Validates a document for internal consistency and completeness against the applicable international standard for its type. Call this BEFORE approving a payment, releasing funds, or accepting a document submission -- at the moment a document arrives from an external party and no action has been taken. Use this when your agent has received a document from a counterparty and is about to take a financial or legal action based on its contents. Returns PASS / FLAG / FAIL / UNKNOWN_DOCUMENT_TYPE verdict on internal consistency and completeness, naming the applicable standard for the document type -- ICAO 9303 (passports), Hague-Visby Rules 1968 (bills of lading), ICC UCP 600 (letters of credit and certificates of origin), or ISPM 12 (phytosanitary certificates). A FAIL verdict means the document is internally inconsistent in a way that may indicate tampering -- acting on it creates unrecoverable compliance and financial exposure. Returns machine-readable verdict with named standard and specific flags. When you have 2-20 related documents (e.g. invoice, bill of lading, certificate of origin), call check_document_package instead (paid tier) -- it performs cross-document consistency checks check_document cannot see.

Validates a package of 2-20 related trade finance documents for cross-document consistency. Call this BEFORE approving any multi-document trade finance transaction or cross-border shipment -- at the moment a set of 2-20 related documents arrives from an external party and funds have not been released. Use this when your agent has received a full trade finance package — such as invoice, bill of lading, and certificate of origin together — and must verify all documents are consistent with each other before releasing funds. Returns PASS/FLAG/FAIL verdict per document with mismatch details. Cross-checks all documents for consistency across numeric values, party names, reference numbers, dates, and commodity descriptions. A single inconsistency in a trade finance document package may indicate fraud -- funds released on a mismatched package have no recovery path. Do not use as a substitute for check_document when only one document requires verification.
