best-practices（最佳实践）

Best Practices - View Your Pattern Library

Display your aggregated best practices library, showing successful patterns and anti-patterns across all projects.

Usage

/best-practices                     # Show full library
/best-practices <category>          # Filter by category
/best-practices --warnings          # Show only anti-patterns
/best-practices --successes         # Show only successes
/best-practices --stats             # Show statistics only

Options

• <category> - Filter by specific category (pagination, database, authentication, etc.)
• --warnings - Show only anti-patterns (failed patterns)
• --successes - Show only successful patterns
• --stats - Show statistics summary without individual patterns

Workflow

1. Query mem0 for Best Practices

Use the mem0 CLI script:

python3 ${CLAUDE_PLUGIN_ROOT}/src/skills/mem0-memory/scripts/crud/search-memories.py \
  --query "patterns outcomes" \
  --user-id "project-decisions" \
  --limit 100

2. Aggregate Results

Group patterns by category, then by outcome:

{
  "pagination": {
    "successes": [...],
    "failures": [...]
  },
  "authentication": {
    "successes": [...],
    "failures": [...]
  }
}

3. Calculate Statistics

For each pattern:

• Count occurrences across projects
• Calculate success rate: successes / (successes + failures)
• Note which projects contributed

4. Display Output

PAGINATION
─────────────────────────────────────────────────────────────
  ✅ Cursor-based pagination (3 projects, always worked)
     "Scales well for large datasets"

  ❌ Offset pagination (failed in 2 projects)
     "Caused timeouts on tables with 1M+ rows"
     💡 Lesson: Use cursor-based for large datasets

AUTHENTICATION
─────────────────────────────────────────────────────────────
  ✅ JWT + httpOnly refresh tokens (4 projects)
     "Secure and scalable for web apps"

  ⚠️ Session-based auth (mixed: 1 success, 1 failure)
     "Works but scaling issues in high-traffic scenarios"

───────────────────────────────────────────────────────────────
📊 Summary: 8 patterns | 5 ✅ successes | 3 ❌ anti-patterns
💡 Use `/remember --success` or `/remember --failed` to add more

Start building it with:
• /remember --success "Pattern that worked well"
• /remember --failed "Pattern that caused problems"

Your patterns will be tracked across all projects and help
Claude warn you before repeating past mistakes.

Proactive Integration
