fix: add default value to grep tool glob schema for strict mode compatibility ( #422 )
...
* fix: add default value to grep tool glob schema for strict mode compatibility
The grep tool's `glob` field was defined with `.optional().nullable()` but
without `.default()`, causing it to be excluded from the JSON schema
`required` array. This violates OpenAI's strict mode requirement that all
properties must be listed in `required`.
Fixes #401
* Fix grep tool glob schema for strict mode
Added a default value to the grep tool glob schema to ensure compatibility with strict mode.
* Update .changeset/lucky-candles-reply.md

* feat(deepagents): add completion notifier middleware for async subagents (#334 )
Port of langchain-ai/deepagents#2119 to TypeScript. Adds a
createCompletionNotifierMiddleware that async subagents can use to
proactively notify their supervisor when they complete or error,
closing the gap where the supervisor only learns about completion
when someone calls check_async_task.
- New createCompletionNotifierMiddleware with afterAgent and
wrapModelCall hooks
- Uses @langchain/langgraph-sdk Client to send runs.create() to the
supervisor's thread
- Reads parent_thread_id from subagent state (injected by
start_async_task)
- Derives task_id from runtime.configurable.thread_id
- Silently no-ops if parent context is missing
- Guards against duplicate notifications
- 22 unit tests covering all hooks, edge cases, and error paths
fix(deepagents): make url required in completion notifier (no ASGI in JS)
JS does not have ASGI transport like Python, so the url parameter
must be provided explicitly. Removed all ASGI references from docs
and the localhost fallback default.

* feat(deepagents): rename completion notifier to completion callback and align with Python PR
- Rename completion_notifier.ts -> completion_callback.ts to match Python's
completion_callback.py naming
- Rename exports: createCompletionNotifierMiddleware -> createCompletionCallbackMiddleware,
CompletionNotifierOptions -> CompletionCallbackOptions
- Rename state key: parent_thread_id -> callbackThreadId, option: parentGraphId -> callbackGraphId
- Make url optional (Python allows omitting for ASGI transport)
- Match Python's strict error behavior: throw on empty messages, non-AIMessage types,
and missing callbackThreadId
- Add truncation suffix with task_id hint for long messages
- Use generic error message in wrapModelCall (don't leak error details)
- Remove duplicate notification guard (Python notifies on every error)
- Add extractCallbackContext to async_subagents.ts: injects callbackThreadId
into subagent input state when launching via start_async_task
- Add tests for extractCallbackContext and callback context injection

Renamed completion notifier to completion callback for consistency with Python.

fix(deepagents): evict large HumanMessages to filesystem ( #357 )
...
* feat(sdk): evict large HumanMessages to filesystem
Port of python PR #2183 to JS. Adds a beforeAgent hook to the
FilesystemMiddleware that checks the most recent message. If it is a
HumanMessage whose text content exceeds toolTokenLimitBeforeEvict, the
full content is written to the backend and the message is replaced with
a truncated preview pointing to the file.
Changes:
- Add TOO_LARGE_HUMAN_MSG template for evicted human messages
- Add extractTextFromMessage() to extract text from any message type
- Add buildEvictedHumanContent() to preserve non-text blocks (images)
- Add beforeAgent hook to createFilesystemMiddleware
- Add comprehensive tests for HumanMessage eviction

* format
* Create angry-jobs-film.md
* refactor: align with final Python PR - tag-based eviction architecture
Rework the HumanMessage eviction to match the final shipped Python PR:
Architecture change:
- beforeAgent: writes large content to backend and TAGS the message
with lc_evicted_to in additional_kwargs (preserving original content
in state for checkpoint persistence)
- wrapModelCall: truncates all tagged messages before sending to model
(model sees preview, state keeps full content)
Key differences from initial port:
- Separate humanMessageTokenLimitBeforeEvict option (default: 50000)
- Original content preserved in state (not replaced)
- Messages tagged with lc_evicted_to for multi-turn truncation
- Path changed from /large_messages/ to /conversation_history/
- Added buildTruncatedHumanMessage helper for model-view truncation
- wrapModelCall now handles truncation of all tagged messages
Tests updated:
- beforeAgent tests verify tagging behavior (original content preserved)
- New wrapModelCall test suite for truncation of tagged messages
- Test for skip already-tagged messages
- Test for mixed tagged/untagged message lists
- Test for non-text block preservation during truncation

* fix: update beforeAgent to use resolveBackend after main merge
The merge from main replaced getBackend/StateAndStore with
resolveBackend/BackendRuntime. Update the beforeAgent hook to use the
new API.
