Cryptographically sign and verify AgentSkill directories using Ed25519 (RFC 8032). Publishers sign skills with a private key; recipients verify with a public key, proving the skill is unmodified AND authored by the trusted key holder. Pure Python — no pip install, no native dependencies. Use when you say sign skill, verify skill, ed25519 sign, verify skill authenticity, prove skill author, detect skill tampering, give skill a signature, 给 skill 签名, 验证 skill 是谁发的, 校验 skill 没被改过.
