## Task Status: TypeScript API Contracts
**Agent:** Coder-Beta
**Status:** complete
**Worktree:** /home/ani/Projects/community-ade-wt/api-contracts
**Completed:**
- `src/types/index.ts` - All shared TypeScript interfaces (Task, Worker, QueueStats, etc.)
- `src/api/validation.ts` - Zod schemas for request/response validation
- `src/api/middleware.ts` - Auth, error handling, logging middleware
- `src/api/routes.ts` - Express route definitions with full typing
- `src/index.ts` - Package entry point and exports
- `package.json` - Dependencies (Express, Zod, TypeScript)
- `tsconfig.json` - TypeScript configuration

**Blockers:** none
**Next:** Integration with other worktrees (queue-core, worker-pool)
**Time Remaining:** 0 minutes (task complete)

**API Routes Implemented:**
- GET /api/health - Health check
- GET /api/tasks - List tasks with filters
- POST /api/tasks - Create task
- GET /api/tasks/:id - Get task by ID

- GET /api/queue/stats - Queue statistics
- GET /api/queue/next - Get next available task (worker poll)

**Success Criteria Met:**
- All types compile without errors
- Zod schemas properly validate request/response data
- Routes are fully typed with Express
- Middleware includes auth, logging, error handling, and validation
