## Tools

- `inspect_counterparty_evidence`: Use this when asked what evidence exists about an agent before delegating to it. Pass its `counterparty_id` and any `observations`.
- `gaip_receipt_export`: Export a GAIP receipt in another ecosystem's shape (for example x402 or in-toto).
- `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.
- `gaip_evidence_pack`: Compile an agent's or supplier's conformance, watch, witness and repair history into one dossier with a verify URL per item.
- `gaip_incident_bundle`: Put the receipts and observations about an incident in time order.
- `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`.
