What problem does it solve? Writing effective skills for AI agents requires knowing the right structure, frontmatter rules, and resource organization, and doing it by hand leads to invalid or bloated skills that fail to trigger correctly. ## Core Features & Use Cases - Guided Skill Authoring: Provides design principles for SKILL.md frontmatter, progressive disclosure, and degrees of freedom so skills stay concise and trigger reliably. - Scaffolding and Packaging Scripts: Includes init_skill.py to generate a template skill directory and package_skill.py to validate and bundle a skill into a distributable .skill file. - Reference Patterns: Ships workflow and output-pattern references covering sequential steps, conditional logic, templates, and examples. - Use Case: You want to build a pdf-editor skill. Run the initializer to scaffold the directory, follow the guidance to write SKILL.md and add a rotate script, then package it into a validated .skill file for distribution. ## Quick Start Ask the agent to create a new skill named pdf-editor that rotates PDF pages and package it for distribution.
