1819c73d10 docs(docs): update Docker to ClickHouse 25.7 with vector_similarity support (#32659)
- **Description:** Updated Docker command to use ClickHouse 25.7 (has
`vector_similarity` index support). Added `CLICKHOUSE_SKIP_USER_SETUP=1`
env param to [bypass default user
setup](https://clickhouse.com/docs/install/docker#managing-default-user)
and allow external network access. There was also a bug where if you try
to access results using `similarity_search_with_relevance_scores`, they
need to unpacked first.

- **Issue:** Fixes #32094 if someone following tutorial with default
Clickhouse configurations.

8d0fb2d04b fix(anthropic): correct input_token count for streaming (#32591)
* Create usage metadata on
[`message_delta`](https://docs.anthropic.com/en/docs/build-with-claude/streaming#event-types)
instead of at the beginning. Consequently, token counts are not included
during streaming but instead at the end. This allows for accurate
reporting of server-side tool usage (important for billing)
* Add some clarifying comments
* Fix some outstanding Pylance warnings
* Remove unnecessary `text` popping in thinking blocks
* Also now correctly reports `input_cache_read`/`input_cache_creation`

8042b04da6 fix(anthropic): clean up null file_id fields in citations during message formatting (#32592)
When citations are returned from streaming, they include a `file_id:
null` field in their `content_block_location` structure.

When these citations are passed back to the API in subsequent messages,
the API rejects them with "Extra inputs are not permitted" for the
`file_id` field.

03138f41a0 feat(text-splitters): add optional custom header pattern support (#31887)
## Description

This PR adds support for custom header patterns in
`MarkdownHeaderTextSplitter`, allowing users to define non-standard
Markdown header formats (like `**Header**`) and specify their hierarchy
levels.

**Issue:** Fixes #22738

**Dependencies:** None - this change has no new dependencies

**Key Changes:**
- Added optional `custom_header_patterns` parameter to support
non-standard header formats
- Enable splitting on patterns like `**Header**` and `***Header***`
- Maintain full backward compatibility with existing usage
- Added comprehensive tests for custom and mixed header scenarios

## Example Usage

```python
from langchain_text_splitters import MarkdownHeaderTextSplitter

headers_to_split_on = [
    ("**", "Chapter"),
    ("***", "Section"),
]

custom_header_patterns = {
    "**": 1,   # Level 1 headers
    "***": 2,  # Level 2 headers
}

splitter = MarkdownHeaderTextSplitter(
    headers_to_split_on=headers_to_split_on,
    custom_header_patterns=custom_header_patterns,
)

# Now **Chapter 1** is treated as a level 1 header
# And ***Section 1.1*** is treated as a level 2 header
```

## Testing

-  Added unit tests for custom header patterns
-  Added tests for mixed standard and custom headers
-  All existing tests pass (backward compatibility maintained)
-  Linting and formatting checks pass

---

The implementation provides a flexible solution while maintaining the
simplicity of the existing API. Users can continue using the splitter
exactly as before, with the new functionality being entirely opt-in
through the `custom_header_patterns` parameter.

d3d23e2372 fix(anthropic): streaming token counting to defer input tokens until completion (#32518)
Supersedes #32461

Fixed incorrect input token reporting during streaming when tools are
used. Previously, input tokens were counted at `message_start` before
tool execution, leading to inaccurate counts. Now input tokens are
properly deferred until `message_delta` (completion), aligning with
Anthropic's billing model and SDK expectations.

**Before Fix:**
- Streaming with tools: Input tokens = 0 
- Non-streaming with tools: Input tokens = 472 

**After Fix:**
- Streaming with tools: Input tokens = 472 
- Non-streaming with tools: Input tokens = 472 

Aligns with Anthropic's SDK expectations. The SDK handles input token
updates in `message_delta` events:

```python
# https://github.com/anthropics/anthropic-sdk-python/blob/main/src/anthropic/lib/streaming/_messages.py
if event.usage.input_tokens is not None:
      current_snapshot.usage.input_tokens = event.usage.input_tokens
```

fe740a9397 fix(docs): chatbot.ipynb trimming regression (#32561)
Supersedes #32544

Changes to the `trimmer` behavior resulted in the call `"What math
problem was asked?"` to no longer see the relevant query due to the
number of the queries' tokens. Adjusted to not trigger trimming the
relevant part of the message history. Also, add print to the trimmer to
increase observability on what is leaving the context window.

Add note to trimming tut & format links as inline

a0331285d7 fix(core): Support no-args tools by defaulting args to empty dict (#32530)
Supersedes #32408

Description:  
This PR ensures that tool calls without explicitly provided `args` will
default to an empty dictionary (`{}`), allowing tools with no parameters
(e.g. `def foo() -> str`) to be registered and invoked without
validation errors. This change improves compatibility with agent
frameworks that may omit the `args` field when generating tool calls.

Issue:  
See
[langgraph#5722](https://github.com/langchain-ai/langgraph/issues/5722)
–
LangGraph currently emits tool calls without `args`, which leads to
validation errors
when tools with no parameters are invoked. This PR ensures compatibility
by defaulting
`args` to `{}` when missing.

Dependencies:  
None

be83ce74a7 feat(anthropic): support cache_control as a kwarg (#31523)
```python
from langchain_anthropic import ChatAnthropic

llm = ChatAnthropic(model="claude-3-5-haiku-latest")
caching_llm = llm.bind(cache_control={"type": "ephemeral"})

caching_llm.invoke(
    [
        HumanMessage("..."),
        AIMessage("..."),
        HumanMessage("..."),  # <-- final message / content block gets cache annotation
    ]
)
```
Potentially useful given's Anthropic's [incremental
caching](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#continuing-a-multi-turn-conversation)
capabilities:
> During each turn, we mark the final block of the final message with
cache_control so the conversation can be incrementally cached. The
system will automatically lookup and use the longest previously cached
prefix for follow-up messages.

# Description

This PR updates the docs for the
[langchain-anchorbrowser](https://pypi.org/project/langchain-anchorbrowser/)
package. It adds a few tools

[Anchor Browser](https://anchorbrowser.io/?utm=langchain) is the
platform for AI Agentic browser automation, which solves the challenge
of automating workflows for web applications that lack APIs or have
limited API coverage. It simplifies the creation, deployment, and
management of browser-based automations, transforming complex web
interactions into simple API endpoints.

11a54b1f1a docs: clarify SystemMessage usage in LangGraph agent notebook (#32320) (#32346)
Closes #32320

This PR updates the `langgraph_agentic_rag.ipynb` notebook to clarify
that LangGraph does not automatically prepend a `SystemMessage`. A
markdown note and an inline Python comment have been added to guide
users to explicitly include a `SystemMessage` when needed.

This improves documentation for developers working with LangGraph-based
agents and avoids confusion about system-level behavior not being
applied.

<details>
<summary>Release notes</summary>
<p><em>Sourced from <a

<blockquote>
<h2>v5.0.0</h2>
<h2>What's Changed</h2>
<ul>
<li>Update README.md by <a
href="https://github.com/nebuk89"><code>@​nebuk89</code></a> in <a

</ul>
<h2>v5.0.0</h2>
<h3>🚨 Breaking Change</h3>
<p>This release fixes an inconsistency in path behavior for single
artifact downloads by ID. <strong>If you're downloading single artifacts
by ID, the output path may change.</strong></p>
<h4>What Changed</h4>
<p>Previously, <strong>single artifact downloads</strong> behaved
differently depending on how you specified the artifact:</p>
<ul>
<li><strong>By name</strong>: <code>name: my-artifact</code> → extracted
to <code>path/</code> (direct)</li>
<li><strong>By ID</strong>: <code>artifact-ids: 12345</code> → extracted
to <code>path/my-artifact/</code> (nested)</li>
</ul>
<p>Now both methods are consistent:</p>
<ul>
<li><strong>By name</strong>: <code>name: my-artifact</code> → extracted
to <code>path/</code> (unchanged)</li>
<li><strong>By ID</strong>: <code>artifact-ids: 12345</code> → extracted
to <code>path/</code> (fixed - now direct)</li>
</ul>
<h4>Migration Guide</h4>
<h5> No Action Needed If:</h5>
<ul>
<li>You download artifacts by <strong>name</strong></li>
<li>You download <strong>multiple</strong> artifacts by ID</li>
<li>You already use <code>merge-multiple: true</code> as a
workaround</li>
</ul>
<h5>⚠️ Action Required If:</h5>
<p>You download <strong>single artifacts by ID</strong> and your
workflows expect the nested directory structure.</p>
<p><strong>Before v5 (nested structure):</strong></p>
<pre lang="yaml"><code>- uses: actions/download-artifact@v4
  with:
    artifact-ids: 12345
    path: dist
# Files were in: dist/my-artifact/
</code></pre>
<blockquote>
<p>Where <code>my-artifact</code> is the name of the artifact you
previously uploaded</p>
</blockquote>
<p><strong>To maintain old behavior (if needed):</strong></p>
<pre lang="yaml"><code>&lt;/tr&gt;&lt;/table&gt; 
</code></pre>

130b7e6170 docs(docs): add missing name to AIMessage in example (#32482)
**Description:**

In the `docs/docs/how_to/structured_output.ipynb` notebook, an
`AIMessage` within the tool-calling few-shot example was missing the
`name="example_assistant"` parameter. This was inconsistent with the
other `AIMessage` instances in the same list.

This change adds the missing `name` parameter to ensure all examples in
the section are consistent, improving the clarity and correctness of the
documentation.

**Issue:** N/A

  1. A test for the integration, preferably unit tests that do not rely on network access,
  2. An example notebook showing its use. It lives in `docs/docs/integrations` directory.

- [ ] **Lint and test**: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified. **We will not consider a PR unless these three are passing in CI.** See [contribution guidelines](https://python.langchain.com/docs/contributing/) for more.

Additional guidelines:

- Make sure optional dependencies are imported within a function.
- Please do not add dependencies to `pyproject.toml` files (even optional ones) unless they are **required** for unit tests.
- Most PRs should not touch more than one package.
- Changes should be backwards compatible.

the current recommended image `jaguardb/jaguardb` for pulling and

a647073b26 feat(standard-tests): add a property to set the name of the parameter for the number of results to return (#32443)
Not all retrievers use `k` as param name to set the number of results to
return. Even in LangChain itself. Eg:
bc4251b9e0/libs/core/langchain_core/indexing/in_memory.py (L31)

So it's helpful to be able to change it for a given retriever.
The change also adds hints to disable the tests if the retriever doesn't
support setting the param in the constructor or in the invoke method
(for instance, the `InMemoryDocumentIndex` in the link supports in the
constructor but not in the invoke method).

This change is backward compatible.

4011257c25 docs: add Windows-specific setup instructions (#32399)
**Description:** This PR improves the contribution setup guide by adding
comprehensive Windows-specific instructions. The changes address a
common pain point for Windows contributors who don't have `make`
installed by default, making the LangChain contribution process more
accessible across different operating systems.
The main improvements include:

- Added a dedicated "Windows Users" section with multiple installation
options for `make` (Chocolatey, Scoop, WSL)
- Provided direct `uv` commands as alternatives to all `make` commands
throughout the setup guide
- Included Windows-specific instructions for testing, formatting,
linting, and spellchecking
- Enhanced the documentation to be more inclusive for Windows developers

This change makes it easier for Windows users to contribute to LangChain
without requiring additional tool installation, while maintaining the
existing workflow for users who already have `make` available.

**Issue:** This addresses the common barrier Windows users face when
trying to contribute to LangChain due to missing `make` commands.

**Dependencies:** None required - this is purely a documentation
improvement.

potential confusion or installation issues.

When building such applications, developers should remember to follow good security practices:
* [**Limit Permissions**](https://en.wikipedia.org/wiki/Principle_of_least_privilege): Scope permissions specifically to the application's need. Granting broad or excessive permissions can introduce significant security vulnerabilities. To avoid such vulnerabilities, consider using read-only credentials, disallowing access to sensitive resources, using sandboxing techniques (such as running inside a container), specifying proxy configurations to control external requests, etc. as appropriate for your application.

* **Anticipate Potential Misuse**: Just as humans can err, so can Large Language Models (LLMs). Always assume that any system access or credentials may be used in any way allowed by the permissions they are assigned. For example, if a pair of database credentials allows deleting data, it's safest to assume that any LLM able to use those credentials may in fact delete data.
* [**Defense in Depth**](https://en.wikipedia.org/wiki/Defense_in_depth_(computing)): No security technique is perfect. Fine-tuning and good chain design can reduce, but not eliminate, the odds that a Large Language Model (LLM) may make a mistake. It's best to combine multiple layered security approaches rather than relying on any single layer of defense to ensure security. For example: use both read-only permissions and sandboxing to ensure that LLMs are only able to access data that is explicitly meant for them to use.

## Message IDs
LangChain messages include an optional `id` field that serves as a unique identifier. Understanding when and how these IDs are assigned can be helpful for debugging, tracing, and working with message history.
### When Messages Get IDs
Messages receive IDs in the following scenarios:
**Automatically assigned by LangChain:**
- When generated through chat model invocation (`.invoke()`, `.stream()`, `.astream()`) with an active run manager/tracing context
- IDs follow the format:
- `run-$RUN_ID` (e.g., `run-ba48f958-6402-41a5-b461-5e250a4ebd36-0`)
- `run-$RUN_ID-$IDX` (e.g., `run-ba48f958-6402-41a5-b461-5e250a4ebd36-1`) when there are multiple generations from a single chat model invocation.
**Provider-assigned IDs (highest priority):**
- When the model provider assigns its own ID to the message
- These take precedence over LangChain-generated run IDs
- Format varies by provider
### When Messages Don't Get IDs
Messages will **not** receive IDs in these situations:
- **Manual message creation**: Messages created directly (e.g., `AIMessage(content="hello")`) without going through chat models
- **No run manager context**: When there's no active callback/tracing infrastructure
### ID Priority System
LangChain follows a clear precedence system for message IDs:
1. **Provider-assigned IDs** (highest priority): IDs from the model provider
2. **LangChain run IDs** (medium priority): IDs starting with `run-`
3. **Manual IDs** (lowest priority): IDs explicitly set by users

This will produce a list of two messages, the first one being a system message, and the second one being the HumanMessage we passed in.
This will produce a list of four messages total: the system message plus the three messages we passed in (two HumanMessages and one AIMessage).
If we had passed in 5 messages, then it would have produced 6 messages in total (the system message plus the 5 passed in).

## Tool Artifacts vs. Injected State
Although similar conceptually, tool artifacts in LangChain and [injected state in LangGraph](https://langchain-ai.github.io/langgraph/reference/agents/#langgraph.prebuilt.tool_node.InjectedState) serve different purposes and operate at different levels of abstraction.
**Tool Artifacts**
- **Purpose:** Store and pass data between tool executions within a single chain/workflow
- **Scope:** Limited to tool-to-tool communication
- **Lifecycle:** Tied to individual tool calls and their immediate context
- **Usage:** Temporary storage for intermediate results that tools need to share
**Injected State (LangGraph)**
- **Purpose:** Maintain persistent state across the entire graph execution
- **Scope:** Global to the entire graph workflow
- **Lifecycle:** Persists throughout the entire graph execution and can be saved/restored
- **Usage:** Long-term state management, conversation memory, user context, workflow checkpointing
Tool artifacts are ephemeral data passed between tools, while injected state is persistent workflow-level state that survives across multiple steps, tool calls, and even execution sessions in LangGraph.
## Best practices
When designing tools to be used by models, keep the following in mind:

### Pre-commit
We use [pre-commit](https://pre-commit.com/) to ensure commits are formatted/linted.
#### Installing Pre-commit
First, install pre-commit:
```bash
# Option 1: Using uv (recommended)
uv tool install pre-commit
# Option 2: Using Homebrew (globally for macOS/Linux)
brew install pre-commit
# Option 3: Using pip
pip install pre-commit
```
Then install the git hook scripts:
```bash
pre-commit install
```
#### How Pre-commit Works
Once installed, pre-commit will automatically run on every `git commit`. Hooks are specified in `.pre-commit-config.yaml` and will:
- Format code using `ruff` for the specific library/package you're modifying
- Only run on files that have changed
- Prevent commits if formatting fails
#### Skipping Pre-commit
In exceptional cases, you can skip pre-commit hooks with:
```bash
git commit --no-verify
```
However, this is discouraged as the CI system will still enforce the same formatting rules.
## Working with optional dependencies
`langchain`, `langchain-community`, and `langchain-experimental` rely on optional dependencies to keep these packages lightweight.

## Snapshot Testing
Some tests use [syrupy](https://github.com/tophat/syrupy) for snapshot testing, which captures the output of functions and compares them to stored snapshots. This is particularly useful for testing JSON schema generation and other structured outputs.
### Updating Snapshots
To update snapshots when the expected output has legitimately changed:
```bash
uv run --group test pytest path/to/test.py --snapshot-update
```
### Pydantic Version Compatibility Issues
Pydantic generates different JSON schemas across versions, which can cause snapshot test failures in CI when tests run with different Pydantic versions than what was used to generate the snapshots.
**Symptoms:**
- CI fails with snapshot mismatches showing differences like missing or extra fields.
- Tests pass locally but fail in CI with different Pydantic versions
**Solution:**
Locally update snapshots using the same Pydantic version that CI uses:
1. **Identify the failing Pydantic version** from CI logs (e.g., `2.7.0`, `2.8.0`, `2.9.0`)
2. **Update snapshots with that version:**
```bash
uv run --with "pydantic==2.9.0" --group test pytest tests/unit_tests/path/to/test.py::test_name --snapshot-update
```
3. **Verify compatibility across supported versions:**
```bash
# Test with the version you used to update
uv run --with "pydantic==2.9.0" --group test pytest tests/unit_tests/path/to/test.py::test_name
# Test with other supported versions
uv run --with "pydantic==2.8.0" --group test pytest tests/unit_tests/path/to/test.py::test_name
```
**Note:** Some tests use `@pytest.mark.skipif` decorators to only run with specific Pydantic version ranges (e.g., `PYDANTIC_VERSION_AT_LEAST_210`). Make sure to understand these constraints when updating snapshots.
## Coverage
Code coverage (i.e. the amount of code that is covered by unit tests) helps identify areas of the code that are potentially more or less brittle.
