Section 1
The big idea
Beginners paste 'TypeError: undefined is not a function' and ask 'why?'. Pros paste the whole stack trace, the function that called it, and the input that caused it. Claude or ChatGPT doesn't have a crystal ball — it has whatever context you give it. More context, better answer. Period.
Some examples
- You paste a Python traceback with all 12 lines — Claude pinpoints line 7 in your file, not the library's.
- You include the JSON that triggered the bug — ChatGPT sees a missing field instantly.
- You add the failing test name and assertion — Cursor proposes a one-line fix.
- You include `console.log` output of the variable values — the AI catches a string-vs-number mixup.
Try it!
Next bug you hit: paste the FULL stack trace, the calling function, AND the input that broke it. Watch the answer quality jump.
