1. Understand the goal - Ask what task the skill should accomplish
2. Identify triggers - Determine natural phrases users would say
3. Choose template - Select from 8 templates based on complexity
4. Generate structure - Create SKILL.md and supporting files
5. Validate - Run 7-point validation
6. Iterate - Improve until score >= 80

Skill Best Practices (Quick Reference)

Description Quality

• Include 3-5 trigger phrases users naturally say
• Be specific about scenarios (e.g., "when deploying to AWS")
• Avoid generic descriptions

Content Guidelines

• Use imperative form ("Run tests" not "You should run tests")
• Keep SKILL.md under 500 lines
• Move detailed docs to references/ folder
• Include concrete examples with expected outputs

Structure Requirements

my-skill/
├── SKILL.md              # Main skill (required)
├── references/           # Extended documentation
│   └── detailed-guide.md
└── scripts/              # Automation scripts
    └── helper.py

Validation Criteria (7 Points)

1. Structure - Correct files and directories exist
2. Frontmatter - Valid name, description, optional context
3. Description - Contains trigger phrases and scenarios
4. Content - Imperative form, examples, appropriate length
5. Progressive Disclosure - SKILL.md lean, details in references
6. Resources - Referenced files exist, scripts are executable
7. Cross-Platform - agentskills.io compatibility (optional)
