SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Reduce friction and inconsistency when creating, organizing, and validating Claude Code plugin skills by providing a clear, repeatable authoring process and checklist that ensures discoverability and efficient context loading.

Core Features & Use Cases

  • Authoring guidance: Define SKILL.md frontmatter with exact name and third-person trigger description, and write the body in imperative form.
  • Progressive disclosure & organization: Recommend moving large or detailed content to references/, place deterministic utilities in scripts/, and store output templates in assets/.
  • Validation and testing: Provide a checklist for structure, trigger phrases, style, referenced resources, and testing workflows to verify the skill triggers and functions as intended.
  • Use Case: When adding a new "hook-development" skill to a plugin, follow the process to create SKILL.md, reference patterns in references/, add test utilities in scripts/, and run validation to ensure correct triggers and progressive disclosure.

Quick Start

Create a new skill directory under skills/, add SKILL.md with YAML frontmatter including name and a third-person description with exact trigger phrases, write the body in imperative form, and place detailed documentation in references/.

FAQPage Schema
How do I create a Claude Code skill and structure its SKILL.md metadata?

Progressive disclosure in skill development keeps the main SKILL.md concise by moving large or detailed content to references/, placing deterministic utilities in scripts/, and storing output templates in assets/. This organization ensures efficient context loading and discoverability when Claude triggers the skill.

What are the validation steps for Claude Code plugin skills?

Validating Claude Code plugin skills involves checking the SKILL.md structure, verifying exact trigger phrases in the description, ensuring imperative writing style, confirming referenced resources exist, and testing workflows to guarantee the skill triggers and functions as intended.

How do trigger phrases work in SKILL.md frontmatter for skill creation?

Trigger phrases in SKILL.md frontmatter are defined within a third-person description in the YAML metadata. These exact phrases determine when Claude activates the skill, requiring careful authoring and testing to ensure the plugin skill responds correctly to user intent.

When should I move documentation to references/ during skill development?

You should move documentation to references/ during skill development when content is too large or detailed for the main SKILL.md body. This progressive disclosure approach maintains efficient context loading while keeping bundled resources accessible for deeper task execution.

Does Claude Code skill creation require specific dependencies or scripts?

Claude Code skill creation does not require specific dependencies, but deterministic utilities can be placed in scripts/ and output templates in assets/. The core requirement is a valid SKILL.md with YAML frontmatter, while additional components follow progressive disclosure for organization.
