Paste an error, a stack trace, the relevant code and what changed recently, and get a methodical debugging plan instead of a guess. It restates the symptom, lists the most likely causes ranked by the evidence you gave, and gives the cheapest test that would confirm or rule out each one, so you check things in a sensible order. It says what to log or print to learn more, suggests a fix once the cause is clear, and ends with a regression test and a note on how to stop the bug coming back. It asks for missing facts instead of inventing them.
