Thushanth Bengre 68337fcca1 fix(deepagents): coerce grep tool's max_count to a number (#751)
Fixes #745 

`max_count` was the only numeric grep param without type coercion,
causing ToolInputParsingException on stringified input. Switched to
z.coerce.number().

Thushanth Bengre 7550c65204 fix(deepagents): exclude summarization state from subagent input/output (#749)
Fixes #748 

Excludes `_summarizationEvent`/`_summarizationSessionId` from subagent
state input/output. These weren't in `EXCLUDED_STATE_KEYS`, so a stale
parent cutoffIndex could silently drop a subagent's task description,
and a subagent's own summarization event could overwrite the parent's on
return.

Caspar Broekhuizen b2afb8d600 fix(deepagents): batch concurrent Context Hub mutations (#747)
ContextHubBackend now preserves concurrent file mutations in one durable
commit and retains compatible remote changes during conflict recovery.

---

Concurrent callers previously reused the same parent commit, causing
409s. Retries could also replay stale edit payloads.

Mutations now coalesce for 50 ms into serialized multi-file commits.
Conflict recovery replays ordered edit intent against refreshed state;
explicit writes, uploads, and deletes remain last-writer-wins.

Wei Tao 1439bbfb26 fix(deepagents): extract text from content blocks when building the summary (#739)
## Description

`SummarizationMiddleware`'s `createSummary` falls back to
`JSON.stringify(response.content)` when the summarization model's
response content is not a string:

```ts
return typeof response.content === "string"
  ? response.content
  : JSON.stringify(response.content);
```

When the summarization model responds with a content block array, the
raw blocks are stringified verbatim into the summary `HumanMessage`.
This happens in practice when:

- **Thinking/reasoning is enabled** on the summarization model (e.g.
Claude on Bedrock with `thinking`): the content is `[{type: "reasoning",
reasoning: ..., signature: <opaque multi-KB signature>}, {type: "text",
...}]`, and the reasoning signature lands in the summary.
- **`invoke()` takes the internal streaming path** (a `prefersStreaming`
callback handler is attached, e.g. inside `streamEvents`, and
`disableStreaming` is not set): the aggregated `AIMessageChunk` content
is an array of many small text fragments.

Observed in production: a summary message of ~56KB consisting of an ~8KB
opaque reasoning signature plus hundreds of
`{"type":"text","text":"..."}` fragments — the "summary" ended up
bloating the context it was supposed to compact, and subsequent model
calls overflowed.

## Fix

Use the message's `text` accessor for non-string content, which extracts
and joins only the text blocks. String content is returned as-is
(unchanged behavior).

## Testing

Added a unit test where the summarization model returns reasoning +
split text blocks, asserting the summary message contains the joined
text and no reasoning payload. All 33 existing tests pass.

gethin-langchain 77e104f26a feat(deepagents): add output_mode parameter to the grep tool (#724)
## Summary
- The grep tool's description mentioned output_mode, but it was never an
actual parameter the tool always returned one hardcoded format.
- Added output_mode (files_with_matches/content/count) as a real schema
parameter, using the existing formatGrepMatches helper.

## Test plan
- Added tests in fs.test.ts for files_with_matches and count modes.
- All tests pass.

Note: default output is now sorted by path with no blank lines between
file groups (minor formatting change, same info).

Hunter Lovell 239be7e883 fix(deepagents): disable summary input trimming by default (#732)
## Summary

Prevent default DeepAgents JS summarization from discarding an oversized
message before it reaches the summary model

## Changes

### `deepagents`

- Make `trimTokensToSummarize` opt-in rather than defaulting to 4,000
tokens.
- Preserve existing capped behavior when callers explicitly configure
the option.
- Add coverage confirming oversized summary input reaches the summary
model under default configuration.
- Add a patch changeset for the bug fix.

thushanth-bengre-langchain 590c2a5042 fix(deepagents): prevent stack overflow in CompositeBackend grep/glob (#723)
## Summary

- Fixes `RangeError: Maximum call stack size exceeded` from
`CompositeBackend.glob`/`grep` when a broad search (e.g.
`**/*.{ts,tsx,...}` at `/`) returns hundreds of thousands of entries.
Root cause: results were merged with `push(...entries)`, which passes
each entry as a separate function argument and overflows V8's
argument-stack limit. Now accumulated with a plain loop.
- Ports the Python SDK's grep match-count cap (`ef591e7`): optional
`maxCount` backend param / `max_count` tool arg, `grepMaxCount`
middleware option (default 1000, `null` disables), `truncated` flag on
`GrepResult`/`GlobResult`, and a truncation note in the grep tool
output. `CompositeBackend` splits the budget across routes and
OR-propagates `truncated`.

## Backward compatibility

- `truncated` is optional; `maxCount` defaults to unset everywhere. No
required changes for existing or new users.

## Test plan

- [x] Regression test: mocked backend returning 200k entries —
`glob`/`grep` complete without `RangeError` (verified it fails with the
old spread).
- [x] Cap enforcement, `truncated` propagation across composite routes,
middleware note rendering.
- [x] `pnpm test` (format + lint + all lib tests) passes.

gethin-langchain ffec5de0e6 fix(deepagents): grep/glob match when path points directly at a file (#713)
## Summary
- `grep`/`glob` on `StateBackend`/`StoreBackend` returned zero matches
whenever `path` pointed at an exact file (no glob) — the shared
`validatePath` helper forced a trailing `/` before prefix-matching, so a
file's own key could never match itself+`/`.
- Added a `filterFilesByPath` helper that checks for an exact key match
in the files map first, falling back to the existing directory-prefix
behavior otherwise.

## Test plan
- [x] Added regression tests in `utils.test.ts`: exact-file path (no
glob) for grep and glob, plus directory + glob/filename non-regression
cases for both.
- [x] `pnpm --filter deepagents test` — all tests pass.

Hunter Lovell 1225a7ff86 feat(deepagents): make todo middleware opt-in (#708)
## Summary

Makes `todoListMiddleware` opt-in. Default agents and default subagents
no longer expose `write_todos` or the `todos` state channel, reducing
the default tool surface while preserving explicit opt-in.

## Changes

- Remove default todo middleware from the main, general-purpose, and
declarative subagent stacks.
- Preserve opt-in support through `middleware: [todoListMiddleware()]`;
declarative subagents opt in through their own middleware.
- Remove `write_todos` from always-present tool typing and built-in
name-collision handling.
- Update state and subagent documentation plus shared runtime assertions
for the optional todo state/tool.

### Harness profiles and coverage

- Re-add todo middleware in the Codex harness profile because its
model-specific prompt requires `write_todos`
- Apply profile `extraMiddleware` to subagent stacks, with profile
factories creating fresh instances per stack.
- Add coverage for default exclusion, explicit opt-in,
main/GP/declarative isolation, profile middleware propagation, and type
inference.

Hunter Lovell d25097f78d feat(deepagents): simplify prompting (#703)
## Summary

The SDK currently ships authored base prose plus middleware guidance
that largely duplicates the tool schemas. This change adopts a more lean
default: no authored base prompt, no duplicate built-in usage prose, and
concise tool descriptions.

Skills, memory, custom system prompts, custom tool descriptions, and
required filesystem routing context remain intact. The legacy
base-prompt surface is removed rather than preserved as a default path.

## Changes

### Default prompt

- Remove the authored default base prompt and its obsolete public
surface.
- Suppress LangChain's default todo middleware prompt while leaving
deepagents-owned middleware prompt-free by default.
- Remove unused filesystem, subagent, async-subagent, and execution
prompt constants and exports.

### Durable tool guidance

- Keep large-result recovery guidance in `read_file` and `grep`
descriptions.
- Keep async task status freshness guidance in `check_async_task` and
`list_async_tasks` descriptions.
- Trim filesystem and task descriptions to their purpose and
load-bearing constraints.
- Build grep and execute descriptions from the configured filesystem
tool set so they do not recommend unavailable tools.

### Token impact

Offline (`o200k_base`, default-agent tool schemas):

| Tool | Before | After | Delta |
| --- | ---: | ---: | ---: |
| `task` | 1,664 | 389 | -77% |
| `read_file` | 728 | 494 | -32% |
| `grep` | 688 | 555 | -19% |
| `edit_file` | 273 | 257 | -6% |
| `glob` | 217 | 172 | -21% |
| `write_file` | 177 | 177 | — |
| `delete` | 146 | 146 | — |
| `ls` | 111 | 111 | — |
| **Total** | **4,005** | **2,302** | **-43%** |

For a default-agent `hello` turn, input tokens drop from 5,395 to 1,895
(-65%).

### Evaluation results

The lean prompt matched the baseline on correctness (0.81) and solve
rate (0.635 vs. 0.634). Unified evaluation macro and micro scores
improved from 0.413 to 0.437 and from 0.371 to 0.394, respectively. (see
more detailed results in

Hunter Lovell dd142fe4fc feat(deepagents): allow write_file to overwrite files (#674)
## Summary

`write_file` now creates missing files and replaces existing files
entirely, removing the previous create-only error path while preserving
write permissions and symlink protections.

## Changes

### deepagents filesystem backends

- Updated `FilesystemBackend`, `StateBackend`, `StoreBackend`,
`BaseSandbox`, and `node-vfs` write behavior to allow full-file
replacement on existing paths.
- Preserved path safety and symlink protections in filesystem-backed
writes.
- Removed the sandbox existence precheck so writes rely on the
upload/write transport.

### Tool prompts and examples

- Aligned the `write_file` tool description and schema text with the
Python SDK wording.
- Updated sandbox example prompts so `write_file` is described as
creating or fully replacing files.

### Tests and evals

- Updated backend, middleware, and shared sandbox standard tests that
previously expected an existing-file error.
- Added overwrite coverage for filesystem, sandbox, state, store,
middleware, node-vfs, and file-operation evals.

### Release

- Added a changeset for `deepagents` documenting the new overwrite
behavior.

Colin Francis 2ebb1785e4 fix(deepagents): return recoverable errors for invalid/denied filesystem tool paths instead of throwing (#693)
### Summary

Invalid (non-absolute, `..`, or `~`) or denied filesystem paths passed
by an agent cause the tool to throw which raises a `MiddlewareError` and
causes the whole agent run to crash.

This PR replaces `enforcePermission` which was re-validating the path
without a try/catch with `checkPermission` which returns the error to
the model as a normal tool result so the model can correct the path and
try again instead of crashing.

### Tests

Updated the three permission suites to assert an error result instead of
a throw and added a regression block for `~`/relative/`..` paths that
returns a recoverable error and never calls the backend.

Colin Francis 39a7049e4d fix(deepagents): backend adapter drops route prefixes (#691)
### Summary

`adaptBackendProtocol` rebuilds the backend into a v2 backend protocol
but drops its `routePrefixes`. Since `resolveBackend` runs every backend
through the adapter, a resolved `CompositeBackend` was no longer
detected as composite. That made the execute tool's guard fail at
invocation and disable the execute tool even when filesystem permissions
were correctly scoped to composite routes.

This PR fixes this by forwarding `routePrefixes` through
`adaptBackendProtocol` instead of dropping them.

### Tests

Added unit tests in backends/utils.test.ts to verify that
`routePrefixes` is forwarded through `adaptBackendProtocol` and
`adaptSandboxProtocol` and not added for non-composite backends.

Hunter Lovell cc26c41df2 fix(deepagents): merge custom middleware by name (#672)
## Summary

Adds middleware override behavior to replace default middleware by
`.name` instead of always being appended.

## Changes

- Add name-keyed middleware merging so custom middleware replaces
matching default middleware in-place and appends novel middleware after
the core stack.
- Apply default-slot middleware overrides consistently when constructing
main-agent and subagent middleware stacks, while preventing parent-only
middleware from propagating unless it matches a subagent default slot.
- Move harness tool exclusion into a private `_ToolExclusionMiddleware`
helper so excluded tools are stripped after tool-injecting middleware
has run.
- Add coverage for main-agent replacement, subagent/default override
propagation, parent-only middleware isolation, profile exclusions,
tool-exclusion ordering, and merge precedence.

Hunter Lovell f09bc61d7a feat(deepagents): implement delete across backends (#680)
## Summary

Implements the optional backend `delete` protocol across the built-in
backend implementations now that the delete protocol surface is
available. This keeps delete behavior backend-local and does not expose
a new filesystem tool to agents.

## Changes

### deepagents

- Implements `delete(filePath)` for filesystem, store, composite,
context hub, and sandbox backends.
- Uses backend-specific safety semantics: filesystem deletion goes
through existing path resolution and only unlinks files, store deletion
treats paths as exact keys, context hub deletion commits null entries,
and sandbox deletion uses shell-quoted `rm -f`.
- Adds tests covering successful deletion, missing paths, directory
rejection where applicable, composite route path restoration, store
wildcard literal behavior, and context hub cache updates/failure
handling.

### @langchain/node-vfs

- Implements `delete(filePath)` for the VFS backend.
- Adds tests for file deletion, missing paths, directory rejection, and
preserving non-target files.

Hunter Lovell 6ae9d1eab9 feat(deepagents): add filesystem tool allowlist (#671)
## Summary

Adds a `tools` allowlist option to `createFilesystemMiddleware` so
callers can restrict which built-in filesystem tools are exposed to the
model. The middleware now builds the filesystem system prompt from the
tools that are actually visible on the request, avoiding instructions
for tools that were filtered by the allowlist or backend capability
checks.

## Changes

- Adds a public `FsToolName` type and `tools` option to
`FilesystemMiddlewareOptions`.
- Filters filesystem middleware tools at construction time when an
explicit allowlist is provided, while preserving existing `execute`
backend capability filtering.
- Requires `read_file` in explicit allowlists because it is needed for
filesystem workflows and large-result recovery.
- Generates the filesystem tool prompt dynamically from visible
filesystem tools, and only appends execute-specific instructions when
`execute` is actually available.
- Adds unit and integration coverage for allowlist behavior, prompt
filtering, unsupported `execute`, and user-provided non-filesystem
tools.

Hunter Lovell eb18c70d8d feat(deepagents): add delete protocol support (#673)
## Summary

Adds protocol-level delete support for deepagents backends.

## Changes

### deepagents

- Adds `DeleteResult` to the backend protocol exports.
- Adds optional `delete(filePath)` support to v1 and v2 backend
protocols.
- Preserves optional delete implementations when adapting backends to
the v2 protocol.
- Implements `StateBackend.delete()` for zero-argument StateBackend
instances by sending `{ [filePath]: null }` through `__pregel_send`.
- Adds a changeset for the new backend protocol capability.

Colin Francis 7c8a770fac fix(deepagents): fast-glob follows directory symlink cycles leading to ELOOP crashes (#668)
### Summary

`fast-glob` follows symbolic links by default so the `glob`/`grep` tools
in `FilesystemBackend` and `LocalShellBackend` walked directory symlink
cycles recursively causing `ELOOP` crashes. and aborted the run over a
target repo.

This PR fixes by adding`followSymbolicLinks: false` to all four
`fast-glob` calls. Bonus: this keeps traversal inside the search root.

### Tests
Unit tests in `filesystem.test.ts` and `local-shell.test.ts` verifying
that a `sub/sub -> .` cycle now traverses cleanly without traversing
symlinks.

This is an upstream fix for:

Kowshik Padala 8efde93792 feat(deepagents): implement filesystem state management middleware with atomic update support and testing (#659)
## Problem
Addresses #658.

When using weaker or custom LLMs (e.g., smaller open-source models) in
`deepagents` and consumers like `openwiki`, the agent immediately
crashes with a schema validation error on the first filesystem tool
call:


This occurs because:
1. `ls` defines its directory argument as `path`, but `read_file`,
`write_file`, and `edit_file` expect `file_path`. Models often default
to `path` across all filesystem tools.
2. The description prompt examples in `fs.ts` and `skills.ts` show
`read_file(path, ...)`, instructing models to use the wrong parameter
name.

## Proposed Changes
This PR solves both prompt inconsistencies and schema validation
failures with a fully backward-compatible input normalization helper:

1. **Prompt Alignment**: Fixed references in `fs.ts` and `skills.ts` to
instruct the model to use `file_path` (aligned with the prompt fixes in
#644).
2. **Schema Input Normalization**: Added a `normalizeFilePathInput`
preprocessor helper to the `read_file`, `write_file`, and `edit_file`
Zod schemas using `z.preprocess`. This dynamically maps the `path` key
to `file_path` if the model still passes `path`.

## Verification & Tests
- Added unit tests in `fs.test.ts` to assert that:
- `path` parameter normalization maps correctly to `file_path` for
`read_file`, `write_file`, and `edit_file`.
  - All instruction examples contain only valid schema fields.
- Verified that `zod-to-json-schema` unwraps the `z.preprocess` layer
perfectly, preserving the original schema descriptions and definitions
sent to the LLM.
- Ran all filesystem tests successfully (`npx vitest run
src/middleware/fs.test.ts` passes).

Colin Francis 1a2b2df552 fix(deepagents): default unknown file extensions to text/plain (#656)
### Summary

`read_file` couldn't read many common text files and with Anthropic it
crashes the whole run. `getMimeType()` mapped any unrecognized extension
to `application/octet-stream`, which `isTextMimeType()` treats as
binary, so the file got base64-encoded into a document block.

This defaults unknown extensions to `text/plain` instead. Known binaries
(images, audio, video, PDF/PPT) stay explicitly mapped, so image and PDF
handling is unchanged. Files like `.properties`, `.scss`, `.tf`,
`.lock`, and extension-less files like `Dockerfile` now read as text.

  ### Tests
  
Flipped the unknown-extension unit test to expect `text/plain`.

Alexander Olsen d7ecab2d9f fix(deepagents): forward subagent results as text (#608)
## Summary

A deep agent that delegates to a subagent 400s when that subagent uses
an Anthropic server-side tool (web search, web fetch, code execution,
MCP). The subagent's final-message content blocks e.g.
server_tool_use/..._tool_result were forwarded verbatim as the task
ToolMessage content. On the parent agent's next request they serialize
into a tool_result, which Anthropic rejects:

`400 invalid_request_error
messages.N.content.0.tool_result.content.0: Input tag 'server_tool_use'
found using 'type'
does not match any of the expected tags:
'document','image','search_result','text','tool_reference'`

## Solution

Now matches the Python impl: forward only the subagent's text answer.
returnCommandWithStateUpdate now walks back to the last AIMessage with
non-empty text and uses that text (a string) as the ToolMessage content.

- Confirmed the Python deepagents impl is not affected (it forwards
.text); this aligns JS with Python.
- Reproduced the 400 across {web_search, code_execution, web_fetch} ×
{claude-haiku-4-5, claude-sonnet-4-6} on the latest published packages;
all green after the fix.

## Tests
- New: subagent server-tool blocks are filtered from forwarded content.
- New: walk-back uses the last non-empty AIMessage, skipping a trailing
empty message.
- Updated the #239/#245 tests to assert the (now string) ToolMessage
content.
- No regressions in subagent-related tests in the evals suite

Christian Bromann 7c4a11eacc fix(deepagents): use langchain run.subagents instead of bespoke transformer (#598)
## Summary
- Remove deepagents' bespoke `createSubagentTransformer` (~460 lines)
and wire `createDeepAgent` to langchain's native `run.subagents`
projection from `createAgent` (langchain#37739).
- Slim `stream.ts` to type-only exports: re-export `SubagentRunStream`
from langchain and keep `DeepAgentRunStream` as a compile-time narrowing
over declared subagent specs.
- Update streaming tests for `sub.cause` (replacing `taskInput`), add
single-subagent `sub.messages` coverage, and document parallel-subagent
streaming behavior.
- Pin `langchain@1.4.6-dev-1781497519109` and `@langchain/langgraph` /
`@langchain/langgraph-checkpoint` to `d2312cf` dev builds (root
`pnpm.overrides`) for end-to-end verification until published releases
are available.
- Clarify `streamTransformers` docs: custom transformers surface on
`run.extensions`; built-in streams like `run.subagents` and
`run.toolCalls` are separate.

### Summary

This PR adds a default task primitive to the code interpreter that
allows the agent to natively write code to programmatically dispatch
subagents. The task primitive supports passing response schemas for
dynamic structured output that helps with more complex orchestration
patterns.

This PR also removes the swarm task tool in favor of the task primitive.

- chore(deps): bump uuid to 14.0.0 and keep checkpoint ID ordering
stable</p>
<p>Bump <code>uuid</code> from 10.x/13.x to 14.0.0 across packages.
Starting with uuid 11, <code>v6({ clockseq })</code> no longer advances
the sub-millisecond time counter when an explicit <code>clockseq</code>
is passed, so checkpoint IDs created within the same millisecond were
ordered only by <code>clockseq</code>. Since checkpoint IDs are sorted
lexicographically, this broke ordering — most visibly for the negative
<code>clockseq</code> used by the first (&quot;input&quot;) checkpoint,
which sorted as the newest.</p>
<p><code>uuid6()</code> now maintains its own monotonic <code>(msecs,
nsecs)</code> clock (mirroring uuid 10's internal v1 behavior) so the
time component is always strictly increasing and checkpoint ordering no
longer depends on the <code>clockseq</code> value.
<code>emptyCheckpoint()</code> also uses a non-negative
<code>clockseq</code>.</p>

- chore(deps): bump uuid to 14.0.0 and keep checkpoint ID ordering
stable</p>
<p>Bump <code>uuid</code> from 10.x/13.x to 14.0.0 across packages.
Starting with uuid 11, <code>v6({ clockseq })</code> no longer advances
the sub-millisecond time counter when an explicit <code>clockseq</code>
is passed, so checkpoint IDs created within the same millisecond were
ordered only by <code>clockseq</code>. Since checkpoint IDs are sorted
lexicographically, this broke ordering — most visibly for the negative
<code>clockseq</code> used by the first (&quot;input&quot;) checkpoint,
which sorted as the newest.</p>
<p><code>uuid6()</code> now maintains its own monotonic <code>(msecs,
nsecs)</code> clock (mirroring uuid 10's internal v1 behavior) so the
time component is always strictly increasing and checkpoint ordering no
longer depends on the <code>clockseq</code> value.
<code>emptyCheckpoint()</code> also uses a non-negative
<code>clockseq</code>.</p>

Alexei Vedernikov e3d4b5367b feat(deepagents): support direct skill paths as sources in createSkillsMiddleware (#242)
## Description

Previously, sources had to be parent directories (e.g. `/skills/`) whose
subdirectories each contained a SKILL.md. Passing a direct skill path
(e.g. `/skills/my-skill/`) had no effect because `listSkillsFromBackend`
scanned for subdirectories inside the source, found none, and returned
an empty list.

## Real case

The motivating scenario is when a curated list of skills organised as
individual directories under a shared directory. Each skill has a clear
responsibility, and different skills are intentionally assigned to the
orchestrator agent vs. subagents:

```typescript
// Desired: pass individual skill paths — one per capability
const SHARED_SKILLS = ['/skills/web-research/'];

const ORCHESTRATOR_SKILLS = [
  '/skills/requirement-completeness-validator/',
  '/skills/diff-risk-analyzer/',
];

createDeepAgent({
  skills: [...SHARED_SKILLS, ...ORCHESTRATOR_SKILLS],
  subagents: subagentsConfig.map(agentConfig => ({
    skills: [
      ...SHARED_SKILLS,
      ...agentConfig.skills,
    ]
  }))
});
```

The workaround would be to create nested directories like this:
```
skills/
  web-research/
    web-research/
      SKILL.md
  equirement-completeness-validator/
    equirement-completeness-validator/
      SKILL.md
  ...and so on
```

## What's done

Detection is done by inspecting the lsInfo() result of the source
directory: if a SKILL.md file appears directly in the listing, the
source itself is treated as the skill directory. Otherwise the existing
parent-directory scan runs unchanged.

The two modes can be freely mixed in the sources array:
```ts
sources: [
  '/skills/',               // parent dir: all subdirs with SKILL.md
  '/skills/my-skill/',      // direct path: SKILL.md at its root
 ]
 ```

Hunter Lovell 27ebdc3fea chore(deepagents): clarify LocalShellBackend virtualMode behavior (#577)
## Summary

Fixes #544.

Clarifies `LocalShellBackend` path semantics without introducing a
breaking default change. This keeps legacy behavior intact while making
the bounded-workspace setup explicit in docs and examples.

## Changes

### deepagents (`LocalShellBackend`)

- Clarified `LocalShellBackendOptions` docs to explicitly note that
`rootDir` does not bound filesystem paths when `virtualMode` is `false`.
- Updated `LocalShellBackend` examples to use `virtualMode: true` when
bounded path semantics are intended.
- Added unit coverage to assert legacy behavior is preserved: with
`virtualMode: false`, absolute writes can resolve outside `rootDir`.

Anton Nak 18557db7bb fix(deepagents): gate cache_control writes on per-call request.model (#551)
Fixes #550.

## Problem

`createCacheBreakpointMiddleware` and `createMemoryMiddleware` write
Anthropic-specific `cache_control: { type: "ephemeral" }` markers into
the request payload. Both gate the write at **agent-creation time** in
`createDeepAgent` (whether the *primary* model is Anthropic). When
`modelFallbackMiddleware` swaps `request.model` to a non-Anthropic
provider at request time, the markers leak through and the fallback
provider rejects the request:

```
400 Unknown parameter: 'messages[0].content[N].cache_control'
```

Full root-cause writeup, production trace, and reproduction in #550.

## Fix

Move the model classification from boot-time to **per-call**, using the
existing `isAnthropicModel` helper (`src/utils.ts:9`).

- **`src/middleware/cache.ts`** — bail at the top of `wrapModelCall`
when `request.model` isn't Anthropic.
- **`src/middleware/memory.ts`** — AND the existing `addCacheControl`
flag with the same per-call check. `addCacheControl` keeps its current
public meaning (opt-in switch); the per-call gate is an additional
safety net.
- **`src/agent.ts`** — left untouched. The boot-time install gate stays
(small perf win when primary is non-Anthropic — middleware isn't
installed at all). The new per-call check handles the fallback case
where the middleware *is* installed but the model has been swapped.

## Tests

Each middleware's `.test.ts` got a `per-call provider gating` block.
They build a request with a `ChatAnthropic`-shaped stub vs a
`ChatOpenAI`-shaped stub on `request.model`, run `wrapModelCall`, and
assert `cache_control` is/isn't written. Also covers `ConfigurableModel`
with `modelProvider: "anthropic"` and the string forms
(`"anthropic:claude-..."`, `"openai:gpt-5"`).

Existing fixtures that didn't set `request.model` now pass a
`ChatAnthropic` stub so they keep exercising the write path — they were
previously relying on the unconditional behavior. No behavioral
assertions changed; only the fixture got more explicit.

31/31 tests pass on `libs/deepagents` (`cache.test.ts` +
`memory.test.ts`).

## Compatibility

- **No public API change.** `addCacheControl?: boolean` on
`MemoryMiddlewareOptions` keeps its existing semantics.
- **Anthropic-primary happy path unchanged** — same writes, same cache
hits.
- **Per-call cost:** one `getName()` / string check inside
`wrapModelCall`. Sub-microsecond.
- **Failure mode improvement:** users running `createDeepAgent` with an
Anthropic primary + non-Anthropic fallback no longer get a 400 from the
fallback provider on swap.

## Changeset

`patch` bump on `deepagents`.

## Out of scope

`request.modelSettings.cache_control` (written by LangChain core's
`anthropicPromptCachingMiddleware`) can also leak across the swap.
Mentioned in #550 for tracking — that's a LangChain-side fix, not
deepagents.

Aman Pandey 1ca6dc92fd fix(deepagents): return application/octet-stream for unknown MIME types (#541)
Fixes #542.

`getMimeType()` falls back to `"text/plain"` for any extension not in
the `MIME_TYPES` lookup table. Since `isTextMimeType("text/plain")`
returns `true`, this means binary files (.zip, .exe, .wasm, .sqlite,
.pyc, .class, .jar, etc.) get treated as text everywhere downstream —
grep searches through them and returns garbage, read_file splits their
content on newlines and paginates it, and StateBackend can silently
corrupt binary data stored via createFileData().

The fix is straightforward: change the default to
`"application/octet-stream"`, which is what unknown binary data should
be. `isTextMimeType()` already returns `false` for it, so binary files
stop getting mangled.

To avoid breaking existing behavior for actual text files that were
previously relying on the fallback (like .txt, .ts, .py, .json, .js —
none of which had explicit entries), this also adds those to the
MIME_TYPES map directly. Covers ~67 common text/code extensions.

All 386 backend tests pass (10 files). The updated test expectations in
utils.test.ts verify both sides: known text extensions still resolve
correctly, and unknown/binary extensions now get
`application/octet-stream` instead of being misidentified as text.

Hunter Lovell 84f3c0c2f1 fix(deepagents): add browser and node entrypoints (#574)
## Summary

Fixes #292, #543

This updates `deepagents` packaging to split environment-specific
exports and avoid browser build failures caused by Node-only imports in
the default bundle. Browser consumers now have an explicit
`deepagents/browser` entrypoint, while Node consumers can keep using
`deepagents` (or optionally `deepagents/node`) for the full runtime API.

## Changes

### `deepagents` package exports and entrypoints

- Added `src/browser.ts` as a browser-safe public barrel that excludes
Node-only APIs.
- Added `src/node.ts` as an explicit Node entrypoint that re-exports the
full API.
- Updated `package.json` exports to:
  - route the root `browser` condition to `./dist/browser.js`
  - expose `./browser` and `./node` subpath exports (ESM + CJS + types).
- Updated `tsdown` config to build `index`, `browser`, and `node`
outputs.

### Runtime import graph hardening

- Updated `createDeepAgent` to import `StateBackend` directly from
`backends/state` so it no longer pulls in the full Node-oriented
backends barrel.
- Updated `types.ts` to import `AnyBackendProtocol` from
`backends/protocol` instead of `backends/index`.
- Removed named Node builtin path imports from `backends/utils.ts` by
replacing `path.basename`/`path.extname` with local helpers.

### Documentation and release notes

- Added a README section documenting import guidance: browser apps
should use `deepagents/browser`, and Node apps can continue to use
`deepagents`.
- Added a patch changeset for `deepagents` describing the entrypoint and
packaging fix.

Hunter Lovell 03df237385 fix(deepagents): scope composite route search fanout by path (#572)
## Summary

Fixes #241.

This updates `CompositeBackend` search routing so scoped `grep`/`glob`
requests only fan out to routed backends mounted under the requested
path. Previously, non-route paths (for example `/workspace`) still
queried all routes, which could trigger unrelated backend errors.

## Changes

### `libs/deepagents/src/backends/composite.ts`

- Added route/path helper predicates to distinguish:
  - when a search path is inside a route,
  - when a route is a descendant of the requested search path.
- Updated `grep` fallback behavior to query the default backend plus
only descendant routes (instead of unconditional all-route fanout).
- Updated `glob` fallback behavior to use the same descendant-route
filtering.
- Normalized `grep` path handling to accept `null` and treat it as root
(`/`).
- Reused the same route-matching helper in `ls` for consistent prefix
matching semantics.

### `libs/deepagents/src/backends/composite.test.ts`

- Added regression test to ensure `grep("...", "/workspace")` does not
call unrelated routes (for example `/skills/`) while still searching
relevant descendant routes.
- Added regression test for equivalent `glob` behavior.

accompanying tests. Example:

```
const stateSchema = new StateSchema({
  foo: z.string().default("foo"),
});
const agent = createDeepAgent({ model, stateSchema });
// agent.graph.channels includes attribute foo
```

### Callouts
**Opted against compile/runtime check for stateSchema keys**
There is a strong argument here to add a compile-time or runtime check
to ensure uniqueness of `stateSchema` keys to guard against the
first-writer-wins behavior of channel merging. [There is already a
runtime tool name
check](https://github.com/langchain-ai/deepagentsjs/blob/c524561ad0c4b13075b0d0999236f09bf5f6cb89/libs/deepagents/src/agent.ts#L185).
However the topic of how channel merging is handled, I think, deserves a
fast follow to ensure that consumers of this API are properly educated
(rather than just throwing in this key concept into a single docstring).

Hunter Lovell 04cc3fc260 fix(deepagents): propagate subagent lc_agent_name for delegated tasks (#566)
## Summary

Fixes #206.

This updates deepagents subagent delegation so tool executions can
reliably identify the active subagent via
`config.metadata.lc_agent_name` instead of inheriting the parent agent
name. It also adds focused regression tests that validate both compiled
subagents and standard subagent specs follow the same metadata behavior.

## Changes

### `libs/deepagents` subagent metadata propagation

- Updated `createTaskTool` subagent invocation config to explicitly set:
  - `metadata.lc_agent_name = subagent_type`
- existing `configurable.ls_agent_type = "subagent"` behavior remains
unchanged
- Added new regression coverage in `subagent.test.ts`:
  - compiled subagent (`runnable`) path
  - standard subagent spec (`systemPrompt/tools/model`) path
- Tests assert tool-time metadata receives the delegated subagent name
(`worker`), preventing parent-name leakage.

### `libs/deepagents` dependency range update

- Bumped `langsmith` peer dependency range in
`libs/deepagents/package.json` from `>=0.6.0 <1.0.0` to `^0.7.1`.
- Updated `pnpm-lock.yaml` accordingly.

Christian Bromann 9c666ba44a fix(deepagents): handle non-string content blocks in tool result sizechecking (#288)
Fixes #277

The tool result eviction logic in `processToolMessage` only checked
`content` when it was a plain string (`typeof msg.content ===
"string"`), which meant array-based content blocks (e.g. `[{ type:
"text", text: "..." }]`) bypassed the size limit entirely and were sent
back to the agent untruncated.

The fix uses the existing `BaseMessage.text` getter from
`@langchain/core`, which already handles both content formats:
- **String content**: returned as-is
- **Array content blocks**: joins all blocks with `type === "text"` into
a single string

This avoids introducing any new utility functions — the upstream API
already solves this.

## Changes

- Updated `processToolMessage()` in `fs.ts` to use `msg.text` instead of
directly checking `msg.content`
- Added 2 unit tests covering array-based content block eviction (large
and small)

Colin Francis bfb6eecdfe feat(quickjs): add swarm task tool (#500)
### Summary

Adds the swarm task tool to @langchain/quickjs and fixes skill module
loading for the agentskills.io spec, enabling parallel subagent dispatch
from inside the QuickJS code interpreter.

Swarm task tool (tools/swarm-task.ts) is a PTC-only tool that bridges
the code interpreter to the host runtime for subagent dispatch. It
supports two modes:
1. Direct model calls with structured output (invoke mode) for
classification/extraction tasks
2. Full agentic loops with tools (agent mode) for multi-step reasoning.
It handles schema normalization, model variant caching with TTL-based
sweeping, and structured output binding.

Spec-compliant entrypoint resolution — loadSkill() now resolves the
entrypoint from metadata.entrypoint (the agentskills.io extension point)
first, falling back to the legacy top-level module field. This lets
skills use spec-compliant frontmatter without a top-level module key.

Subdirectory entrypoint support — the QuickJS module normalizer now uses
the entrypoint's directory (not the skill root) when resolving relative
imports from a bare specifier. This fixes import { ... } from
"./sibling.js" when the entrypoint lives in a subdirectory like
scripts/index.ts.

Supporting changes include wiring skills metadata through the middleware
and session layers, extending the transform pipeline to strip import
type/export type declarations, adding requiredPtcTools validation, and
session improvements (extractToolText, stripLineNumbers, __sessionId__).

The swarm skill itself (table management, batching, filtering,
interpolation) is distributed separately and not included here.

### Tests
- 41 tests for the swarm task tool covering both dispatch modes, schema
normalization, variant caching and TTL sweeping, error handling, and
edge cases around model binding
- 3 new tests for entrypoint resolution (metadata.entrypoint preferred
over module, subdirectory relative imports)

Vishnu Suresh f0880899ea feat(deepagents): add ContextHubBackend backend (#533)
This ports Python deepagents PR #3338 behavior into the JS SDK by
introducing a new first-class backend: `ContextHubBackend`.

Why:
- Context Hub repo persistence is now available as an SDK backend in JS,
matching the Python backend architecture.
- This gives JS users a canonical LangSmith Hub-backed file backend with
the same operational semantics (lazy pull, commit chaining, cache
invalidation, batch upload behavior).

What changed:
- Added `ContextHubBackend` in
`libs/deepagents/src/backends/context-hub.ts`.
- Exported it from backend and root package exports.
- Added parity-focused unit tests in `context-hub.test.ts`.
- Added integration contract tests in `context-hub.int.test.ts` (gated
by `LANGSMITH_API_KEY`).
- Updated `deepagents` peer dependency on `langsmith` from `>=0.5.20` to
`>=0.6.0` to rely on Hub directory APIs (`pullAgent` / `pushAgent`).
- Added a changeset for release notes.

Behavior highlights:
- Missing repo on pull is treated as empty and lazily created on first
write.
- In-memory file cache with linked-entry tracking (`getLinkedEntries`).
- Commit hash tracking with optimistic `parentCommit` chaining.
- Cache invalidation on mutating Hub failures.
- `uploadFiles` commits all valid UTF-8 files in a single batch commit
and returns per-file success/error.

Validation run:
- `pnpm install`
- `pnpm exec oxfmt --write ...` (touched files)
- `pnpm --filter deepagents exec oxlint ...` (touched files)
- `pnpm --filter deepagents exec vitest run
src/backends/context-hub.test.ts` (33 passed)
- `pnpm --filter deepagents exec vitest run --mode int
src/backends/context-hub.int.test.ts` (skipped without
`LANGSMITH_API_KEY`)

Colin Francis 7c33a8695f feat(deepagents): implement harness profiles (#526)
### Summary

Introduces harness profiles which is a way to declaratively control how
agents behave at runtime without changing which model is used. A profile
can override the system prompt, hide tools, add or remove middleware,
and configure the general-purpose subagent. Profiles are registered by
provider or model key ("anthropic", "openai:gpt-5.4") and looked up
automatically when `createDeepAgent` is called.

The system ships with built-in profiles for Anthropic Opus 4.7, Sonnet
4.6, Haiku 4.5, and OpenAI Codex that include vendor-recommended
prompting guidance. Users can register their own profiles on top and
registrations merge additively so provider-wide defaults compose with
model-specific overrides.

Profiles are plain frozen objects with Zod schemas for parsing from
JSON/YAML config files, including prototype-pollution protection for
untrusted input.

### Tests

Unit tests cover key validation, profile construction and freezing,
serialization round-trips, poison-key rejection, merge semantics across
all field types, registry lookup with provider fallback, and prompt
overlay behavior. Built-in profiles are tested for correct registration
and expected content.

Also verified end-to-end via a standalone script against LangSmith and
confirmed the custom suffix appears in the system prompt and excluded
tools are absent from the model call.
  
### Usage Example
```ts
import { HumanMessage } from "@langchain/core/messages";
import { createDeepAgent, registerHarnessProfile } from "deepagents";

registerHarnessProfile("anthropic:claude-sonnet-4-6", {
  systemPromptSuffix: "Always respond in exactly one sentence.",
  excludedTools: ["grep"],
  generalPurposeSubagent: {
    description: "A customized GP subagent via harness profile.",
  },
});

const agent = createDeepAgent({
  model: "anthropic:claude-sonnet-4-6",
});

const result = await agent.invoke({
  messages: [new HumanMessage("What is the capital of France?")],
});

const lastMessage = result.messages[result.messages.length - 1];
console.log("Response:", lastMessage.content);
```

Hunter Lovell 8a6de8e7ee fix(deepagents): align LangSmith sandbox create options with SDK (#528)
## Summary

This fixes a CI-breaking type mismatch in the LangSmith sandbox backend
introduced by the snapshot lifecycle update. `LangSmithSandbox.create()`
was using a `snapshotId` flow that did not match the current `langsmith`
SDK typings, which surfaced as unhandled Vitest typecheck errors in CI.

Ramon Nogueira f164f992e0 feat(deepagents): add snapshot/start/stop lifecycle to LangSmithSandbox (#479)
## Summary

Expose the new LangSmith sandbox snapshot and lifecycle APIs (landed in
`langsmith@0.5.20`) through the `LangSmithSandbox` wrapper.

- New methods on `LangSmithSandbox`: `start()`, `stop()`,
`captureSnapshot()`
- `LangSmithSandbox.create()` now accepts `snapshotId` (preferred) or
`templateName` (deprecated); throws if neither is provided
- Re-export upstream types as `LangSmithSnapshot`,
`LangSmithCaptureSnapshotOptions`, `LangSmithStartSandboxOptions`
- Bump `langsmith` peer dep to `>=0.5.20`
- Update the example to boot from `LANGSMITH_SANDBOX_SNAPSHOT_ID`

## Test plan

- [x] Unit tests: added coverage for `start()`, `stop()`,
`captureSnapshot()`; 41/41 pass
- [x] Type-check clean
- [x] Dev smoke test against `dev.api.smith.langchain.com` — create from
snapshot, execute, stop, start, execute after restart all working

Colin Francis 8fd575f06c feat(deepagents): implement functional skills for quickjs middleware (#496)
### Summary

Adds functional skill modules to the QuickJS REPL. Skills can now ship
JS/TS entrypoints via a module: frontmatter key on SKILL.md, which the
model dynamically imports at eval time with await
import("@/skills/<name>").

When skillsBackend is passed to createQuickJSMiddleware, the middleware
reads skillsMetadata from the current task state before each eval, scans
the source for skill references, and pushes the metadata + backend into
the session. The session wires a QuickJS module loader that lazily
fetches skill files from the backend, strips TypeScript syntax, and
caches the result for the lifetime of the session. Skills that are
referenced but not available on the agent short-circuit with a clear
error before evaluation starts.

On the deepagents side, SkillMetadata gains an optional module field
(validated and normalized from frontmatter), and formatSkillsList now
advertises importable skills in the system prompt with an await
import(...) hint.

```ts
const backend = new FilesystemBackend({ rootDir: "/project", virtualMode: true });

const agent = createDeepAgent({
  model: "claude-sonnet-4-6",
  backend,
  skills: ["/skills/"],
  middleware: [
    createQuickJSMiddleware({ skillsBackend: backend }),
  ],
});
```

### Tests

- Unit tests cover module path validation, TS syntax stripping, skill
loading (single/multi-file, error cases, bundle size cap), skill
reference scanning, module loader resolution and caching, and system
prompt formatting
- Ran an E2E eval that exercised the full pipeline from SKILL.md parse
through dynamic import and function call in the REPL, with a LangSmith
trace

Colin Francis 998d772a07 feat(quickjs): remove built-in VFS globals, add PTC instance injection and StateBackend read-your-writes (#486)
### Summary
- Removed built-in readFile/writeFile globals from the QuickJS REPL.
File I/O is now exclusively through PTC tools, keeping the REPL a pure
JS sandbox with no implicit side effects
- ptc now accepts StructuredToolInterface instances directly alongside
tool name strings. Custom tools can be injected into the REPL without
being registered on the agent
- StateBackend now provides read-your-writes semantics within a single
js_eval superstep by reading via __pregel_read with fresh=true. Pregel
already tracks pending sends in task.writes; asking for a fresh read
applies them through the reducer, removing the need for a manual write
buffer
- Removed ptc: boolean shorthand from QuickJSMiddlewareOptions; use the
array or object forms instead

### Tests
- Added 12 unit tests to state.test.ts covering write-then-read, chained
edits, ls/grep/glob/readRaw visibility, upload/download, duplicate write
error, edit-nonexistent, and superstep boundary behavior
(commitSends/clearPending)
- Expanded middleware.test.ts with PTC instance injection coverage
- Verified end-to-end with createDeepAgent + createQuickJSMiddleware
across 7 scenarios (write-read, write-edit-read, write-ls, write-grep,
write-glob, cross-eval, upload-download); traces confirmed in LangSmith

Colin Francis 43cd121133 feat(deepagents): implement file system permissions for fs middleware tools (#492)
### Summary

- Adds a FilesystemPermission class and a permissions parameter to
createDeepAgent and SubAgent that controls which filesystem operations
each agent is allowed to perform
- Rules are evaluated first-match-wins with a permissive default; mode:
"deny" blocks the operation before any backend call
- Permissions are closed over at tool-creation time — no runtime config
threading, no ToolPolicy in langchain-core
- ls, glob, and grep enforce permissions in two passes: the base path
check throws early; results are post-filtered to strip entries the
caller can't read
- Subagents receive the parent agent's permissions by default; setting
permissions on a SubAgent is a full replacement, not a merge
- FilesystemPermission, FilesystemPermissionOptions,
FilesystemOperation, and PermissionMode are exported from the top-level
package entry point

### Tests

- permissions/types.test.ts — FilesystemPermission construction,
validation (rejects relative paths, .., ~), defaults
- permissions/enforce.test.ts — validatePath, globMatch (wildcards,
brace expansion, dotfiles), decidePathAccess (first-match-wins,
operation mismatch, multiple ops/paths)
- middleware/fs.permissions.test.ts — each fs tool (read, write, edit,
ls, glob, grep) with allow/deny rules and mock backends; verifies
backend is never called on a denied path; verifies execute is unaffected
- permissions/agent.permissions.test.ts —
CreateDeepAgentParams.permissions type and default; wiring to
createFilesystemMiddleware
- middleware/subagents.permissions.test.ts — SubAgent.permissions type;
?? resolution (inherit vs override vs own deny);
createFilesystemMiddleware behavior for each resolved-permissions case

Hunter Lovell 2442d7d080 fix(deepagents): align summarization with active request model (#465)
## Summary

Fixes #398

Align deepagents summarization with the active request-time model path
instead of relying on a separate middleware-specific model resolution
path. This keeps summarization behavior consistent with the main agent
model selection flow and avoids divergence in provider/model handling
during middleware execution. The update also simplifies runtime behavior
by removing unnecessary explicit config threading for summary calls.

## Changes

### `deepagents` middleware/model routing

- Updated summarization middleware to prefer `request.model` as the
resolved model used for profile-derived limits and summary generation.
- Kept fallback model resolution support for cases where a request model
is not present.
- Removed explicit runtime config plumb-through in summary invocation,
relying on LangChain runnable context propagation.

### `deepagents` agent wiring

- Updated `createDeepAgent` built-in and subagent middleware wiring to
construct summarization middleware without explicitly passing a separate
model option, so summarization follows the active request model path.

### `deepagents` tests

- Added/updated summarization tests to cover request-model-based
summarization behavior and ensure middleware behavior remains stable
with the new routing path.
- Simplified test request construction to keep request-model assumptions
explicit.
