Critical: Complete Stage 1 (spec compliance) BEFORE Stage 2 (code quality). Never review code quality for functionality that doesn't meet the specification.

Stage 1: Spec Compliance Review

Core Directive

"The implementer finished suspiciously quickly. Their report may be incomplete, inaccurate, or optimistic."

Approach every review with professional skepticism. Verify claims independently.

The Three Verification Categories

Category 1: Missing Requirements

Check for features that were requested but not implemented.

Question	How to Verify
Did they skip requested features?	Compare PR to original requirements line by line
Are edge cases handled?	Check error paths, empty states, boundaries
Were error scenarios addressed?	Look for try/catch, error boundaries, validation
Is the happy path complete?	Trace through primary use case manually

## Example Review Finding

**Missing Requirement:** Issue #42 requested "password must be at least 8 characters"

**Found in code:**
```typescript
// No length validation present
function validatePassword(password: string) {
  return password.length > 0;  // Only checks non-empty
}

Status: ❌ Incomplete - minimum length validation missing


#### Category 2: Unnecessary Additions

**Check for scope creep and over-engineering.**

| Question | How to Verify |
|----------|---------------|
| Features beyond specification? | Compare to original requirements |
| Over-engineering? | Is complexity justified by requirements? |
| Premature optimization? | Is performance cited without measurements? |
| Unrequested abstractions? | Are there helpers/utils for one-time use? |

```markdown
## Example Review Finding

**Unnecessary Addition:** Added caching layer not in requirements

**Found in code:**
```typescript
// Original requirement: "Fetch user by ID"
// Actual implementation:
class CachedUserRepository {  // Not requested
  private cache = new Map();
  private ttl = 60000;

  async getUser(id: string) {
    if (this.cache.has(id)) { ... }
    // 50 lines of cache logic
  }
}

Status: ⚠️ Scope creep - discuss before merging


#### Category 3: Interpretation Gaps

**Check for misunderstandings of requirements.**

| Question | How to Verify |
|----------|---------------|
| Different understanding of requirements? | Ask author to explain their interpretation |
| Unclarified assumptions? | Look for comments like "assuming..." |
| Ambiguous specs resolved incorrectly? | Compare to similar existing features |

```markdown
## Example Review Finding

**Interpretation Gap:** "Sort by date" implemented as ascending

**Requirement stated:** "Sort by date" (ambiguous)

**Author implemented:** Oldest first (ascending)

**Expected:** Most recent first is typical UX pattern

**Status:** ❓ Clarify - which sort order was intended?

Why Order Matters

Stage 1 Must Come First

Scenario	Waste from Wrong Order
Skip Stage 1	Review 500 lines of code quality, then discover wrong feature was built
Stage 2 First	Suggest refactoring, then realize the code shouldn't exist
Combined	Mix concerns, miss systematic issues

Separation of Concerns

Stage 1 (Spec): Does it do the right thing?
Stage 2 (Quality): Does it do the thing right?

Code quality review is meaningless if the code doesn't implement the correct functionality.

Spec Compliance Checklist

Before You Start

Read the original issue/ticket completely
Identify all explicit requirements
Identify implicit requirements from context
Note any acceptance criteria listed

During Review

Missing Requirements:

All required features present
Edge cases covered (empty, null, max values)
Error handling as specified
Happy path fully functional
UI matches mockups/specs if provided

Unnecessary Additions:

No unrequested features
No speculative abstractions
No premature optimizations
Scope matches requirements exactly

Interpretation Gaps:

Author's understanding matches spec
Ambiguities resolved correctly
Assumptions are documented and valid
Behavior matches similar existing features

After Review

Document all findings with file:line references
Categorize as missing/unnecessary/interpretation
Prioritize: blocking vs. non-blocking issues

Output Format

Compliant Result

## Spec Compliance Review: ✅ PASS

All requirements verified:
- ✅ User can upload profile image (req #1)
- ✅ Image resized to 200x200 (req #2)
- ✅ Invalid formats rejected with error message (req #3)
- ✅ Progress indicator during upload (req #4)

**Proceed to:** Code Quality Review

Issues Found

## Spec Compliance Review: ❌ ISSUES FOUND

### Missing Requirements

1. **Progress indicator not implemented** (req #4)
   - File: `ProfileUpload.tsx`
   - Expected: Progress bar during upload
   - Found: No progress indication

2. **Error messages not user-friendly** (req #3)
   - File: `ProfileUpload.tsx:45`
   - Expected: "Please upload a JPG or PNG file"
   - Found: "Error: INVALID_FORMAT"

### Unnecessary Additions

1. **Image cropping feature not requested**
   - File: `ImageCropper.tsx` (new file, 150 lines)
   - Impact: Adds complexity, delays delivery
   - Recommendation: Remove or create separate PR

**Action Required:** Address missing requirements before code quality review

Common Mistakes to Avoid

Mistake	Why It's Wrong
Reviewing code style before spec compliance	Wasted effort if wrong thing was built
Assuming spec was followed	Verify independently
Skipping edge cases	Bugs hide in boundaries
Accepting "we can add it later"	Technical debt accumulates
Missing scope creep	Unreviewed code enters codebase
