What problem does it solve? Designing a well-structured Skill requires knowing the SKILL.md format, frontmatter rules, naming conventions, and packaging steps. This Skill guides the entire lifecycle of creating or updating AgentSkills so they are discoverable, concise, and correctly packaged. ## Core Features & Use Cases - Skill Scaffolding: Run init_skill.py to generate a new skill directory with a SKILL.md template and optional scripts/, references/, and assets/ directories. - Design Guidance: Apply progressive disclosure principles, naming conventions, and frontmatter best practices when writing SKILL.md instructions. - Validation & Packaging: Use package_skill.py to validate frontmatter, naming, and structure, then produce a distributable .skill zip file. - Use Case: When asked to build a new pdf-editor skill, follow the six-step process to gather requirements, plan reusable resources, initialize the directory, write instructions, and package the result. ## Quick Start Create a new skill named pdf-editor with scripts and references directories, then package it into a distributable .skill file.
