Refactor with Safety

Perform structural changes while preserving behavior and stability.

Workflow

1. Preparation

   • Audit: Read AGENTS.md for domain constraints.
   • Baseline: Run tests (pnpm run test) to ensure everything passes before you start.
   • Coverage: If tests are missing for the target, add them first (use golden-path-test-author).

2. Execution

   • Small Steps: Refactor one function/component at a time.
   • Interface Preservation: Keep function signatures stable if possible.
   • Linting: Run pnpm run lint frequently to catch syntax errors.

3. Verification

   • Test: Run pnpm run test after each change.
   • Build: Run pnpm run build to ensure no circular dependencies or export errors.
   • Review: Check if the logic is actually simpler/better.

Rules

• No Behavior Change: Unless explicitly requested, refactoring should not alter logic.
• Fix the Code, Not the Test: If a test fails, the refactor is wrong (unless the test was testing implementation details).
• Commit Often: Use change-plan-conventional-commits.

Example

Input: "Refactor calculateScore to be more readable."

Action:

1. Run tests/score.test.js. (Passes).
2. Break calculateScore into getBaseScore and getMultipliers.
3. Run tests/score.test.js. (Passes).
4. Run pnpm run lint. (Passes).

Output: "Extracted helper functions getBaseScore and getMultipliers. Tests pass. Logic is unchanged but clearer."

Skill sync: compatible with React 19.2.6 / Vite 8.0.10 / Tailwind 4.2.4 baseline as of 2026-05-20.
