description: Create or revise a .madcat/PLAN.md work plan with cadence, chunks, and success criteria.
---

The user invoked `/plan` with argument: `$ARGUMENTS`

If `$ARGUMENTS` is empty, ask the user what they want to work on — use the Question tool with a text input.

Otherwise, use `$ARGUMENTS` as the goal. Create a PLAN.md with:
- goal: the provided argument text
- cadence: ask via Question tool (options: auto-on-green, supervisor, manual) if not obvious from context
- chunks: break the goal into ordered work chunks with success criteria for each

After the plan is created, read `.madcat/PLAN.md` and present it to the user for approval before any execution starts.
