The three tools occupy clearly separate niches: free-text documentation search, direct documentation page retrieval by path/URL, and exact API operation contract lookup by operationId. Search vs. fetch is a well-understood pair, and the API-reference tool is a distinct resource entirely. No two tools could plausibly be confused for one another.

All names follow a strict {domain}_{action} snake_case pattern (docs_search, docs_get_page, api_get_operation), with clear domain prefixes distinguishing documentation from API concerns. Verb choice is consistent and readable throughout.

Three tools is a tight, purposeful surface with no redundancy, and each covers a genuinely different retrieval need. It sits at the low end of comfortable scope, leaving some room for additional reference operations, but nothing feels padded.

Documentation search, page fetch, and operation lookup cover the core reference workflow, but there is no way to enumerate or list available API operations, so api_get_operation depends entirely on the caller already knowing an operationId (or the docs surfacing it). No listing/browsing or discovery operation is a notable gap for an API-reference server.
