について
このスキルは、開発者が`.claude/rules/`ファイルを作成・修正する際に、正しいフロントマター構文(特に`globs`の代わりに`paths`を使用し、Cursor固有のフィールドを避けること)を提供することで支援します。プロジェクト固有の規約を整理したり、プラットフォーム間でルールを移行する場合に有用です。このスキルは、ファイルスコープ指定のためのglobパターンを用いた適切なフォーマットを保証します。

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 (
globsinstead ofpaths) - 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/ |

evaluating-llms-harness
テストThis Claude Skill runs the lm-evaluation-harness to benchmark LLMs across 60+ standardized academic tasks like MMLU and GSM8K. It's designed for developers to compare model quality, track training progress, or report academic results. The tool supports various backends including HuggingFace and vLLM models.
sglang
メタSGLang is a high-performance LLM serving framework that specializes in fast, structured generation for JSON, regex, and agentic workflows using its RadixAttention prefix caching. It delivers significantly faster inference, especially for tasks with repeated prefixes, making it ideal for complex, structured outputs and multi-turn conversations. Choose SGLang over alternatives like vLLM when you need constrained decoding or are building applications with extensive prefix sharing.
langchain
メタLangChain is a framework for building LLM applications using agents, chains, and RAG pipelines. It supports multiple LLM providers, offers 500+ integrations, and includes features like tool calling and memory management. Use it for rapid prototyping and deploying production systems like chatbots, autonomous agents, and question-answering services.
cloudflare-turnstile
メタThis skill provides comprehensive guidance for implementing Cloudflare Turnstile as a CAPTCHA-alternative bot protection system. It covers integration for forms, login pages, API endpoints, and frameworks like React/Next.js/Hono, while handling invisible challenges that maintain user experience. Use it when migrating from reCAPTCHA, debugging error codes, or implementing token validation and E2E tests.
