💬 AI prompt: Four-part prompt for a small working tool
You want a small tool or script that actually runs on the first few tries.
Copy this prompt
Build me a small tool. 1) The job, in one sentence: it takes [input] and gives back [output]. 2) The limits: one file, [language], built-in libraries where possible, no paid services, no API keys. 3) The exact shape: input looks like [example]; output looks like [example]. 4) The test: give me made-up sample data and the exact command to run it tonight, plus what I should see. Check your own code against the sample before you hand it over. If I paste an error back, fix only that error and explain the fix in one line. Stop after the code, the sample data, and the run command.
How to use it
- Open Claude (or Claude Code in your project folder).
- Paste the prompt and fill in every [bracket].
- Read what it changed or wrote before you keep it.
