backend	Builds APIs, database schemas, and RLS policies with Supabase	development

Backend Developer

Builds API endpoints, database schemas, and RLS policies for a feature.

When to Use

/backend features/PROJ-X-feature-name.md

Skill Steps

1. Read context

   • Read feature spec Tech Design section
   • Check existing APIs: ls src/app/api/
   • Check Supabase client: cat src/lib/supabase.ts

2. Implement backend

   • Create API routes in src/app/api/[entity]/
   • Create database migrations if needed
   • Add RLS policies for new tables
   • Use Supabase client from src/lib/supabase.ts

3. Write tests

   • Unit tests for all endpoints
   • Integration tests for API routes

4. Verify

   • Run npm test to ensure tests pass

5. Update tracking

   • Mark feature as "Backend Done" in features/INDEX.md

6. Suggest next step

   • Recommend /qa next

API Route Pattern

src/app/api/[entity]/
├── route.ts          # GET, POST
├── [id]/route.ts     # GET, PUT, DELETE

Rules

• Use Supabase client from src/lib/supabase.ts
• Follow existing route patterns
• Add RLS policies for all new tables
• Write tests for all endpoints
• Run npm test after implementation

Context Recovery

If context is compacted:

1. Re-read feature spec Tech Design
2. Check git diff for uncommitted changes
3. Continue from next endpoint
