What problem does it solve? Writing a well-structured Claude Code plugin skill requires knowing the full frontmatter field catalog, procedure conventions, and quality standards. This Skill turns a rough skill concept into a complete, review-ready SKILL.md design document that follows the official spec and MOAT quality dimensions. ## Core Features & Use Cases - Full frontmatter drafting: Generates YAML frontmatter using all official fields (name, description, argument-hint, allowed-tools, model, hooks, and more) with least-privilege tool selection. - Structured procedure design: Produces 5-10 numbered steps with action verbs, inputs, outputs, and evidence tags, plus quality criteria, anti-patterns, and edge cases. - MOAT quality validation: Scores the design against Completeness, Accuracy, Actionability, and Maintainability before presentation. - Use Case: You are building a devops plugin and need a new lint-dockerfile skill. Provide the concept, and this Skill outputs a complete SKILL.md specification including trigger phrases, a guiding principle quote, testable quality criteria, and documented edge cases. ## Quick Start Ask the AI to design a skill named lint-dockerfile for your plugin, including frontmatter, procedure steps, quality criteria, anti-patterns, and edge cases.
