What problem does it solve?

Automates the creation and maintenance of Claude Code skills, including YAML frontmatter validation, resource discovery, and automatic invocation triggers.

Core Features & Use Cases

  • Structured SKILL.md frontmatter enforcement
  • Auto-discovery of resources (scripts/references/assets)
  • Templates and scaffolding for new skills
  • Validation and enhancement workflows for quality
  • Clear separation between skills vs agents

Quick Start

Create a new skill folder, copy the templates, add resources, and run validate/enhance commands.

FAQPage Schema
How do I automate Claude Code skill creation with YAML validation?

Automating skill creation involves using templates and scripts to enforce YAML frontmatter compliance, auto-discover resources like scripts and references, and validate schema requirements such as gerund naming, comma-separated allowed-tools, and proper baseDir references. This Skill handles the full lifecycle—scaffolding, validation, and enhancement—so you maintain consistency across skills without manual frontmatter editing.

What YAML frontmatter fields must I configure for Claude Code skills?

Claude Code skills require structured YAML frontmatter including description, allowed-tools (comma-separated), and resource paths. This Skill enforces schema compliance by validating that the model field is prohibited, gerund naming conventions are followed, and baseDir references point to executable scripts correctly, catching errors before deployment.

Can I use PyYAML to build and validate skill templates?

Yes. This Skill uses PyYAML as a dependency to parse, validate, and generate YAML frontmatter for skills. It automates template scaffolding, resource discovery, and frontmatter adjustment, allowing you to create new skills with correct structure and enforce validation rules across your skill architecture.

How do I design skill architectures with automatic invocation?

This Skill automates the design and enhancement of auto-invoked skill architectures by managing YAML configuration, resource organization into scripts and references, and progressive disclosure of capabilities. It handles lifecycle operations—creating, updating, validating, and standardizing skills—ensuring functional and technical requirements are met consistently.

What's the difference between building skills versus agents in Claude Code?

Skills are reusable, auto-invoked tool components with structured YAML metadata and resource organization, while agents are broader orchestration logic. This Skill focuses on the skill-creation lifecycle: scaffolding, validation, and schema compliance for skills specifically, ensuring clear separation between the two architectural patterns.

Does this work for validating existing skill resources and enhancing them?

Yes. This Skill validates and enhances existing skills by auto-discovering resources, adjusting YAML frontmatter fields, standardizing allowed-tools declarations, and ensuring schema compliance. It works across the full lifecycle—creation, modification, and quality assurance—without rebuilding skills from scratch.
