Debug properly: root-cause analysis, a minimal fix, and regression tests that provably fail on the original code before they pass on the fix.

The worked examples were verified by actually running the code. Full prompt plus 4 fully worked examples. Works with Claude, ChatGPT, and Gemini.

Delivered as 1 ZIP file of about 16 KB containing the full copy-paste prompt as a plain-text file with fill-in variables and 4 worked example files with real inputs and real outputs, ready to paste into Claude, ChatGPT, or Gemini whenever you need to debug properly with root-cause analysis, a minimal fix, and regression tests that provably fail on the original code before they pass on the fix, and licensed for personal and internal business use, so the same prompt and examples that were verified by actually running the code can be reused for your next bug in any of the three supported chatbots, with the same fill-in variables and the same 4 worked examples to follow every time.
