now uses a static endpoint tokenConfig as the agent's endpointTokenConfig (billing + balance checks), not just the advertised UI config — previously the gauge showed admin rates while the agent billed against built-in tables - invalidate the token-config query alongside models on user-key add/ revoke so context windows and pricing refresh without a reload - include maxContextTokens in ChatForm's stabilized conversation memo so the gauge reflects a changed context-window setting immediately - feed the live output estimate from the legacy content path (direct and assistants streams), setting from cumulative part text rather than accumulating deltas * 🩹 fix: Resume Usage Dedup, Agent Pricing, and Partial Override Billing - fold usage events idempotently by (runId, seq) so resume backfill no longer resets the conversation totals — a mid-stream reconnect keeps the usage of prompts already completed earlier in the session - tap replayed pending message/reasoning/content events so output streamed past the resume snapshot reaches the live estimate, not just the message - resolve cost against the agent's backing endpoint (Agents conversations report endpoint `agents` / provider `openAI`, neither of which keys a custom endpoint's tokenConfig) - getMultiplier/getCacheMultiplier fall back to the standard tables for models absent from a partial endpointTokenConfig, so a partial static override no longer bills non-listed models at defaultRate while the UI shows the correct pattern rate * 🩹 fix: Repaired Output in Gauge, Cache-Rate Keys, Config Gate, Usage Cleanup - live/completed gauge counts the repaired completion (normalized output), so under-reporting providers don't drop the response from used context - translate static tokenConfig cacheWrite/cacheRead onto the write/read keys getCacheMultiplier reads, so cache tokens bill at the configured rate instead of the prompt-rate fallback - clear the token index and usage atoms when leaving a conversation, so visited histories don't accumulate in memory for the tab's lifetime - wait for startupConfig before mounting the gauge, so a deployment with contextUsage disabled never briefly mounts it or fires the token-config query on first load * 🩹 fix: Move Token-Config Resolution to TS; Key Live Usage by Created Convo - extract the token-config resolution (override gathering + cache lookup + buildTokenConfigMap) into resolveTokenConfigMap in packages/api, leaving the /api controller a thin request-scoped wrapper (CLAUDE.md TS rule) - getConvoKey prefers the user message's real conversationId once the `created` event stamps it, so a new chat's first-response live gauge and totals land under the id TokenUsage subscribes to instead of NEW_CONVO * 🩹 fix: Clear Stale Redis Job Usage; Live-Tap Legacy Streams; Share Fetched Config - DEL the Redis job hash before re-creating it so a reused streamId can't inherit a prior run's contextUsage/tokenUsage and backfill stale usage - tap the legacy {message,text} stream branch (non-agent OpenAI/Anthropic streams) into the live estimate, not just the content path - copy a deduped fetch's token config to every sibling endpoint sharing the baseURL/key/headers, so /token-config resolves each by its own name * ⏪ revert: Don't DEL Redis job hash in createJob (breaks cross-replica resume) createJob is an idempotent join — a second replica calls it for the same streamId to share an in-flight stream's state. DELeting the hash wiped the prior replica's persisted created/usage state, so a joining replica missed the created event (GenerationJobManager cross-replica integration test). Reverts the F1 change from 2bfce0c34b; the stale-usage concern doesn't arise in practice (streamId is unique per generation). * 🩹 fix: Best-Effort Usage Emit; Tag Hidden Sequential-Agent Usage - wrap the ModelEndHandler usage emit in try/catch so a failed telemetry delivery (closed SSE / Redis publish error) can't abort the handler before thought-signature capture, which would break resumed tool calls - tag hidden sequential-agent usage as 'sequential' (non-primary) so the client folds it into session cost/totals but not the live context gauge, instead of letting an undefined usage_type inflate the visible gauge * 🩹 fix: Refetch Stale Token Config on Mount; Normalize Vertex for Lookup - useTokenConfigQuery refetches on mount when stale, so a user-key change that invalidates tokenConfig while the gauge is unmounted takes effect on return instead of serving the prior key's resolved config - normalize a Vertex-backed agent's provider (vertexai) to the google token-config key, so Gemini context windows and rates resolve instead of showing unknown context / $0 cost * ✨ feat: Server-Side Per-Event Cost (Authoritative Pricing for the Gauge) Move usage-cost pricing to the single source of truth. The backend prices each model call with the same billing functions (premium tiers via getMultiplier(inputTokenCount), cache rates) and emits the USD cost on on_token_usage when interface.contextCost is enabled; the client sums emitted costs instead of re-deriving from base token-config rates. - computeUsageCostUSD reuses prepareTokenSpend/prepareStructuredTokenSpend so the emitted cost matches what is billed (incl. premium thresholds) - getDefaultHandlers gains a usageCost pricing context; initialize.js wires db.getMultiplier/getCacheMultiplier gated on contextCost (agents path) - client UsageTotals carries a summed costUSD; retire the client-side rate lookups (costFromUnits/calcUsageCost) that drifted from backend pricing and produced the provider-keying / cache-key / Vertex / premium findings - keep normalizeUsageUnits for the displayed token counts; token-config is still used for the context-window meter Fixes the premium-tier session-cost under-report (gpt-5.x / gemini-3.1 above their input thresholds). * 🩹 fix: Branch-Accurate Usage Snapshot + Clearer Gauge Track Contrast - re-anchor the context snapshot from the user message to the response message at finalize. Regenerating a response branches off a shared user message, so anchoring on it made the snapshot read as "active" on both branches — switching to the sibling branch showed the wrong (other branch's) context. The response message is branch-unique, so sibling branches now correctly fall back to their own per-branch totals. - raise the gauge ring's track/fill contrast (muted track, prominent fill) so the used portion reads clearly as a fill-level indicator * 🩹 fix: Tag Sequential Usage in Billing; Emit Subagent Cost; Reset Live on Resume Errors - tag hidden sequential-agent usage `usage_type: 'sequential'` on the COLLECTED usage (not just the emit), and treat it as non-primary in recordCollectedUsage (billed, excluded from the reported output total) so hidden intermediate output stops inflating the parent's tokenCount/pruning - emit on_token_usage from the subagent usage sink (tagged `subagent`, with authoritative cost when contextCost is on) so the gauge's session cost/totals include billed subagent usage; it stays out of the live meter - call resetLive on the resumable 404 and max-retry terminal branches so the gauge doesn't keep counting stale in-flight tokens after the stream ends * 🎨 fix: Contrast the Popup Context Bar; Revert Ring Restyle - raise the popup breakdown's context progressbar contrast (muted surface-tertiary track, prominent text-primary fill) — that's the bar the contrast feedback was about - revert the gauge ring restyle (kept its original border-heavy track / text-secondary fill); the ring wasn't the element in question * 🩹 fix: Stop Snapshot Granularity Leaking Across Branches; Revert Tree Memo - a null-anchor context snapshot was treated as active on every branch, leaking one generation's granular breakdown onto sibling branches. Require a non-null (response-message) anchor on the viewed branch instead, so siblings without a matching snapshot fall back to their own totals. - revert the buildTree WeakMap memo in messages.ts. buildTree is pure (builds from shallow copies) so the memo was behaviorally identical, but it was the feature's only change to core branch-navigation selectors — removing it matches upstream and rules it out of branch-navigation debugging. * 🪙 fix: Thread Endpoint Token Config to Agent Billing, Cost, and Context Limits Custom-endpoint agents resolve an endpointTokenConfig during agent init but it never reached the AgentClient, so spending, emitted cost, and runtime max-token resolution all fell back to default rates for those agents. - Surface options.endpointTokenConfig on the returned InitializedAgent. - Pass it to the AgentClient (this.options.endpointTokenConfig) so the spending path bills at configured rates. - Thread it through usageCost to computeUsageCostUSD so emitted per-event cost matches billing. - getModelMaxTokens/getModelMaxOutputTokens fall back to the built-in map for models absent from a partial override (matches buildTokenConfigMap); consolidates the duplicated fallback in pricing.ts. * 🪙 fix: Preserve Granular Breakdown Across Branch Switches The granular context breakdown lives only in the live on_context_usage snapshot — a single per-conversation slot, anchored to the latest response and overwritten by each generation. Switching to a branch generated earlier this session lost its tool/skill/system rows and fell back to coarse totals. Retain each generation's finalized snapshot in a per-conversation map keyed by its branch-unique response id (snapshotsByAnchorFamily). When the live snapshot is off the viewed branch, walk the branch tail for its deepest stored anchor and render that breakdown. Bounded by generation count and cleared on conversation switch; the live/just-generated path is unchanged. * 🪙 fix: Harden Resume Seeding and Subagent Usage Emission - useResumableSSE: skip the trailing-output live seed when the resume carries a context snapshot; the snapshot's messageTokens already counts produced output, so seeding it again inflated usage until the next reset. - AgentClient subagent emitter: await GenerationJobManager.emitChunk like every other caller (it persists before publishing), so a floating promise can't race job cleanup and a Redis/publish failure is caught by the emitter's try/catch instead of surfacing as an unhandled rejection. * 🧪 test: Playwright Coverage for Context Breakdown Granularity Add a test-only data-testid distinguishing the granular snapshot breakdown (context-breakdown) from the coarse message-history estimate (context-estimate), then assert granularity in the mock e2e harness: - renders the granular breakdown from the live on_context_usage snapshot (guards that the snapshot event actually reaches the popover, not just the usage totals). - preserves the granular breakdown after switching branches — regenerate to overwrite the single live snapshot, switch back, and confirm the rows survive via the per-anchor snapshot history map. Branch regenerate/sibling selectors mirror the existing chat.spec branch test. All three usage specs pass against the mock pipeline. * 🪙 fix: Correct Resume Live-Seed, Fallback Re-index, and Subagent Emit Flush Codex round on the prior commit: - countTrailingOutputChars now counts only output at the very END of the aggregated content (0 when the model paused at a tool call), and the resume path always seeds it. The earlier skip-trailing-tool-parts behavior plus the skip-seed-when-snapshot gate together over- or under-counted in-flight output on resume; one rule fixes both — pre-invoke snapshot budget is never double-counted, and genuine in-flight output is no longer dropped. - useTokenUsage re-indexes from the messages cache on tail change while submitting. The cache subscriber is muted during streaming, so without a context snapshot (non-agent streams) sumBranch missed the created tail and dropped history + prompt until finalize. Bounded — tailId only shifts on created/finalize/branch-switch. - AgentClient tracks subagent usage emit promises and flushes them in chatCompletion's finally. The sink fires the emitter without awaiting, and resume reads the usage emitChunk persists (HSET), so cleanup must not race it or resumed clients miss billed subagent usage.	2026-06-13 19:38:28 -04:00
