What problem does it solve? Writing a high-quality SKILL.md requires knowing the Agent Skills specification, avoiding duplication with existing skills, and passing structural validation — this Skill codifies that entire workflow into a repeatable procedure. ## Core Features & Use Cases - Create new skills: Researches the domain via web and GitHub search, designs the required section structure, and writes a validated SKILL.md with correct frontmatter. - Audit existing skills: Checks a skill against a quality checklist covering frontmatter, trigger phrases, section order, reference integrity, and line limits, then produces a gap report and applies fixes. - Refactor and validate: Restructures non-compliant skills, runs a bash validation script for name/folder match and required sections, and optionally creates a Claude Code companion file. - Use Case: You want to add a new skill for Terraform workflows to your Copilot skills collection — this Skill inventories existing skills, researches comparable SKILL.md files on GitHub, writes the new skill, and validates it end to end. ## Quick Start Ask the agent to create a new skill for your chosen domain using the skill-builder workflow and validate it against the quality checklist.
