⚗️ feat: Agent Context Compaction/Summarization (#12287)
* chore: imports/types

Add summarization config and package-level summarize handler contracts

Register summarize handlers across server controller paths

Port cursor dual-read/dual-write summary support and UI status handling

Selectively merge cursor branch files for BaseClient summary content
block detection (last-summary-wins), dual-write persistence, summary
block unit tests, and on_summarize_status SSE event handling with
started/completed/failed branches.

Co-authored-by: Cursor <cursoragent@cursor.com>

refactor: type safety

feat: add localization for summarization status messages

refactor: optimize summary block detection in BaseClient

Updated the logic for identifying existing summary content blocks to use a reverse loop for improved efficiency. Added a new test case to ensure the last summary content block is updated correctly when multiple summary blocks exist.

chore: add runName to chainOptions in AgentClient

refactor: streamline summarization configuration and handler integration

Removed the deprecated summarizeNotConfigured function and replaced it with a more flexible createSummarizeFn. Updated the summarization handler setup across various controllers to utilize the new function, enhancing error handling and configuration resolution. Improved overall code clarity and maintainability by consolidating summarization logic.

feat(summarization): add staged chunk-and-merge fallback

feat(usage): track summarization usage separately from messages

feat(summarization): resolve prompt from config in runtime

fix(endpoints): use @librechat/api provider config loader

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.

refactor(summarization): include initial summary in formatAgentMessages output

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. Implemented reserveTokensRatio in the createRun function to allow configurable context token management. Updated related tests to validate these changes and ensure proper functionality.

feat(summarization): add minReserveTokens, context pruning, and overflow recovery configurations

Introduced new configuration options for summarization, including minReserveTokens, context pruning settings, and overflow recovery parameters. Updated the createRun function to accommodate these new options and added a comprehensive test suite to validate their functionality and integration within the summarization process.

feat(summarization): add updatePrompt and reserveTokensRatio to summarization configuration

Introduced an updatePrompt field for updating existing summaries with new messages, enhancing the flexibility of the summarization process. Additionally, added reserveTokensRatio to the configuration schema, allowing for improved management of token allocation during summarization. Updated related tests to validate these new features.

feat(logging): add on_agent_log event handler for structured logging

Implemented an on_agent_log event handler in both the agents' callbacks and responses to facilitate structured logging of agent activities. 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.
- Refined SSE useStepHandler to initialize summary content as an array.

- 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.

These changes streamline the testing framework by consolidating E2E tests into a single, more robust file while removing outdated configurations.

refactor(summarization): enhance E2E tests and error handling

- Added a cleanup step to force exit after all tests to manage Redis connections.
- Updated the summarization model to 'claude-haiku-4-5-20251001' for consistency across tests.
- Improved error handling in the processStream function to capture and return processing errors.
- Enhanced logging for cross-run tests and tight context scenarios to provide better insights into test execution.

These changes improve the reliability and clarity of the E2E tests for the summarization process.

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.

refactor(summary): simplify Summary component and enhance token display

- 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.
- Adjusted the rendering logic in the Summary component to utilize the new `meta` prop, improving the visibility of supplementary details.

These changes enhance the user experience by providing more context within the Summary component, making it clearer and more informative.

refactor(summarization): standardize reserveRatio configuration in summarization logic

- Replaced instances of `reserveTokensRatio` with `reserveRatio` in the `createRun` function and related tests to unify the terminology across the codebase.
- Updated the summarization configuration schema to reflect this change, ensuring consistency in how the reserve ratio is defined and utilized.
- Removed the per-agent override logic for summarization configuration, simplifying the overall structure and enhancing clarity.

These modifications improve the maintainability and readability of the summarization logic by standardizing the configuration parameters.

* fix: circular dependency of `~/models`

* chore: update logging scope in agent log handlers

Changed log scope from `[agentus:${data.scope}]` to `[agents:${data.scope}]` in both the callbacks and responses controllers to ensure consistent logging format across the application.

* feat: calibration ratio

* refactor(tests): update summarizationConfig tests to reflect changes in enabled property

Modified tests to check for the new `summarizationEnabled` property instead of the deprecated `enabled` field in the summarization configuration. This change ensures that the tests accurately validate the current configuration structure and behavior of the agents.

* feat(tests): add markSummarizationUsage mock for improved test coverage

Introduced a mock for the markSummarizationUsage function in the responses unit tests to enhance the testing of summarization usage tracking. This addition supports better validation of summarization-related functionalities and ensures comprehensive test coverage for the agents' response handling.

* refactor(tests): simplify event handler setup in createResponse tests

Removed redundant mock implementations for event handlers in the createResponse unit tests, streamlining the setup process. This change enhances test clarity and maintainability while ensuring that the tests continue to validate the correct behavior of usage tracking during on_chat_model_end events.

* refactor(agents): move calibration ratio capture to finally block

Reorganized the logic for capturing the calibration ratio in the AgentClient class to ensure it is executed in the finally block. This change guarantees that the ratio is captured even if the run is aborted, enhancing the reliability of the response message persistence. Removed redundant code and improved clarity in the handling of context metadata.

* refactor(agents): streamline bulk write logic in recordCollectedUsage function

Removed redundant bulk write operations and consolidated document handling in the recordCollectedUsage function. The logic now combines all documents into a single bulk write operation, improving efficiency and reducing error handling complexity. Updated logging to provide consistent error messages for bulk write failures.

* refactor(agents): enhance summarization configuration resolution in createRun function

Streamlined the summarization configuration logic by introducing a base configuration and allowing for overrides from agent-specific settings. This change improves clarity and maintainability, ensuring that the summarization configuration is consistently applied while retaining flexibility for customization. Updated the handling of summarization parameters to ensure proper integration with the agent's model and provider settings.

* refactor(agents): remove unused tokenCountMap and streamline calibration ratio handling

Eliminated the unused tokenCountMap variable from the AgentClient class to enhance code clarity. Additionally, streamlined the logic for capturing the calibration ratio by using optional chaining and a fallback value, ensuring that context metadata is consistently defined. This change improves maintainability and reduces potential confusion in the codebase.

* refactor(agents): extract agent log handler for improved clarity and reusability

Refactored the agent log handling logic by extracting it into a dedicated function, `agentLogHandler`, enhancing code clarity and reusability across different modules. Updated the event handlers in both the OpenAI and responses controllers to utilize the new handler, ensuring consistent logging behavior throughout the application.

* test: add summarization event tests for useStepHandler

Implemented a series of tests for the summarization events in the useStepHandler hook. The tests cover scenarios for ON_SUMMARIZE_START, ON_SUMMARIZE_DELTA, and ON_SUMMARIZE_COMPLETE events, ensuring proper handling of summarization logic, including message accumulation and finalization. This addition enhances test coverage and validates the correct behavior of the summarization process within the application.

* refactor(config): update summarizationTriggerSchema to use enum for type validation

Changed the type of the `type` field in the summarizationTriggerSchema from a string to an enum with a single value 'token_count'. This modification enhances type safety and ensures that only valid types are accepted in the configuration, improving overall clarity and maintainability of the schema.

* test(usage): add bulk write tests for message and summarization usage

Implemented tests for the bulk write functionality in the recordCollectedUsage function, covering scenarios for combined message and summarization usage, summarization-only usage, and message-only usage. These tests ensure correct document handling and token rollup calculations, enhancing test coverage and validating the behavior of the usage tracking logic.

* refactor(Chat): enhance clipboard copy functionality and type definitions in Summary component

Updated the Summary component to improve the clipboard copy functionality by handling clipboard permission errors. Refactored type definitions for SummaryProps to use a more specific type, enhancing type safety. Adjusted the SummaryButton and FloatingSummaryBar components to accept isCopied and onCopy props, promoting better separation of concerns and reusability.

* chore(translations): remove unused "Expand Summary" key from English translations

Deleted the "Expand Summary" key from the English translation file to streamline the localization resources and improve clarity in the user interface. This change helps maintain an organized and efficient translation structure.

* refactor: adjust token counting for Claude model to account for API discrepancies

Implemented a correction factor for token counting when using the Claude model, addressing discrepancies between Anthropic's API and local tokenizer results. This change ensures accurate token counts by applying a scaling factor, improving the reliability of token-related functionalities.

* refactor(agents): implement token count adjustment for Claude model messages

Added a method to adjust token counts for messages processed by the Claude model, applying a correction factor to align with API expectations. This enhancement improves the accuracy of token counting, ensuring reliable functionality when interacting with the Claude model.

* refactor(agents): token counting for media content in messages

Introduced a new method to estimate token costs for image and document blocks in messages, improving the accuracy of token counting. This enhancement ensures that media content is properly accounted for, particularly for the Claude model, by integrating additional token estimation logic for various content types. Updated the token counting function to utilize this new method, enhancing overall reliability and functionality.

* chore: fix missing import

* fix(agents): clamp baseContextTokens and document reserve ratio change

Prevent negative baseContextTokens when maxOutputTokens exceeds the
context window (misconfigured models). Document the 10%→5% default
reserve ratio reduction introduced alongside summarization.

* fix(agents): include media tokens in hydrated token counts

Add estimateMediaTokensForMessage to createTokenCounter so the hydration
path (used by hydrateMissingIndexTokenCounts) matches the precomputed
path in AgentClient.getTokenCountForMessage. Without this, messages
containing images or documents were systematically undercounted during
hydration, risking context window overflow.

Add 34 unit tests covering all block-type branches of
estimateMediaTokensForMessage.

* fix(agents): include summarization output tokens in usage return value

The returned output_tokens from recordCollectedUsage now reflects all
billed LLM calls (message + summarization). Previously, summarization
completions were billed but excluded from the returned metadata, causing
a discrepancy between what users were charged and what the response
message reported.

* fix(tests): replace process.exit with proper Redis cleanup in e2e test

The summarization E2E test used process.exit(0) to work around a Redis
connection opened at import time, which killed the Jest runner and
bypassed teardown. Use ioredisClient.quit() and keyvRedisClient.disconnect()
for graceful cleanup instead.

* fix(tests): update getConvo imports in OpenAI and response tests

Refactor test files to import getConvo from the main models module instead of the Conversation submodule. This change ensures consistency across tests and simplifies the import structure, enhancing maintainability.

* fix(clients): improve summary text validation in BaseClient

Refactor the summary extraction logic to ensure that only non-empty summary texts are considered valid. This change enhances the robustness of the message processing by utilizing a dedicated method for summary text retrieval, improving overall reliability.

* fix(config): replace z.any() with explicit union in summarization schema

Model parameters (temperature, top_p, etc.) are constrained to
primitive types rather than the policy-violating z.any().

* refactor(agents): deduplicate CLAUDE_TOKEN_CORRECTION constant

Export from the TS source in packages/api and import in the JS client,
eliminating the static class property that could drift out of sync.

* refactor(agents): eliminate duplicate selfProvider in buildAgentContext

selfProvider and provider were derived from the same expression with
different type casts. Consolidated to a single provider variable.

* refactor(agents): extract shared SSE handlers and restrict log levels

- buildSummarizationHandlers() factory replaces triplicated handler
  blocks across responses.js and openai.js
- agentLogHandlerObj exported from callbacks.js for consistent reuse
- agentLogHandler restricted to an allowlist of safe log levels
  (debug, info, warn, error) instead of accepting arbitrary strings

* fix(SSE): batch summarize deltas, add exhaustiveness check, conditional error announcement

- ON_SUMMARIZE_DELTA coalesces rapid-fire renders via requestAnimationFrame
  instead of calling setMessages per chunk
- Exhaustive never-check on TStepEvent catches unhandled variants at
  compile time when new StepEvents are added
- ON_SUMMARIZE_COMPLETE error announcement only fires when a summary
  part was actually present and removed

* feat(agents): persist instruction overhead in contextMeta and seed across runs

Extend contextMeta with instructionOverhead and toolCount so the
provider-observed instruction overhead is persisted on the response message
and seeded into the pruner on subsequent runs. This enables the pruner to
use a calibrated budget from the first call instead of waiting for a
provider observation, preventing the ratio collapse caused by local
tokenizer overestimating tool schema tokens.

The seeded overhead is only used when encoding and tool count match
between runs, ensuring stale values from different configurations
are discarded.

* test(agents): enhance OpenAI test mocks for summarization handlers

Updated the OpenAI test suite to include additional mock implementations for summarization handlers, including buildSummarizationHandlers, markSummarizationUsage, and agentLogHandlerObj. This improves test coverage and ensures consistent behavior during testing.

* fix(agents): address review findings for summarization v2

Cancel rAF on unmount to prevent stale Recoil writes from dead
component context. Clear orphaned summarizing:true parts when
ON_SUMMARIZE_COMPLETE arrives without a summary payload. Add null
guard and safe spread to agentLogHandler. Handle Anthropic-format
base64 image/* documents in estimateMediaTokensForMessage. Use
role="region" for expandable summary content. Add .describe() to
contextMeta Zod fields. Extract duplicate usage loop into helper.

* refactor: simplify contextMeta to calibrationRatio + encoding only

Remove instructionOverhead and toolCount from cross-run persistence —
instruction tokens change too frequently between runs (prompt edits,
tool changes) for a persisted seed to be reliable. The intra-run
calibration in the pruner still self-corrects via provider observations.
contextMeta now stores only the tokenizer-bias ratio and encoding,
which are stable across instruction changes.

* test(SSE): enhance useStepHandler tests for ON_SUMMARIZE_COMPLETE behavior

Updated the test for ON_SUMMARIZE_COMPLETE to clarify that it finalizes the existing part with summarizing set to false when the summary is undefined. Added assertions to verify the correct behavior of message updates and the state of summary parts.

* refactor(BaseClient): remove handleContextStrategy and truncateToolCallOutputs functions

Eliminated the handleContextStrategy method from BaseClient to streamline message handling. Also removed the truncateToolCallOutputs function from the prompts module, simplifying the codebase and improving maintainability.

* refactor: add AGENT_DEBUG_LOGGING option and refactor token count handling in BaseClient

Introduced AGENT_DEBUG_LOGGING to .env.example for enhanced debugging capabilities. Refactored token count handling in BaseClient by removing the handleTokenCountMap method and simplifying token count updates. Updated AgentClient to log detailed token count recalculations and adjustments, improving traceability during message processing.

* chore: update dependencies in package-lock.json and package.json files

Bumped versions of several dependencies, including @librechat/agents to ^3.1.62 and various AWS SDK packages to their latest versions. This ensures compatibility and incorporates the latest features and fixes.

* chore: imports order

* refactor: extract summarization config resolution from buildAgentContext

* refactor: rename and simplify summarization configuration shaping function

* refactor: replace AgentClient token counting methods with single-pass pure utility

Extract getTokenCount() and getTokenCountForMessage() from AgentClient
into countFormattedMessageTokens(), a pure function in packages/api that
handles text, tool_call, image, and document content types in one loop.

- Decompose estimateMediaTokensForMessage into block-level helpers
  (estimateImageDataTokens, estimateImageBlockTokens, estimateDocumentBlockTokens)
  shared by both estimateMediaTokensForMessage and the new single-pass function
- Remove redundant per-call getEncoding() resolution (closure captures once)
- Remove deprecated gpt-3.5-turbo-0301 model branching
- Drop this.getTokenCount guard from BaseClient.sendMessage

* refactor: streamline token counting in createTokenCounter function

Simplified the createTokenCounter function by removing the media token estimation and directly calculating the token count. This change enhances clarity and performance by consolidating the token counting logic into a single pass, while maintaining compatibility with Claude's token correction.

* refactor: simplify summarization configuration types

Removed the AppSummarizationConfig type and directly used SummarizationConfig in the AppConfig interface. This change streamlines the type definitions and enhances consistency across the codebase.

* chore: import order

* fix: summarization event handling in useStepHandler

- Cancel pending summarizeDeltaRaf in clearStepMaps to prevent stale
  frames firing after map reset or component unmount
- Move announcePolite('summarize_completed') inside the didFinalize
  guard so screen readers only announce when finalization actually occurs
- Remove dead cleanup closure returned from stepHandler useCallback body
  that was never invoked by any caller

* fix: estimate tokens for non-PDF/non-image base64 document blocks

Previously estimateDocumentBlockTokens returned 0 for unrecognized MIME
types (e.g. text/plain, application/json), silently underestimating
context budget. Fall back to character-based heuristic or countTokens.

* refactor: return cloned usage from markSummarizationUsage

Avoid mutating LangChain's internal usage_metadata object by returning
a shallow clone with the usage_type tag. Update all call sites in
callbacks, openai, and responses controllers to use the returned value.

* refactor: consolidate debug logging loops in buildMessages

Merge the two sequential O(n) debug-logging passes over orderedMessages
into a single pass inside the map callback where all data is available.

* refactor: narrow SummaryContentPart.content type

Replace broad Agents.MessageContentComplex[] with the specific
Array<{ type: ContentTypes.TEXT; text: string }> that all producers
and consumers already use, improving compile-time safety.

* refactor: use single output array in recordCollectedUsage

Have processUsageGroup append to a shared array instead of returning
separate arrays that are spread into a third, reducing allocations.

* refactor: use for...in in hydrateMissingIndexTokenCounts

Replace Object.entries with for...in to avoid allocating an
intermediate tuple array during token map hydration.

🐘 feat: FerretDB Compatibility (#11769)
* feat: replace unsupported MongoDB aggregation operators for FerretDB compatibility

Replace $lookup, $unwind, $sample, $replaceRoot, and $addFields aggregation
stages which are unsupported on FerretDB v2.x (postgres-documentdb backend).

- Prompt.js: Replace $lookup/$unwind/$project pipelines with find().select().lean()
  + attachProductionPrompts() batch helper. Replace $group/$replaceRoot/$sample
  in getRandomPromptGroups with distinct() + Fisher-Yates shuffle.
- Agent/Prompt migration scripts: Replace $lookup anti-join pattern with
  distinct() + $nin two-step queries for finding un-migrated resources.

All replacement patterns verified against FerretDB v2.7.0.

* fix: use $pullAll for simple array removals, fix memberIds type mismatches

Replace $pull with $pullAll for exact-value scalar array removals. Both
operators work on MongoDB and FerretDB, but $pullAll is more explicit for
exact matching (no condition expressions).

Fix critical type mismatch bugs where ObjectId values were used against
String[] memberIds arrays in Group queries:
- config/delete-user.js: use string uid instead of ObjectId user._id
- e2e/setup/cleanupUser.ts: convert userId.toString() before query

Harden PermissionService.bulkUpdateResourcePermissions abort handling to
prevent crash when abortTransaction is called after commitTransaction.

All changes verified against FerretDB v2.7.0 and MongoDB Memory Server.

* fix: harden transaction support probe for FerretDB compatibility

Commit the transaction before aborting in supportsTransactions probe, and
wrap abortTransaction in try-catch to prevent crashes when abort is called
after a successful commit (observed behavior on FerretDB).

* feat: add FerretDB compatibility test suite, retry utilities, and CI config

Add comprehensive FerretDB integration test suite covering:
- $pullAll scalar array operations
- $pull with subdocument conditions
- $lookup replacement (find + manual join)
- $sample replacement (distinct + Fisher-Yates)
- $bit and $bitsAllSet operations
- Migration anti-join pattern
- Multi-tenancy (useDb, scaling, write amplification)
- Sharding proof-of-concept
- Production operations (backup/restore, schema migration, deadlock retry)

Add production retryWithBackoff utility for deadlock recovery during
concurrent index creation on FerretDB/DocumentDB backends.

Add UserController.spec.js tests for deleteUserController (runs in CI).

Configure jest and eslint to isolate FerretDB tests from CI pipelines:
- packages/data-schemas/jest.config.mjs: ignore misc/ directory
- eslint.config.mjs: ignore packages/data-schemas/misc/

Include Docker Compose config for local FerretDB v2.7 + postgres-documentdb,
dedicated jest/tsconfig for the test files, and multi-tenancy findings doc.

* style: brace formatting in aclEntry.ts modifyPermissionBits

* refactor: reorganize retry utilities and update imports

- Moved retryWithBackoff utility to a new file `retry.ts` for better structure.
- Updated imports in `orgOperations.ferretdb.spec.ts` to reflect the new location of retry utilities.
- Removed old import statement for retryWithBackoff from index.ts to streamline exports.

* test: add $pullAll coverage for ConversationTag and PermissionService

Add integration tests for deleteConversationTag verifying $pullAll
removes tags from conversations correctly, and for
syncUserEntraGroupMemberships verifying $pullAll removes user from
non-matching Entra groups while preserving local group membership.

🪪 fix: Enforce Conversation Ownership Checks in Remote Agent Controllers (#12263)
* 🔒 fix: Validate conversation ownership in remote agent API endpoints

Add user-scoped ownership checks for client-supplied conversation IDs
in OpenAI-compatible and Open Responses controllers to prevent
cross-tenant file/message loading via IDOR.

* 🔒 fix: Harden ownership checks against type confusion and unhandled errors

- Add typeof string validation before getConvo to block NoSQL operator
  injection (e.g. { "$gt": "" }) bypassing the ownership check
- Move ownership checks inside try/catch so DB errors produce structured
  JSON error responses instead of unhandled promise rejections
- Add string type validation for conversation_id and previous_response_id
  in the upstream TS request validators (defense-in-depth)

* 🧪 test: Add coverage for conversation ownership validation in remote agent APIs

- Fix broken getConvo mock in openai.spec.js (was missing entirely)
- Add tests for: owned conversation, unowned (404), non-string type (400),
  absent conversation_id (skipped), and DB error (500) — both controllers

🧱 fix: Enforce Agent Access Control on Context and OCR File Loading (#12253)
* 🔏 fix: Apply agent access control filtering to context/OCR resource loading

The context/OCR file path in primeResources fetched files by file_id
without applying filterFilesByAgentAccess, unlike the file_search and
execute_code paths. Add filterFiles dependency injection to primeResources
and invoke it after getFiles to enforce consistent access control.

* fix: Wire filterFilesByAgentAccess into all agent initialization callers

Pass the filterFilesByAgentAccess function from the JS layer into the TS
initializeAgent → primeResources chain via dependency injection, covering
primary, handoff, added-convo, and memory agent init paths.

* test: Add access control filtering tests for primeResources

Cover filterFiles invocation with context/OCR files, verify filtering
rejects inaccessible files, and confirm graceful fallback when filterFiles,
userId, or agentId are absent.

* fix: Guard filterFilesByAgentAccess against ephemeral agent IDs

Ephemeral agents have no DB document, so getAgent returns null and the
access map defaults to all-false, silently blocking all non-owned files.
Short-circuit with isEphemeralAgentId to preserve the pass-through
behavior for inline-built agents (memory, tool agents).

* fix: Clean up resources.ts and JS caller import order

Remove redundant optional chain on req.user.role inside user-guarded
block, update primeResources JSDoc with filterFiles and agentId params,
and reorder JS imports to longest-to-shortest per project conventions.

* test: Strengthen OCR assertion and add filterFiles error-path test

Use toHaveBeenCalledWith for the OCR filtering test to verify exact
arguments after the OCR→context merge step. Add test for filterFiles
rejection to verify graceful degradation (logs error, returns original
tool_resources).

* fix: Correct import order in addedConvo.js and initialize.js

Sort by total line length descending: loadAddedAgent (91) before
filterFilesByAgentAccess (84), loadAgentTools (91) before
filterFilesByAgentAccess (84).

* test: Add unit tests for filterFilesByAgentAccess and hasAccessToFilesViaAgent

Cover every branch in permissions.js: ephemeral agent guard, missing
userId/agentId/files early returns, all-owned short-circuit, mixed
owned + non-owned with VIEW/no-VIEW, agent-not-found fail-closed,
author path scoped to attached files, EDIT gate on delete, DB error
fail-closed, and agent with no tool_resources.

* test: Cover file.user undefined/null in permissions spec

Files with no user field fall into the non-owned path and get run
through hasAccessToFilesViaAgent. Add two cases: attached file with
no user field is returned, unattached file with no user field is
excluded.

🛂 fix: Enforce Actions Capability Gate Across All Event-Driven Tool Loading Paths (#12252)
* fix: gate action tools by actions capability in all code paths

Extract resolveAgentCapabilities helper to eliminate 3x-duplicated
capability resolution. Apply early action-tool filtering in both
loadToolDefinitionsWrapper and loadAgentTools non-definitions path.
Gate loadActionToolsForExecution in loadToolsForExecution behind an
actionsEnabled parameter with a cache-based fallback. Replace the
late capability guard in loadAgentTools with a hasActionTools check
to avoid unnecessary loadActionSets DB calls and duplicate warnings.

* fix: thread actionsEnabled through InitializedAgent type

Add actionsEnabled to the loadTools callback return type,
InitializedAgent, and the initializeAgent destructuring/return
so callers can forward the resolved value to loadToolsForExecution
without redundant getEndpointsConfig cache lookups.

* fix: pass actionsEnabled from callers to loadToolsForExecution

Thread actionsEnabled through the agentToolContexts map in
initialize.js (primary and handoff agents) and through
primaryConfig in the openai.js and responses.js controllers,
avoiding per-tool-call capability re-resolution on the hot path.

* test: add regression tests for action capability gating

Test the real exported functions (resolveAgentCapabilities,
loadAgentTools, loadToolsForExecution) with mocked dependencies
instead of shadow re-implementations. Covers definition filtering,
execution gating, actionsEnabled param forwarding, and fallback
capability resolution.

* test: use Constants.EPHEMERAL_AGENT_ID in ephemeral fallback test

Replaces a string guess with the canonical constant to avoid
fragility if the ephemeral detection heuristic changes.

* fix: populate agentToolContexts for addedConvo parallel agents

After processAddedConvo returns, backfill agentToolContexts for
any agents in agentConfigs not already present, so ON_TOOL_EXECUTE
for added-convo agents receives actionsEnabled instead of falling
back to a per-call cache lookup.

🔏 fix: Enforce MCP Server Authorization on Agent Tool Persistence (#12250)
* 🛡️ fix: Validate MCP tool authorization on agent create/update

Agent creation and update accepted arbitrary MCP tool strings without
verifying the user has access to the referenced MCP servers. This allowed
a user to embed unauthorized server names in tool identifiers (e.g.
"anything_mcp_<victimServer>"), causing mcpServerNames to be stored on
the agent and granting consumeOnly access via hasAccessViaAgent().

Adds filterAuthorizedTools() that checks MCP tool strings against the
user's accessible server configs (via getAllServerConfigs) before
persisting. Applied to create, update, and duplicate agent paths.

* 🛡️ fix: Harden MCP tool authorization and add test coverage

Addresses review findings on the MCP agent tool authorization fix:

- Wrap getMCPServersRegistry() in try/catch so uninitialized registry
  gracefully filters all MCP tools instead of causing a 500 (DoS risk)
- Guard revertAgentVersionHandler: filter unauthorized MCP tools after
  reverting to a previous version snapshot
- Preserve existing MCP tools on collaborative updates: only validate
  newly added tools, preventing silent stripping of tools the editing
  user lacks direct access to
- Add audit logging (logger.warn) when MCP tools are rejected
- Refactor to single-pass lazy-fetch (registry queried only on first
  MCP tool encountered)
- Export filterAuthorizedTools for direct unit testing
- Add 18 tests covering: authorized/unauthorized/mixed tools, registry
  unavailable fallback, create/update/duplicate/revert handler paths,
  collaborative update preservation, and mcpServerNames persistence

* test: Add duplicate handler test, use Constants.mcp_delimiter, DB assertions

- N1: Add duplicateAgentHandler integration test verifying unauthorized
  MCP tools are stripped from the cloned agent and mcpServerNames are
  correctly persisted in the database
- N2: Replace all hardcoded '_mcp_' delimiter literals with
  Constants.mcp_delimiter to prevent silent false-positive tests if
  the delimiter value ever changes
- N3: Add DB state assertion to the revert-with-strip test confirming
  persisted tools match the response after unauthorized tools are
  removed

* fix: Enforce exact 2-segment format for MCP tool keys

Reject MCP tool keys with multiple delimiters to prevent
authorization/execution mismatch when `.pop()` vs `split[1]`
extract different server names from the same key.

* fix: Preserve existing MCP tools when registry is unavailable

When the MCP registry is uninitialized (e.g. server restart), existing
tools already persisted on the agent are preserved instead of silently
stripped. New MCP tools are still rejected when the registry cannot
verify them. Applies to duplicate and revert handlers via existingTools
param; update handler already preserves existing tools via its diff logic.

🪪 fix: Enforce VIEW ACL on Agent Edge References at Write and Runtime (#12246)
* 🛡️ fix: Enforce ACL checks on handoff edge and added-convo agent loading

Edge-linked agents and added-convo agents were fetched by ID via
getAgent without verifying the requesting user's access permissions.
This allowed an authenticated user to reference another user's private
agent in edges or addedConvo and have it initialized at runtime.

Add checkPermission(VIEW) gate in processAgent before initializing
any handoff agent, and in processAddedConvo for non-ephemeral added
agents. Unauthorized agents are logged and added to skippedAgentIds
so orphaned-edge filtering removes them cleanly.

* 🛡️ fix: Validate edge agent access at agent create/update time

Reject agent create/update requests that reference agents in edges
the requesting user cannot VIEW. This provides early feedback and
prevents storing unauthorized agent references as defense-in-depth
alongside the runtime ACL gate in processAgent.

Add collectEdgeAgentIds utility to extract all unique agent IDs from
an edge array, and validateEdgeAgentAccess helper in the v1 handler.

* 🧪 test: Improve ACL gate test coverage and correctness

- Add processAgent ACL gate tests for initializeClient (skip/allow handoff agents)
- Fix addedConvo.spec.js to mock loadAddedAgent directly instead of getAgent
- Seed permMap with ownedAgent VIEW bits in v1.spec.js update-403 test

* 🧹 chore: Remove redundant addedConvo ACL gate (now in middleware)

PR #12243 moved the addedConvo agent ACL check upstream into
canAccessAgentFromBody middleware, making the runtime check in
processAddedConvo and its spec redundant.

* 🧪 test: Rewrite processAgent ACL test with real DB and minimal mocking

Replace heavy mock-based test (12 mocks, Providers.XAI crash) with
MongoMemoryServer-backed integration test that exercises real getAgent,
checkPermission, and AclEntry — only external I/O (initializeAgent,
ToolService, AgentClient) remains mocked. Load edge utilities directly
from packages/api/src/agents/edges to sidestep the config.ts barrel.

* 🧪 fix: Use requireActual spread for @librechat/agents and @librechat/api mocks

The Providers.XAI crash was caused by mocking @librechat/agents with
a minimal replacement object, breaking the @librechat/api initialization
chain. Match the established pattern from client.test.js and
recordCollectedUsage.spec.js: spread jest.requireActual for both
packages, overriding only the functions under test.

🛡️ refactor: Scope Action Mutations by Parent Resource Ownership (#12237)
* 🛡️ fix: Scope action mutations by parent resource ownership

Prevent cross-tenant action overwrites by validating that an existing
action's agent_id/assistant_id matches the URL parameter before allowing
updates or deletes. Without this, a user with EDIT access on their own
agent could reference a foreign action_id to hijack another agent's
action record.

* 🛡️ fix: Harden action ownership checks and scope write filters

- Remove && short-circuit that bypassed the guard when agent_id or
  assistant_id was falsy (e.g. assistant-owned actions have no agent_id,
  so the check was skipped entirely on the agents route).
- Include agent_id / assistant_id in the updateAction and deleteAction
  query filters so the DB write itself enforces ownership atomically.
- Log a warning when deleteAction returns null (silent no-op from
  data-integrity mismatch).

* 📝 docs: Update Action model JSDoc to reflect scoped query params

*  test: Add Action ownership scoping tests

Cover update, delete, and cross-type protection scenarios using
MongoMemoryServer to verify that scoped query filters (agent_id,
assistant_id) prevent cross-tenant overwrites and deletions at the
database level.

* 🛡️ fix: Scope updateAction filter in agent duplication handler

* 🐛 fix: Use action metadata domain instead of action_id when duplicating agent actions

The duplicate handler was splitting `action.action_id` by `actionDelimiter`
to extract the domain, but `action_id` is a bare nanoid that doesn't
contain the delimiter. This produced malformed entries in the duplicated
agent's actions array (nanoid_action_newNanoid instead of
domain_action_newNanoid). The domain is available on `action.metadata.domain`.

*  test: Add integration tests for agent duplication action handling

Uses MongoMemoryServer with real Agent and Action models to verify:
- Duplicated actions use metadata.domain (not action_id) for the
  agent actions array entries
- Sensitive metadata fields are stripped from duplicated actions
- Original action documents are not modified

- Updated Tokenizer class to utilize 'ai-tokenizer' for both 'o200k_base' and 'claude' encodings, replacing the previous 'tiktoken' dependency.
- Refactored tests to reflect changes in tokenizer behavior and ensure accurate token counting for both encoding types.
- Removed deprecated references to 'tiktoken' and adjusted related tests for improved clarity and functionality.

* chore: remove tiktoken mocks from DALLE3 tests

- Eliminated mock implementations of 'tiktoken' from DALLE3-related test files to streamline test setup and align with recent dependency updates.
- Adjusted related test structures to ensure compatibility with the new tokenizer implementation.

* chore: Add distinct encoding support for Anthropic Claude models

- Introduced a new method `getEncoding` in the AgentClient class to handle the specific BPE tokenizer for Claude models, ensuring compatibility with the distinct encoding requirements.
- Updated documentation to clarify the encoding logic for Claude and other models.

* docs: Update return type documentation for getEncoding method in AgentClient

- Exported the EncodingName type for broader usage.
- Renamed encodingMap to encodingData for clarity.
- Improved error handling in getTokenCount method to ensure recovery attempts are logged and return 0 on failure.
- Updated countTokens function documentation to specify the use of 'o200k_base' encoding.

* refactor: Simplify encoding documentation and export type

- Updated the getEncoding method documentation to clarify the default behavior for non-Anthropic Claude models.
- Exported the EncodingName type separately from the Tokenizer module for improved clarity and usage.

* test: Update text processing tests for token limits

- Adjusted test cases to handle smaller text sizes, changing scenarios from ~120k tokens to ~20k tokens for both the real tokenizer and countTokens functions.
- Updated token limits in tests to reflect new constraints, ensuring tests accurately assess performance and call reduction.
- Enhanced console log messages for clarity regarding token counts and reductions in the updated scenarios.

* refactor: Update Tokenizer imports and exports

- Moved Tokenizer and countTokens exports to the tokenizer module for better organization.
- Adjusted imports in memory.ts to reflect the new structure, ensuring consistent usage across the codebase.
- Updated memory.test.ts to mock the Tokenizer from the correct module path, enhancing test accuracy.

- Updated `getTokenCount` to handle uninitialized tokenizers more gracefully, ensuring proper recovery and logging on errors.
- Removed deprecated synchronous tokenizer retrieval, streamlining the overall tokenizer management process.

* test: Enhance tokenizer tests with initialization and encoding checks

- Added `beforeAll` hooks to initialize tokenizers for 'o200k_base' and 'claude' encodings before running tests, ensuring proper setup.
- Updated tests to validate the loading of encodings and the correctness of token counts for both 'o200k_base' and 'claude'.
- Improved test structure to deduplicate concurrent initialization calls, enhancing performance and reliability.

🧮 refactor: Bulk Transactions & Balance Updates for Token Spending (#11996)
* refactor: transaction handling by integrating pricing and bulk write operations

- Updated `recordCollectedUsage` to accept pricing functions and bulk write operations, improving transaction management.
- Refactored `AgentClient` and related controllers to utilize the new transaction handling capabilities, ensuring better performance and accuracy in token spending.
- Added tests to validate the new functionality, ensuring correct behavior for both standard and bulk transaction paths.
- Introduced a new `transactions.ts` file to encapsulate transaction-related logic and types, enhancing code organization and maintainability.

* chore: reorganize imports in agents client controller

- Moved `getMultiplier` and `getCacheMultiplier` imports to maintain consistency and clarity in the import structure.
- Removed duplicate import of `updateBalance` and `bulkInsertTransactions`, streamlining the code for better readability.

* refactor: add TransactionData type and CANCEL_RATE constant to data-schemas

Establishes a single source of truth for the transaction document shape
and the incomplete-context billing rate constant, both consumed by
packages/api and api/.

* refactor: use proper types in data-schemas transaction methods

- Replace `as unknown as { tokenCredits }` with `lean<IBalance>()`
- Use `TransactionData[]` instead of `Record<string, unknown>[]`
  for bulkInsertTransactions parameter
- Add JSDoc noting insertMany bypasses document middleware
- Remove orphan section comment in methods/index.ts

* refactor: use shared types in transactions.ts, fix bulk write logic

- Import CANCEL_RATE from data-schemas instead of local duplicate
- Import TransactionData from data-schemas for PreparedEntry/BulkWriteDeps
- Use tilde alias for EndpointTokenConfig import
- Pass valueKey through to getMultiplier
- Only sum tokenValue for balance-enabled docs in bulkWriteTransactions
- Consolidate two loops into single-pass map

* refactor: remove duplicate updateBalance from Transaction.js

Import updateBalance from ~/models (sourced from data-schemas) instead
of maintaining a second copy. Also import CANCEL_RATE from data-schemas
and remove the Balance model import (no longer needed directly).

* fix: test real spendCollectedUsage instead of IIFE replica

Export spendCollectedUsage from abortMiddleware.js and rewrite the test
file to import and test the actual function. Previously the tests ran
against a hand-written replica that could silently diverge from the real
implementation.

* test: add transactions.spec.ts and restore regression comments

Add 22 direct unit tests for transactions.ts financial logic covering
prepareTokenSpend, prepareStructuredTokenSpend, bulkWriteTransactions,
CANCEL_RATE paths, NaN guards, disabled transactions, zero tokens,
cache multipliers, and balance-enabled filtering.

Restore critical regression documentation comments in
recordCollectedUsage.spec.js explaining which production bugs the
tests guard against.

* fix: widen setValues type to include lastRefill

The UpdateBalanceParams.setValues type was Partial<Pick<IBalance,
'tokenCredits'>> which excluded lastRefill — used by
createAutoRefillTransaction. Widen to also pick 'lastRefill'.

* test: use real MongoDB for bulkWriteTransactions tests

Replace mock-based bulkWriteTransactions tests with real DB tests using
MongoMemoryServer. Pure function tests (prepareTokenSpend,
prepareStructuredTokenSpend) remain mock-based since they don't touch
DB. Add end-to-end integration tests that verify the full prepare →
bulk write → DB state pipeline with real Transaction and Balance models.

* chore: update @librechat/agents dependency to version 3.1.54 in package-lock.json and related package.json files

* test: add bulk path parity tests proving identical DB outcomes

Three test suites proving the bulk path (prepareTokenSpend/
prepareStructuredTokenSpend + bulkWriteTransactions) produces
numerically identical results to the legacy path for all scenarios:

- usage.bulk-parity.spec.ts: mirrors all legacy recordCollectedUsage
  tests; asserts same return values and verifies metadata fields on
  the insertMany docs match what spendTokens args would carry

- transactions.bulk-parity.spec.ts: real-DB tests using actual
  getMultiplier/getCacheMultiplier pricing functions; asserts exact
  tokenValue, rate, rawAmount and balance deductions for standard
  tokens, structured/cache tokens, CANCEL_RATE, premium pricing,
  multi-entry batches, and edge cases (NaN, zero, disabled)

- Transaction.spec.js: adds describe('Bulk path parity') that mirrors
  7 key legacy tests via recordCollectedUsage + bulk deps against
  real MongoDB, asserting same balance deductions and doc counts

* refactor: update llmConfig structure to use modelKwargs for reasoning effort

Refactor the llmConfig in getOpenAILLMConfig to store reasoning effort within modelKwargs instead of directly on llmConfig. This change ensures consistency in the configuration structure and improves clarity in the handling of reasoning properties in the tests.

* test: update performance checks in processAssistantMessage tests

Revise the performance assertions in the processAssistantMessage tests to ensure that each message processing time remains under 100ms, addressing potential ReDoS vulnerabilities. This change enhances the reliability of the tests by focusing on maximum processing time rather than relative ratios.

* test: fill parity test gaps — model fallback, abort context, structured edge cases

- usage.bulk-parity: add undefined model fallback test
- transactions.bulk-parity: add abort context test (txns inserted,
  balance unchanged when balance not passed), fix readTokens type cast
- Transaction.spec: add 3 missing mirrors — balance disabled with
  transactions enabled, structured transactions disabled, structured
  balance disabled

* fix: deduct balance before inserting transactions to prevent orphaned docs

Swap the order in bulkWriteTransactions: updateBalance runs before
insertMany. If updateBalance fails (after exhausting retries), no
transaction documents are written — avoiding the inconsistent state
where transactions exist in MongoDB with no corresponding balance
deduction.

* chore: import order

* test: update config.spec.ts for OpenRouter reasoning in modelKwargs

Same fix as llm.spec.ts — OpenRouter reasoning is now passed via
modelKwargs instead of llmConfig.reasoning directly.

Docker Dev Branch Images Build / build (Dockerfile.multi, lc-dev-api, api-build) (push) Waiting to run
* fix: store hide_sequential_outputs before processStream clears config

processStream now clears config.configurable after completion to break
memory retention chains. Save hide_sequential_outputs to a local
variable before calling runAgents so the post-stream filter still works.

* feat: memory diagnostics

* chore: expose garbage collection in backend inspect command

Updated the backend inspect command in package.json to include the --expose-gc flag, enabling garbage collection diagnostics for improved memory management during development.

* chore: update @librechat/agents dependency to version 3.1.52

Bumped the version of @librechat/agents in package.json and package-lock.json to ensure compatibility and access to the latest features and fixes.

* fix: clear heavy config state after processStream to prevent memory leaks

Break the reference chain from LangGraph's internal __pregel_scratchpad
through @langchain/core RunTree.extra[lc:child_config] into the
AsyncLocalStorage context captured by timers and I/O handles.

After stream completion, null out symbol-keyed scratchpad properties
(currentTaskInput), config.configurable, and callbacks. Also call
Graph.clearHeavyState() to release config, signal, content maps,
handler registry, and tool sessions.

* chore: fix imports for memory utils

* chore: add circular dependency check in API build step

Enhanced the backend review workflow to include a check for circular dependencies during the API build process. If a circular dependency is detected, an error message is displayed, and the process exits with a failure status.

* chore: update API build step to include circular dependency detection

Modified the backend review workflow to rename the API package installation step to reflect its new functionality, which now includes detection of circular dependencies during the build process.

* chore: add memory diagnostics option to .env.example

Included a commented-out configuration option for enabling memory diagnostics in the .env.example file, which logs heap and RSS snapshots every 60 seconds when activated.

Docker Dev Branch Images Build / build (Dockerfile.multi, lc-dev-api, api-build) (push) Has been cancelled
* fix: serve cached presigned URLs on agent list cache hits

  On a cache hit the list endpoint was skipping the S3 refresh and
  returning whatever presigned URL was stored in MongoDB, which could be
  expired if the S3 URL TTL is shorter than the 30-minute cache window.

  refreshListAvatars now collects a urlCache map (agentId -> refreshed
  filepath) alongside its existing stats. The controller stores this map
  in the cache instead of a plain boolean and re-applies it to every
  paginated response, guaranteeing clients always receive a URL that was
  valid as of the last refresh rather than a potentially stale DB value.

* fix: improve avatar refresh cache handling and logging

Updated the avatar refresh logic to validate cached refresh data before proceeding with S3 URL updates. Enhanced logging to exclude sensitive `urlCache` details while still providing relevant statistics. Added error handling for cache invalidation during avatar updates to ensure robustness.

* fix: update avatar refresh logic to clear urlCache on no change

Modified the avatar refresh function to clear the urlCache when no new path is generated, ensuring that stale URLs are not retained. This change improves cache handling and aligns with the updated logic for avatar updates.

* fix: enhance avatar refresh logic to handle legacy cache entries

Updated the avatar refresh logic to accommodate legacy boolean cache entries, ensuring they are treated as cache misses and triggering a refresh. The cache now stores a structured `urlCache` map instead of a boolean, improving cache handling. Added tests to verify correct behavior for cache hits and misses, ensuring clients receive valid URLs based on the latest refresh.

🐛 fix: Normalize output_text blocks in Responses API input conversion (#11835)
* 🐛 fix: Normalize `output_text` blocks in Responses API input conversion

Treat `output_text` content blocks the same as `input_text` when
converting Responses API input to internal message format. Previously,
assistant messages containing `output_text` blocks fell through to the
default handler, producing `{ type: 'output_text' }` without a `text`
field, which caused downstream provider adapters (e.g. Bedrock) to fail
with "Unsupported content block type: output_text".

* refactor: Remove ChatModelStreamHandler from OpenAI and Responses controllers

Eliminated the ChatModelStreamHandler from both OpenAIChatCompletionController and createResponse functions to streamline event handling. This change simplifies the code by relying on existing handlers for message deltas and reasoning deltas, enhancing maintainability and reducing complexity in the agent's event processing logic.

* feat: Enhance input conversion in Responses API

Updated the `convertInputToMessages` function to handle additional content types, including `input_file` and `refusal` blocks, ensuring they are converted to appropriate message formats. Implemented null filtering for content arrays and default values for missing fields, improving robustness. Added comprehensive unit tests to validate these changes and ensure correct behavior across various input scenarios.

* fix: Forward upstream provider status codes in error responses

Updated error handling in OpenAIChatCompletionController and createResponse functions to forward upstream provider status codes (e.g., Anthropic 400s) instead of masking them as 500. This change improves error reporting by providing more accurate status codes and error types, enhancing the clarity of error responses for clients.

    Removed direct handling of tool calls from the ModelEndHandler and using ChatModelStreamHandler  outside of graph contexts, as are now managed within the graph execution context to maintain it as a producer of events, and the model end handler as a consumer. This change eliminates potential race conditions and streamlines the processing of model end events.

          /**
       * handleToolCalls is now called from within the graph execution context
       * (Graph.createCallModel, after attemptInvoke) rather than here in the

* style: improve image preview dialogs with ChatGPT-like UX and accessibility

Refactored image preview dialogs (DialogImage and ImagePreview) to provide
a cleaner, more intuitive user experience similar to ChatGPT's implementation.

## DialogImage.tsx (generated images)
- Replaced OGDialog/OGDialogContent with direct Radix Dialog primitives
  for finer control over behavior
- Full-screen dark overlay (bg-black/90) that closes on click outside image
- Restructured component so all interactive elements (close, download,
  details panel buttons) are inside DialogPrimitive.Content for proper
  focus trap and keyboard navigation
- Added onOpenAutoFocus to focus close button when dialog opens
- Added onCloseAutoFocus to return focus to trigger element on close
- Added triggerRef prop to enable focus restoration
- Removed animate-in/animate-out classes that caused stuttering on open
- Changed transition-all to transition-[margin] to prevent animation jank
- Added proper TypeScript types for component props

## ImagePreview.tsx (uploaded file thumbnails)
- Same Radix Dialog primitive refactor for consistent behavior
- Click-outside-to-close functionality
- Proper focus management with closeButtonRef and triggerRef
- Made button the container element to prevent focus ring clipping
- Added focus-visible ring styling for keyboard navigation visibility

## Image.tsx (image display component)
- Restructured so button is the outer container instead of being nested
  inside a div with overflow-hidden (which was clipping focus ring)
- Added visible focus-visible:ring styling with ring-offset
- Added aria-haspopup="dialog" for screen reader context
- Added triggerRef and passed to DialogImage for focus restoration

## Accessibility improvements
- Keyboard navigation now works properly (Tab cycles through buttons)
- Escape key closes dialog (or resets zoom if zoomed in)
- Focus is trapped within dialog when open
- Focus returns to trigger element when dialog closes
- Visible focus indicators on image buttons when focused via keyboard
- Proper ARIA attributes (aria-label, aria-haspopup, aria-hidden)

## UX improvements
- Click anywhere outside the image to close (not just specific regions)
- No more weird scroll/navigation issues
- Instant dialog open without stuttering animations
- Clean, minimal overlay without container/header chrome

* refactor: Improve click handling in image preview dialogs

Updated the click handling logic in ImagePreview and DialogImage components to ensure that the dialog only closes when clicking directly on the overlay or content background, enhancing user experience by preventing unintended closures when interacting with child elements. Additionally, clarified comments to reflect the new behavior.

* chore: import order
