SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill guides the creation of Claude Code slash commands, including file formats, YAML frontmatter, dynamic arguments, and best practices for reliable, scalable command development.

Core Features & Use Cases

  • Command file patterns and frontmatter fields (description, allowed-tools, model, argument-hint)
  • Dynamic arguments ($ARGUMENTS, $1, $2, ...)
  • File references and Bash execution syntax
  • Command organization, namespaces, and pattern examples
  • Validation patterns and error handling guidance

Quick Start

Create a minimal command file under commands/, with optional frontmatter to constrain tools and model. Validate the command with the command-development references and test basic invocation via Claude Code.
