VAID — Verifiable Agent Identity

A VAID is a signed statement about an agent: its class, tenant, scope boundary, capability set, validity window, and its parent in a delegation chain. It is Ed25519-signed over canonical bytes, so anyone holding the issuer's public key can check it with no network call, no credential from the issuer, and no permission from anyone.

This skill is a thin wrapper over the published vaid-mint SDK. It implements no cryptography of its own. The Rust, Python and TypeScript mints are locked byte-for-byte to shared conformance vectors; anything this skill did differently would be a bug in this skill.

The four verbs

There are exactly four, and there is no fifth.
