Several `core` modules do not have descriptions, like the [agent](https://api.python.langchain.com/en/latest/core_api_reference.html#module-langchain_core.agents) module. - Added missed module descriptions.

ccurme	1b0802babe	core: fix .bind when used with RunnableLambda async methods (#17739) ... **Description:** Here is a minimal example to illustrate behavior: ```python from langchain_core.runnables import RunnableLambda def my_function(*args, **kwargs): return 3 + kwargs.get("n", 0) runnable = RunnableLambda(my_function).bind(n=1) assert 4 == runnable.invoke({}) assert [4] == list(runnable.stream({})) assert 4 == await runnable.ainvoke({}) assert [4] == [item async for item in runnable.astream({})] ``` Here, `runnable.invoke({})` and `runnable.stream({})` work fine, but `runnable.ainvoke({})` raises ``` TypeError: RunnableLambda._ainvoke.<locals>.func() got an unexpected keyword argument 'n' ``` and similarly for `runnable.astream({})`: ``` TypeError: RunnableLambda._atransform.<locals>.func() got an unexpected keyword argument 'n' ``` Here we assume that this behavior is undesired and attempt to fix it. **Issue:** https://github.com/langchain-ai/langchain/issues/17241, https://github.com/langchain-ai/langchain/discussions/16446	5 months ago

Eugene Yurtsev	93472ee9e6	core[patch]: Replace memory stream implementation used by LogStreamCallbackHandler (#17185) ... This PR replaces the memory stream implementation used by the LogStreamCallbackHandler. This implementation resolves an issue in which streamed logs and streamed events originating from sync code would arrive only after the entire sync code would finish execution (rather than arriving in real time as they're generated). One example is if trying to stream tokens from an llm within a tool. If the tool was an async tool, but the llm was invoked via stream (sync variant) rather than astream (async variant), then the tokens would fail to stream in real time and would all arrived bunched up after the tool invocation completed.	5 months ago
