mk:skill-creator — Skill Scaffolding & Validation

What This Skill Does

Create new skills with proper structure, compliance, and registration. Enforces the mk: prefix, sub-agents.md structure, and Anthropic context engineering principles.

When to Use

• User asks to "create a skill", "build a new skill", "make a skill for [X]"
• Converting an external skill for adoption in MeowKit
• Scaffolding a skill from a workflow pattern
• Explicit: /mk:skill-creator [NAME] [description]

Do NOT invoke: When the user just wants to edit an existing skill's content — this is for creation and scaffolding only.

Core Capabilities

• Scaffolding: scripts/init-skill.py creates directory + template SKILL.md with TODO markers
• Validation: scripts/validate-skill.py checks compliance against 8-point checklist
• Content guidance: References cover required sections, trigger-condition descriptions, gotcha writing, filesystem patterns, and 9-type taxonomy
• Registration: Adds attribution row to SKILLS_ATTRIBUTION.md

Example Prompt

Create a new skill called mk:database that generates PostgreSQL schema migrations from TypeScript entity definitions. It should validate schemas against naming conventions and produce a migration plan.

Process

1. Gather intent — what should the skill do? When should it trigger? What output format?
2. Scaffold — run init-skill.py mk:NAME --path .claude/skills to create directory + template
3. Fill content — Claude completes each TODO section in the generated template
4. Add references/ — if skill body would exceed ~500 lines, split into reference files
5. Security boundaries — load mk:skill-template-secure for trust model if skill processes untrusted input
6. Validate — run validate-skill.py to check 8-point compliance
7. Fix failures — if score < 7/8, fix failing items
8. Register — add row to SKILLS_ATTRIBUTION.md
9. Report — output creation summary with compliance details
