This is a frozen copy of the agent's agent-card.json as we observed it at the timestamp above. We capture a new snapshot every time the card's content hash changes. Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

"description": "Check an AI answer against supplied source text before human review: find broken evidence references, quote mismatches and unsupported claims. 5 free live attempts on your own input at /v1/agent-output/trial, subject to shared-network and fleet daily limits. Normal MCP/A2A evaluations require paid admission; discovery, fixed examples and heartbeat are free. Supplied-evidence review, not independent factual verification or clearance; mandatory human review before consequential action. Caller must invoke and enforce the result in its integration. Before relaying another agent's answer, use an external evidence-review boundary to check the claims against supplied source text. An A2A-compatible relay-readiness gate for agent-to-agent output hand-off: bring the claim set and its evidence; get a machine-actionable verdict \u2014 verify_before_relay, block_unsafe_claims, not_decision_ready, or insufficient_information \u2014 with the unsafe and weak claims, evidence gaps, and owner actions. Caller-declared evidence is never externally verified here, so allow_relay is never issued: the strongest verdict is verify_before_relay with mandatory human review, and a quote counts as grounded only when its text appears in the cited evidence content. Schema-level and structural only \u2014 not factual-truth verification, source retrieval, or an approval.",
