What it does for you

Is your new prompt really better? Check it

Tweaking a prompt by gut feeling fixes one case and quietly breaks another. This method compares old and new versions blind on 6 to 15 fixed cases, and a clear rule makes the call while protecting your critical cases.

  • Compare two versions side by side, without knowing which
  • Avoid any regression on the cases that matter
  • Get a reasoned decision, case by case
