A spend cap the run can't blow past, and a list of actions it has to ask a human about first.

A list of roles, and the lead agent hands each one a single task instead of the whole chat history.

A disposable Linux box with a shell, a filesystem, and a real browser that pauses when the agent sleeps.

Built for production

A typed client, a CLI, and a REST endpoint — the same operation in all three. The spend cap is part of the config, so every agent has a ceiling from the moment it exists.
