Defines an optional 'auth' tag that lets an owner key authorize an agent key via a BIP-340 Schnorr signature. The agent carries the 64-byte proof in its events. Anyone can verify the relationship without querying a relay. The two keys are independent — agent compromise does not compromise the owner. Reuses NIP-26's proven signing mechanism with different semantics: the event author stays as the agent. The tag is a credential, not an identity override. Relays require no changes.

Adds a draft NIP spec for proving agent-to-owner key relationships on nostr.
What
An optional
authtag that lets an owner key authorize an agent key via a BIP-340 Schnorr signature. The agent carries the 64-byte proof in its events. Anyone can verify the relationship without querying a relay. The two keys are independent — agent compromise does not compromise the owner.Why
AI agents need verifiable provenance. Agents run LLMs that can be prompt-injected, so key derivation schemes (where agent secret leak → owner secret compromised) are not viable. This NIP uses independent keys with a signed attestation instead.
Reuses NIP-26's proven signing mechanism with different semantics: the event author stays as the agent. The tag is a credential, not an identity override. Relays require no changes.
