Most tools have clear boundaries: fetch_url retrieves a specific URL, lib_docs fetches library docs by name, list_docs works with local files. The main overlap is between web_search and search_docs, both performing web searches, though search_docs is specifically biased to official documentation and is local-first, which distinguishes it. Descriptions are detailed enough to disambiguate in practice.

All names use lowercase snake_case with an underscore, and most follow a verb_noun pattern (fetch_url, search_docs, list_docs). However, web_search is noun_verb order and lib_docs is noun_noun, which are minor deviations from the dominant pattern. Overall the style is consistent and readable.

Five tools is a well-scoped size for a documentation reference server. Each tool serves a clear function: web search, URL fetching, library-specific fetching, docs search, and local docs browsing. This is within the ideal 3-15 range and there is no bloat.

The tool set covers the full workflow for web documentation research: searching the web, fetching pages, retrieving library docs, searching with docs bias, and managing local saved docs. The optional saving via fetch_url and lib_docs, plus list_docs for browsing, avoids dead ends. No critical gaps are evident for the documented purpose.
