Reviewer: "This will cause a race condition in production."
 
❌ Bad response: "Works on my machine"
✅ Good response: "You're right! Fixed in abc123. Added test to prevent this."

Reviewer: "Consider extracting this into a helper function"
 
❌ Bad: "Not necessary"
✅ Good: "Great idea! Done in xyz789"
✅ Also good: "I kept it inline because this logic is used only once here,
             but happy to extract if you feel strongly"

Reviewer: "Why did you choose approach A over B?"
 
❌ Bad: "Because it's better"
✅ Good: "I chose A because of X constraint. B would require Y which adds 
         complexity. Happy to reconsider if you see an issue with A"

Reviewer: "nit: missing comma here"
 
❌ Bad: "It's optional in JS"
✅ Good: "Fixed! Thanks for catching that"

✅ Good openings:
- "Thanks for the detailed review!"
- "Great catches, appreciate your time"
- "Thanks for the feedback—addressing these now"
 
❌ Avoid:
- Starting with defensive explanations
- No acknowledgment

Reviewer: "This function is doing too much"
 
Your response:
"You're absolutely right. I've split it into three functions:
- validateInput() for validation
- processData() for business logic  
- formatOutput() for formatting
 
Changes in commit abc1234. Does this look better?"

Reviewer: "The naming here is confusing"
 
Your response:
"Thanks for pointing this out. Which variable names specifically? 
I'm thinking:
- `userData` → `authenticatedUser`
- `data` → `requestPayload`
 
Would that address your concern?"

After addressing feedback:
 
"All feedback addressed:
✅ Fixed race condition (commit abc1234)
✅ Extracted helper function (commit def5678)
✅ Added error handling (commit ghi9012)
✅ Updated tests accordingly
 
Please take another look when you have time. Thanks!"

Reviewer: "This is completely wrong. You clearly didn't read the docs."
 
❌ Bad: "That's rude"
✅ Good: "You're right, I missed that in the docs. Fixed now. 
         Which section should I review more carefully?"

Reviewer: "This doesn't feel right"
 
❌ Bad: "Can you be more specific?"
✅ Good: "I want to make sure I address your concern. Is it:
         - The approach itself?
         - The implementation details?
         - Performance implications?
         - Something else?
         
         Happy to explain my reasoning or change direction."

Reviewer A: "Extract this into a separate file"
Reviewer B: "Keep this in the same file for cohesion"
 
Your response:
"@reviewerA and @reviewerB have different preferences here. 
I'm inclined toward [choice] because [reason]. 
Can you two align on the preferred approach? Happy to go either way."

Example:
 
"Thanks for suggesting we use Library X instead of Y.
 
I chose Y because:
1. It's 10x smaller (5KB vs 50KB)
2. Active maintenance (updated last week vs 2 years)
3. Better TypeScript support
 
That said, I might be missing context about X's benefits for this project. 
Is there a specific advantage you see that outweighs these factors?
 
Of course, if you prefer X for project consistency, I'm happy to switch."

Reviewer: "Missing semicolon on line 45"
 
Response: "Fixed in abc1234. Thanks!"

Reviewer: "Why not use approach B?"
 
Response: "I considered B but went with A because [reasons].
 
Trade-offs:
- A: Pros X, Cons Y
- B: Pros Z, Cons W
 
Given [project constraints], A seemed better fit. But if you see 
issues with this reasoning, I can switch to B."

Reviewer: "We should also refactor module X while we're here"
 
Response: "Great point! That's a bigger change though. Would you prefer:
1. I do it in this PR (delays merge by ~3 days)
2. I create a follow-up issue and tackle separately
 
I'm leaning toward option 2 to keep this PR focused, but happy to do 1 
if you think it's important to couple these changes."

Reviewer: "This needs error handling"
 
Response: "Good catch! I actually added that in commit def5678 
(lines 45-52). Does that address your concern?"

Reviewer: "This entire approach should be redesigned"
 
Response: "I think you're right that the overall architecture could be improved. 
 
This PR specifically addresses issue #123 within the current architecture. 
 
Would you prefer:
1. I open a separate issue for the architecture discussion
2. I pause this PR and tackle the redesign first
3. We merge this as-is and refactor in a follow-up
 
What do you think?"

# Option 1: Separate commits per concern
git commit -m "fix: address race condition from review"
git commit -m "refactor: extract helper as suggested"
git commit -m "test: add edge cases requested"
 
# Option 2: Single commit (for very small changes)
git commit -m "fix: address review feedback
 
- Fix race condition in auth flow
- Extract validateUser helper
- Add edge case tests"

Reviewer: "Can you add tests for the error case?"
 
Response: "Added three test cases in test/auth.test.js:
- Invalid token → 401
- Expired token → 403  
- Missing token → 400
 
All passing. Commit: abc1234"

Reviewer: "This might be slow with large datasets"
 
Response: "Good point. I ran benchmarks:
- 100 items: 5ms
- 1,000 items: 48ms
- 10,000 items: 450ms
 
For our use case (max 1000 items), this should be fine. 
But if you expect larger datasets, I can optimize with [approach]."

Reviewer: "Is this input sanitized?"
 
Response: "Yes, sanitized on line 67 using escapeHtml().
Also added a test to verify XSS prevention (line 120).
 
Let me know if you'd like additional sanitization."

Maintainer A: "LGTM! ✅"
 
[But there are 2 other reviewers]
 
Your response: "Thanks @maintainerA! 
Waiting for @maintainerB and @maintainerC to review as well."

All reviewers approved
 
Your response (optional): "Thank you all for the thorough review! 
Learned a lot from your feedback."
 
[Wait for maintainer to merge—don't merge your own PR unless told to]

Bad:
"No, you're wrong. My way is better because [5 paragraphs]"
 
Good:
"I understand your concern. I chose this approach because [brief reason]. 
What issues do you see with it?"

Bad:
"I disagree but I'll change it"
 
Good:
"I see your point. Changed to your suggestion in commit abc1234"

Bad:
[10 paragraphs explaining every decision]
 
Good:
"Changed as suggested. Happy to explain the reasoning if helpful."

Bad:
"You always criticize my PRs"
 
Good:
"Thanks for the feedback. I'll address these points."

Polite ping:
 
"Hi @reviewer, just checking if you had a chance to look at the updates. 
No rush—just want to make sure this is on your radar. Thanks!"

Tag project lead:
 
"Hi @maintainer, this PR has been waiting for review for 2 weeks. 
Could someone take a look, or should I close and revisit later?"

"Closing this PR due to inactivity. Happy to reopen if there's renewed 
interest. Thanks for the initial feedback!"
