# Frontend Refactor Planner > Creates safe refactor plans for messy UI code including component splitting strategies, state simplification, performance optimizations, and accessibility improvements. Provides phased approach, risk assessment, and "done" criteria. Use when refactoring "legacy code", "messy components", "performance issues", or "large files". - Skill: `tomevault-io/frontend-refactor-planner` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/frontend-refactor-planner` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/frontend-refactor-planner/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Web & Frontend - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/frontend-refactor-planner --- # 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. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/patricio0312rev) — claim your Tome and manage your conversions.
