For each claim/requirement/decision, verify:

□ Is this explicitly stated in the PRD?
  - YES: ✓ Traceable
  - NO: Check if reasonable inference

□ If inferred, is the inference justified?
  - Is it based on project patterns?
  - Is it based on technical necessity?
  - Is it marked as an assumption?

□ Are all quotes accurate?
  - Compare against original PRD
  - No paraphrasing without marking

□ Are technical claims verifiable?
  - Can be confirmed from codebase?
  - Based on documentation?
  - Standard practice?

□ For custom configurations:
  - Is implementation using its OWN defined constants?
  - Or accidentally using defaults from research?

Hallucination Score = (Phantom Items / Total Items) × 100

Thresholds:
- 0-10%: Excellent - Minimal hallucination
- 11-20%: Acceptable - Minor assumptions
- 21-40%: Warning - Needs clarification
- 41%+: Fail - Too much invention

AskUserQuestion(
  questions: [
    {
      question: "The plan assumes [X behavior]. Is this correct?",
      header: "Confirm assumption",
      options: [
        { label: "Yes, correct", description: "Proceed with this behavior" },
        { label: "No, should be Y", description: "Change to different behavior" },
        { label: "Need to discuss", description: "Requires more context" }
      ],

  ]
)

For each proposed element, verify:

□ Is this required by PRD?
  - YES: ✓ Required
  - NO: Is it technically necessary?

□ If not in PRD, is it technically necessary?
  - Error handling for the feature? ✓
  - Generic utility for future? ✗
  - Abstraction for single use? ✗

□ Complexity check:
  - Could this be simpler?
  - Is abstraction premature?
  - Are we building for hypotheticals?

□ Pattern check:
  - Does this follow existing patterns?
  - Are we inventing new patterns?
  - Is deviation justified?

// OVERENGINEERED - Generic for single use
abstract class BaseFeatureController<T extends BaseState> {
  // Only one implementation exists
}

// CORRECT - Simple and direct
class FeatureController extends StateNotifier<FeatureState> {
  // Specific implementation
}

// OVERENGINEERED - Configuration not requested
class Feature {
  final bool enableAdvancedMode;
  final int maxRetries;
  final Duration timeout;
  final String customEndpoint;
  // None of these in requirements
}

// CORRECT - Only what's needed
class Feature {
  final String name;
  final bool isActive;
  // Matches requirements
}

Overengineering Score = (Unnecessary Items / Total Items) × 100

Thresholds:
- 0-10%: Excellent - Minimal extras
- 11-25%: Acceptable - Some reasonable additions
- 26-40%: Warning - Scope creep detected
- 41%+: Fail - Significant overengineering

For each requirement, verify:

□ Is this requirement fully addressed?
  - All acceptance criteria covered?
  - Edge cases handled?
  - Error states defined?

□ Error handling:
  - Network failures?
  - Invalid data?
  - Empty states?
  - Timeout handling?

□ Validation:
  - User input validated?
  - Data type validation?
  - Business rule validation?

□ UI completeness:
  - Loading states?
  - Error states?
  - Empty states?
  - Success feedback?

□ Security considerations:
  - Authentication checked?
  - Authorization handled?
  - Data sanitization?

Underengineering Score = (Missing Items / Required Items) × 100

Thresholds:
- 0-10%: Excellent - Comprehensive
- 11-20%: Acceptable - Minor gaps
- 21-35%: Warning - Needs additions
- 36%+: Fail - Too incomplete

Balance Score = 100 - |Overengineering - Underengineering|/2 - max(Over, Under)/2

Interpretation:
- High Balance (70+): Good equilibrium
- Medium Balance (50-69): Leaning one direction
- Low Balance (<50): Significantly imbalanced

Ideal State:
- Low overengineering (≤15%)
- Low underengineering (≤15%)
- High balance (≥70%)

1. Load artifact to audit (research.md, plan.md, or code diff)
2. Load original PRD/requirements
3. Load project context (AGENTS.md, patterns)

For each item in artifact:
  1. Trace to PRD → Hallucination Check
  2. Assess necessity → Overengineering Check
  3. Check completeness → Underengineering Check
  4. Score and categorize

Findings:
├── CRITICAL: Must fix before proceeding
├── HIGH: Should fix, significant impact
├── MEDIUM: Recommended fix
├── LOW: Nice to fix
└── INFO: Observation only
