---
name: skill-name
description: Brief description of what this skill does and when to use it

YAML Frontmatter Fields

File Structure

skill-name/
├── SKILL.md              # Required - overview and navigation
├── reference.md          # Detailed docs - loaded when needed
├── examples.md           # Usage examples - loaded when needed
└── scripts/
    └── helper.sh         # Utility script - executed, not loaded

Best Practices

• Keep SKILL.md under 250 lines - Use progressive disclosure
• Write specific descriptions - Include trigger terms users would naturally use
• Link supporting files - From SKILL.md using markdown links
• Validate structure - Check YAML syntax and file organization
• No .py or .sh files in root - Place scripts in scripts/ or within the skill directory. Never create one-off scripts in the repository root.

See naming.md for naming conventions and templates.md for ready-to-use templates.
