Learn Skill

Purpose

Analyze problem-solving patterns, debugging techniques, and workarounds from sessions to save them as reusable skills.

Core Principle: Recurring problem-solving → Pattern extraction → Skill creation → Reuse in future sessions

Activation Triggers

• After solving complex errors
• When discovering useful workarounds
• When establishing project-specific conventions
• Session end knowledge consolidation
• Explicit user request: /learn, remember this, save pattern

Pattern Extraction Focus

1. [HIGH VALUE] NextAuth + Prisma Session Type Extension
   - Problem: userId missing in Session type
   - Solution: Type extension in next-auth.d.ts
   - Reusability: ⭐⭐⭐⭐⭐

2. [MEDIUM VALUE] Supabase RLS Debugging Pattern
   - Problem: Empty results due to RLS policy
   - Solution: Test with service_role key, then fix policy
   - Reusability: ⭐⭐⭐⭐

3. [LOW VALUE] ESLint Rule Disable
   - Problem: unused-vars warning
   - Solution: .eslintrc modification
   - Reusability: ⭐⭐ (project-specific)

# NextAuth + Prisma Session Type Extension

## Problem
Type error when accessing userId in NextAuth session
`Property 'userId' does not exist on type 'Session'`

## Solution
Create `types/next-auth.d.ts`:
\`\`\`typescript
import { DefaultSession } from "next-auth"

declare module "next-auth" {
  interface Session {
    user: {
      id: string
    } & DefaultSession["user"]
  }
}
\`\`\`

## When to Apply
- When using NextAuth + Prisma combination
- When adding custom fields to session

## Related
- NextAuth official docs: TypeScript section
- Prisma adapter configuration

Integration

With PM Agent

Integration with PM Agent's self-improvement layer:

Session complete
    │
    ├─→ /learn (pattern extraction)
    │
    └─→ PM Agent (documentation, knowledge base update)

With /checkpoint

/checkpoint create "before-experiment"
... experimental resolution attempts ...
... success! ...
/learn  # Save successful pattern

With Future Sessions

Quality Filters

Value Assessment

Extraction Threshold

• Low: Extract most patterns (noisy)
• Medium: Medium+ value only (recommended)
• High: High-value patterns only (strict)

Commands

Best Practices

Good Pattern Example

# React Server Component Data Fetching

## Problem
Waterfall issue when fetching server data
in client components

## Solution
Fetch data in server component, pass as props
or use Suspense + parallel fetch

## Code Example
\`\`\`tsx
// ✅ Good: Server Component
async function Page() {
  const data = await fetchData()
  return <ClientComponent data={data} />
}
\`\`\`

Pattern to Avoid

# Fix Typo in Config  ❌
## Problem
Build failure due to typo
## Solution
Fix typo

→ No reuse value, do not save
