Agents

• Presence. An agent shows a cursor on the frame or file it's working on, and a soft-lock banner ("Designer agent editing — watch · stop"). Watch its plan items check off live and expand its activity mid-run.
• Interrupt. Hit Stop on the agent's avatar and the task pauses at needs-input. Comment on the frame to course-correct; the agent resumes from its checkpoint with your correction.
• Attribution. Every agent edit is stamped with the agent and the session that made it, with a per-agent activity feed.
• Batch revert. Don't like where a task went? Hit Revert on its receipt and the entire change-set — frames and files — rolls back as one unit. The revert itself is recorded on the thread.
• Parallel work. While an agent builds the checkout page, you keep editing the landing page — soft-locks keep you out of each other's way, no blocking.

Autonomy

You control how far an agent goes on its own — from "propose a plan and wait" to "run the whole task and show me the receipt." Autonomy is per-task and adjustable; higher autonomy still produces the same reviewable receipt and revertable change-set.
