vercel-composition-patterns
React composition patterns that scale. Use when refactoring components with boolean prop proliferation, building flexible component libraries, or designing reusable APIs. Triggers on tasks involving compound components, render props, context providers, or component architecture. Includes React 19 API changes.
Why this skill is useful
Provides specific React composition patterns and guidelines that enhance component architecture and state management, which the AI may not generate reliably on its own.

What this skill does
React Composition Patterns Composition patterns for building flexible, maintainable React components. Avoid boolean prop proliferation by using compound components, lifting state, and composing internals. These patterns make codebases easier for both humans and AI agents to work with as they scale. When to Apply Reference these guidelines when: Refactoring components with many boolean props Building reusable component libraries Designing flexible component APIs Reviewing component architecture Working with compound components or context providers Rule Categories by Priority Priority Category Impact Prefix -------- ----------------------- ------ --------------- 1 Component Architecture HIGH architecture- 2 State Management MEDIUM state- 3 Implementation Patterns MEDIUM patterns- 4 React 19 APIs MEDIUM react19- Quick Reference 1. Component Architecture (HIGH) architecture-avoid-boolean-props - Don't add boolean props to customize behavior; use composition architecture-compound-components - Structure complex components with shared context 2. State Management (MEDIUM) state-decouple-implementation - Provider is the only place that knows how state is managed state-context-interface - Define generic interface with state, actions, meta for dependency injection state-lift-state - Move state into provider components for sibling access 3. Implementation Patterns (MEDIUM) patterns-explicit-variants - Create explicit variant components instead of boolean modes patterns-children-over-render-props - Use children for composition instead of renderX props 4. React 19 APIs (MEDIUM) ⚠️ React 19+ only. Skip this section if using React 18 or earlier. …
