A2A Agent Card Cross-SDK Signature Conformance

check_card runs a new conformance check while get_check fetches an existing record, so the actions are mostly distinct. The shared "check" noun and the unrelated list_watches tool create slight room for confusion, but not serious overlap.

All three tools follow a consistent snake_case verb_noun pattern: check_card, get_check, list_watches. No naming inconsistencies are present.

Three tools is a small but reasonable surface for a narrow conformance-checking service. The count is not excessive, though list_watches feels somewhat orphaned without related watch-management tools.

The surface offers run/get for checks and list for watches, but lacks list_checks, watch creation, watch retrieval, and watch deletion. This creates significant dead ends, especially for watches, which can be listed but not managed.
