Atinamos Evidence

evaluate_policy, get_assurance_receipt, and search_services are clearly distinct, but lookup_evidence and lookup_assurance_evidence both return observations/evidence for an exact service endpoint, and service_history also overlaps by returning observation history for a service route. Descriptions differentiate evidence types and receipts, but the agent must still infer which lookup to use for a given evidence need.

Most tools follow a verb_noun pattern (evaluate_policy, get_assurance_receipt, lookup_evidence, search_services), and the two lookup_* variants are consistent. service_history breaks the pattern by using a noun phrase without a verb, a minor deviation.

Six tools is well-scoped for a read-only evidence and procurement API covering lookup, signed receipt retrieval, policy evaluation, service search, and service history. No tool feels redundant, and the count is neither thin nor heavy.

The surface covers lookup, signed receipt retrieval, policy evaluation, service search, and service history, which is most of the domain. However, it lacks explicit tools for verifying a receipt or listing policy options, and it is unclear whether all evidence lookup paths (e.g., by receipt ID) are covered.
