The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.

• check_reversibility

  Evaluate one commitment’s cancellation/refund reversibility from transaction-specific checkout terms plus maintained policy evidence, without charging or creating durable state. Use before a purchase, booking, subscription, rental, service, ticket, digital purchase, or deposit when exit deadlines or loss matter; use list_supported_policies only for maintained-overlay coverage, and create_exit_manifest only after paidExitManifestAvailable=true. Do not use for purchase desirability, legal advice, chargeback decisions, or executing a cancellation. Supply checkout_terms whenever available because

• check_agent_purchase

  Inspect one autonomous HTTP purchase before the calling agent pays it. This $0.01 machine-payment operation validates a real 402 challenge, compares advertised price/protocol/network/asset/payment destination when supplied, checks x402 v2 exact resource binding when available, and surfaces retry or settled-delivery recovery signals. ExitProof never forwards payment credentials and never sends a live POST, PUT, PATCH, or DELETE probe; for those methods the caller supplies an already-observed 402 challenge. Conflicting, malformed, inaccessible, non-402, or unsafe targets are rejected before Exit

• create_exit_manifest

  Persist a privacy-minimized Exit Manifest for an eligible commitment, then return its manifest_id and secret access_token. Use only after check_reversibility says paidExitManifestAvailable=true; pass the exact commitment facts to preserve, with transaction-specific checkout_terms controlling the assessment when supplied. Use check_reversibility for evaluation only, or get_exit_manifest when a manifest already exists. This state-changing $0.25 stablecoin MPP operation checks eligibility before any payment challenge; a fresh authorization creates durable state, while an identical settled retry w

• get_exit_manifest

  Retrieve one previously created Exit Manifest without charging or changing stored state. Pass manifest_id and access_token together: the ID selects the record and the secret token authorizes access to that same record, so neither value is sufficient alone. Use this for preserved evidence and terms; use build_exit_pack for an actionable cancellation/refund plan, or create_exit_manifest when no manifest exists. This free, repeatable read does not refresh, re-evaluate, or extend evidence; missing, expired, or mismatched credentials fail without modifying the manifest.
