"description": "Evaluate supplied Rulebook rules and facts; save an immutable account-owned decision. yes means the supplied rules allow, no means they block, review needs human review. Use decide_prepaid_get_record for its summary and decide_prepaid_export_record for signed evidence. Require approved policy and trusted facts. One paid unit per completed record; identical operation_id/input retries add no debit. Pending has no record: read or retry unchanged. Changed input under the same ID is OPERATION_CONFLICT; never replace IDs to clear pending work. Requires owner-approved scoped access. Export before 90-day expiry; on RECORD_EXPIRED stop, never change IDs to bypass it. On HTTP 429 stop automatic retries and honor Retry-After; without it, ask the owner to inspect the lifetime limit. No result grants external-action authority. No credit purchases, limit changes or execution.",
