| description | Use when refactoring code - tracks the refactor in task docs and preserves behavior through small verified changes |
<skill_overview>
Refactor in small truth-preserving steps. Keep the refactor tracked in task docs and stop if behavior starts drifting.
</skill_overview>
<rigidity_level>
MEDIUM FREEDOM - Keep the change→test→document loop strict, but adapt the exact refactor pattern to the codebase.
</rigidity_level>
<quick_reference>
- Create or resume a refactor task directory
- Capture invariants and risks in
plan.md
- Make one small change at a time
- Run tests between steps
- Update
context.md and tasks.md
</quick_reference>
<when_to_use>
- Behavior should stay the same
- The current design is painful to change
- You need a deliberate, reversible refactor path
</when_to_use>
<the_process>
1. Track the refactor
Use task docs to capture:
- invariants that must not change
- risks
- target design
2. Refactor in tiny steps
Each step should be small enough to explain and verify on its own.
3. Verify every step
Run the smallest relevant tests after each change.
4. Keep docs current
Update discoveries, remaining risks, and next slices as the refactor unfolds.
