creating-claude-rules

name	creating-claude-rules
description	Use when creating or fixing .claude/rules/ files - provides correct paths frontmatter (not globs), glob patterns, and avoids Cursor-specific fields like alwaysApply
metadata	{"author":"AgentWorkforce"}

Overview

Rules in .claude/rules/ are modular instructions scoped to specific files via glob patterns. They load automatically with same priority as CLAUDE.md.

When to Use

• Creating new rules in .claude/rules/
• Fixing rules that use wrong frontmatter (globs instead of paths)
• Migrating Cursor rules to Claude format
• Organizing project-specific conventions

Quick Reference

Field	Claude	Cursor
Path patterns	paths	globs
Always apply	Omit paths	alwaysApply: true
Description	Not documented	description

Frontmatter

Path-Scoped Rules

---
paths:
  - "src/api/**/*.ts"
  - "tests/**/*.test.ts"
---

Global Rules

# TypeScript Conventions

Use .js extensions in imports.

Common Mistakes

```yaml

# ❌ WRONG - globs is Cursor format
---
globs:
  - "**/*.ts"
---

# ✅ CORRECT - Claude uses paths
---
paths:
  - "**/*.ts"
---

Directory Structure

```

├── testing.md          # Path-scoped or global
├── typescript.md

Glob Patterns

Pattern	Matches
**/*.ts	All .ts files anywhere

**/*.{ts,tsx}	.ts and .tsx files
{src,lib}/**/*.ts	.ts in src/ or lib/
