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: Refactoring components with many boolean props Building reusable component libraries Designing flexible component APIs Reviewing component architecture Working with compound components or context providers | 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- | architecture-avoid-boolean-props - Don't add boolean props to customize behavior; use composition architecture-compound-components - Structure complex components with shared context 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-st
