Cancel Skill
Cancel an implementation plan that is no longer being pursued.
Process
-
Identify the plan to cancel:
- If the user specifies a plan number/name, use that
- Otherwise, list in-progress plans and ask user to choose
- Never auto-cancel - always require explicit identification
-
Ask for cancellation reason (optional but recommended):
- "Why is this plan being cancelled?"
- Common reasons: superseded by another plan, requirements changed, no longer needed
- If superseded, ask which plan supersedes it
-
