Scored across 10 tools
Most tools have clearly distinct roles: list/search/get for endpoints, get_field_schema and find_field for field-level drill-down, get_guide for prose, get_docs_info for provenance. The main soft overlaps are list_endpoints vs search_endpoints vs get_endpoint_group (three different ways to browse endpoints) and get_example vs get_response_sample (request example vs response example), but each description explicitly contrasts itself with its neighbour, so an agent can pick correctly.
Every tool is snake_case and follows a verb_noun shape (get_endpoint, list_endpoints, search_endpoints, find_field, get_field_schema, get_endpoint_group). The verb choice (get/list/search/find) is meaningful rather than arbitrary, and get_docs_info is the only slightly loose noun but still fits the pattern.
Ten tools is squarely in the ideal range and each earns its place: catalogue browsing, search, per-endpoint detail, field lookup, field schema drill-down, examples, samples, guides, grouping, and docs provenance. There is no obvious padding or redundant near-duplicate.
For a documentation-browsing domain the surface is thorough: discovery (list/search/group), full endpoint schemas, targeted field drill-down and cross-endpoint field search, request examples, response samples, prose guides (with topic listing when omitted), and documentation version/provenance. I can't identify a meaningful dead end an agent would hit.
