> A curated list of awesome Claude Skills, resources, and tools for customizing Claude AI workflows

**Claude Skills** teach Claude how to **perform tasks in a repeatable way**

They are specialized folders containing instructions, scripts, and resources that Claude dynamically discovers and loads when relevant to tasks.

### How Skills Work

Skills employ a **progressive disclosure architecture** for efficiency:

1. **Metadata loading** (~100 tokens): Claude scans available Skills to identify relevant matches
2. **Full instructions** (<5k tokens): Load when Claude determines the Skill applies
3. **Bundled resources**: Files and executable code load only as needed

This design allows multiple Skills to remain available without overwhelming Claude's context window.

## 🚀 Getting Started

### Claude.ai Web Interface

1. Go to [Settings > Capabilities](https://claude.ai/settings/capabilities)
2. Enable Skills toggle
3. Browse available skills or upload custom skills
4. **For Team/Enterprise**: Admin must enable Skills organization-wide first

### Claude Code CLI

```bash
# Install skills from marketplace
/plugin marketplace add anthropics/skills

# Or install from local directory
/plugin add /path/to/skill-directory
```

### Claude API

Skills are accessible via the `/v1/skills` API endpoint. See the [Skills API documentation](https://platform.claude.com/docs/en/api/beta/skills) for detailed integration examples.

```python
import anthropic

client = anthropic.Client(api_key="your-api-key")
# See API docs for full implementation details
```

## ✏️ Creating Your First Skill

<details>
<summary><strong>Step-by-Step Guide</strong></summary>

### Method 1: Use skill-creator (Recommended)

The easiest way to create a skill is to use the built-in `skill-creator`:

1. Enable the skill-creator skill in Claude
2. Ask Claude: "Use the skill-creator to help me build a skill for [your task]"
3. Answer the interactive questions about your workflow
4. Claude generates the complete skill structure for you

### Method 2: Manual Creation

1. **Create folder structure**:

   ```
   my-skill/
   ├── SKILL.md          # Main skill file with frontmatter
   ├── scripts/          # Optional executable scripts
   │   └── helper.py
   └── resources/        # Optional supporting files
       └── template.json
   ```

2. **Create SKILL.md with frontmatter**:

   ```yaml
   ---
   name: my-skill
   description: Brief description for skill discovery (keep concise)
   ---

   # Detailed Instructions

   Claude will read these instructions when the skill is activated.

   ## Usage
   Explain how to use this skill...

   ## Examples
   Provide clear examples...
   ```

3. **Add executable scripts** (optional):

   - Python, JavaScript, or other scripts Claude can execute
   - Reference them in your SKILL.md instructions

4. **Test locally**:

   - Install the skill in Claude Code or Claude Desktop
   - Test with relevant tasks
   - Iterate and refine

5. **Share**:
   - Publish to GitHub
   - Submit to this awesome list via PR
   - Share with your team via git repos or internal distribution

### Best Practices

- **Keep descriptions concise** - The frontmatter description is used for skill discovery
- **Use clear, actionable instructions** - Write instructions as if for a human collaborator
- **Include examples** - Show specific exa
