## Description
Updates package metadata and README badges so LangChain social links
point to the new `@langchain_oss` X handle. This was completed with
AI-agent assistance.
## Test Plan
- [ ] Validate README badges and package metadata links point to
`https://x.com/langchain_oss `
_Opened collaboratively by Mason Daugherty and open-swe._

perf(langchain): stop inlining agent state into tool-dispatch Sends ( #36960 )
...
## Summary
Stop inlining the full agent state into every tool-dispatch `Send` in
`create_agent`. Dispatch with the bare list form `Send("tools",
[tool_call])` and let `ToolNode` hydrate `ToolRuntime.state` from graph
channels at tool-execution time.
**Depends on**
[langchain-ai/langgraph#7594 ](https://github.com/langchain-ai/langgraph/pull/7594 )
which teaches `ToolNode` to read channel state via `CONFIG_KEY_READ`
when given a bare tool-call list. `uv.lock` pins that branch for CI
while the langgraph PR is in flight — this pin will be reverted to a
published `langgraph` version before merge.
## What was happening
Before this change, every pending tool call produced a `Send` whose
payload was:
```python
ToolCallWithContext(
__type="tool_call_with_context",
tool_call=tool_call,
state=state, # ← the FULL agent state dict, including messages list
)
```
For any agent that runs many turns, `state["messages"]` grows linearly
with the conversation. Every super-step that dispatches tools serializes
that whole list into every `Send`, and those Sends live forever in the
checkpointer's `__pregel_tasks` writes. The result is **O(N²)
`__pregel_tasks` storage** across a run.
## What changed
- `libs/langchain_v1/langchain/agents/factory.py`:
- `_make_model_to_tools_edge` now returns `Send("tools", [tool_call])` —
no inlined state.
- Drops the `ToolCallWithContext` import.
- `libs/langchain_v1/pyproject.toml` + `libs/langchain_v1/uv.lock`:
- Temporary `[tool.uv.sources]` pin on `langgraph`,
`langgraph-prebuilt`, `langgraph-checkpoint` to the companion PR branch
so CI exercises both changes end-to-end. Revert after langgraph release.
## Why it's safe
- Same snapshot semantics as before. `Send` is emitted at the end of the
model super-step and consumed at the start of the tools super-step;
channels by that point reflect every write from the model super-step
(including the new AIMessage). Parallel tool tasks all see the same
values since sibling writes don't land until end-of-super-step.
- Legacy `ToolCallWithContext` input path is preserved in `ToolNode` —
no-op for any external caller still constructing it by hand.
## Test plan
- [x] `tests/unit_tests/agents/` — **738 passed, 2 skipped, 1 xfailed**
- [x] `ruff check .` / `ruff format .` — clean
- [x] `mypy langchain/agents/factory.py` — clean
- [x] Before/after benchmark (below)
## Benchmark
Script runs `create_agent` with a mock `GenericFakeChatModel` and two
tools (`write_file`, `edit_file`). Each of the N turns dispatches 2 tool
calls. After the run, the `InMemorySaver` is inspected for bytes stored
under `__pregel_tasks` — the channel that carries the tool-dispatch
`Send` payloads.
| N | TASKS before | TASKS after | ratio |
|---:|---:|---:|---:|
| 5 | 87.6 KB | **4.7 KB** | **18.6× smaller** |
| 10 | 335 KB | **9.4 KB** | **35.7× smaller** |
| 25 | 2.05 MB | **23.7 KB** | **86.5× smaller** |
| 50 | 8.14 MB | **47.6 KB** | **171× smaller** |
| 100 | 32.5 MB | **95.3 KB** | **341× smaller** |
| 200 | 130 MB | **192 KB** | **677× smaller** |
| 500 | 815 MB | **482 KB** | **1,691× smaller** |
**Growth shape:**
- **Before:** per-Send bytes scale with current `messages` length (full
state is inlined), so total TASKS across N turns = Σ(2 × k) for k=1..N ≈
O(N²).
- **After:** per-Send bytes are constant — just the `tool_call` dict.
Total TASKS is O(#dispatches), completely independent of conversation
length. In this bench with ~2 dispatches/turn: **940–964 bytes per turn
across N=5..500, essentially flat.**
An agent that makes 100 tool calls in a single turn pays the same TASKS
cost as one that makes 100 across 50 turns — which is the semantically
correct behavior.
Note: the `messages` channel is unchanged by this PR — it's still the
dominant storage term (growing O(N²) via `add_messages`). TASKS was a
second, compounding cost sitting on top of it; at N=100 it added 40% on
top of `messages`, at N=500 it added 67%. After the fix, TASKS is a
rounding error regardless of N.

CVE-2025-71176 (medium severity)
All are dev-only (test dependency group) — no impact on published
packages.
### Why syrupy was also bumped
syrupy 4.x (`<5.0.0`) constrains pytest to `<9.0.0`, blocking the CVE
fix. Widening to `<6.0.0` allows syrupy 5.x which supports pytest 9.x.

## Summary
Bumps `pygments` to `>=2.20.0` across all 21 affected packages to
address [CVE-2026-4539](https://github.com/advisories/GHSA-XXXX ) — ReDoS
via inefficient GUID regex in Pygments.
- **Severity:** Low
- **Fixed in:** 2.20.0 (was 2.19.2)
- **Change:** Added `pygments>=2.20.0` to `constraint-dependencies` in
`[tool.uv]` for each package, then ran `uv lock --upgrade-package
pygments` to regenerate lock files.
Closes Dependabot alerts #3435–#3455.

<h1>v82.0.0</h1>
<h2>Deprecations and Removals</h2>
<ul>
<li><code>pkg_resources</code> has been removed from Setuptools. Most
common uses of <code>pkg_resources</code> have been superseded by the
<code>importlib.resources
<https://docs.python.org/3/library/importlib.resources.html> ;</code>_
and <code>importlib.metadata
<https://docs.python.org/3/library/importlib.metadata.html> ;</code>_
projects. Projects and environments relying on
<code>pkg_resources</code> for namespace packages or other behavior
should depend on older versions of <code>setuptools</code>. (<a
href="https://redirect.github.com/pypa/setuptools/issues/3085 ">#3085</a>)</li>
</ul>
<h1>v81.0.0</h1>
<h2>Deprecations and Removals</h2>
<ul>
<li>Removed support for the --dry-run parameter to setup.py. This one
feature by its nature threads through lots of core and ancillary
functionality, adding complexity and friction. Removal of this parameter
will help decouple the compiler functionality from distutils and thus
the eventual full integration of distutils. These changes do affect some
class and function signatures, so any derivative functionality may
require some compatibility shims to support their expected interface.
Please report any issues to the Setuptools project for investigation.

<h2>Bug fixes</h2>
<ul>
<li>
<p><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13896 ">#13896</a>:
The terminal progress feature added in pytest 9.0.0 has been disabled by
default, except on Windows, due to compatibility issues with some
terminal emulators.</p>
<p>You may enable it again by passing <code>-p terminalprogress</code>.
We may enable it by default again once compatibility improves in the
future.</p>
<p>Additionally, when the environment variable <code>TERM</code> is
<code>dumb</code>, the escape codes are no longer emitted, even if the
plugin is enabled.</p>
</li>
<li>
<p><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13904 ">#13904</a>:
Fixed the TOML type of the <code>tmp_path_retention_count</code>
settings in the API reference from number to string.</p>
</li>
<li>
<p><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13946 ">#13946</a>:
The private <code>config.inicfg</code> attribute was changed in a
breaking manner in pytest 9.0.0.
Due to its usage in the ecosystem, it is now restored to working order
using a compatibility shim.
It will be deprecated in pytest 9.1 and removed in pytest 10.</p>
</li>
<li>
<p><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13965 ">#13965</a>:
Fixed quadratic-time behavior when handling <code>unittest</code>
subtests in Python 3.10.</p>
</li>
</ul>
<h2>Improved documentation</h2>
<ul>
<li><a
href="https://redirect.github.com/pytest-dev/pytest/issues/4492 ">#4492</a>:
The API Reference now contains cross-reference-able documentation of
<code>pytest's command-line flags

<h2>Removed</h2>
<ul>
<li>Support for Python 3.9 (<a

</ul>
<h2>Added</h2>
<ul>
<li>Support for pytest 9 (<a

</ul>
<h2>Notes for Downstream Packagers</h2>
<ul>
<li>Tested Python versions include free threaded Python 3.14t (<a
href="https://redirect.github.com/pytest-dev/pytest-asyncio/issues/1274 ">#1274</a>)</li>
<li>Tests are run in the same pytest process, instead of spawning a
subprocess with <code>pytest.Pytester.runpytest_subprocess</code>. This
prevents the test suite from accidentally using a system installation of
pytest-asyncio, which could result in test errors. (<a

post</a> for a migration guide and overview of the changes!</p>
<h3>Breaking changes</h3>
<ul>
<li>
<p>Ruff now formats your code according to the 2026 style guide. See the
formatter section below or in the blog post for a detailed list of
changes.</p>
</li>
<li>
<p>The linter now supports block suppression comments. For example, to
suppress <code>N803</code> for all parameters in this function:</p>
<pre lang="python"><code># ruff: disable[N803]
def foo(
legacyArg1,
legacyArg2,
legacyArg3,
legacyArg4,
): ...

Updates `setuptools` to 82.0.0

<blockquote>
<h1>v82.0.0</h1>
<h2>Deprecations and Removals</h2>
<ul>
<li><code>pkg_resources</code> has been removed from Setuptools. Most
common uses of <code>pkg_resources</code> have been superseded by the
<code>importlib.resources
<https://docs.python.org/3/library/importlib.resources.html> ;</code>_
and <code>importlib.metadata
<https://docs.python.org/3/library/importlib.metadata.html> ;</code>_
projects. Projects and environments relying on
<code>pkg_resources</code> for namespace packages or other behavior
should depend on older versions of <code>setuptools</code>. (<a
href="https://redirect.github.com/pypa/setuptools/issues/3085 ">#3085</a>)</li>
</ul>
<h1>v81.0.0</h1>
<h2>Deprecations and Removals</h2>
<ul>
<li>Removed support for the --dry-run parameter to setup.py. This one
feature by its nature threads through lots of core and ancillary
functionality, adding complexity and friction. Removal of this parameter
will help decouple the compiler functionality from distutils and thus
the eventual full integration of distutils. These changes do affect some
class and function signatures, so any derivative functionality may
require some compatibility shims to support their expected interface.
Please report any issues to the Setuptools project for investigation.

feat: support state updates from wrap_model_call with command(s) ( #35033 )
...
Alternative to https://github.com/langchain-ai/langchain/pull/35024 .
Paving the way for summarization in `wrap_model_call` (which requires
state updates).
---
Add `ExtendedModelResponse` dataclass that allows `wrap_model_call`
middleware to return a `Command` alongside the model response for
additional state updates.
```py
@dataclass
class ExtendedModelResponse(Generic[ResponseT]):
model_response: ModelResponse[ResponseT]
command: Command
```
## Motivation
Previously, `wrap_model_call` middleware could only return a
`ModelResponse` or `AIMessage` — there was no way to inject additional
state updates (e.g. custom state fields) from the model call middleware
layer. `ExtendedModelResponse` fills this gap by accepting an optional
`Command`.
This feature is needed by the summarization middleware, which needs to
track summarization trigger points calculated during `wrap_model_call`.
## Why `Command` instead of a plain `state_update` dict?
We chose `Command` rather than the raw `state_update: dict` approach
from the earlier iteration because `Command` is the established
LangGraph primitive for state updates from nodes. Using `Command` means:
- State updates flow through the graph's reducers (e.g. `add_messages`)
rather than being merged as raw dicts. This makes messages updates
additive alongside the model response instead of replacing them.
- Consistency with `wrap_tool_call`, which already returns `Command`.
- Future-proof: as `Command` gains new capabilities (e.g. `goto`,
`send`), middleware can leverage them without API changes.
## Why keep `model_response` separate instead of using `Command`
directly?
The model node needs to distinguish the model's actual response
(messages + structured output) from supplementary middleware state
updates. If middleware returned only a `Command`, there would be no
clean way to extract the `ModelResponse` for structured output handling,
response validation, and the core model-to-tools routing logic. Keeping
`model_response` explicit preserves a clear boundary between "what the
model said" and "what middleware wants to update."
Also, in order to avoid breaking, the `handler` passed to
`wrap_tool_call` needs to always return a `ModelResponse`. There's no
easy way to preserve this if we pump it into a `Command`.
One nice thing about having this `ExtendedModelResponse` structure is
that it's extensible if we want to add more metadata in the future.
## Composition
When multiple middleware layers return `ExtendedModelResponse`, their
commands compose naturally:
- **Inner commands propagate outward:** At composition boundaries,
`ExtendedModelResponse` is unwrapped to its underlying `ModelResponse`
so outer middleware always sees a plain `ModelResponse` from
`handler()`. The inner command is captured and accumulated.
- **Commands are applied through reducers:** Each `Command` becomes a
separate state update applied through the graph's reducers. For
messages, this means they're additive (via `add_messages`), not
replacing.
- **Outer wins on conflicts:** For non-reducer state fields, commands
are applied inner-first then outer, so the outermost middleware's value
takes precedence on conflicting keys.
- **Retry-safe:** When outer middleware retries by calling `handler()`
again, accumulated inner commands are cleared and re-collected from the
fresh call.
```python
class Outer(AgentMiddleware):
def wrap_model_call(self, request, handler):
response = handler(request) # sees ModelResponse, not ExtendedModelResponse
return ExtendedModelResponse(
model_response=response,
command=Command(update={"outer_key": "val"}),
)
class Inner(AgentMiddleware):
def wrap_model_call(self, request, handler):
response = handler(request)
return ExtendedModelResponse(
model_response=response,
command=Command(update={"inner_key": "val"}),
)
# Final state merges both commands: {"inner_key": "val", "outer_key": "val"}
```
## Backwards compatibility
Fully backwards compatible. The `ModelCallResult` type alias is widened
from `ModelResponse | AIMessage` to `ModelResponse | AIMessage |
ExtendedModelResponse`, but existing middleware returning
`ModelResponse` or `AIMessage` continues to work identically.
## Internals
- `model_node` / `amodel_node` now return `list[Command]` instead of
`dict[str, Any]`
- `_build_commands` converts the model response + accumulated middleware
commands into a list of `Command` objects for LangGraph
- `_ComposedExtendedModelResponse` is the internal type that accumulates
commands across layers during composition

feat: threading context through create_agent flows + middleware ( #34978 )
...
Closes https://github.com/langchain-ai/langchain/issues/33956
* Making `ModelRequest` generic on `ContextT` and `ResponseT` so that we
can thread type information through to `wrap_model_call`
* Making builtin middlewares generic on `ContextT` and `ResponseT` so
their context and response types can be inferred from the `create_agent`
signature
See new tests that verify backwards compatibility (for cases where folks
use custom middleware that wasn't parametrized).
This fixes:
1. Lack of access to context and response types in `wrap_model_call`
2. Lack of cohesion between middleware context + response types with
those specified in `create_agent`
See examples below:
### Type-safe context and response access
```python
class MyMiddleware(AgentMiddleware[AgentState[AnalysisResult], UserContext, AnalysisResult]):
def wrap_model_call(
self,
request: ModelRequest[UserContext],
handler: Callable[[ModelRequest[UserContext]], ModelResponse[AnalysisResult]],
) -> ModelResponse[AnalysisResult]:
# ✅ Now type-safe: IDE knows user_id exists and is str
user_id: str = request.runtime.context["user_id"]
# ❌ mypy error: "session_id" doesn't exist on UserContext
request.runtime.context["session_id"]
response = handler(request)
if response.structured_response is not None:
# ✅ Now type-safe: IDE knows sentiment exists and is str
sentiment: str = response.structured_response.sentiment
# ❌ mypy error: "summary" doesn't exist on AnalysisResult
response.structured_response.summary
return response
```
### Mismatched middleware/schema caught at `create_agent`
```python
class SessionMiddleware(AgentMiddleware[AgentState[Any], SessionContext, Any]):
...
# ❌ mypy error: SessionMiddleware expects SessionContext, not UserContext
create_agent(
model=model,
middleware=[SessionMiddleware()],
context_schema=UserContext, # mismatch!
)
class AnalysisMiddleware(AgentMiddleware[AgentState[AnalysisResult], ContextT, AnalysisResult]):
...
# ❌ mypy error: AnalysisMiddleware expects AnalysisResult, not SummaryResult
create_agent(
model=model,
middleware=[AnalysisMiddleware()],
response_format=SummaryResult, # mismatch!

feat: dynamic tool registration via middleware ( #34842 )
...
dependent upon https://github.com/langchain-ai/langgraph/pull/6711
1. relax constraint in `factory.py` to allow for tools not
pre-registered in the `ModelRequest.tools` list
2. always add tool node if `wrap_tool_call` or `awrap_tool_call` is
implemented
3. add tests confirming you can register new tools at runtime in
`wrap_model_call` and execute them via `wrap_tool_call`
allows for the following pattern
```py
from langchain_core.messages import HumanMessage, ToolMessage
from langchain_core.tools import tool
from libs.langchain_v1.langchain.agents.factory import create_agent
from libs.langchain_v1.langchain.agents.middleware.types import (
AgentMiddleware,
ModelRequest,
ToolCallRequest,
)
@tool
def get_weather(location: str) -> str:
"""Get the current weather for a location."""
return f"The weather in {location} is sunny and 72°F."
@tool
def calculate_tip(bill_amount: float, tip_percentage: float = 20.0) -> str:
"""Calculate the tip amount for a bill."""
tip = bill_amount * (tip_percentage / 100)
return f"Tip: ${tip:.2f}, Total: ${bill_amount + tip:.2f}"
class DynamicToolMiddleware(AgentMiddleware):
"""Middleware that adds and handles a dynamic tool."""
def wrap_model_call(self, request: ModelRequest, handler):
updated = request.override(tools=[*request.tools, calculate_tip])
return handler(updated)
def wrap_tool_call(self, request: ToolCallRequest, handler):
if request.tool_call["name"] == "calculate_tip":
return handler(request.override(tool=calculate_tip))
return handler(request)
agent = create_agent(model="openai:gpt-4o-mini", tools=[get_weather], middleware=[DynamicToolMiddleware()])
result = agent.invoke({
"messages": [HumanMessage("What's the weather in NYC? Also calculate a 20% tip on a $85 bill")]
})
for msg in result["messages"]:
msg.pretty_print()
```

description by @mdrxy
- Enable `test_responses_spec.py` integration tests that were previously
skipped at module level
- Widen `ToolStrategy.schema` type annotation from `type[SchemaT]` to
`type[SchemaT] | dict[str, Any]` to match actual supported usage (JSON
schema dicts were already handled at runtime)
- Fix type annotations and linting issues in test file (modernize to
`dict`/`list`, add return types, prefix unused `_request` param)
- Improve generic typing in `load_spec` utility with bounded `TypeVar`
