PR fix notes

PR #37214: docs: add missing prompt docstrings to qa chain loaders

Description (problem / solution / changelog)

Fixes #37222


This PR adds proper Python docstrings to the _load_stuff_chain and _load_map_reduce_chain functions, resolving the existing TODO document prompt comments.

Changed files

  • libs/langchain/langchain_classic/chains/question_answering/chain.py (modified, +43/-2)
RAW_BUFFERClick to expand / collapse

The internal chain loader functions and in have comments but lack actual docstrings. This makes it unclear what the parameter expects.
