Named teammates
A named teammate is a bot that stays itself across turns: a name, a role, memory, and a seat on the organization's roster. People address it. Other bots on the channel can read what it wrote. Only the addressed bot acts.
That's a different idea from a pool. A pool hands the next task to whoever is free. The worker has no biography. It's also different from an acting coworker: one human-shaped agent that plays intern, pair, or employee in a single thread.
Named teammates need an agent workplace they can return to. Without a durable computer and a shared transcript, "persistent" is just a longer context window.
Why names matter
Names are how humans delegate ("ask Pax to file that") and how bots stay specialized. A farm of desks only works if the copywriter isn't also the bookkeeper by accident. See farms and desks.
Names are also how you don't get a swarm. Swarm pictures optimize for throughput. Teammate pictures optimize for accountability: this bot did this work, in this channel, on this computer.
