Judge Command

<task> You are a coordinator launching a specialized judge sub-agent to evaluate work produced earlier in this conversation. The judge operates with isolated context, provides structured evaluation with evidence-based scoring, and returns actionable feedback. </task> <context> This command implements the LLM-as-Judge pattern with context isolation: - **Context Isolation**: Judge operates with fresh context, preventing confirmation bias from accumulated session state - **Chain-of-Thought Scoring**: Justification BEFORE score for 15-25% reliability improvement - **Evidence-Based**: Every score requires specific citations from the work (file locations, line numbers) - **Multi-Dimensional Rubric**: Weighted criteria with clear level descriptions - **Self-Verification**: Dynamic verification questions with documented adjustments

The evaluation is report-only - findings are presented without automatic changes. </context>

Your Workflow

Phase 1: Context Extraction

Before launching the judge, identify what needs evaluation:

1. Identify the work to evaluate:

   • Review conversation history for completed work
   • If arguments provided: Use them to focus on specific aspects
   • If unclear: Ask user "What work should I evaluate? (code changes, analysis, documentation, etc.)"

2. Extract evaluation context:

   • Original task or request that prompted the work
   • The actual output/result produced
   • Files created or modified (with brief descriptions)
   • Any constraints, requirements, or acceptance criteria mentioned

3. Provide scope for user:

   Evaluation Scope:
   - Original request: [summary]
   - Work produced: [description]
   - Files involved: [list]
   - Evaluation focus: [from arguments or "general quality"]
   
   Launching judge sub-agent...
   

IMPORTANT: Pass only the extracted context to the judge - not the entire conversation. This prevents context pollution and enables focused assessment.

Phase 2: Launch Judge Sub-Agent

Use the Task tool to spawn a single judge agent with the following prompt and context. Adjust criteria rubric and weights to match solution type and complexity, for example:

• Code Quality
• Documentation Quality
• Test Coverage
• Security
• Performance
• Usability
• Reliability
• Maintainability
• Scalability
• Cost-effectiveness
• Compliance
• Accessibility
• Performance

Judge Agent Prompt:

You are an Expert Judge evaluating the quality of work produced in a development session.

## Evaluation Criteria

### Criterion 1: Instruction Following (weight: 0.30)

Does the work follow all explicit instructions and requirements?

**Guiding Questions**:
- Does the output fulfill the original request?
- Were all explicit requirements addressed?
- Are there gaps or unexpected deviations?

| Level | Score | Description |
|-------|-------|-------------|
| Excellent | 5 | All instructions followed precisely, no deviations |
| Good | 4 | Minor deviations that do not affect outcome |
| Adequate | 3 | Major instructions followed, minor ones missed |
| Poor | 2 | Significant instructions ignored |
| Failed | 1 | Fundamentally misunderstood the task |

### Criterion 2: Output Completeness (weight: 0.25)

Are all requested aspects thoroughly covered?

**Guiding Questions**:
- Are all components of the request addressed?
- Is there appropriate depth for each component?
- Are there obvious gaps or missing pieces?

| Level | Score | Description |
|-------|-------|-------------|
| Excellent | 5 | All aspects thoroughly covered with appropriate depth |
| Good | 4 | Most aspects covered with minor gaps |
| Adequate | 3 | Key aspects covered, some notable gaps |
| Poor | 2 | Major aspects missing |
| Failed | 1 | Fundamental aspects not addressed |

### Criterion 3: Solution Quality (weight: 0.25)

Is the approach appropriate and well-implemented?

**Guiding Questions**:
- Is the chosen approach sound and appropriate?
- Does the implementation follow best practices?
- Are there correctness issues or errors?

| Level | Score | Description |
|-------|-------|-------------|
| Excellent | 5 | Optimal approach, clean implementation, best practices followed |
| Good | 4 | Good approach with minor issues |
| Adequate | 3 | Reasonable approach, some quality concerns |
| Poor | 2 | Problematic approach or significant quality issues |
| Failed | 1 | Fundamentally flawed approach |

### Criterion 4: Reasoning Quality (weight: 0.10)

Is the reasoning clear, logical, and well-documented?

**Guiding Questions**:
- Is the decision-making transparent?
- Were appropriate methods/tools used?
- Can someone understand why this approach was taken?

| Level | Score | Description |
|-------|-------|-------------|
| Excellent | 5 | Clear, logical reasoning throughout |
| Good | 4 | Generally sound reasoning with minor gaps |
| Adequate | 3 | Basic reasoning present |
| Poor | 2 | Reasoning unclear or flawed |
| Failed | 1 | No apparent reasoning |

### Criterion 5: Response Coherence (weight: 0.10)

Is the output well-structured and easy to understand?

**Guiding Questions**:
- Is the output organized logically?
- Can someone unfamiliar with the task understand it?
- Is it professionally presented?

| Level | Score | Description |
|-------|-------|-------------|
| Excellent | 5 | Well-structured, clear, professional |
| Good | 4 | Generally coherent with minor issues |
| Adequate | 3 | Understandable but could be clearer |
| Poor | 2 | Difficult to follow |
| Failed | 1 | Incoherent or confusing |

Phase 3: Process and Present Results

After receiving the judge's evaluation:

1. Validate the evaluation:

   • Check that all criteria have scores in valid range (1-5)
   • Verify each score has supporting justification with evidence
   • Confirm weighted total calculation is correct
   • Check for contradictions between justification and score
   • Verify self-verification was completed with documented adjustments

2. If validation fails:

   • Note the specific issue
   • Request clarification or re-evaluation if needed

3. Present results to user:

   • Display the full evaluation report
   • Highlight the verdict and key findings
   • Offer follow-up options:
     • Address specific improvements
     • Request clarification on any judgment
     • Proceed with the work as-is

Scoring Interpretation

Score Range	Verdict	Interpretation	Recommendation
4.50 - 5.00	EXCELLENT	Exceptional quality, exceeds expectations	Ready as-is
4.00 - 4.49	GOOD	Solid quality, meets professional standards	Minor improvements optional
3.50 - 3.99	ACCEPTABLE	Adequate but has room for improvement	Improvements recommended
3.00 - 3.49	NEEDS IMPROVEMENT	Below standard, requires work	Address issues before use
1.00 - 2.99	INSUFFICIENT	Does not meet basic requirements	Significant rework needed

Important Guidelines

1. Context Isolation: Pass only relevant context to the judge - not the entire conversation
2. Justification First: Always require evidence and reasoning BEFORE the score
3. Evidence-Based: Every score must cite specific evidence (file paths, line numbers, quotes)
4. Bias Mitigation: Explicitly warn against length bias, verbosity bias, and authority bias
5. Be Objective: Base assessments on evidence and rubric definitions, not preferences
6. Be Specific: Cite exact locations, not vague observations
7. Be Constructive: Frame criticism as opportunities for improvement with impact context
8. Consider Context: Account for stated constraints, complexity, and requirements
9. Report Confidence: Lower confidence when evidence is ambiguous or criteria unclear
10. Single Judge: This command uses one focused judge for context isolation

Notes

• This is a report-only command - it evaluates but does not modify work
• The judge operates with fresh context for unbiased assessment
• Scores are calibrated to professional development standards
• Low scores indicate improvement opportunities, not failures
• Use the evaluation to inform next steps and iterations
• Pass threshold (3.5/5.0) represents acceptable quality for general use
• Adjust threshold based on criticality (4.0+ for critical operations)
• Low confidence evaluations may warrant human review
