Each tool has a clearly distinct role: search runs a new web query, fetch reads a known URL, read_result pages through previously stored results without calling providers, and health reports provider/cache state. The boundary between search and fetch is explicit (query vs. known URL), so an agent can select without confusion.

Names are all lowercase snake_case and readable, with three simple single-word tools (search, fetch, health) and one verb_noun compound (read_result). This is mostly consistent, but the lack of a uniform verb_noun pattern keeps it from a perfect score.

Four tools is a well-scoped set for a web search/fetch server: search, fetch, paged result reading, and diagnostics each cover a necessary part of the workflow without redundancy. No tool feels extraneous or missing in count.

For a read-only retrieval domain, the lifecycle is covered: search creates result ids, read_result pages stored results without providers, fetch reads known URLs including special forum APIs, and health exposes configuration and probe diagnostics. No obvious operational gap remains for agent use.
