# Pattern Discovery Skill
## Purpose
Enforce pattern-first development by checking the pattern library before implementing new functionality.
## When to Use
- About to create a new API route
- About to create a new UI component
- About to add database operations
- User asks "how do I implement..." or "how should I build..."
## Pattern Discovery Protocol
**ALWAYS check patterns before writing new code:**
### Step 1: Check Pattern Library
```bash
ls patterns_library/api/ # API route patterns
ls patterns_library/ui/ # UI component patterns
ls patterns_library/database/ # Database patterns
ls patterns_library/testing/ # Testing patterns
```
### Step 2: Review Pattern Index
See `patterns_library/README.md` for the complete index.
### Step 3: Apply or Escalate
**If pattern exists:** Copy, customize, validate.
**If missing:** Search codebase, implement following conventions, report gap.
## Pattern Matching Guide
| If you need to... | Use this pattern |
| ---------------------------------- | --------------------------------- |
| Create authenticated API endpoint | `api/user-context-api.md` |
| Create admin-only API endpoint | `api/admin-context-api.md` |
| Handle external webhooks | `api/webhook-handler.md` |
| Validate API input with Zod | `api/zod-validation-api.md` |
| Create protected page | `ui/authenticated-page.md` |
| Build form with validation | `ui/form-with-validation.md` |
| Add new table with RLS | `database/rls-migration.md` |
| Test API endpoints | `testing/api-integration-test.md` |
