What problem does it solve?

This Skill consolidates best practices for creating Claude Code slash commands, including frontmatter structure, dynamic arguments, file references, and plugin patterns. It helps teams design scalable, discoverable, and safe commands.

Core Features & Use Cases

  • Frontmatter-driven design: Use YAML frontmatter to configure command behavior, discovery, and tooling.
  • Dynamic arguments & references: Support for $ARGUMENTS, $1, @file references, and bash execution within commands.
  • Plugin-aware patterns: Organization, root references, and multi-script templates for plugin ecosystems.
