Command Development

anthropics/claude-codeOfficial

If you're building custom slash commands for Claude Code, this is the reference you need. It breaks down how to structure commands as Markdown files, configure them with YAML frontmatter, and use dynamic arguments and bash execution to pull in context. The skill covers command organization and namespacing, which matters once you have more than a handful of commands floating around. Note that it includes shell command directives, so review what's actually being executed before you install. Think of this as the manual for turning your repetitive prompts into reusable, parameterized commands instead of copy-pasting the same instructions every session.
