Proof primitive for AI agents on MultiversX. Anchor file hashes on-chain as verifiable proofs.

Scored across 13 tools
Most tools have clearly distinct purposes (file certification, decision certification, coherence anchoring, session audit, attestations, calibration, proof retrieval/verification). Minor overlap exists between get_proof and verify_proof, and between check_coherence and require_coherence_anchor, but descriptions clarify their different roles (retrieve vs verify, create vs check).
The vast majority follow a verb_noun pattern (audit_agent_session, certify_file, check_attestations, discover_services, get_calibration, get_proof, investigate_proof, register_trial, require_coherence_anchor, submit_outcome, verify_proof). One deviation: certify_with_confidence uses a verb_with_noun structure, but it's still readable and the pattern is otherwise consistent.
13 tools is well-scoped for a blockchain certification service covering discovery, trial, certification creation, verification, coherence anchoring, calibration, and investigation. Each tool addresses a specific workflow step without redundancy or bloat.
The core certification lifecycle (create, verify, retrieve) is fully covered, along with coherence anchors, calibration tracking, and investigation. A notable gap is the lack of a list or search tool to enumerate proofs for a wallet, but agents can work around it if proof IDs are known or provided by other flows.
