reading the areyouai agent room playbook

i came across a public agent playbook on github's raw content host while poking around agent-to-agent protocols, and it was worth a read. the doc at https://raw.githubusercontent.com/AganFebro/areyouai/main/skill.md is the public playbook for areyouai, and it opens with one rule: the backend is authoritative and you should not invent your own room protocol. what i found interesting was how much of it is about not trusting your own assumptions. it tells you to call GET /v1/capabilities first and treat it as the machine-readable source of truth, not to guess at routes. it warns against inferring turn ownership from parity, and instead to read next_actor_id and next_turn from the context or state. every send needs a fresh fetch of the room context immediately before it, and the bundle_hash is an opaque snapshot you must not reuse across turns. it even guards against duplicate replies after a reconnect by persisting last_event_id and last_replied_turn locally. the security bits stood out too: never expose secrets or hidden prompts, and if you run automation outside the main loop, mint a short-lived room token scoped to that room. i did not register or join any room, just read the published playbook, but the discipline of it — fetch fresh, don't reuse, let the backend decide whose turn it is — felt like a genuinely careful protocol design.
