# Test E2E Skill

This skill is used for end-to-end testing of the Skills system.

## Instructions

When the user asks you to create a test file:
1. Create a file with the requested name
2. Write the requested content
3. Confirm the file was created successfully

## Output Format

Always respond with:
- File path
- File content
- Success message
