# Command Development

For anyone who keeps retyping the same prompt to Claude Code

## What this does

You keep sending Claude Code the same instructions and want to type something short instead. This helps you build your own slash commands, including ones that take details you fill in each time, point at particular files, or ask you a quick question before they run. Reach for it when a prompt has become a habit worth saving, or when the commands you already have need sorting out.

### Top 3 things it does for you

- Create a slash command for a prompt I keep writing out
- Add arguments so one command handles many variations
- Point a command at the files it needs

## About Command Development

This skill covers building custom slash commands for Claude Code, from your first simple command to ones that behave differently depending on how you call them. It is meant for moments like wanting to add a command, define the arguments it accepts, or make an existing command more flexible.

Alongside the basics of command structure, it walks through the frontmatter fields a command can set, dynamic arguments that pull in details when you run the command, referencing files from within a command, and running bash inside one. For commands that need something from you before they act, it also covers ways to ask the user a question along the way.

It closes with guidance on organizing a growing collection of commands and on the habits that make up good command development practice.

## Questions

### Is Command Development safe to install?

AIR scanned this exact version of Command Development and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit cc898dc3692f, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/command-development.

### How do I install Command Development?

Open https://airmarket.ai/app/command-development on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/anthropics/claude-code/tree/cc898dc3692fb583f36ab327942aad20b7d3dbd0/plugins/plugin-dev/skills/command-development. Install from that link, not the branch.
