Before you relay or act on a claim-backed answer from another agent, check whether every claim is grounded. 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 — allow_relay, verify_before_relay, or block_unsafe_claims — with the unsafe and weak claims, evidence gaps, and owner actions. Schema-level and structural only — not factual-truth verification, source retrieval, or an approval.

Agent output relay-readiness gateTurns another agent's claim set and evidence into a machine-actionable relay verdict — allow_relay, verify_before_relay, or block_unsafe_claims — with the ungrounded and weak claims, evidence gaps, and the owner actions needed before the output is safe to relay. Structural claim-support triage, not factual-truth verification.
-
Pre-action evidence gateRoutes a caller-controlled action to continue, request_evidence, require_approval, or stop using supplied claim evidence, risk tier, policy checks, and external approval status. It reports readiness only and does not authenticate, authorize, enforce, or perform the action.
-
Evidence gap and orphan-reference analysisFinds missing evidence ids, quote-to-reference mismatches, unsupported statements, and weak claims in a caller-supplied claim set. Returns the evidence gaps and owner actions already produced by the relay-readiness contract. Structural only: it does not retrieve sources or verify factual truth.
