# Skill Creator

Write, test, and tune your own skills until they behave

## What this does

You want your assistant to handle a job the same way every time, so you save the instructions as a skill. This helps you write one from scratch, fix up one you already have, and check with practice runs whether it really does what you meant. Reach for it before your first skill, or any time a skill keeps switching on when it should not.

### Top 3 things it does for you

- Draft a brand new skill from scratch
- Improve an existing skill that needs work
- Put a skill through test runs before trusting it

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.

## About Skill Creator

This covers the whole life of a skill: creating one when you have nothing yet, editing one that already exists, and improving it.

To find out whether a change actually helped, you can put a skill through evals and compare how versions perform. That comparison pays attention to how much results vary between runs, so one lucky attempt does not get mistaken for real improvement.

There is also the quieter failure where a skill works fine but rarely gets used because its description does not match what people ask for. Rewriting that description makes the skill trigger more accurately, so it steps in at the right moments.

## Questions

### Is Skill Creator safe to install?

AIR scanned this exact version of Skill Creator and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 690f15cac7f7, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/skill-creator.

### How do I install Skill Creator?

Open https://airmarket.ai/app/skill-creator 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/skills/tree/690f15cac7f7b4c055c5ab109c79ed9259934081/skills/skill-creator. Install from that link, not the branch.
