When you hit a cryptic error message, don’t Google it. Paste it into your Copilot chat.

But here’s the key: ask for the explanation first, not the fix.

“Here’s the error I’m getting: [paste]. Explain what’s causing this before suggesting a fix.”

The explanation often reveals the real issue — not the symptom the error message describes. Once you understand the root cause, the fix usually becomes obvious. And when it doesn’t, you can follow up with /fix on the problematic code.

Two shortcuts that save time:

  • /explain — select the code, type /explain, get a plain-language breakdown
  • @terminal (VS Code only) — reference your terminal output directly in Chat. Copilot sees the error in context

GitHub proposes: “Instead of asking ‘What’s wrong with this function?’ try ‘Why is this function returning undefined when the input is valid?’” Specificity gets you better answers.

💡 Try this: Next time you hit a stack trace, paste it into Copilot chat and ask “explain this error” before you ask for a fix.
