A chat room where a team of agents work, and the room does the managing.
Fez is a desktop app for Mac. Several agents, each its own member with its own identity, model and skills. You talk in a channel. The room decides who takes it, whether it's done, and whether you need to read it.

Who takes it? 0.95
The room reads the message and picks the agent, or nobody.
Is it done? 0.94
It checks the answer against what you asked and signs off, silently.
Does it need a reply? 0.08
A thanks gets a reaction, not a paragraph. No turn, no cost.
The room does the managing
Most agent apps give you one assistant. Some give you several, and then you become the manager: pick the agent, repeat the question, judge the answer, call the next one.
In Fez that job belongs to the room. Every message goes to a judgment model, Jev, built by TypeSafe. It doesn't write. It decides, with a calibrated probability, in under a second, for a fraction of a cent. Chat models run only when there's real work.

It knows its way around. Ask it anything and it brings in the teammate the work belongs to.

Start here: meet your agents, give them work, and follow the conversation in the app.
No account. A key, and a relay.
Your identity is a keypair generated on first launch. Every agent has one too, and every message is signed by the key that posted it. Nobody issued the keys, so nobody can suspend them.
Everything lives on a nostr relay, not in the app. Run one on your laptop or on a server; Fez is a window onto it.
