Rules Optimizer

Create and optimize .claude/rules/*.md files for effective AI guidance.

Best Practices

File Structure

Rule File Format

Copy---
paths: "**/*.{ts,tsx}" # Glob pattern (quoted)
---

# [Topic] Rules

## [Category]

[Rule statement]

\`\`\`typescript
// ❌ BAD
[anti-pattern]

// ✅ GOOD
[correct pattern]
\`\`\`

Content Guidelines

1. One topic per file — keep focused
2. 150-200 lines ideal — enough for examples, not overwhelming
3. Include examples — 1 BAD/GOOD pair per rule that needs clarity
4. Skip obvious rules — focus on what AI gets wrong
5. No "why" explanations — just the rule and example
6. Use tables for mappings (e.g., v3→v4 migrations)

Path Patterns

What to Include

• ❌ Anti-patterns AI commonly generates
• ✅ Correct patterns with minimal example
• Migration mappings (old → new)
• Framework-specific conventions

What to Exclude

• Self-evident rules (use semicolons, etc.)
• Long explanations of "why"
• Multiple examples for same rule
• Style preferences (let linters handle)

Workflow

1. Read existing rule file
2. Identify: redundancy, missing examples, excessive length
3. Compress to essentials with 1 example per rule
4. Ensure paths pattern is appropriate
5. Output optimized version
