The three tools have mostly distinct purposes: listing repositories, querying docs, and fetching a README. However, query_preact_docs and get_preact_readme could overlap conceptually since a README is documentation, creating minor ambiguity about which to use for repo-specific content.

All tool names follow a consistent verb_noun pattern with the same preact prefix: query_preact_docs, get_preact_readme, and list_preact_repositories. The convention is predictable and easy to parse.

With only 3 tools, the set is well-scoped for a focused Preact documentation server. Each tool earns its place by covering discovery, querying, and README retrieval without unnecessary extras.

The surface covers the core documentation workflow: list available repositories, query docs across them, and fetch a repository README. Minor gaps remain, such as fetching a specific document by path or listing files within a repository, but agents can likely work around these via the query tool.
