What problem does it solve? Building a well-structured skill requires knowing the SKILL.md frontmatter format, directory conventions, and packaging rules, which is error-prone when done manually. This Skill guides the full lifecycle of creating skills that extend Claude with specialized workflows and tools. ## Core Features & Use Cases - Skill Initialization: Run init_skill.py to scaffold a new skill directory with a SKILL.md template and example scripts, references, and assets folders. - Validation and Packaging: Use quick_validate.py to check frontmatter, naming conventions, and description quality, then package_skill.py to produce a distributable .skill file. - Design Guidance: Apply progressive disclosure principles and proven workflow and output patterns from the bundled reference files. - Use Case: When you want to build a new skill for PDF processing, use this Skill to scaffold the directory, write a compliant SKILL.md, validate it, and package it into a shareable .skill file. ## Quick Start Create a new skill called pdf-rotator using the skill-creator, then validate and package it into a .skill file.
