概要
Claude Skill Builder is an essential utility for developers looking to extend Claude's capabilities through custom skills. It provides a standardized framework for authoring SKILL.md files, ensuring proper YAML frontmatter for discovery and implementing a three-level progressive disclosure architecture. This architecture allows users to maintain a library of over 100 skills without hitting context limits, as Claude only loads detailed instructions when a skill is actively triggered. Whether building personal productivity shortcuts or shared project-specific workflows, this tool ensures your skills are performant, discoverable, and structurally sound.
