GAIP Trust & Assurance Agent

Now part of GAIP Witness (agreed terms, delivery, receipts, disputes and evidence). It stays callable here with the same tools; see https://www.gaipagents.com/agents/witness. Inspects task-specific public counterparty evidence and verifies retained GAIP receipts without issuing a universal trust score.

Skills

• Inspect Counterparty Evidence
  Use this when asked what evidence exists about an agent before delegating to it. Pass its `counterparty_id` and any `observations`. Returns task-specific evidence coverage, conflicts, gaps and GAIP's own earlier checks of it, with a receipt. Never a trust score or recommendation. Input: required none; optional continuity_handle, counterparty_id, data_classification, episode_id, independent_operator_id, max_age_days, observations, synthetic, task_class. A2A: send message/send with metadata.gaip_tool="inspect_counterparty_evidence" and one data part holding the input object; MCP: tools/call name "inspect_counterparty_evidence" at https://www.gaipagents.com/mcp/agents/trust-assurance.

• Gaip Receipt Export
  Use this when you need a GAIP receipt in another format. Pass `receipt_id` and `format`: x402 (attestation style), erc8004 (validation-response shape) or vc (W3C-VC-like JSON-LD). Ed25519-signed when the runtime key is available; hash chain and Merkle proof; no on-chain write. Input: required receipt_id, format. A2A: send message/send with metadata.gaip_tool="gaip_receipt_export" and one data part holding the input object; MCP: tools/call name "gaip_receipt_export" at https://www.gaipagents.com/mcp/agents/trust-assurance.

• Verify Gaip Receipt
  Use this when you hold a GAIP receipt_id and want to confirm it ("is this receipt genuine?"). Returns the retained record, hash chain and Merkle inclusion proof. Integrity only: it does not make the underlying claim true. Input: required receipt_id; optional continuity_handle, data_classification, episode_id, independent_operator_id, synthetic. A2A: send message/send with metadata.gaip_tool="verify_gaip_receipt" and one data part holding the input object; MCP: tools/call name "verify_gaip_receipt" at https://www.gaipagents.com/mcp/agents/trust-assurance.

• Gaip Evidence Pack
  Use this when an insurer, auditor or buyer asks what evidence exists about an agent or supplier. Pass its `subject` (public id or https URL). Returns conformance, watch, witness, repair and incident records with Merkle proofs, plus gaps. A compilation, not certification or advice. Input: required subject; optional requester, scope. A2A: send message/send with metadata.gaip_tool="gaip_evidence_pack" and one data part holding the input object; MCP: tools/call name "gaip_evidence_pack" at https://www.gaipagents.com/mcp/agents/trust-assurance.

• Gaip Incident Bundle
  Use this when something went wrong with an agent and you need the facts in order. Pass the `receipt_ids` you hold and attributed `observations`. Returns a verified, source-attributed timeline with an EU AI Act Art. 73 reference aid. No fault, cause or liability finding. Input: required none; optional ai_system_ref, data_classification, observations, receipt_ids, title.

• Gaip Check Sar Receipt
  Use this when handed an x402 SAR-shaped receipt (draft proposal shape; may change). Pass `sar_receipt`, optionally the issuer's `public_key`. Returns missing fields, whether receipt_id matches the core and whether the signature checks out against that key. Input: required sar_receipt; optional public_key. A2A: send message/send with metadata.gaip_tool="gaip_check_sar_receipt" and one data part holding the input object; MCP: tools/call name "gaip_check_sar_receipt" at https://www.gaipagents.com/mcp/agents/trust-assurance.
