SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyyaml, and includes scripts (resource) and references (resource) components.

What problem does it solve? Building a well-structured skill from scratch requires knowing the SKILL.md format, frontmatter rules, and packaging conventions, which is error-prone without guidance and tooling. ## Core Features & Use Cases - Skill Scaffolding: Run init_skill.py to generate a complete 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, and description rules, then package_skill.py to produce a distributable .skill file. - Design Guidance: Follow built-in principles on progressive disclosure, degrees of freedom, and reference patterns for workflows and output formats. - Use Case: When asked to build a new pdf-editor skill, initialize the directory, implement a rotation script, write the SKILL.md instructions, validate, and package it into a .skill file for distribution. ## Quick Start Create a new skill named pdf-editor using the skill-creator scripts and then package it into a distributable .skill file.

Frequently Asked Questions about skill-creator

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a new Claude skill from scratch?▼

Run init_skill.py with a hyphen-case skill name and output path to generate a skill directory containing a SKILL.md template plus example scripts, references, and assets folders. Then edit the SKILL.md frontmatter and body, and customize or delete the example files.

What is the required structure of a SKILL.md file?▼

A SKILL.md requires YAML frontmatter with name and description fields, followed by a Markdown body with instructions. The name must be hyphen-case and the description must explain what the skill does and when to use it.

How do I package a skill into a .skill file?▼

Run package_skill.py with the path to your skill folder and an optional output directory. The script validates the skill first, then creates a zip-based .skill file named after the skill folder if validation passes.

Why does skill validation fail on my SKILL.md?▼

Validation fails when frontmatter is missing or malformed, the name is not hyphen-case or exceeds 64 characters, the description contains angle brackets or exceeds 1024 characters, or unexpected frontmatter keys are present.

When should I use scripts versus references in a skill?▼

Use scripts for deterministic, repeatedly rewritten code like file conversions, and references for documentation Claude should load on demand such as schemas or workflow guides. Keep SKILL.md lean and move detailed material into reference files.
