summary: 'Identify an identifier''s kind: UUID version, ULID, KSUID, snowflake…'
description: 'Classifies up to 100 identifier strings by format and, where it can be read, decodes the embedded timestamp, for an agent that must not pass an id of the wrong kind to a payment, ledger or API call. Recognises UUID (RFC 9562 version and variant, nil and max), ULID, KSUID, Discord and Twitter snowflakes, EIP-55 EVM addresses (checksum verified), email (WHATWG syntax and RFC 5321 length limits), E.164 shape, Stripe object prefixes (cus_, pi_, ch_ ...), GitHub token prefixes and AWS IAM unique-id prefixes, each match citing its source. Several valid readings (an all-digit 19-digit id is both a Discord and a Twitter snowflake) return unknown with every reading; with `expect` the answer is pass or fail for that kind. A prefix match is a candidate, not proof of the vendor; nothing is looked up in any registry. Credential-shaped values (GitHub tokens, AWS access keys) are never echoed.
