This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.

TL;DR

Slash commands in Claude Code are Markdown files that provide instructions to Claude when invoked via a command prefix, enabling structured, reusable, and context-aware interactions.

What Is It

A Markdown file that becomes instructions for Claude when invoked via `/command-name`
Used to define actions or tasks that Claude can perform in response to user input
Structured with YAML frontmatter and dynamic arguments for flexibility

Key Features

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

How to Use

1.Create a new Markdown file in the appropriate directory (project, personal, or plugin)
2.Use YAML frontmatter to define command metadata such as name, description, and arguments
3.Include dynamic arguments and file references to enable context-aware behavior
4.Test commands by invoking them via `/command-name` in the appropriate context
5.Organize commands logically by scope (project, personal, plugin) to maintain clarity and reusability

Guardrails & Gotchas

Avoid sending messages to users instead of instructing Claude directly
Do not use commands to send messages to users (e.g., 'This command will review your code')
Ensure commands are self-contained and do not rely on external user input beyond what's defined in the command
Be cautious with file references and dynamic arguments that could lead to unintended execution or security risks
Maintain consistent naming and structure across commands to avoid confusion and improve maintainability
