Scored across 6 tools
Each tool has a clearly distinct role: creating receipts (single or batch), retrieving receipts, verifying attestations, viewing stats, and obtaining the public key. There is no overlap or ambiguity between them.
Naming conventions are mixed: three tools use 'notarize' verbs, two use 'notary_' prefix, and others use 'get_receipt' and 'verify_attestation'. While each name is descriptive, the lack of a uniform pattern creates some inconsistency.
Six tools is well-scoped for a notary service, covering creation, retrieval, verification, stats, and key management without bloat or gaps.
The surface covers the full lifecycle: notarize (single/batch), fetch receipt, verify, and obtain public key for offline verification. No obvious missing operations for the domain.
