| Tool | Description |
|---|---|
| validate_iban | Validate an IBAN: mod-97 checksum, country code, and country-specific length. Returns the normalized and print-formatted IBAN. LLM-generated IBANs almost always fail this check. |
| validate_isbn | Validate an ISBN-10 or ISBN-13 check digit. For valid ISBN-10, also returns the ISBN-13 conversion. Hyphens and spaces allowed. |
| validate_ean | Validate an EAN-8, UPC-A (12), EAN-13 or GTIN-14 barcode check digit. Returns the expected check digit on failure. |
| validate_uuid | Validate a UUID's format and report its version and variant. Catches malformed UUIDs that merely look plausible. |
| validate_ulid | Validate a ULID (26-char Crockford base32) and decode its embedded timestamp to ISO 8601. |
