-
-## Valid Reasons for Cancellation
-
-- Requirements changed
-- Feature deprecated
-- Duplicate of another task
-- Strategic pivot
-- Technical approach invalidated
-
-## Pre-Cancellation Checks
-
-1. Confirm no critical dependencies
-2. Check for partial implementation
-3. Verify cancellation rationale
-4. Document lessons learned
-
-## Execution
-
-```bash
-task-master set-status --id=$ARGUMENTS --status=cancelled
-```

-   - Recalculate timelines
-
-2. **Clean-up Actions**
-   - Remove related branches
-   - Archive any work done
-   - Update documentation
-   - Close related issues
-
-3. **Learning Capture**
-   - Document why cancelled
-   - Note what was learned
-   - Update estimation models
-   - Prevent future duplicates
-
-## Historical Preservation
-
-- Keep for reference
-- Tag with cancellation reason
