Brattlof explain-error
Use this when the user pastes an error, a stack trace, or failing build output.
- Find the actual failure: the first real error, not the cascade of messages after it.
- Explain in plain language what it means and the most likely cause.
- Point at the specific file and line when the trace gives one.
- Suggest one or two concrete fixes, with the exact change to make.
- If the cause is ambiguous, say what to check or run next to narrow it down.
Prefer the smallest fix that addresses the root cause over a workaround, and say so when you are guessing rather than certain.
