## What it does

This skill structures messy UI overhauls into four stages: stabilizing behavior with tests, extracting sub-components, simplifying state, and auditing performance alongside accessibility. It targets files exceeding 300 lines, prop drilling, and tightly coupled presentation logic.

The plan recommends specific patterns like Context or Zustand for state management, memoization via `useMemo` and `useCallback`, virtualization, and semantic markup with ARIA tags. Rollout strategies include feature flags and incremental releases to minimize breaking changes.

Completion criteria are strict. The skill requires test coverage above 80% and an accessibility score of at least 95. If your project lacks tests, the initial phase demands writing them before component refactoring begins.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add patricio0312rev/skills --skill frontend-refactor-planner -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/frontend-refactor-planner/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/frontend-refactor-planner/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add patricio0312rev/skills --skill frontend-refactor-planner -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/frontend-refactor-planner/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add patricio0312rev/skills --skill frontend-refactor-planner -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/frontend-refactor-planner/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install patricio0312rev/skills frontend-refactor-planner
```

2. **Manually: put the files in place**
- File: `.github/skills/frontend-refactor-planner/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add patricio0312rev/skills --skill frontend-refactor-planner -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/patricio0312rev/skills --path frontend/frontend-refactor-planner
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/frontend-refactor-planner/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add patricio0312rev/skills --skill frontend-refactor-planner -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/patricio0312rev/skills/tree/HEAD/frontend/frontend-refactor-planner/SKILL.md

## When to use it
- split UI components over 300 lines into smaller modules
- eliminate prop drilling by migrating state to Zustand or Context
- apply memoization and code splitting to sluggish interfaces
- integrate keyboard navigation and ARIA attributes
- outline safe refactoring stages with rollback plans

## Example prompts
- Create a refactoring plan for this 450-line `UserProfile.tsx` component
- Plan state extraction from props to Zustand for the checkout flow
- Outline a staged refactor to fix accessibility and keyboard focus in the modal

# Frontend Refactor Planner

Create safe, phased refactor plans for complex frontend code.

## Refactor Assessment

**Identify Issues**: Large components (>300 lines), prop drilling, duplicate logic, poor performance, accessibility gaps, tight coupling, untested code
**Prioritize**: By risk (high-traffic pages first) and impact (user-facing bugs prioritized)
**Plan Phases**: Break into small, testable increments

## Common Refactor Patterns

**Component Splitting**: Extract sub-components, create compound components, separate logic from presentation
**State Management**: Lift state up, move to Context/Zustand, remove unnecessary state
**Performance**: Memoization (useMemo/useCallback), code splitting, lazy loading, virtualization
**Accessibility**: Add ARIA labels, keyboard navigation, focus management, semantic HTML
**Testing**: Add tests before refactoring, test after each change

## Phased Approach

**Phase 1 - Stabilize**: Add tests, fix critical bugs, document current behavior
**Phase 2 - Extract**: Pull out utilities, create smaller components, reduce complexity
**Phase 3 - Simplify**: Remove dead code, consolidate duplicates, optimize state
**Phase 4 - Polish**: Performance optimization, accessibility audit, documentation

## Risk Mitigation

Feature flags for gradual rollout, A/B testing refactored vs original, monitor error rates, have rollback plan, peer review all changes, incremental deployment.

## Done Criteria

Code coverage >80%, performance metrics improved, accessibility score 95+, no regressions in tests, code review approved, documentation updated.
