You can undo setup

Setup backs up existing files byte for byte before it writes, and in those files it replaces only the marker blocks it manages. That makes it reversible:

• openplanr runtime rollback restores the last pre-setup state for every managed agent.
• openplanr runtime remove claude removes one agent's OpenPlanr files, as long as they still match what OpenPlanr wrote.

Removal deletes only files OpenPlanr wrote and still recognizes. Modified or unknown files are reported and left in place, so your own edits survive. To remove the planning folder, .planr/, delete it by hand.
