audit_openapi targets a single document (lint/auth review) while compare_openapi targets two documents (breaking-change diff), so the action and input shape differ clearly. They share the same domain and both are static analysis, so an agent could momentarily hesitate, but the descriptions disambiguate well.
Both tools follow the same verb_noun snake_case pattern (audit_openapi, compare_openapi), with the noun being the OpenAPI artifact. Fully predictable and readable.
Two tools is thin for a server presented as an API guardian; linting and diffing are the core operations but little else is exposed. It is borderline rather than mismatched, since the stated scope is narrow.
Auditing and comparing cover the main lifecycle of reviewing OpenAPI specs, with honest scope caveats in the descriptions. Gaps exist (no spec fetching/resolution, no remediation or validation-report output tooling), but agents can work around them.
