# Skill Creator

Create and manage Claude Code skills with proper structure and conventions.

## Skill Anatomy

Skills live in `.claude/skills/<skill-name>/` and have two forms:

### Simple Skills (Documentation Only)

```
my-skill/
└── SKILL.md
```

### Complex Skills (With Scripts)

```
my-automation/
├── SKILL.md
├── run.py
├── list.py
└── cleanup.py
```

## SKILL.md Format

All skills require a `SKILL.md` with YAML frontmatter:

```yaml
---
name: skill-name
description: Brief description. Use when [trigger conditions]...
---

# Skill Title

[Instructions and documentation]
```

### Required Frontmatter Fields

**name** (required)

- Maximum 64 characters
- Lowercase letters, numbers, and hyphens only
- Cannot contain XML tags
- Cannot contain reserved words: "anthropic", "claude"

**description** (required)

- Maximum 1024 characters
- Must be non-empty
- Cannot contain XML tags
- Should describe what the skill does AND when to use it

### Optional Frontmatter Fields

```yaml
---
name: my-skill
description: Does X. Use when Y...
license: MIT
allowed-tools:
  - Bash
  - Read
metadata:
  author: your-name
  version: 1.0.0
---
```

## Progressive Disclosure

Skills load content in stages to minimize context usage:

| Level | When Loaded | Token Cost | Content |
|-------|-------------|------------|---------|
| **Level 1: Metadata** | Always (startup) | ~100 tokens | `name` and `description` from frontmatter |
