+# AI Agent Instructions for ng-in-viewport
+
+## Project Overview
+
+This is an Angular library for viewport detection using modern Angular v20+ patterns and signals. The library provides efficient viewport intersection detection using the Intersection Observer API.
+
+### Repository Structure
+- `projects/ng-in-viewport/` - Core library source code
+- `projects/demo/` - Demo application for documentation
+- `projects/example/` - Example application showing real-world usage
+- `e2e/` - End-to-end tests
+- `docs/` - Documentation files
+
+## Development Guidelines
+
+### Angular Standards
+- Use Angular v20+ features exclusively (signals, modern control flow)
+- All components must be standalone with OnPush change detection
+- Use signal-based APIs and computed values
+- Prefer `inject()` over constructor dependency injection
+- Use modern template syntax (`@if`, `@for`, `@switch`)
+
+### Code Quality
+- TypeScript strict mode enabled
+- ESLint and Prettier configured
+- Jest for unit testing
+- Playwright for E2E testing
+- 100% code coverage expected for library code
+
+### Key Commands
+```bash
+# Development
+npm run build:lib        # Build library
+npm run test:lib         # Test library
+npm run lint             # Lint all projects
+npm run format           # Check formatting
+npm run serve:demo       # Run demo app (port 4200)
+npm run serve:example    # Run example app (port 4300)
+
+# Testing
+npm run test             # All tests with coverage
+npm run e2e:run          # E2E tests headless
+npm run e2e:open         # E2E tests with UI
+```
+
+## Library Architecture
+
+### Core Components
+- `InViewportDirective` - Main directive for viewport detection
+- `InViewportService` - Service managing intersection observers
+- Signal-based state management throughout
+
+### Key Features
+- Intersection Observer API integration
+- Signal-based reactivity
+- SSR-compatible (graceful degradation)
+- TypeScript first with strict typing
+- Angular standalone components
+
+## Testing Strategy
+
+### Unit Tests
+- Test all public APIs
+- Mock Intersection Observer for browser compatibility
+- Test signal reactivity and computed values
+- Verify SSR compatibility
+
+### E2E Tests
+- Test real viewport interactions
+- Verify performance with many elements
+- Test responsive behavior
+- Validate accessibility
+
+## Performance Requirements
+- Library bundle size < 10KB gzipped
+- Zero runtime dependencies
+- Efficient memory usage with proper cleanup
+- 60fps performance during scroll operations
+
+## Compatibility
+- Angular 16+ (with standalone component support)
+- Modern browsers with Intersection Observer
+- Server-side rendering support
+- TypeScript 5.0+
+
+## Contributing Guidelines
+- Follow conventional commits
+- Ensure all tests pass
+- Maintain code coverage
+- Update documentation for API changes
+- Use Angular best practices from latest version
+
+## AI Assistant Context
+When helping with this project:
+1. Always use modern Angular patterns (v20+ features)
+2. Prioritize performance and bundle size
+3. Maintain TypeScript strict compliance
+4. Ensure cross-browser compatibility
+5. Test thoroughly with provided test suites
+6. Follow the existing code patterns and architecture
+
+## Common Tasks
+- Adding new directive features
+- Optimizing intersection observer performance
+- Updating for new Angular versions
+- Enhancing TypeScript definitions
+- Improving test coverage
+- Updating documentation examples
