Search Python documentation. Use kind='symbol' for API lookups (asyncio.TaskGroup), kind='example' for code samples, kind='auto' otherwise. When version is omitted, searches across all versions. Pass the version from each hit's version field to get_docs for consistent results.

Retrieve a documentation page or specific section. Provide anchor for section-only retrieval (much cheaper). Pagination via start_index.

Look up package-declared docs/homepage/source URLs via official PyPI metadata.

This is not generic web search: it only queries PyPI's JSON API and returns official PyPI metadata plus package-declared project URLs.

List Python documentation versions available in this index.

Detect the Python version in the user's environment. Returns the detected version, how it was found, and whether it matches an indexed documentation set.

Diff a Python stdlib symbol between two indexed versions. Returns change=added|removed|changed|unchanged with optional new_in, changed_in, deprecated_in, signature_delta (advisory), see_also_added/removed, section_diff, and note fields. Both versions must be indexed; otherwise an actionable error names the available versions.
