Each tool targets a clearly distinct need: get_certification returns one plugin's record, list_certified enumerates the registry, and certification_spec returns the rules document. The descriptions explicitly cross-reference each other ('use list_certified instead when...'), leaving essentially no room for misselection.

All names use snake_case, and two of three share the verb_ prefix pattern (get_certification, list_certified). Minor deviation: the noun forms differ (certification vs certified) and certification_spec drops the verb entirely, though it reads naturally as a document lookup.

Three tools is on the lean side but proportionate for a read-only registry lookups service: single-record fetch, enumeration, and spec. Nothing feels padded or redundant, though it sits near the thin end of the 3-15 range.

The read-only surface covers the natural lifecycle: discover the registry, fetch a specific record with full evidence, and interpret the grading rules. Minor gap in that there is no filtering/search by grade or dimension, but agents can work around this by listing and reading records.
