Prompt

I have a bug: ${bug}. Take a test-first approach: 1) Read the relevant source files and existing tests. 2) Write a failing test that reproduces the exact bug. 3) Run the test suite to confirm it fails. 4) Implement the minimal fix. 5) Re-run the full test suite. 6) If any test fails, analyze the failure, adjust the code, and re-run—repeat until ALL tests pass. 7) Then grep the codebase for related code paths that might have the same issue and add tests for those too. 8) Summarize every change made and why. Do not ask me questions—make reasonable assumptions and document them.

How to use this prompt

    Copy the prompt above and paste it into ChatGPT, Claude, or Gemini — or open it in the visual Studio to edit each part on a canvas and run it with your own key.

  2. 2

    Replace any bracketed placeholders with your specifics. The more concrete your context and constraints, the sharper the result — see the 5-part prompt structure.
