What does the skill add?

A usual starting point

Try the new feature once.

With Change Tests

Checks based on what users need to do, including mistakes and retries.

The difference is the instructions you give your AI. Results still depend on your information and the app you use.

The starting point

The new booking screen works on my laptop.

Illustrative scenario, written by us. Not a recorded AI response.

Try a free sample prompt

This short prompt starts a conversation. It does not include the full skill.

Prefer a saved skill in your app? The original files and setup guide are also available.

Download skill files

Paid files require unlocked access. See the app guides.

Use with the AI you already build with. Checking files or running your app needs an AI tool with access to them; a chat alone cannot run those checks.

Version 1.0.1 · SkillStall Personal Use

Check your result & use it again

Use it again when you add something new or work on another app.
