How to Request a Second Opinion on a Bug in English
Learn the English phrases for asking a teammate to look at a confusing bug: framing what you've tried, what you suspect, and what kind of help you need.
“Can someone look at this?” with no other context makes it hard for a teammate to help efficiently — they don’t know what you’ve already ruled out, what you suspect, or how urgent it is. This guide covers how to ask for debugging help in a way that gets you useful input fast.
Key Vocabulary
Ruled out — something you’ve already checked and confirmed isn’t the cause, worth stating explicitly so a second pair of eyes doesn’t waste time re-investigating it. “I’ve ruled out the network layer — the request is definitely reaching the server, since it shows up in the access logs with a 200 status.”
Working theory — your current best guess at the cause, stated as a hypothesis rather than a conclusion, giving the other person something concrete to confirm or challenge. “My working theory is that the cache is serving a stale value after the invalidation event fires, but I haven’t confirmed that’s actually what’s happening yet.”
Sanity check — a quick, low-effort ask for someone to verify your reasoning or a specific assumption, distinct from asking them to do a full independent investigation. “Quick sanity check before I dig further: does it seem right to you that this endpoint should be idempotent, or am I wrong about that assumption?”
Fresh eyes — an explicit acknowledgment that you might be missing something obvious because you’ve been staring at the problem too long, inviting the other person to question your assumptions rather than just build on them. “I’ve been staring at this for two hours and might be anchored on the wrong assumption — could use some fresh eyes on whether I’m even looking in the right place.”
Common Phrases
- “Here’s what I’ve ruled out so far: …”
- “My working theory right now is X, but I haven’t confirmed it.”
- “Quick sanity check before I go further down this path: …”
- “I could use some fresh eyes — I might be anchored on the wrong assumption.”
- “Do you have ten minutes to look at this with me, or should I write it up for async review?”
Example Sentences
Asking for help with full context: “Stuck on a bug where orders occasionally get double-charged. I’ve ruled out the idempotency key logic — that’s confirmed working in the logs. My working theory is a race between the webhook handler and the manual retry path, but I haven’t proven it yet. Could someone sanity-check that theory before I go further?”
Requesting synchronous help for something urgent: “This is affecting production right now, so I’d rather not go fully async — do you have fifteen minutes to pair on this? I’ll share my screen and walk through what I’ve found so far.”
Asking for fresh eyes after being stuck: “I’ve been on this for a few hours and keep coming back to the same dead end, which makes me think I’m anchored on a wrong assumption somewhere. Could you look at this without reading my notes first, just to see if you land somewhere different?”
Professional Tips
- Always list what you’ve ruled out before asking for help — it’s the single biggest time-saver for whoever’s helping, since it stops them from re-treading ground you’ve already covered.
- State your working theory explicitly, even a tentative one — it gives the helper something to react to, which is much faster than starting a debugging session from a blank slate.
- Use sanity check for a narrow, quick ask and be explicit that it’s not a request for a full investigation — this sets the right time expectation for both people.
- Say fresh eyes explicitly when you suspect you’re anchored on a wrong assumption — it invites someone to actively question your framing rather than just build on top of it.
Practice Exercise
- Write a debugging help request that states what’s been ruled out and your working theory.
- Write a sanity-check question that’s clearly scoped to a quick, low-effort ask.
- Write a message asking for fresh eyes after being stuck on a problem for a while.
