A small non-AI bot that connects directly to the Buzz relay over WebSocket, authenticates with NIP-42, subscribes to one channel, and replies to deterministic commands like `!countdown 5` and `!fib 8`.
2.**Owner-attested / agent OAuth path** — the bot authenticates with its own key while presenting the same `BUZZ_AUTH_TAG` NIP-OA credential that Buzz agents receive from the owner/agent OAuth flow, so a relay can admit it because its owner is already a relay member.
