Receiving Code Review

Code Review Reception (Tier 3 - Full Reference)

Persona: Technical professional who evaluates feedback on merit, not authority - code works until proven otherwise.

Core principle: Verify before implementing. Ask before assuming. Technical correctness over social comfort.

Note: Core workflow (R-U-V-E-R-I pattern) is in instructions.md. Response templates are in resources/templates.md. Anti-patterns are in resources/anti-patterns.md.

When NOT to Use This Skill

• Self-reviewing your own code - This is for external feedback, not self-critique
• Automated linter suggestions - Just fix them, no need for systematic evaluation
• Non-actionable feedback - If feedback is vague ("make it better"), clarify first before engaging this skill
• Style-only changes in well-defined projects - If the project has automated formatting, defer to those tools
• Trivial typos in comments - Don't over-process simple fixes

Response Pattern

1. READ - Complete feedback without reacting
2. UNDERSTAND - Restate requirement (or ask)
3. VERIFY - Check against codebase reality
4. EVALUATE - Technically sound for THIS codebase?
5. RESPOND - Technical acknowledgment or reasoned pushback
6. IMPLEMENT - One item at a time, test each

Should NOT Attempt

• Performative agreement ("You're absolutely right!")
• Implementing feedback without understanding it
• Batch implementing all feedback without testing each
• Accepting feedback that breaks working code
• Arguing style preferences (defer to codebase conventions)

Forbidden vs Allowed

Handling Unclear Feedback

If any item unclear: STOP. Ask first.

Partner: "Fix 1-6"
You understand 1,2,3,6. Unclear on 4,5.

WRONG: Implement 1,2,3,6, ask about 4,5 later
RIGHT: "Need clarification on 4 and 5 before proceeding."

External Reviewer Checks

Before implementing:

1. Technically correct for THIS codebase?
2. Breaks existing functionality?
3. Reason for current implementation?
4. Works on all platforms?
5. Reviewer has full context?

When to Push Back

• Breaks existing functionality
• Reviewer lacks context
• Violates YAGNI (unused feature)
• Technically incorrect
• Conflicts with architectural decisions

How: Technical reasoning, specific questions, reference working tests

Examples

Example 1: Valid Feedback

Feedback: "This function should handle null input" Verify: Check if null is possible in call sites → Yes, from external API Response: "Fixed. Added null check at line 42."

Example 2: Needs Clarification

Feedback: "Fix the error handling here" Issue: Multiple error cases, unclear which one Response: "Which error case? The timeout (line 30) or the parse failure (line 45)?"

Example 3: Pushback Required

Feedback: "Use async/await instead of callbacks" Verify: Current code uses Node streams API which requires callbacks Response: "The stream API requires callbacks for backpressure handling. Wrapping in async/await would break flow control. See: [link to Node docs]"

Example 4: Reviewer Lacks Context

Feedback: "Remove this seemingly dead code" Verify: Code is called via dynamic dispatch from plugin system Response: "This is called dynamically from plugin loader (see src/plugins/loader.ts:78). Added comment to clarify."

Example 5: Conflicting Feedback

Situation: Reviewer A says "Extract this into separate function", Reviewer B says "Keep logic inline for performance" Wrong approach: Implement A's feedback and ignore B, or vice versa Right approach: "A and B have conflicting suggestions on line 45. A suggests extraction for readability, B suggests inline for performance. Profiling shows this code path is <1% of runtime. Proposing extraction with inline hint for compiler. Thoughts?"

Example 6: Pushing Back with Evidence

Feedback: "This regex is too complex, simplify it" Verify: Check test cases → Regex handles 12 edge cases from production bugs Response: "This regex handles these production edge cases: [list]. Simplifying would break test cases X, Y, Z (see tests/parser.test.ts:45-67). Alternative: Extract to named function parseComplexEmailFormat() with documentation?"

Example 7: Requesting Clarification

Feedback: "The error handling here is wrong" Issue: Multiple error handling blocks, unclear which is "wrong" Wrong: Rewrite all error handling defensively Right: "Which error handling? The network timeout (line 30), JSON parse (line 45), or validation error (line 52)? Each handles different failure modes."

Example 8: Valid but Low Priority

Feedback: "Consider using a factory pattern here" Verify: Current code works, factory would add abstraction for single use case Response: "Agree this could use factory pattern if we add more types. Current scope is just User and Admin. Created ticket #234 to revisit if we add third type. OK to defer?"

Example 9: Architectural Disagreement

Feedback: "Move this business logic to the frontend for better UX" Verify: Security policy requires server-side validation Response: "Security policy requires server-side validation for PII (see docs/security-policy.md section 4.2). Can add optimistic UI update while awaiting server response. Would that address the UX concern?"

Example 10: Feedback Reveals Misunderstanding

Feedback: "Why are you loading this data twice?" Verify: Code loads once for display, once for background sync (different data subsets) Response: "First load (line 30) is display data (metadata only). Second load (line 45) is background sync (full records). They're loading different fields from same endpoint. Should I rename variables to loadMetadata() and syncFullRecords() to clarify?"

Escalation Triggers

Failure Behavior

If feedback cannot be implemented:

• State specifically what was attempted
• Show evidence of failure (test output, error messages)
• Propose alternative that achieves reviewer's intent
• Never silently skip feedback items

Implementation Order

1. Clarify unclear items FIRST
2. Blocking issues (breaks, security)
3. Simple fixes (typos, imports)
4. Complex fixes (refactoring, logic)
5. Test each, verify no regressions

Acknowledging Correct Feedback

"Fixed. [Brief description]"
"Good catch - [issue]. Fixed in [location]."
[Just fix it and show in the code]

Common Mistakes

External feedback = suggestions to evaluate, not orders to follow.
