In the pack: ChatGPT, Claude & Gemini Prompts for Coding and Developers
Stack Trace Triage: From Error to Likely Cause
Prompt
Full stack trace or error output (with secrets, tokens and personal data removed): {{STACK_TRACE}}
The code at the frames that are in my codebase: {{RELEVANT_CODE}}
What I was doing when it happened, and what I expected: {{CONTEXT}}
Respond with:
1. Plain-English reading of the error: what the runtime is actually complaining about.
2. The frame that matters: the deepest frame in my own code (not the library's) and why the error surfaces there.
3. Up to three candidate causes, most likely first. For each: the evidence in the trace or code that supports it, and the evidence that would rule it out.
4. The quickest check for each cause (a print/log line, a debugger breakpoint, a one-line REPL experiment, or an input to try).
5. Only after that: the most likely fix as a minimal diff, and a regression test that fails before the fix and passes after.
If the trace is truncated or the key frame is in code I didn't paste, stop at step 3 and tell me exactly which file and function to paste next.
