What problem does it solve? Building custom Claude Code Skills requires knowing the exact SKILL.md format, YAML frontmatter rules, and directory conventions, and mistakes in any of these prevent Claude from discovering or loading your skill. ## Core Features & Use Cases - Specification Reference: Provides the complete SKILL.md specification including required name and description fields, character limits, and YAML formatting rules. - Progressive Disclosure Guidance: Explains the 3-level architecture (metadata, SKILL.md body, referenced files) so skills scale without context bloat. - Ready-to-Use Templates: Includes basic, intermediate, and advanced skill templates plus real-world examples for documentation and code generation skills. - Use Case: You want to build a custom skill that generates API documentation for your team. Use this Skill to scaffold the directory, write a compliant SKILL.md with proper frontmatter, and validate it against the checklist before publishing. ## Quick Start Ask Claude to create a new skill called 'api-docs-generator' with proper frontmatter and a quick start section using the Skill Builder templates.
