Skill Creator

Create high-quality Claude Code skills, hooks, MCP configurations, and custom agents.

About Skills

Skills are modular packages that extend Claude’s capabilities with:

• Specialized workflows – Multi-step procedures for specific domains
• Tool integrations – Instructions for file formats or APIs
• Domain expertise – Company-specific knowledge, schemas, business logic
• Bundled resources – Scripts, references, and assets

Think of skills as “onboarding guides” that transform Claude from general-purpose to specialized.

Quick Start: Create a Skill

1. Create directory: ~/.claude/skills/your-skill-name/
2. Create SKILL.md with frontmatter and instructions
3. Skill is immediately available via /your-skill-name

Minimal SKILL.md:

---
name: your-skill-name
description: What it does. Use when [specific triggers].
---

# Your Skill Name

Instructions for Claude to follow.

Skill Creation Process

1. Understand – Gather concrete examples of skill usage
2. Plan – Identify reusable scripts, references, assets
3. Initialize – python scripts/init_skill.py my-skill --path ~/.claude/skills/
4. Edit – Implement resources, write SKILL.md
5. Validate – python scripts/quick_validate.py path/to/skill
6. Iterate – Test with real usage, refine based on feedback

Quality Checklist

Before deploying a skill, verify:

• name: lowercase, hyphens, max 64 chars
• description: includes WHAT it does and WHEN to use it
• SKILL.md body under 500 lines
• Large content split into references/
• No time-sensitive information
• Tested with real usage scenarios

Common Patterns

Skill with references:

skill-name/
├── SKILL.md
└── references/
    ├── api.md
    └── examples.md

Skill with scripts:

skill-name/
├── SKILL.md
└── scripts/
    └── helper.py

Skill with hooks:

Add to settings.json:

{
  "hooks": {
    "PostToolUse": [{
      "matcher": "Write",
      "hooks": [{"type": "command", "command": "./format.sh"}]
    }]
  }
}
