# Create CLI

Decide how your command-line tool should behave before you build it

## What this does

You are building a command-line tool and the small decisions - what the flags are called, what an error says, what gets printed - add up fast. This covers the design of those: args, flags, help, output, errors, config and dry-run. Reach for it before you start writing the tool.

### Top 3 things it does for you

- Work out the arguments and flags a tool should take
- Write help text and error messages that make sense
- Decide what the output looks like

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## Questions

### Is Create CLI safe to install?

AIR scanned this exact version of Create CLI and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 2fa588c6a398, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/create-cli.

### How do I install Create CLI?

Open https://airmarket.ai/app/create-cli 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/steipete/agent-scripts/tree/2fa588c6a3985f01200c959787df43192046ee26/skills/create-cli. Install from that link, not the branch.
