Excerpt

Command Development for Claude Code

Note: The .claude/commands/ directory is a legacy format. For new skills, use the .claude/skills/<name>/SKILL.md directory format. Both are loaded identically — the only difference is file layout. See the skill-development skill for the preferred format.

Overview

Slash commands are frequently-used prompts defined as Markdown files that Claude executes during interactive sessions. Understanding command structure, frontmatter options, and dynamic features enables creating powerful, reusable workflows.

Key concepts:

Markdown file format for commands
YAML frontmatter for configuration
Dynamic arguments and file references
Bash execution for context
Command organization and namespacing

This is the opening of the README. Read the full README on GitHub.
