Each tool has a clearly distinct function: list_categories enumerates categories, search_tools finds tools by query, and get_tool fetches full detail for a single id. There is no overlap—an agent can unambiguously pick the right tool for browsing versus searching versus drilling into a specific item.

All three names follow a clean verb_noun snake_case pattern (list_categories, search_tools, get_tool), with the domain noun consistently referring to tools/categories. This is a fully predictable convention.

Three tools form a minimal but coherent surface for a read-only directory service: browse categories, search, and fetch details. It is slightly thin—there is no equivalent of a plain 'list all tools'—but each tool clearly earns its place.

For a read-only tool directory, the list/search/get trio covers the essential browse-and-inspect lifecycle, and search_tools even documents edge cases like empty results and bilingual queries. Minor gaps like bulk listing or filter facets exist but are workaround-able via search.
