feat(anthropic): accept TypedDict for built-in tool types ( #34279 )
...
Widen `bind_tools` to accept `TypedDict` via `Mapping` so that users may
import and use Anthropic's built-in tool types:
```python
import subprocess
from anthropic.types.beta import BetaToolBash20250124Param
from langchain.tools import tool
tool_spec = BetaToolBash20250124Param(
name="bash",
type="bash_20250124",
strict=True,
)
@tool(extras={"provider_tool_definition": tool_spec})
def bash(*, command: str, restart: bool = False, **kw):
"""Execute a bash command."""
if restart:
return "Bash session restarted"
try:
result = subprocess.run(
command,
shell=True,
capture_output=True,
text=True,
timeout=30,
)
return result.stdout + result.stderr
except Exception as e:
return f"Error: {e}"
# Bind bash tool to your model
```

refactor(standard-tests): improve VCR config ( #33968 )
...
Use of the fixture `_base_vcr_config` is deprecated with alternative
function `base_vcr_config()`
This way:
* we don't need to import `_base_vcr_config` seen as unused (which leads
to ruff violations PLC0414 and F811)
* we don't need to make a copy since a new dict is created at each
function invocation

feat(langchain): support SystemMessage in create_agent's system_prompt ( #34055 )
...
* `create_agent`'s `system_prompt` allows `str | SystemMessage`
* added `system_message: SystemMessage` on `ModelRequest`
* `ModelRequest.system_prompt` is a function of `system_message.text`,
now deprecated
* disallow setting `system_prompt` and `system_message`
* `ModelRequest.system_prompt` can still be set (w/ custom setattr) for
custom backwards compat, but the updates just get propogated to the
`ModelRequest.system_message`

fix(anthropic): execute bash + file tools via tool node ( #33960 )
...
* use `override` instead of directly patching things on `ModelRequest`
* rely on `ToolNode` for execution of tools related to said middleware,
using `wrap_model_call` to inject the relevant claude tool specs +
allowing tool node to forward them along to corresponding langchain tool
implementations
* making the same change for the native shell tool middleware
* allowing shell tool middleware to specify a name for the shell tool
(negative diff then for claude bash middleware)
long term I think the solution might be to attach metadata to a tool to
map the provider spec to a langchain implementation, which we could also
take some lessons from on the MCP front.
