If a run is cancelled or interrupted before a tool returns a result, [`PatchToolCallsMiddleware`](https://reference.langchain.com/python/deepagents/middleware/patch_tool_calls/PatchToolCallsMiddleware) in the same stack repairs the message history automatically. diff --git a/build/oss/python/deepagents/interpreters.mdx b/build/oss/python/deepagents/interpreters.mdx index 74eba724b..ed712e39c 100644 --- a/build/oss/python/deepagents/interpreters.mdx +++ b/build/oss/python/deepagents/interpreters.mdx @@ -4,16 +4,16 @@ description: Run lightweight code inside Deep Agents to compose tools, orchestra tag: "Beta" --- -import InterpretersQuickstartPy from '/snippets/code-samples/interpreters-quickstart-py.mdx'; -import InterpretersQuickstartJs from '/snippets/code-samples/interpreters-quickstart-js.mdx'; -import InterpretersTotalsEvalJs from '/snippets/code-samples/interpreters-totals-eval-js.mdx'; -import InterpretersPtcCallEvalJs from '/snippets/code-samples/interpreters-ptc-call-eval-js.mdx'; -import InterpretersEnablePtcPy from '/snippets/code-samples/interpreters-enable-ptc-py.mdx'; -import InterpretersEnablePtcJs from '/snippets/code-samples/interpreters-enable-ptc-js.mdx'; -import InterpretersPtcParallelEvalJs from '/snippets/code-samples/interpreters-ptc-parallel-eval-js.mdx'; -import InterpretersTaskFanoutEvalJs from '/snippets/code-samples/interpreters-task-fanout-eval-js.mdx'; -import InterpretersPersistenceDefaultPy from '/snippets/code-samples/interpreters-persistence-default-py.mdx'; -import InterpretersPersistenceCheckpointerPy from '/snippets/code-samples/interpreters-persistence-checkpointer-py.mdx'; +import InterpretersQuickstartPy from '/snippets/python/code-samples/interpreters-quickstart-py.mdx'; +import InterpretersQuickstartJs from '/snippets/python/code-samples/interpreters-quickstart-js.mdx'; +import InterpretersTotalsEvalJs from '/snippets/python/code-samples/interpreters-totals-eval-js.mdx'; +import InterpretersPtcCallEvalJs from '/snippets/python/code-samples/interpreters-ptc-call-eval-js.mdx'; +import InterpretersEnablePtcPy from '/snippets/python/code-samples/interpreters-enable-ptc-py.mdx'; +import InterpretersEnablePtcJs from '/snippets/python/code-samples/interpreters-enable-ptc-js.mdx'; +import InterpretersPtcParallelEvalJs from '/snippets/python/code-samples/interpreters-ptc-parallel-eval-js.mdx'; +import InterpretersTaskFanoutEvalJs from '/snippets/python/code-samples/interpreters-task-fanout-eval-js.mdx'; +import InterpretersPersistenceDefaultPy from '/snippets/python/code-samples/interpreters-persistence-default-py.mdx'; +import InterpretersPersistenceCheckpointerPy from '/snippets/python/code-samples/interpreters-persistence-checkpointer-py.mdx'; Interpreters give agents a programmable, **in-memory** workspace inside the agent loop.

It moves synchronous blocking work off the serving API's event loop so health checks stop failing, but the blocking code continues to run on the background loop and **will** continue to cause issues in production, like degraded throughput, tail-latency spikes, starved workers, or connection pool exhaustion (see the pool-size caveat below), and poor scaling under load. + +To properly resolve those issues, use native async drivers and async code throughout your agent. That means async HTTP clients like `httpx` or `aiohttp` (though we recommend caching the clients to avoid CPU overhead loading the SSL context), async database drivers like `asyncpg` or `psycopg[async]`, and async model SDK's.

The localhost hostname is no longer accepted over `http` — use the loopback IP literal or `https`. +- The [MCP servers settings page](/langsmith/fleet/remote-mcp-servers) now scrolls when the pointer is over the servers list. +- When a Fleet agent's subagent calls a tool that requires human approval, the approval prompt now appears in the chat instead of the run completing without it. +- The Executive Assistant template can now deliver its daily brief and answer @mentions in Slack after you connect a Slack workspace, and both the Executive Assistant and Software Engineer templates received configuration fixes. +- You can now type and send a message in agent chat while a human-in-the-loop prompt is pending. Sending a new message dismisses the pending request and continues the conversation instead of leaving the composer locked. +- Empty sections in the agent configuration panel — Channels, Connections, Skills, Schedules, Instructions, and Subagents — now explain what each one is for and what you can add before you connect anything. +- Opening an agent in the chat inbox no longer issues repeated duplicate background requests while choosing which thread to open, reducing flicker. +- Fleet agents now load your workspace's private skills. Previously, in workspaces with fine-grained access controls, an agent could start with only public skills available. +- GitHub App installations now sync through the authenticated LangSmith session after installation completes, keeping workspace linking aligned with the active user. +- OAuth providers now accept an optional default redirect URI (`default_redirect_uri`). When set, headless OAuth flows for that provider return the authorization code to it instead of the LangSmith callback, without passing a redirect on every request.

To log traces to a different project, see [Log traces to a specific project](/langsmith/log-traces-to-project). + + + + +```python Python +import openai +from langsmith import traceable +from langsmith.wrappers import wrap_openai + +client = wrap_openai(openai.Client()) + +@traceable(run_type="tool", name="Retrieve Context") +def my_tool(question: str) -> str: + return "During this morning's meeting, we solved all world conflict." + +@traceable(name="Chat Pipeline") +def chat_pipeline(question: str): + context = my_tool(question) + messages = [ + { "role": "system", "content": "You are a helpful assistant.
