Receiving Code Review
Core Principle
Verify before implementing. Technical correctness matters more than social comfort. A reviewer can be wrong -- blindly implementing bad suggestions creates bugs.
Response Pattern
For each piece of feedback, follow this sequence:
0. Prior feedback check (re-reviews only) -- if this is not the first review round, check whether previously flagged issues were addressed before processing new comments. Compare the current diff against prior review threads (gh api repos/{owner}/{repo}/pulls/{pr}/comments). Surface any that were ignored or only partially fixed -- these take priority over new feedback.
- Read -- Understand what's being suggested and why
- Verify -- Is the suggestion technically correct for THIS codebase?
- Evaluate -- Does it improve the code, or is it preference/style?
- Respond -- Agree with evidence, disagree with evidence, or ask for clarification
- Implement -- Only after verification confirms the suggestion is correct
Triage all feedback first (see Implementation Order below), then implement one item at a time. Don't batch-implement everything at once.
Handling Unclear Feedback
When feedback is ambiguous or incomplete:
- Stop -- do not implement anything unclear
- Clarify ALL unclear items before implementing ANY of them (they may be related)
- Ask specific questions: "Are you suggesting X or Y?" not "Can you elaborate?"
- If the reviewer's intent is clear but the technical approach is wrong, say so
Batched clarification for critical-path ambiguity: When multiple ambiguous findings land on critical-path code (auth, payments, data migrations, permission checks) AND the AskUserQuestion tool is available, batch up to 4 of them into a single call rather than asking one at a time. Each question's header is the truncated filename and line, and the options are Valid / False positive / Defer. Skip the batched ask entirely when ambiguous findings are only on non-critical paths — just auto-triage those and move on. If AskUserQuestion is not available, fall back to a single prose block listing all ambiguous items numbered, asking for Valid/False-positive/Defer decisions. The batching limit is 4 because it caps cleanly at that size; asking more becomes noise rather than judgment.
Source-Specific Handling
From the user (project owner)
- Trusted context -- they know the codebase and business requirements
- Implement after understanding, but still verify technical correctness
- Ask clarifying questions when the intent is clear but the approach seems risky
- No performative agreement -- just acknowledge and implement
From automated review agents
- Skeptical by default -- agents lack full context
- Verify every suggestion against the actual codebase
- Check for YAGNI violations (agents love adding "just in case" code)
- Discard suggestions that contradict project conventions (check CLAUDE.md)
- Agents may flag things that are intentional design decisions -- check before changing
From external reviewers (PR comments, open source)
- Verify technical correctness for THIS stack and codebase
- Check if the suggestion applies to this version of the framework/library
- Push back if the reviewer lacks context about architectural decisions
- Distinguish between "this is wrong" and "I would do it differently"
When to Push Back
Push back (with evidence) when a suggestion:
- Breaks existing functionality -- "This would break X because Y depends on Z"
- Violates project conventions -- "Our CLAUDE.md specifies we do it this way because..."
- Is technically incorrect -- "This API was deprecated in v3. We're on v4 which uses..."
- Adds unnecessary complexity -- "This handles a case that can't occur because..."
- Is unused (YAGNI) -- when a reviewer suggests "implementing properly", grep the codebase for actual usage FIRST. Zero callers? Suggest removal: "This endpoint isn't called. Remove it (YAGNI)?" If used, implement properly.
- Conflicts with architectural decisions -- "We chose X over Y in the brainstorm because..."
Valid evidence: code references (file:line), test output, git blame/log, framework docs, reproduction steps, grep results showing usage patterns. Not evidence: "I think", "it should work", "it's fine", appeals to convention without citing the convention, or restating the original code as justification.
False-Positive Taxonomy (for dismissed suggestions)
When dismissing a suggestion (AUTO-DECLINE, manual push-back), tag the dismissal with one of four categories so the reviewer sees structured reasoning, not a bare "no":
| Category | Reviewer's response cited | Evidence required | Maps to "When to Push Back" |
|---|---|---|---|
| FP-ASSUMPTION | Reviewer assumed behavior that doesn't match the code | Quote the specific line that contradicts the assumption | "Is technically incorrect" |
| FP-CONVENTION | Suggestion conflicts with this project's conventions | Cite the CLAUDE.md rule, ADR, or the established pattern in file:line | "Violates project conventions" |
| FP-ALREADY-HANDLED | The concern is handled elsewhere (parent function, middleware, framework) | Show the existing handler in file:line | "Adds unnecessary complexity" |
| FP-OUT-OF-SCOPE | Valid concern but belongs in a separate change | State where it will be tracked (issue, todo, next PR) | YAGNI / scope creep |
Use the tag in the reply: "FP-ALREADY-HANDLED: null check happens in auth/middleware.ts:42 before this handler runs. Keeping as-is." Structured tags prevent the "you're wrong because reasons" reply pattern and make future triage faster (if the same comment class keeps hitting FP-CONVENTION, the convention needs better documentation).
When NOT to Push Back
Accept feedback when:
- The suggestion is correct and you missed something
- It catches a genuine bug or edge case
- It improves readability without changing behavior
- It aligns with project conventions you overlooked
- The reviewer has domain expertise you lack
Common Mistakes
| Mistake | Fix |
|---|---|
| Agreeing before verifying | Verify first, then state what you found |
| Implementing without understanding impact | Trace the change through callers before editing |
| Apologizing instead of fixing | State the correction factually, then implement |
| Thanking the reviewer instead of responding technically | Delete "Thanks" -- state the fix instead |
| Pushing back without evidence | Include the specific code path or test that proves your point |
| Batch-implementing then testing | Test after each individual fix |
| Can't verify the suggestion | Say so: "Can't verify this without [X]. Should I [investigate/ask/proceed]?" -- don't guess or implement blind |
Approved Response Templates
When feedback IS correct: "Verified -- [specific issue]. Implementing [specific fix]." When feedback is partially correct: "The [X part] is right because [reason]. The [Y part] doesn't apply here because [evidence]." When you need clarification: "Can you clarify [specific ambiguity]? The comment could mean [A] or [B], which changes the fix."
Implementation Order
After triaging all feedback:
- Clarify -- resolve all unclear items first
- Blocking issues -- fix things that break functionality
- Simple fixes -- quick wins that are clearly correct
- Complex fixes -- changes that need careful implementation
Test after each individual fix, not after implementing everything.
When Your Pushback Was Wrong
State the correction factually: "Checked this, you're correct because [reason]. Implementing." No extended apology, no self-deprecation -- just acknowledge and move on.
GitHub PR Reviews
- Reply in the inline comment thread, not as top-level PR comments:
gh api repos/{owner}/{repo}/pulls/{pr}/comments -f body="..." -f in_reply_to={comment_id} - Reference specific lines when explaining why you disagree
- Mark conversations as resolved only after the fix is verified
- If a suggestion spawns a larger discussion, suggest moving it to an issue
Headless Mode
When invoked programmatically (by another skill or command with mode:headless), skip interactive prompts and return structured triage results. See headless-mode.md for the classification table (AUTO-FIX / AUTO-DECLINE / ESCALATE), output format, and constraints.
Scope vs ia-pr-comment-resolver Agent
This skill and the ia-pr-comment-resolver agent handle different situations:
| This skill (interactive) | This skill (headless) | ia-pr-comment-resolver agent | |
|---|---|---|---|
| When | Interactive review requiring judgment | Programmatic triage by another skill/command | Implementing a single pre-triaged comment |
| Approach | Verify, evaluate, potentially push back | Auto-classify and return triage results | Implement a single pre-classified change |
| Skepticism | High -- check correctness first | High -- same rules, automated classification | Low -- comments are pre-triaged |
| Use for | Unclear suggestions, architectural feedback | Batch triage before dispatching resolvers | Clear-cut fixes, style nits, typos |
When the ia-pr-comment-resolver agent encounters feedback that requires judgment (architectural decisions, debatable trade-offs), it should escalate rather than implement.
Examples
Bad -- performative agreement:
Reviewer: "This should use a Map instead of an object for better performance." Response: "Great catch! Switching to Map now."
Good -- verify first:
Reviewer: "This should use a Map instead of an object for better performance." Response: "Checked this -- the object has at most 5 keys (bounded by the enum). Map overhead isn't justified here. Keeping as-is."
Bad -- blind implementation:
Reviewer: "Add null checks for the user parameter." Response: "Done, added null checks."
Good -- verify the premise:
Reviewer: "Add null checks for the user parameter." Response: "Traced the call chain -- user comes from the auth middleware which guarantees non-null (throws 401 otherwise). Adding a null check here would be dead code. Should I add it anyway for defense-in-depth?"Good -- unclear item:
Reviewer: "This logic seems off." Response: "Can you clarify which part? The filter predicate, the sort order, or the pagination logic?"
Verify
- All feedback items triaged (classified as correct, incorrect, or unclear)
- Ambiguous items clarified before any implementation
- Each fix verified individually (test after each, not batch)
- No performative agreement phrases in responses ("Great catch!", "Absolutely right")
Integration
This skill pairs with:
ia-code-review-- the outbound side (requesting reviews). Their action-routing tiers (safe_auto/gated_auto/manual/advisory) roughly map to this skill's AUTO-FIX / ESCALATE-for-approval / ESCALATE / FYI.ia-pr-comment-resolveragent -- for mechanical PR comment resolution (see scope table above)ia-verification-before-completion-- verify each fix before marking resolved
