fix(core): `_parse_google_docstring` mishandling continuation lines with colons (#35680) ## Description `_parse_google_docstring` incorrectly parses multi-line argument descriptions when a continuation line contains a colon. The continuation line is treated as a new argument definition instead of being appended to the current argument's description. ### Example ```python def search(query: str, top_k: int = 5) -> str: """Search the knowledge base. Args: query: The search query to use for finding things: important ones top_k: Number of results to return """ ``` **Before (broken):** The parser creates 3 args: `query`, `for finding things`, `top_k` **After (fixed):** The parser correctly creates 2 args: `query` (with full description including "for finding things: important ones"), `top_k` ### Root Cause The parser used `if ":" in line` to detect new argument lines without considering indentation. In Google-style docstrings, continuation lines have deeper indentation than argument definition lines. ### Fix Detect the base indentation level from the first argument line and treat any line with deeper indentation as a continuation of the current argument's description, regardless of whether it contains a colon. ## Issue Fixes #35679 ## Dependencies None. ## Testing Added 4 unit tests in `test_function_calling.py::TestParseGoogleDocstring`: - `test_continuation_line_with_colon` — the core bug scenario - `test_simple_args_still_work` — regression check for basic args - `test_continuation_line_without_colon` — multi-line descriptions without colons - `test_multiple_continuation_lines_with_colons` — multiple continuation lines each containing colons All tests pass locally with Python 3.12. --------- Co-authored-by: gambletan <ethanchang32@gmail.com> Co-authored-by: Mason Daugherty <github@mdrxy.com>

fix(core): add messages to bare `raise ValueError` calls (#38158) Closes #35727 --- Several internal code paths raised a bare `ValueError` with no message, so when one of these conditions tripped, users saw a traceback with no explanation of what actually went wrong. This adds descriptive messages to each of those `raise ValueError` calls: - `FewShotPromptWithTemplates._get_examples` / `_aget_examples` — when neither `examples` nor `example_selector` is set. - Prompt `loading` — when a referenced template file uses an unsupported (non-`.txt`) format. - The LangSmith document loader — when both `client` and `client_kwargs` are supplied. - The Anthropic file-search middleware brace expansion — for unbalanced or empty brace patterns.

fix(core): use `asyncio.get_running_loop()` in async contexts (#38157) Closes #35726 --- Several async functions called `asyncio.get_event_loop()`, which has been deprecated since Python 3.10. Inside `async def` bodies the loop is always running, so `asyncio.get_running_loop()` is the correct, warning-free replacement with no behavior change. This updates the call in `_ahandle_event_for_handler` (core callbacks), `_render_mermaid_using_pyppeteer` (core runnables graph), and `async_api_key_wrapper` (`langchain-openai` client utils). Users running on modern Python no longer see `DeprecationWarning`s from these paths. Made by [Open SWE](https://openswe.vercel.app) Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>
