Hello World Skill

This is a simple example skill that demonstrates the fundamental structure and components of a Claude Skill.

Overview

The Hello World skill provides a minimal working example of:

• YAML frontmatter configuration
• Markdown-based instructions
• Bundled Python scripts
• Reference documentation
• Clear usage patterns

Usage

This skill can be triggered with queries like:

• "Run the hello world skill"
• "Show me a greeting"
• "Test the example skill"

Basic Greeting

To generate a simple greeting, use the bundled script:

python scripts/greet.py

Custom Greetings

The script supports custom names:

python scripts/greet.py --name "Alice"

Bundled Resources

Scripts

scripts/greet.py - A simple Python script that generates customizable greetings.

Features:

• Default greeting message
• Custom name support via command-line argument
• Clean, documented code

Usage examples:

# Basic greeting
python scripts/greet.py

# Custom name
python scripts/greet.py --name "Bob"

# Help
python scripts/greet.py --help

References

references/greeting_guidelines.md - Best practices for creating effective greetings.

This reference is loaded only when needed, demonstrating progressive disclosure:

• Keeps main SKILL.md lean
• Provides detailed information on demand
• Reduces context window usage

Best Practices Demonstrated

This skill showcases several Claude Skill best practices:

1. Concise frontmatter - Only required fields (name, description)
2. Clear structure - Well-organized sections with purpose
3. Executable resources - Scripts for deterministic tasks
4. Progressive disclosure - References loaded as needed
5. Practical examples - Real usage patterns shown

When to Use This Pattern

Use this skill structure as a template when creating skills that:

• Have deterministic, repeatable operations
• Benefit from executable scripts
• Need reference documentation
• Should minimize context usage

Extending This Skill

To build upon this example:

1. Replace greet.py with your own scripts
2. Update greeting_guidelines.md with domain-specific knowledge
3. Modify frontmatter description to match your use case
4. Add assets if needed for output generation

Remember: Only include information Claude doesn't already know. Keep it concise!
