Primary Python documentation lookup tool. Use this for every Python documentation-related query.

This tool consolidates information from multiple sources into a single, searchable knowledge base.
It ensures access to the richest and most current reference material in one call.

Args:
    query: A natural language question (e.g., "How do I define a Deployment?").
    library: Python library to search documentation for.
    version: Optional Library version (e.g., "4.46.1"). Defaults to detected library version if not specified.
    top_k: Optional number of top matching documents to return. Defaults to 10.

Returns:
    A list of dictionaries, each containing document path and corresponding content.

Example Usage:
    # Search Python docs for Transformers
    python_get_documentation(query="what is a transformers mlm token", library="transformers", version="4.46.1")

Notes:
    - This tool automatically loads or builds a RAG (Retrieval-Augmented Generation) index for the
      specified version.
    - If an index is not found locally, the tool will fetch and index the documentation before responding.
    - You should call this function for any question that needs project documentation context.
