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 the skill. ## Core Features & Use Cases - Specification Guidance: Documents the required name and description frontmatter fields, character limits, and formatting rules for valid skills. - Progressive Disclosure Architecture: Explains the 3-level loading system (metadata, SKILL.md body, referenced files) so skills scale without context bloat. - Ready-to-Use Templates: Provides basic, intermediate, and advanced skill templates plus validation checklists and real-world examples. - Use Case: A developer wants to build a custom skill that generates API documentation. This skill walks them through creating the directory, writing compliant frontmatter, structuring instructions, and adding scripts and resources. ## Quick Start Ask Claude to create a new skill called my-first-skill with proper frontmatter and a quick start section.
