refactor(agents): import getProviderConfig from @librechat/api
chore: code order
feat(app-config): auto-enable summarization when configured
feat: summarization config
refactor(summarization): streamline persist summary handling and enhance configuration validation
Removed the deprecated createDeferredPersistSummary function and integrated a new createPersistSummary function for MongoDB persistence. Updated summarization handlers across various controllers to utilize the new persistence method. Enhanced validation for summarization configuration to ensure provider, model, and prompt are properly set, improving error handling and overall robustness.
refactor(summarization): update event handling and remove legacy summarize handlers
Replaced the deprecated summarization handlers with new event-driven handlers for summarization start and completion across multiple controllers. This change enhances the clarity of the summarization process and improves the integration of summarization events in the application. Additionally, removed unused summarization functions and streamlined the configuration loading process.
refactor(summarization): standardize event names in handlers
Updated event names in the summarization handlers to use constants from GraphEvents for consistency and clarity. This change improves maintainability and reduces the risk of errors related to string literals in event handling.
feat(summarization): enhance usage tracking for summarization events
Added logic to track summarization usage in multiple controllers by checking the current node type. If the node indicates a summarization task, the usage type is set accordingly. This change improves the granularity of usage data collected during summarization processes.
feat(summarization): integrate SummarizationConfig into AppSummarizationConfig type
Enhanced the AppSummarizationConfig type by extending it with the SummarizationConfig type from librechat-data-provider. This change improves type safety and consistency in the summarization configuration structure.
test: add end-to-end tests for summarization functionality
Introduced a comprehensive suite of end-to-end tests for the summarization feature, covering the full LibreChat pipeline from message creation to summarization. This includes a new setup file for environment configuration and a Jest configuration specifically for E2E tests. The tests utilize real API keys and ensure proper integration with the summarization process, enhancing overall test coverage and reliability.

Updated the formatAgentMessages function to return an initial summary alongside messages and index token count map. This change is reflected in multiple controllers and the corresponding tests, enhancing the summarization process by providing additional context for each agent's response.
refactor: move hydrateMissingIndexTokenCounts to tokenMap utility
Extracted the hydrateMissingIndexTokenCounts function from the AgentClient and related tests into a new tokenMap utility file. This change improves code organization and reusability, allowing for better management of token counting logic across the application.
refactor(summarization): standardize step event handling and improve summary rendering
Refactored the step event handling in the useStepHandler and related components to utilize constants for event names, enhancing consistency and maintainability. Additionally, improved the rendering logic in the Summary component to conditionally display the summary text based on its availability, providing a better user experience during the summarization process.
feat(summarization): introduce baseContextTokens and reserveTokensRatio for improved context management
Added baseContextTokens to the InitializedAgent type to calculate the context budget based on agentMaxContextNum and maxOutputTokensNum.

This enhancement allows for better tracking and debugging of agent interactions by logging messages with associated metadata. Updated the summarization process to ensure proper handling of log events.
fix: remove duplicate IBalanceUpdate interface declaration
perf(usage): single-pass partition of collectedUsage
Replace two Array.filter() passes with a single for-of loop that
partitions message vs. summarization usages in one iteration.
fix(BaseClient): shallow-copy message content before mutating and preserve string content
Avoid mutating the original message.content array in-place when
appending a summary block. Also convert string content to a text
content part instead of silently discarding it.
fix(ui): fix Part.tsx indentation and useStepHandler summarize-complete handling
- Fix SUMMARY else-if branch indentation in Part.tsx to match chain level
- Guard ON_SUMMARIZE_COMPLETE with didFinalize flag to avoid unnecessary
re-renders when no summarizing parts exist
- Protect against undefined completeData.summary instead of unsafe spread
fix(agents): use strict enabled check for summarization handlers
Change summarizationConfig?.enabled !== false to === true so handlers
are not registered when summarizationConfig is undefined.
chore: fix initializeClient JSDoc and move DEFAULT_RESERVE_RATIO to module scope
refactor(Summary): align collapse/expand behavior with Reasoning component
- Single render path instead of separate streaming vs completed branches
- Use useMessageContext for isSubmitting/isLatestMessage awareness so
the "Summarizing..." label only shows during active streaming
- Default to collapsed (matching Reasoning), user toggles to expand
- Add proper aria attributes (aria-hidden, role, aria-controls, contentId)
- Hide copy button while actively streaming
feat(summarization): default to self-summarize using agent's own provider/model
When no summarization config is provided (neither in librechat.yaml nor
on the agent), automatically enable summarization using the agent's own
provider and model. The agents package already provides default prompts,
so no prompt configuration is needed.
Also removes the dead resolveSummarizationLLMConfig in summarize.ts
(and its spec) — run.ts buildAgentContext is the single source of truth
for summarization config resolution. Removes the duplicate
RuntimeSummarizationConfig local type in favor of the canonical
SummarizationConfig from data-provider.
chore: schema and type cleanup for summarization
- Add trigger field to summarizationAgentOverrideSchema so per-agent
trigger overrides in librechat.yaml are not silently stripped by Zod
- Remove unused SummarizationStatus type from runs.ts
- Make AppSummarizationConfig.enabled non-optional to reflect the
invariant that loadSummarizationConfig always sets it
refactor(responses): extract duplicated on_agent_log handler
refactor(run): use agents package types for summarization config
Import SummarizationConfig, ContextPruningConfig, and
OverflowRecoveryConfig from @librechat/agents and use them to
type-check the translation layer in buildAgentContext. This ensures
the config object passed to the agent graph matches what it expects.
- Use `satisfies AgentSummarizationConfig` on the config object
- Cast contextPruningConfig and overflowRecoveryConfig to agents types
- Properly narrow trigger fields from DeepPartial to required shape
feat(config): add maxToolResultChars to base endpoint schema
Add maxToolResultChars to baseEndpointSchema so it can be configured
on any endpoint in librechat.yaml. Resolved during agent initialization
using getProviderConfig's endpoint resolution: custom endpoint config
takes precedence, then the provider-specific endpoint config, then the
shared `all` config.
Passed through to the agents package ToolNode, which uses it to cap
tool result length before it enters the context window. When not
configured, the agents package computes a sensible default from
maxContextTokens.
fix(summarization): forward agent model_parameters in self-summarize default
When no explicit summarization config exists, the self-summarize
default now forwards the agent's model_parameters as the
summarization parameters. This ensures provider-specific settings
(e.g. Bedrock region, credentials, endpoint host) are available
when the agents package constructs the summarization LLM.
fix(agents): register summarization handlers by default
Change the enabled gate from === true to !== false so handlers
register when no explicit summarization config exists. This aligns
with the self-summarize default where summarization is always on
unless explicitly disabled via enabled: false.
refactor(summarization): let agents package inherit clientOptions for self-summarize
Remove model_parameters forwarding from the self-summarize default.
The agents package now reuses the agent's own clientOptions when the
summarization provider matches the agent's provider, inheriting all
provider-specific settings (region, credentials, proxy, etc.)
automatically.
refactor(summarization): use MessageContentComplex[] for summary content
Unify summary content to always use MessageContentComplex[] arrays,
matching the pattern used by on_message_delta. No more string | array
unions — content is always an array of typed blocks ({ type: 'text',
text: '...' } for text, { type: 'reasoning_content', ... } for
reasoning).
Agents package:
- SummaryContentBlock.content: MessageContentComplex[] (was string)
- tokenCount now optional (not sent on deltas)
- Removed reasoning field — reasoning is now a content block type
- streamAndCollect normalizes all chunks to content block arrays
- Delta events pass content blocks directly
LibreChat:
- SummaryContentPart.content: Agents.MessageContentComplex[]
- Updated Part.tsx, Summary.tsx, useStepHandler.ts, BaseClient.js
- Summary.tsx derives display text from content blocks via useMemo
- Aggregator uses simple array spread
refactor(summarization): enhance summary handling and text extraction
- Updated BaseClient.js to improve summary text extraction, accommodating both legacy and new content formats.
- Modified summarization logic to ensure consistent handling of summary content across different message formats.
- Adjusted test cases in summarization.e2e.spec.js to utilize the new summary text extraction method.

- Introduced a new useCopyToClipboard hook in the Summary component to encapsulate clipboard copy logic, improving code reusability and clarity.
These changes improve the overall structure and efficiency of the summarization handling and logging processes.
refactor(summarization): update summary content block documentation
- Removed outdated comment regarding the last summary content block in BaseClient.js.
- Added a new comment to clarify the purpose of the findSummaryContentBlock method, ensuring consistency in documentation.
These changes enhance code clarity and maintainability by providing accurate descriptions of the summarization logic.
refactor(summarization): update summary content structure in tests
- Modified the summarization content structure in e2e tests to use an array format for text, aligning with recent changes in summary handling.
- Updated test descriptions to clarify the behavior of context token calculations, ensuring consistency and clarity in the tests.
These changes enhance the accuracy and maintainability of the summarization tests by reflecting the updated content structure.
refactor(summarization): remove legacy E2E test setup and configuration
- Deleted the e2e-setup.js and jest.e2e.config.js files, which contained legacy configurations for E2E tests using real API keys.
- Introduced a new summarization.e2e.ts file that implements comprehensive E2E backend integration tests for the summarization process, utilizing real AI providers and tracking summaries throughout the run.

refactor(summarization): enhance test coverage for maxContextTokens behavior
- Updated run-summarization.test.ts to include a new test case ensuring that maxContextTokens does not exceed user-defined limits, even when calculated ratios suggest otherwise.
- Modified summarization.e2e.ts to replace legacy UsageMetadata type with a more appropriate type for collectedUsage, improving type safety and clarity in the test setup.
These changes improve the robustness of the summarization tests by validating context token constraints and refining type definitions.
feat(summarization): add comprehensive E2E tests for summarization process
- Introduced a new summarization.e2e.test.ts file that implements extensive end-to-end integration tests for the summarization pipeline, covering the full flow from LibreChat to agents.
- The tests utilize real AI providers and include functionality to track summaries during and between runs.
- Added necessary cleanup steps to manage Redis connections post-tests and ensure proper exit.
These changes enhance the testing framework by providing robust coverage for the summarization process, ensuring reliability and performance under real-world conditions.
fix(service): import logger from winston configuration
- Removed the import statement for logger from '@librechat/data-schemas' and replaced it with an import from '~/config/winston'.
- This change ensures that the logger is correctly sourced from the updated configuration, improving consistency in logging practices across the application.

- Removed the unused `meta` prop from the `SummaryButton` component to streamline its interface.
- Updated the token display logic to use a localized string for better internationalization support.
- Adjusted the rendering of the `meta` information to improve its visibility within the `Summary` component.
These changes enhance the clarity and usability of the Summary component while ensuring better localization practices.
feat(summarization): add maxInputTokens configuration for summarization
- Introduced a new `maxInputTokens` property in the summarization configuration schema to control the amount of conversation context sent to the summarizer, with a default value of 10000.
- Updated the `createRun` function to utilize the new `maxInputTokens` setting, allowing for more flexible summarization based on agent context.
These changes enhance the summarization capabilities by providing better control over input token limits, improving the overall summarization process.
refactor(summarization): simplify maxInputTokens logic in createRun function
- Updated the logic for the `maxInputTokens` property in the `createRun` function to directly use the agent's base context tokens when the resolved summarization configuration does not specify a value.
- This change streamlines the configuration process and enhances clarity in how input token limits are determined for summarization.
These modifications improve the maintainability of the summarization configuration by reducing complexity in the token calculation logic.
feat(summary): enhance Summary component to display meta information
- Updated the SummaryContent component to accept an optional `meta` prop, allowing for additional contextual information to be displayed above the main content.

* fix: Resolve agent provider endpoint type for file upload support
When using the agents endpoint with a custom provider (e.g., Moonshot),
the endpointType was resolving to "agents" instead of the provider's
actual type ("custom"), causing "Upload to Provider" to not appear in
the file attach menu.
Adds `resolveEndpointType` utility in data-provider that follows the
chain: endpoint (if not agents) → agent.provider → agents. Applied
consistently across AttachFileChat, DragDropContext, useDragHelpers,
and AgentPanel file components (FileContext, FileSearch, Code/Files).
* refactor: Extract useAgentFileConfig hook, restore deleted tests, fix review findings
- Extract shared provider resolution logic into useAgentFileConfig hook

- Widen useAgentFileConfig return type to EModelEndpoint | string
- Fix import order in FileContext.tsx and FileSearch.tsx
- Remove dead endpointType param from setupMocks in AttachFileMenu test
* fix: Pass resolved provider endpoint to file upload validation
AgentPanel file components (FileContext, FileSearch, Code/Files) were
hardcoding endpointOverride to "agents", causing both client-side
validation (file limits, MIME types) and server-side validation to
use the agents config instead of the provider-specific config.
Adds endpointTypeOverride to UseFileHandling params so endpoint and
endpointType can be set independently. Components now pass the
resolved provider name and type from useAgentFileConfig, so the full
fallback chain (provider → custom → agents → default) applies to
file upload validation on both client and server.
* test: Verify any custom endpoint is document-supported regardless of name
Adds parameterized tests with arbitrary endpoint names (spaces, hyphens,
colons, etc.) confirming that all custom endpoints resolve to
document-supported through resolveEndpointType, both as direct
endpoints and as agent providers.
* fix: Use || for provider fallback, test endpointOverride wiring
- Change providerValue ?? to providerValue || so empty string is
treated as "no provider" consistently with resolveEndpointType
- Add wiring tests to CodeFiles, FileContext, FileSearch verifying
endpointOverride and endpointTypeOverride are passed correctly
- Update endpointOverride JSDoc to document endpointType fallback

* fix: subdirectory redirects
* fix: use path-segment boundary check when stripping BASE_URL prefix
A bare `startsWith(BASE_URL)` matches on character prefix, not path
segments. With BASE_URL="/chat", a path like "/chatroom/c/abc" would
incorrectly strip to "room/c/abc" (no leading slash). Guard with an
exact-match-or-slash check: `p === BASE_URL || p.startsWith(BASE_URL + '/')`.
Also removes the dead `BASE_URL !== '/'` guard — module init already
converts '/' to ''.
* test: add path-segment boundary tests and clarify subdirectory coverage
- Add /chatroom, /chatbot, /app/chatroom regression tests to verify
BASE_URL stripping only matches on segment boundaries
- Clarify useAuthRedirect subdirectory test documents React Router
basename behavior (BASE_URL stripping tested in api-endpoints-subdir)
- Use `delete proc.browser` instead of undefined assignment for cleanup
- Add rationale to eslint-disable comment for isolateModules require
* fix: use relative path and correct instructions in subdirectory test script
- Replace hardcoded /home/danny/LibreChat/.env with repo-root-relative
path so the script works from any checkout location
- Update instructions to use production build (npm run build && npm run
backend) since nginx proxies to :3080 which only serves the SPA after
a full build, not during frontend:dev on :3090
* fix: skip pointless redirect_to=/ for root path and fix jsdom 26+ compat
buildLoginRedirectUrl now returns plain /login when the resolved path
is root — redirect_to=/ adds no value since / immediately redirects
to /c/new after login anyway.
Also rewrites api-endpoints.spec.ts to use window.history.replaceState
instead of Object.defineProperty(window, 'location', ...) which jsdom
26+ no longer allows.
* test: fix request-interceptor.spec.ts for jsdom 26+ compatibility
Switch from jsdom to happy-dom environment which allows
Object.defineProperty on window.location. jsdom 26+ made
location non-configurable, breaking all 8 tests in this file.
* chore: update browser property handling in api-endpoints-subdir test
Changed the handling of the `proc.browser` property from deletion to setting it to false, ensuring compatibility with the current testing environment.
* chore: update backend restart instructions in test subdirectory setup script
Changed the instruction for restarting the backend from "npm run backend:dev" to "npm run backend" to reflect the correct command for the current setup.
* refactor: ensure proper cleanup in loadModuleWithBase function
Wrapped the module loading logic in a try-finally block to guarantee that the `proc.browser` property is reset to false and the base element is removed, improving reliability in the testing environment.
* refactor: improve browser property handling in loadModuleWithBase function
Revised the management of the `proc.browser` property to store the original value before modification, ensuring it is restored correctly after module loading. This enhances the reliability of the testing environment.
* chore: npm audit

- Changed the text for the "No Auth" message to "None (Auto-detect)" in the English translation file, enhancing clarity for users regarding authentication status.
* ♻️ refactor: Centralize `buildLoginRedirectUrl` in data-provider
Move `buildLoginRedirectUrl` from `client/src/utils/redirect.ts` into
`packages/data-provider/src/api-endpoints.ts` so the axios 401
interceptor (and any other data-provider consumer) can use the canonical
implementation with the LOGIN_PATH_RE guard and BASE_URL awareness.
The client module now re-exports from `librechat-data-provider`, keeping
all existing imports working unchanged.
* 🔒 fix: Shared link 401 interceptor bypass and redirect loop (#12033)
Fixes three issues in the axios 401 response interceptor that prevented
private shared links (ALLOW_SHARED_LINKS_PUBLIC=false) from working:
1. `window.location.href.includes('share/')` matched the full URL
(including query params and hash), causing false positives. Changed
to `window.location.pathname.startsWith('/share/')`.
2. When token refresh returned no token on a share page, the
interceptor logged and fell through without redirecting, causing an
infinite retry loop via React Query. Now redirects to login using
`buildLoginRedirectUrl()` which preserves the share URL for
post-login navigation.
3. `processQueue` was never called in the no-token branch, leaving
queued requests with dangling promise callbacks. Added
`processQueue(error, null)` before the redirect.
* ✅ test: Comprehensive 401 interceptor tests for shared link auth flow
Rewrite interceptor test suite to cover all shared link auth scenarios:
- Unauthenticated user on share page with failed refresh → redirect
- Authenticated user on share page with failed refresh → redirect
- share/ in query params does NOT bypass the auth header guard
- Login path guard: redirect to plain /login (no redirect_to loop)
- Refresh success: assert exact call count (toBe(3) vs toBeGreaterThan)
Test reliability improvements:
- window.location teardown moved to afterEach (no state leak on failure)
- expect.assertions(N) on all tests (catch silent false passes)
- Shared setWindowLocation helper for consistent location mocking
* ♻️ refactor: Import `buildLoginRedirectUrl` directly from data-provider
Update `AuthContext.tsx` and `useAuthRedirect.ts` to import
`buildLoginRedirectUrl` from `librechat-data-provider` instead of
re-exporting through `~/utils/redirect.ts`.
Convert `redirect.ts` to ESM-style inline exports and remove the
re-export of `buildLoginRedirectUrl`.
* ✅ test: Move `buildLoginRedirectUrl` tests to data-provider
Tests for `buildLoginRedirectUrl` now live alongside the implementation
in `packages/data-provider/specs/api-endpoints.spec.ts`.
Removed the duplicate describe block from the client redirect test file
since it no longer owns that function.
* 🔗 fix: Preserve URL query params during silent token refresh
The silent token refresh on hard navigation was redirecting to '/c/new'
without query params, wiping the URL before ChatRoute could read them.
Now preserves the current URL (pathname + search) as the redirect
fallback, with isSafeRedirect validation.
* 🧭 fix: Apply URL query params in ChatRoute initialization
ChatRoute now reads URL search params (endpoint, model, agent_id, etc.)
and merges them into the preset passed to newConversation(), so the
first conversation init already includes the URL param settings. This
eliminates the race where useQueryParams fired too late.
- Export processValidSettings from useQueryParams for reuse
- Add getNewConvoPreset helper in ChatRoute (used in both NEW_CONVO branches)
- Query params take precedence over model spec defaults
- useQueryParams now waits for endpointsConfig before processing
- Skip redundant newQueryConvo when settings are already applied
- Clean all URL params via setSearchParams after processing
* ✅ test: Update useQueryParams tests for new URL cleanup behavior
- Assert setSearchParams called instead of window.history.replaceState
- Mock endpoints config in deferred submission and timeout tests
* ♻️ refactor: Move processValidSettings to ~/utils and address review findings
- Move processValidSettings/parseQueryValue to createChatSearchParams.ts
(pure utility, not hook-specific)
- Fix processSubmission: use setSearchParams instead of replaceState,
move URL cleanup outside data.text guard
- Narrow endpointsConfig guard: only block settings application, not
prompt-only flows
- Convert areSettingsApplied to stable useCallback ([] deps) with
conversationRef to avoid interval churn on conversation updates
- Replace console.log with logger.log in production paths
- Restore explanatory comment on pendingSubmitRef guard
- Use for...of in processValidSettings (CLAUDE.md preference)
- Remove unused imports from useQueryParams
* 🔧 fix: Add areSettingsApplied to effect deps and fix test mocks
- Restore areSettingsApplied in main effect deps (stable identity with
[] deps, safe to include — satisfies exhaustive-deps lint rule)
- Fix all test getQueryData mocks to properly distinguish between
startupConfig and endpoints keys
- Assert setSearchParams call arguments (URLSearchParams + replace:true)
* ✅ test: Assert empty URLSearchParams in setSearchParams calls
Tighten setSearchParams assertions to verify the params are empty
(toString() === ''), not just that a URLSearchParams instance was passed.
* 🔧 test: Update AuthContext tests to navigate to current URL for redirects
- Modified test cases to assert navigation to the current URL instead of a hardcoded '/c/new' when no stored redirect exists or when falling back from unsafe stored redirects.
- Enhanced test setup to define window.location for accurate simulation of redirect behavior.
* chore: Update import path for StartupLayout in tests
* 🔒 fix: Enhance AuthContext to handle stored redirects during user authentication
- Added SESSION_KEY import and logic to retrieve and clear stored redirect URLs from sessionStorage.
- Updated user context state to include redirect URL, defaulting to '/c/new' if none is found.
* 🧪 test: Add tests for silentRefresh post-login redirect handling in AuthContext
- Introduced new test suite to validate navigation behavior after successful token refresh.
- Implemented tests for stored sessionStorage redirects, default navigation, and prevention of unsafe redirects.
- Enhanced logout error handling tests to ensure proper state clearing without external redirects.
* 🔒 fix: Update AuthContext to handle unsafe stored redirects during authentication
- Removed conditional check for stored redirect in sessionStorage, ensuring it is always cleared.
- Enhanced logic to validate stored redirects, defaulting to '/c/new' for unsafe URLs.
- Updated tests to verify navigation behavior for both safe and unsafe redirects after token refresh.
* fix: key checkmark by endpoint , not just model name
* fix: model spec endpoint collision for checkmark indicators
* chore: fix formatting
* refactor: move isSelected into EndpointModelItem, fix SearchResults, add tests
Address PR review feedback:
- Move isSelected computation from renderEndpointModels into EndpointModelItem
via useModelSelectorContext, eliminating fragile positional params
- Add !selectedSpec guard to SearchResults.tsx for both model and endpoint checks
- Add unit tests for EndpointModelItem selection logic
* test: update EndpointModelItem tests and add SearchResults tests
- Update EndpointModelItem tests to replace null modelSpec with an empty string for consistency in rendering logic.
- Introduce new SearchResults tests to validate selection behavior based on endpoint and model matching, including scenarios with and without active specs.

* fix: complete OIDC logout implementation
The OIDC logout feature added in #5626 was incomplete:
1. Backend: Missing id_token_hint/client_id parameters required by the
RP-Initiated Logout spec. Keycloak 18+ rejects logout without these.
2. Frontend: The logout redirect URL was passed through isSafeRedirect()
which rejects all absolute URLs. The redirect was silently dropped.
Backend: Add id_token_hint (preferred) or client_id (fallback) to the
logout URL for OIDC spec compliance.
Frontend: Use window.location.replace() for logout redirects from the
backend, bypassing isSafeRedirect() which was designed for user-input
validation.
Fixes#5506
* fix: accept undefined in setTokenHeader to properly clear Authorization header
When token is undefined, delete the Authorization header instead of
setting it to "Bearer undefined". Removes the @ts-ignore workaround
in AuthContext.
* fix: skip axios 401 refresh when Authorization header is cleared
When the Authorization header has been removed (e.g. during logout),
the response interceptor now skips the token refresh flow. This
prevents a successful refresh from canceling an in-progress OIDC
external redirect via window.location.replace().
* fix: guard against undefined OPENID_CLIENT_ID in logout URL
Prevent literal "client_id=undefined" in the OIDC end-session URL
when OPENID_CLIENT_ID is not set. Log a warning when neither
id_token_hint nor client_id is available.
* fix: prevent race condition canceling OIDC logout redirect
The logout mutation wrapper's cleanup (clearStates, removeQueries)
triggers re-renders and 401s on in-flight requests. The axios
interceptor would refresh the token successfully, firing
dispatchTokenUpdatedEvent which cancels the window.location.replace()
navigation to the IdP's end_session_endpoint.
Fix:
- Clear Authorization header synchronously before redirect so the
axios interceptor skips refresh for post-logout 401s
- Add isExternalRedirectRef to suppress silentRefresh and useEffect
side effects during the redirect
- Add JSDoc explaining why isSafeRedirect is bypassed
* test: add LogoutController and AuthContext logout test coverage
LogoutController.spec.js (13 tests):
- id_token_hint from session and cookie fallback
- client_id fallback, including undefined OPENID_CLIENT_ID guard
- Disabled endpoint, missing issuer, non-OpenID user
- post_logout_redirect_uri (custom and default)
- Missing OpenID config and end_session_endpoint
- Error handling and cookie clearing
AuthContext.spec.tsx (3 tests):
- OIDC redirect calls window.location.replace + setTokenHeader
- Non-redirect logout path
- Logout error handling
* test: add coverage for setTokenHeader, axios interceptor guard, and silentRefresh suppression
headers-helpers.spec.ts (3 tests):
- Sets Authorization header with Bearer token
- Deletes Authorization header when called with undefined
- No-op when clearing an already absent header
request-interceptor.spec.ts (2 tests):
- Skips refresh when Authorization header is cleared (the race fix)
- Attempts refresh when Authorization header is present
AuthContext.spec.tsx (1 new test):
- Verifies silentRefresh is not triggered after OIDC redirect
* test: enhance request-interceptor tests with adapter restoration and refresh verification
- Store the original axios adapter before tests and restore it after all tests to prevent side effects.
- Add verification for the refresh endpoint call in the interceptor tests to ensure correct behavior during token refresh attempts.
* test: enhance AuthContext tests with live rendering and improved logout error handling
- Introduced a new `renderProviderLive` function to facilitate testing with silentRefresh.
- Updated tests to use the live rendering function, ensuring accurate simulation of authentication behavior.
- Enhanced logout error handling test to verify that auth state is cleared without external redirects.
* test: update LogoutController tests for OpenID config error handling
- Renamed test suite to clarify that it handles cases when OpenID config is not available.
- Modified test to check for error thrown by getOpenIdConfig instead of returning null, ensuring proper logging of the error message.
* refactor: improve OpenID config error handling in LogoutController
- Simplified error handling for OpenID configuration retrieval by using a try-catch block.
- Updated logging to provide clearer messages when the OpenID config is unavailable.
- Ensured that the end session endpoint is only accessed if the OpenID config is successfully retrieved.

- Set Conversations list role as "rowgroup", which better describes
what is actually going on than "row".
- Increased contrast on placeholder text in ChatForm.
The drag & drop background was practically translucent, which made
it hard to see the rest of the overlay (especially on light mode).
Now, we no longer make the background translucent, so you can see
the overlay clearly.
When content is hidden (or in the background of the active form),
users shouldn't be allowed to access that content. However, right now,
you can use a keyboard (or screen reader) to move over to this content.
By adding `inert`, we make this content no longer accessible when hidden.
I've done this in two places:
- The sidebar is now inert when it's closed.
- When the sidebar is open & the window is small, the content area is
inert (since it's mostly obscured by the sidebar).
* fix: title sanitization with max length truncation and update ShareView for better text display
- Added functionality to `sanitizeTitle` to truncate titles exceeding 200 characters with an ellipsis, ensuring consistent title length.
- Updated `ShareView` component to apply a line clamp on the title, improving text display and preventing overflow in the UI.
* refactor: Update layout and styling in MessagesView and ShareView components
- Removed unnecessary padding in MessagesView to streamline the layout.
- Increased bottom padding in the message container for better spacing.
- Enhanced ShareView footer positioning and styling for improved visibility.
- Adjusted section and div classes in ShareView for better responsiveness and visual consistency.
* fix: Correct title fallback and enhance sanitization logic in sanitizeTitle
- Updated the fallback title in sanitizeTitle to use DEFAULT_TITLE_FALLBACK instead of a hardcoded string.
- Improved title truncation logic to ensure proper handling of maximum length and whitespace, including edge cases for emoji and whitespace-only titles.
- Added tests to validate the new sanitization behavior, ensuring consistent and expected results across various input scenarios.
AccountSettings was using Select, but it makes more sense (for a11y)
to use Menu. The Select has the wrong role & behavior for the purpose
of AccountSettings; the "listbox" role it uses is for selecting
values in a form.
Menu matches the actual content better for screen readers; the
"menu" role is more appropriate for selecting one of a number of links.

- Enhanced logic to validate `reasoning_effort` against the defined configuration values before assigning to `reasoning_config`.
- Improved code clarity with additional comments and refactored conditions for better readability.
* fix: Use correct endpoint for file validation in agent panel uploads
Agent panel file uploads (FileSearch, FileContext, Code/Files) were validating against the active conversation's endpoint config instead of the agents endpoint config. This caused incorrect file size limits when the active chat used a different endpoint.
Add endpointOverride option to useFileHandling so callers can specify the correct endpoint for validation independent of the active conversation.
* fix: Use agents endpoint config for agent panel file upload validation
Agent panel file uploads (FileSearch, FileContext, Code/Files) validated
against the active conversation's endpoint config instead of the agents
endpoint config. This caused wrong file size limits when the active chat
used a different endpoint.
Adds endpointOverride to useFileHandling so callers can specify the
correct endpoint for both validation and upload routing, independent of
the active conversation.
* test: Add unit tests for useFileHandling hook to validate endpoint overrides
Introduced comprehensive tests for the useFileHandling hook, ensuring correct behavior when using endpoint overrides for file validation and upload routing. The tests cover various scenarios, including fallback to conversation endpoints and proper handling of agent-specific configurations, enhancing the reliability of file handling in the application.

* 🔧 fix: Update AuthContextProvider to prevent infinite re-fire of useEffect
- Modified the dependency array of the useEffect hook in AuthContextProvider to an empty array, preventing unnecessary re-executions and potential infinite loops. Added an ESLint comment to clarify the decision regarding stable dependencies at mount.
* chore: import order
* fix: Prevent recursive login redirect loop
buildLoginRedirectUrl() would blindly encode the current URL into a
redirect_to param even when already on /login, causing infinite nesting
(/login?redirect_to=%2Flogin%3Fredirect_to%3D...). Guard at source so
it returns plain /login when pathname starts with /login.
Also validates redirect_to in the login error handler with isSafeRedirect
to close an open-redirect vector, and removes a redundant /login guard
from useAuthRedirect now handled by the centralized check.
* 🔀 fix: Handle basename-prefixed login paths and remove double URL decoding
buildLoginRedirectUrl now uses isLoginPath() which matches /login,
/librechat/login, and /login/2fa — covering subdirectory deployments
where window.location.pathname includes the basename prefix.
Remove redundant decodeURIComponent calls on URLSearchParams.get()
results (which already returns decoded values) in getPostLoginRedirect,
Login.tsx, and AuthContext login error handler. The extra decode could
throw URIError on inputs containing literal percent signs.
* 🔀 fix: Tighten login path matching and add onError redirect tests
Replace overbroad `endsWith('/login')` with a single regex
`/(^|\/)login(\/|$)/` that matches `/login` only as a full path
segment. Unifies `isSafeRedirect` and `buildLoginRedirectUrl` to use
the same `LOGIN_PATH_RE` constant — no more divergent definitions.
Add tests for the AuthContext onError redirect_to preservation logic
(valid path preserved, open-redirect blocked, /login loop blocked),
and a false-positive guard proving `/c/loginhistory` is not matched.
Update JSDoc on `buildLoginRedirectUrl` to document the plain `/login`
early-return, and add explanatory comment in AuthContext `onError`
for why `buildLoginRedirectUrl()` cannot be used there.
* test: Add unit tests for AuthContextProvider login error handling
Introduced a new test suite for AuthContextProvider to validate the handling of login errors and the preservation of redirect parameters. The tests cover various scenarios including valid redirect preservation, open-redirect prevention, and recursive redirect prevention. This enhances the robustness of the authentication flow and ensures proper navigation behavior during login failures.

* fix(a11y): hide collapsed thinking content from screen readers and link toggle to controlled region
The thinking/reasoning toggle button visually collapsed content using a CSS
grid animation (gridTemplateRows: 0fr + overflow-hidden), but the content
remained in the DOM and fully accessible to screen readers, cluttering the
reading flow for assistive technology users.
- Add aria-hidden={!isExpanded} to the collapsible content region in both
the legacy Thinking component and the modern Reasoning component, so
screen readers skip collapsed thoughts entirely
- Add role="region" and a unique id (via useId) to each collapsible content
div, giving it a semantic landmark for assistive technology
- Add contentId prop to the shared ThinkingButton and wire it to
aria-controls on the toggle button, establishing an explicit relationship
between the button and the region it expands/collapses
- aria-expanded was already present on the button; combined with
aria-controls, screen readers can now fully convey the toggle state and
its target
* fix(a11y): add aria-label to collapsible content regions in Thinking and Reasoning components
Enhanced accessibility by adding aria-label attributes to the collapsible content regions in both the Thinking and Reasoning components. This change ensures that screen readers can provide better context for users navigating through the content.

* feat: add aws bedrock upload to provider support
* chore: address copilot comments
* feat: add shared Bedrock document format types and MIME mapping
Bedrock Converse API accepts 9 document formats beyond PDF. Add
BedrockDocumentFormat union type, MIME-to-format mapping, and helpers
in data-provider so both client and backend can reference them.
* refactor: generalize Bedrock PDF validation to support all document types
Rename validateBedrockPdf to validateBedrockDocument with MIME-aware
logic: 4.5MB hard limit applies to all types, PDF header check only
runs for application/pdf. Adds test coverage for non-PDF documents.
* feat: support all Bedrock document formats in encoding pipeline
Widen file type gates to accept csv, doc, docx, xls, xlsx, html, txt,
md for Bedrock. Uses shared MIME-to-format map instead of hardcoded
'pdf'. Other providers' PDF-only paths remain unchanged.

filters for all 9 supported formats. Update drag-and-drop validation
to use isBedrockDocumentType helper.
* fix: route Bedrock document types through provider pipeline
* fix: route to new conversation when conversation not found
* Addressed PR feedback
* fix: Robust 404 conversation redirect handling
- Extract `isNotFoundError` utility to `utils/errors.ts` so axios stays
contained in one place rather than leaking into route/query layers

the redirect actually fires when the 404 response arrives after other
deps have already settled (was the root cause of the blank screen)
- Show a warning toast so users understand why they were redirected
- Add `com_ui_conversation_not_found` i18n key
* fix: Enhance error handling in getResponseStatus function
- Update the getResponseStatus function to ensure it correctly returns the status from error objects only if the status is a number. This improves robustness in error handling by preventing potential type issues.

* chore: Update .env.example to include CONTINUE_ON_UNCAUGHT_EXCEPTION variable
Added documentation for the CONTINUE_ON_UNCAUGHT_EXCEPTION environment variable, which allows the app to continue running after encountering uncaught exceptions. This change is not recommended for production environments unless necessary.
* 🔧 refactor: Simplify MCP selection logic in useMCPSelect hook
- Removed redundant useEffect for setting ephemeral agent when MCP values change.
- Integrated ephemeral agent update directly into the MCP value change handler, improving code clarity and reducing unnecessary re-renders.
- Updated dependencies in the effect hook to ensure proper state management.
Why Effect 2 Was Added (PR #9528)
PR #9528 was a refactor that migrated MCP state from useLocalStorage hooks to Jotai atomWithStorage. Before that PR, useLocalStorage
handled bidirectional sync between localStorage and Recoil in one abstraction. After the migration, the two useEffect hooks were
introduced to bridge Jotai ↔ Recoil:
- Effect 1 (Recoil → Jotai): When ephemeralAgent.mcp changes externally, update the Jotai atom (which drives the UI dropdown)
- Effect 2 (Jotai → Recoil): When mcpValues changes, push it back to ephemeralAgent.mcp (which is read at submission time)
Effect 2 was needed because in that PR's design, setMCPValues only wrote to Jotai — it never touched Recoil. Effect 2 was the bridge to
propagate user selections into the ephemeral agent.
Why Removing It Is Correct
All user-initiated MCP changes go through setMCPValues. The callers are in useMCPServerManager: toggleServerSelection,
batchToggleServers, OAuth success callbacks, and access revocation. Our change puts the Recoil write directly in that callback, so all
these paths are covered.
All external changes go through Recoil, handled by Effect 1 (kept). Model spec application (applyModelSpecEphemeralAgent), agent
template application after submission, and BadgeRowContext initialization all write directly to ephemeralAgentByConvoId. Effect 1
watches ephemeralAgent?.mcp and syncs those into the Jotai atom for the UI.
There is no code path where mcpValues changes without going through setMCPValues or Effect 1. The only other source is
atomWithStorage's getOnInit reading from localStorage on mount — that's just restoring persisted state and is harmless (overwritten by
Effect 1 if the ephemeral agent has values).
Additional Benefits
- Eliminates the race condition. Effect 2 fired on mount with Jotai's stale default ([]), overwriting ephemeralAgent.mcp that had been
set by a model spec. Our change prevents that because the imperative sync only fires on explicit user action.
- Eliminates infinite loop risk. The old bidirectional two-effect approach relied on isEqual/JSON.stringify checks to break cycles. The
new unidirectional-reactive (Effect 1) + imperative (setMCPValues) approach has no such risk.
- Effect 1's enhancements are preserved. The mcp_clear sentinel handling and configuredServers filtering (both added after PR #9528)
continue to work correctly.
* ✨ feat: Add artifacts support to model specifications and ephemeral agents
- Introduced `artifacts` property in the model specification and ephemeral agent types, allowing for string or boolean values.
- Updated `applyModelSpecEphemeralAgent` to handle artifacts, defaulting to 'default' if true or an empty string if not specified.
- Enhanced localStorage handling to store artifacts alongside other agent properties, improving state management for ephemeral agents.
* 🔧 refactor: Update BadgeRowContext to improve localStorage handling
- Modified the logic to only apply values from localStorage that were actually stored, preventing unnecessary overrides of the ephemeral agent.
- Simplified the setting of ephemeral agent values by directly using initialValues, enhancing code clarity and maintainability.
* 🔧 refactor: Enhance ephemeral agent handling in BadgeRowContext and model spec application
- Updated BadgeRowContext to apply localStorage values only for tools not already set in ephemeralAgent, improving state management.
- Modified useApplyModelSpecEffects to reset the ephemeral agent when no spec is provided but specs are configured, ensuring localStorage defaults are applied correctly.
- Streamlined the logic for applying model spec properties, enhancing clarity and maintainability.
* refactor: Isolate spec and non-spec tool/MCP state with environment-keyed storage
Spec tool state (badges, MCP) and non-spec user preferences previously shared
conversation-keyed localStorage, causing cross-pollination when switching between
spec and non-spec models. This introduces environment-keyed storage so each
context maintains independent persisted state.
Key changes:
- Spec active: no localStorage persistence — admin config always applied fresh
- Non-spec (with specs configured): tool/MCP state persisted to __defaults__ key
- No specs configured: zero behavior change (conversation-keyed storage)
- Per-conversation isolation preserved for existing conversations
- Dual-write on user interaction updates both conversation and environment keys
- Remove mcp_clear sentinel in favor of null ephemeral agent reset
* refactor: Enhance ephemeral agent initialization and MCP handling in BadgeRowContext and useMCPSelect
- Updated BadgeRowContext to clarify the handling of localStorage values for ephemeral agents, ensuring proper initialization based on conversation state.
- Improved useMCPSelect tests to accurately reflect behavior when setting empty MCP values, ensuring the visual selection clears as expected.
- Introduced environment-keyed storage logic to maintain independent state for spec and non-spec contexts, enhancing user experience during context switching.
* test: Add comprehensive tests for useToolToggle and applyModelSpecEphemeralAgent hooks
- Introduced unit tests for the useToolToggle hook, covering dual-write behavior in non-spec mode and per-conversation isolation.
- Added tests for applyModelSpecEphemeralAgent, ensuring correct application of model specifications and user overrides from localStorage.

- Introduced `getDefaultParamsEndpoint` function to streamline the retrieval of `defaultParamsEndpoint` across various hooks and middleware.
- Updated multiple files to utilize the new function, enhancing code consistency and maintainability.
- Removed redundant logic for fetching `defaultParamsEndpoint`, simplifying the codebase.
- Introduced a new `EndpointMenuContent` component to lazily render endpoint submenu content, improving performance by deferring expensive model-list rendering until the submenu is mounted.
- Refactored `EndpointItem` to utilize the new component, simplifying the code and enhancing readability.
- Removed redundant filtering logic and model specifications handling from `EndpointItem`, centralizing it within `EndpointMenuContent` for better maintainability.
