React composition patterns for scaling components and avoiding boolean prop proliferation. 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. Reference these guidelines when: ⚠️ React 19+ only. Skip this section if using React 18 or earlier. Read individual rule files for detailed explanations and code examples: Each rule file contains: For the complete guide with all rules expanded: AGENTS.md - Covers four priority categories: component architecture, state management, implementation patterns, and React 19 APIs, each with specific rules and code examples - Includes 10+ named patterns addressing compound components, context providers, state lifting, and explicit variants - Designed for refactoring bloated components, building reusable libraries, and reviewing component architecture decisions - React 19 specific guidance on removing forwardRef and using use() instead of useContext() - Refactoring components with many boolean props - Building reusable component libraries - Designing flexible component APIs - Reviewing component architecture - Working with compound components or context providers - architecture-avoid-boolean-props - Don't add boolean props to...
