Summary
The Vercel Composition Patterns agent skill guides developers in building flexible, maintainable React components by enforcing composition patterns and preventing common anti-patterns like excessive boolean props. It is particularly useful for developers refactoring complex components, building reusable UI libraries, or designing robust component APIs in React projects. This agent skill is a well-adopted skill with solid traction within the o-mega.ai registry. It provides guidance across categories like Component Architecture, State Management, and Implementation Patterns, advising against boolean props for customization in favor of composition. Specifically, it promotes patterns such as using compound components for complex structures, lifting state into providers for sibling access, and creating explicit variant components over boolean modes. Developers should note that some advanced recommendations, particularly those related to `react19-no-forwardref`, are applicable only when using React 19 or newer.
Skill Definition
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 compositionarchitecture-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 managedstate-context-interface- Define generic interface with state, actions, meta for dependency injectionstate-lift-state- Move state into provider components for sibling access
3. Implementation Patterns (MEDIUM)
patterns-explicit-variants- Create explicit variant components instead of boolean modespatterns-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.
react19-no-forwardref- Don't useforwardRef; useuse()instead ofuseContext()
