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

📚 Best Practices: PAGINATION ═══════════════════════════════════════════════════════════════

✅ Cursor-based pagination (3 projects, always worked) "Scales well for large datasets" Projects: project-a, project-b, project-c

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

Pattern Confidence Indicators

Icon Meaning

✅ Strong success (3+ projects, 100% success rate)

✓ Moderate success (1-2 projects or some failures)

⚠️ Mixed results (both successes and failures)

❌ Anti-pattern (only failures)

🔴 Strong anti-pattern (3+ projects, all failed)

Empty Library

📚 Your Best Practices Library is empty

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
