name: pattern-discovery description: Pattern library discovery for pattern-first development. Use BEFORE implementing any new feature, creating components, writing API routes, or adding database operations. Ensures existing patterns are checked first.

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

Copyls docs/patterns/api/      # API route patterns
ls docs/patterns/ui/       # UI component patterns
ls docs/patterns/database/ # Database patterns
ls docs/patterns/testing/  # Testing patterns

Step 2: Review Pattern Index

See docs/patterns/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.
