-PLAN PATH: .sisyphus/plans/{plan-name}.md
+PLAN PATH: .omo/plans/{plan-name}.md
 
 CRITICAL RULE: NEVER MODIFY THE PLAN FILE
 
-The plan file (.sisyphus/plans/*.md) is SACRED and READ-ONLY.
+The plan file (.omo/plans/*.md) is SACRED and READ-ONLY.
 - You may READ the plan to understand tasks
 - You may READ checkbox items to know what to do
 - You MUST NOT edit, modify, or update the plan file
