What This Tool Does
Data format validation utility that checks whether input strings conform to standard formats and specifications across a wide range of common data types. It validates JSON syntax and reports parsing errors with specific error locations, verifies email addresses against RFC-compliant patterns while extracting local and domain parts, and checks UUIDs for proper formatting with version detection. Network-related validation includes IPv4 addresses with octet range checking and private or loopback detection, IPv6 addresses with compression and link-local identification, MAC addresses in both colon and hyphen-separated formats, and URLs with scheme and domain parsing. Financial validation covers credit card numbers using the Luhn checksum algorithm with automatic card type detection for Visa, Mastercard, American Express, and Discover, as well as IBAN validation with country code extraction and BBAN parsing using the mod-97 checksum. Additional validators handle phone numbers with international format detection, hexadecimal color codes in both short and long formats with RGB value extraction, ISBN-10 and ISBN-13 with checksum verification, base64 encoding with decoded length reporting, and regex pattern syntax checking. All validators return detailed results including validity status, parsed components, and specific error messages for invalid input.
Product Instructions

Overview
Validate data formats including emails, URLs, JSON, UUIDs, IP addresses, credit cards, phone numbers, colors, ISBNs, IBANs, MAC addresses, Base64, and regex patterns. Each action returns whether the input is valid along with format-specific details.

Common Workflows
- Data ingestion pipeline: Use
validate-jsonto check incoming payloads,validate-emailfor contact fields, andvalidate-urlfor link fields before processing. - Network configuration audit: Combine
validate-ipv4,validate-ipv6, andvalidate-mac-addressto verify device configuration data. - E-commerce checkout: Use
validate-credit-cardto pre-check card numbers,validate-emailfor customer email, andvalidate-phonefor contact number. - Book catalog management: Use
validate-isbnto verify book identifiers during import. - Financial data validation: Use
validate-ibanto verify bank account numbers in international transactions.
Important Notes
- All actions require the
textparameter. - Whitespace, hyphens, and common separators are automatically stripped where appropriate (credit cards, phone numbers, ISBNs, IBANs, MAC addresses).
- Credit card validation uses the Luhn algorithm and detects Visa, Mastercard, American Express, and Discover.
- UUID validation supports versions 1 through 5.
- Phone validation accepts 10-15 digit numbers with optional international (+) prefix.
- IBAN validation uses the mod-97 checksum per ISO 13616.
- Every response includes a
validboolean and a descriptivemessage.

Response Handling
- Treat the returned JSON as the source of truth for this tool call.
- If the response includes warnings or correction targets, apply them before retrying.
- If the response includes a
passedor success-style boolean, use it as the workflow gate. - If validation fails or the response shape is unclear, call
get_schemaorget_instructionsbefore retrying. - If
validate-base64fails, preserve the request parameters and retry only after fixing schema, auth, or payment errors.
Security
- Do not place account secrets, wallet private keys, mnemonics, signatures, or payment headers in prompts or logs.
- Keep tool inputs scoped to the minimum content needed for the task.
- Use the setup skills for credential handling; this product skill only defines product-specific behavior.
