# Skill Creator

This skill provides guidance for creating effective skills.

## About Skills

Skills are modular, self-contained packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools.

### What Skills Provide

1. Specialized workflows - Multi-step procedures for specific domains
2. Tool integrations - Instructions for working with specific file formats or APIs
3. Domain expertise - Company-specific knowledge, schemas, business logic
4. Bundled resources - Scripts, references, and assets for complex tasks

## Skill Structure

```

│   │   ├── name: (required)
│   │   └── description: (required)
│   └── Markdown instructions (required)
└── Bundled Resources (optional)
    ├── scripts/          - Executable code
    ├── references/       - Documentation
    └── assets/           - Files used in output
```

## Core Principles

### Concise is Key

Only add context Claude doesn't already have. Challenge each piece of information: "Does Claude really need this explanation?"

### Set Appropriate Degrees of Freedom

- **High freedom**: Use when multiple approaches are valid
- **Medium freedom**: Use when a preferred pattern exists
- **Low freedom**: Use when operations are fragile and error-prone

## Skill Creation Process

1. Understand the skill with concrete examples
2. Plan reusable skill contents (scripts, references, assets)
3. Initialize the skill (run init_skill.py)
4. Edit the skill (implement resources and write SKILL.md)
5. Package the skill (run package_skill.py)
6. Iterate based on real usage
