What it does
Code written quickly can work on your laptop and still fail in front of a customer. The problems are often hidden: a key in the file, an error that is swallowed, a call that waits forever. This prompt looks for those problems and nothing else. It points to the place in your code, says what happens if it fails, and suggests the smallest change. It leaves style opinions alone.
You give it
- The code, in full
- What it is for and who uses it
- Where it will run (optional)
You get
- A two-line summary of what the code does
- Ranked findings, each with its place and smallest fix
- What is fine and worth keeping
- What it could not tell from the code alone
Use it when
- An AI built something for you and it seems to work.
- You are about to show a prototype to real users.
- You are handing a quick project to someone else.
How to use it
- Copy the prompt, then paste it into your AI chat (Claude, ChatGPT or Gemini).
- Under it, paste your details, one item for each line in What you need.
- Send it and read the reply against the checks at the end of the prompt.
- Answer anything marked MISSING and send it again, or ask for one part to be redone.
