Agents

Here an agent is a specialist role that the main coding agent hands part of a task to. A separate agent can have fewer powers than the main one, or another model, and that is the point: the reviewer cannot edit code, so it can only judge.

Agent	Why	When it runs
code-reviewer	An agent that reviews its own work tends to approve it, so a separate reviewer judges the finished change.	During /wettaq, after the final checks and the browser pass, for substantial changes: once to find problems, and at most once more to confirm the fixes.
ui-designer	Interface work needs design judgement that general coding instructions do not carry, such as hierarchy, spacing and states.	When a run, or you, hands it UI work: designing a new screen or reshaping an existing one.
