Marketplace creating-claude-rules

Use when creating or fixing .claude/rules/ files - provides correct paths frontmatter (not globs), glob patterns, and avoids Cursor-specific fields like alwaysApply

Creating Claude Rules

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"
---

Or single pattern:

---
paths: src/**/*.{ts,tsx}
---

Global Rules

Omit frontmatter entirely - applies to all files:

# TypeScript Conventions

Use .js extensions in imports.

Common Mistakes

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

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

# ❌ WRONG - alwaysApply is Cursor-only
---
alwaysApply: true
---

# ✅ CORRECT - just omit paths for global rules
# (no frontmatter needed)

# ❌ WRONG - unquoted patterns
---
paths:
  - **/*.ts
---

# ✅ CORRECT - quote glob patterns
---
paths:
  - "**/*.ts"
---

Directory Structure

.claude/rules/
├── testing.md          # Path-scoped or global
├── typescript.md
└── frontend/           # Subdirectories supported
    └── react.md

Files discovered recursively. Use subdirectories to organize.

Glob Patterns

Pattern	Matches
`*/.ts`	All .ts files anywhere
`src/*/`	Everything under src/
`*.md`	Markdown in root only
`*/.{ts,tsx}`	.ts and .tsx files
`{src,lib}/*/.ts`	.ts in src/ or lib/
