Plan mode is a read-only autonomy posture for AI sessions, picked from the chat footer. The assistant can only investigate; anything that writes, runs or deploys is refused until it hands over a plan and you approve it, which restores the posture you were in before. Session chats only, and never persisted.
New features
- Plan (read-only) joins Ask permission and Yolo in the autonomy picker of a session chat.
- Only read-only tools run while planning; writes, job runs and deploys are refused with a "Blocked in plan mode" row.
- You enter plan mode from the picker, or by accepting the "Start planning?" card the assistant raises on open-ended tasks.
- The proposed plan is shown for approval with "Approve and implement" or "Keep planning"; approving restores the exact posture that preceded plan mode.
- One versioned plan document per session, pinned to the top of the artifacts list, with the approved version marked and unapproved revisions labeled as drafts.
