-Break the following request into a numbered plan with concrete file paths and
-acceptance criteria. Do not implement until I approve.
+---
+description: Create a structured implementation plan before coding
+argument-hint: "[task or feature]"
+subagent: true
+fork: true
+---
+Create a structured implementation plan for: $@
+
+Follow this format:
+1. **Goal** — one-sentence objective
+2. **Constraints** — existing code, dependencies, tests, or assumptions to respect
+3. **Approach** — high-level strategy and rationale
+4. **Steps** — numbered, actionable tasks small enough to verify one at a time
+5. **Verification** — how to confirm each step works (tests, logs, manual checks)
+6. **Risks & Rollbacks** — what could go wrong and how to undo safely
+7. **Open Questions** — anything that needs clarification before starting
+
+Use the codebase context as needed. Do not write implementation code yet; only produce the plan.
