+# Phase 2 Plan 02-01: Implement Database Schema and API Endpoints Summary
+
+## One-liner
+Implemented database schema and complete CRUD API endpoints for task management functionality with React component for UI rendering.
+
+## Decisions Made
+
+None - plan executed exactly as written.
+
+## Dependencies
+
+### Requires
+- Phase 1: Setup & Authentication (UI, AUTH requirements)
+
+### Provides  
+- Core task management functionality for the application
+- Database schema for storing task data
+- API endpoints for task operations
+- UI component for displaying tasks
+
+### Affects
+- Phase 3: Calendar Integration (CAL requirements) - will need to extend the task model to include calendar event associations
+- Phase 4: Final Polish (UI enhancements and refinement) - will build upon these components
+
+## Tech Stack
+
+### Added
+- Prisma ORM for database modeling
+- SQLite database for development
+- TypeScript interfaces for type safety
+
+### Patterns
+- RESTful API design for task operations
+- Component-based UI architecture with React
+- Database-first approach with Prisma
+
+## Files Created
+
+### Created
+- `prisma/schema.prisma` - Database schema with Task model
+- `src/app/api/tasks/route.ts` - API endpoints for task management
+- `src/components/TaskItem.tsx` - React component for displaying individual tasks
+- `src/types/task.ts` - TypeScript interface for Task model
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Authentication Gates
+
+None - no authentication required for this implementation.
+
+## Metrics
