Evaluation Framework Alignment Analysis

Date: November 22, 2025
Reference: Building Best-in-Class AI Evals for Deterministic Multi-Agent Workflows (November 2025)

Executive Summary

Our SDK-based evaluation framework aligns well with Tier 2 (Integration Tests) best practices but has gaps in Tier 1 (Unit Tests) and Tier 3 (Multi-Agent Collaboration). We excel at trace-based testing and deterministic workflow validation but lack multi-agent communication metrics and production monitoring capabilities.

Overall Alignment Score: 65/100

---

✅ What We're Doing Right

1. Deterministic Workflow Testing ✅ (Best Practice: Section 1, 3)

• What we have: SDK-based execution with real session recording
• Alignment: Perfect match for deterministic multi-agent systems
• Evidence: ServerManager, ClientManager, EventStreamHandler provide full trace capture
• Score: 10/10

Quote from guide:

"Deterministic workflows demand deterministic evaluation... you can now test agent behavior with the same rigor as traditional software"

Our implementation:

// test-runner.ts - Real SDK execution
const result = await this.clientManager.sendPrompt(
  sessionId,
  testCase.prompt,
  { agent: testCase.agent }
);

---

2. Trace-Based Testing ✅ (Best Practice: Trick 5)

• What we have: Event streaming with 10+ events per test
• Alignment: Matches "inspect reasoning chain, not just result" pattern
• Evidence: EventStreamHandler captures tool calls, approvals, context loading
• Score: 9/10

Quote from guide:

"Move beyond output validation to trace validation. Inspect the reasoning chain, not just the result"

Our implementation:

// event-stream-handler.ts
for await (const event of stream) {
  this.events.push({
    type: event.type,
    data: event.data,
    timestamp: Date.now()
  });
}

---

3. Behavior-Based Testing (Not Message Counts) ✅ (Best Practice: Section 2, test-design-guide.md)

• What we have: v2 schema with behavior + expectedViolations
• Alignment: Perfect match for model-agnostic testing
• Evidence: BehaviorExpectationSchema tests tool usage, approvals, delegation
• Score: 10/10

Quote from guide:

"BAD: 'Agent must send exactly 3 messages' GOOD: 'Agent must ask for approval before running bash commands'"

Our implementation:

# v2 schema
behavior:
  mustUseTools: [bash]
  requiresApproval: true

expectedViolations:
  - rule: approval-gate
    shouldViolate: false

---

4. Cost-Aware Testing ✅ (Best Practice: Implicit in production systems)

• What we have: Free model by default (opencode/grok-code-fast)
• Alignment: Prevents accidental API costs during development
• Evidence: CLI --model override, per-test model config
• Score: 8/10

Our implementation:

// test-runner.ts
const model = testCase.model || config.model || 'opencode/grok-code-fast';

---

5. Rule-Based Evaluation ✅ (Best Practice: Section 3.E - Safety & Compliance)

• What we have: 4 evaluators checking openagent.md compliance
• Alignment: Maps to "Policy Compliance" metrics
• Evidence: ApprovalGateEvaluator, ContextLoadingEvaluator, DelegationEvaluator, ToolUsageEvaluator
• Score: 7/10

Quote from guide:

"Policy Compliance: Outputs align with organizational/regulatory constraints - Target: 100% for critical workflows"

Our implementation:

// approval-gate-evaluator.ts
if (toolCall && !hasApprovalRequest) {
  violations.push({
    type: 'approval-gate-missing',
    severity: 'error',
    message: `Tool ${toolCall.name} executed without approval`
  });
}

---

⚠️ What We're Missing (Critical Gaps)

1. Three-Tier Testing Framework ⚠️ (Best Practice: Section 2)

Current State:

• ✅ Tier 2 (Integration): Single-agent multi-step workflows - HAVE THIS
• ❌ Tier 1 (Unit): Tool-level isolation - MISSING
• ❌ Tier 3 (E2E): Multi-agent collaboration - MISSING

Gap Analysis:

Tier	What We Need	What We Have	Gap
Tier 1: Unit	Test individual tools in isolation	Nothing	100% gap
Tier 2: Integration	Single-agent workflows	SDK test runner	✅ Complete
Tier 3: E2E	Multi-agent coordination metrics	Nothing	100% gap

Impact: We can't catch tool failures before agent execution, and we can't measure multi-agent efficiency.

Recommendation:

// NEW: evals/framework/src/unit/tool-tester.ts
export class ToolTester {
  async testTool(toolName: string, params: any, expected: any) {
    const result = await executeTool(toolName, params);
    assert.deepEqual(result, expected);
  }
}

// Example unit test
await toolTester.testTool('fetch_product_price', 
  { productId: '123' },
  { price: 99.99, currency: 'USD' }
);

Score: 3/10 (only have 1 of 3 tiers)

---

2. Multi-Agent Communication Metrics ❌ (Best Practice: Section 3.B - GEMMAS)

What's Missing:

• Information Diversity Score (IDS)
• Unnecessary Path Ratio (UPR)
• Communication efficiency tracking
• Decision synchronization metrics

Quote from guide:

"GEMMAS breakthrough: The Information Diversity Score (IDS) quantifies semantic variation in inter-agent messages. High IDS means agents are exchanging diverse, non-redundant information."

Why This Matters:

"Research from GEMMAS reveals that systems with only a 2.1% difference in task accuracy can differ by 12.8% in Information Diversity Score and 80% in Unnecessary Path Ratio"

Current State: We have NO multi-agent metrics. Our evaluators only check single-agent behavior.

Recommendation:

// NEW: evals/framework/src/evaluators/multi-agent-evaluator.ts
export class MultiAgentEvaluator extends BaseEvaluator {
  async evaluate(timeline: TimelineEvent[]) {
    // Build DAG of agent interactions
    const dag = this.buildInteractionDAG(timeline);
    
    // Calculate IDS (semantic diversity of messages)
    const ids = this.calculateInformationDiversityScore(dag);
    
    // Calculate UPR (redundant reasoning paths)
    const upr = this.calculateUnnecessaryPathRatio(dag);
    
    return {
      ids,
      upr,
      passed: upr < 0.20 // Target: <20% redundancy
    };
  }
}

Score: 0/10 (completely missing)

---

3. LLM-as-Judge Evaluation ⚠️ (Best Practice: Section 4 - DeepEval, G-Eval)

What's Missing:

• Semantic quality scoring
• Hallucination detection
• Answer relevancy metrics
• Faithfulness scoring

Quote from guide:

"DeepEval Metrics: RAGas (Answer Relevancy, Faithfulness, Contextual Precision, Contextual Recall) - Benchmark: 96% faithfulness, 93% relevancy"

Current State: We only have rule-based evaluators. No LLM judges for semantic quality.

Gap: Can't detect:

• Hallucinations (agent making up facts)
• Low-quality responses (technically correct but unhelpful)
• Semantic errors (wrong interpretation of user intent)

Recommendation:

// NEW: evals/framework/src/evaluators/llm-judge-evaluator.ts
export class LLMJudgeEvaluator extends BaseEvaluator {
  async evaluate(timeline: TimelineEvent[], sessionInfo: SessionInfo) {
    const finalResponse = this.extractFinalResponse(timeline);
    
    // G-Eval pattern: LLM generates evaluation steps
    const rubric = await this.generateEvaluationRubric(sessionInfo.prompt);
    
    // Score response against rubric
    const score = await this.scoreWithLLM(finalResponse, rubric);
    
    return {
      score,
      passed: score >= 0.85,
      violations: score < 0.85 ? [{
        type: 'quality-below-threshold',
        severity: 'warning',
        message: `Response quality ${score} below 0.85 threshold`
      }] : []
    };
  }
}

Score: 2/10 (have basic structure, missing LLM judges)

---

4. Production Monitoring & Guardrails ❌ (Best Practice: Trick 6)

What's Missing:

• Real-time scoring on live requests
• Hallucination guards
• Policy violation detection
• Latency guards
• Quality regression alerts

Quote from guide:

"Evals don't stop at deployment. Set up real-time scoring on live requests"

Current State: We only run evals on test cases. No production monitoring.

Recommendation:

// NEW: evals/framework/src/monitoring/guardrails.ts
export class ProductionGuardrails {
  async scoreRequest(sessionId: string) {
    const timeline = await this.getTimeline(sessionId);
    
    // Run evaluators in real-time
    const result = await this.evaluatorRunner.runAll(sessionId);
    
    // Check guardrails
    if (result.violationsBySeverity.error > 0) {
      await this.escalateToHuman(sessionId);
    }
    
    if (result.overallScore < 70) {
      await this.alertQualityRegression(sessionId);
    }
  }
}

Score: 0/10 (completely missing)

---

5. Canary Releases & A/B Testing ❌ (Best Practice: Trick 4)

What's Missing:

• Shadow mode testing
• Gradual rollout (1% → 5% → 50% → 100%)
• Automated rollback on regression
• Feature flag integration

Quote from guide:

"Week 1: Shadow mode - New agent runs in parallel to old agent; compare outputs silently"

Current State: We have no deployment pipeline integration.

Recommendation:

// NEW: evals/framework/src/deployment/canary.ts
export class CanaryDeployment {
  async runShadowMode(newAgent: string, oldAgent: string, duration: number) {
    // Run both agents on same traffic
    const results = await this.runParallel(newAgent, oldAgent, duration);
    
    // Compare metrics
    const drift = this.calculateDrift(results.new, results.old);
    
    // Decision gate
    if (drift.accuracy > 0.05 || drift.latency > 0.10) {
      throw new Error('Shadow mode failed: metrics drifted too much');
    }
  }
}

Score: 0/10 (completely missing)

---

6. Dataset Curation from Production Failures ⚠️ (Best Practice: Trick 7)

What's Missing:

• Automatic logging of failures
• Failure pattern analysis
• Continuous eval dataset updates
• Hard case identification

Quote from guide:

"The best eval datasets aren't lab-created; they come from real agent failures"

Current State: We have static YAML test cases. No feedback loop from production.

Recommendation:

// NEW: evals/framework/src/curation/failure-collector.ts
export class FailureCollector {
  async collectFailures(since: Date) {
    const sessions = await this.sessionReader.getSessionsSince(since);
    
    // Find failures
    const failures = sessions.filter(s => 
      s.userFeedback === 'unhelpful' || 
      s.escalatedToHuman ||
      s.taskSuccess < 0.70
    );
    
    // Convert to test cases
    for (const failure of failures) {
      await this.createTestCase(failure);
    }
  }
}

Score: 2/10 (have test structure, missing automation)

---

7. Benchmark Validation ⚠️ (Best Practice: Section 4 - Bottom table)

What's Missing:

• WebArena (web browsing tasks)
• OSWorld (desktop control)
• BFCL (function calling accuracy)
• MARBLE (multi-agent collaboration)

Quote from guide:

"Top Agentic Benchmarks (2025): WebArena, OSWorld, BFCL, MARBLE"

Current State: We have custom tests but no standard benchmark integration.

Recommendation:

# Add benchmark tests
evals/agents/openagent/benchmarks/
  ├── webarena/
  ├── bfcl/
  └── marble/

Score: 1/10 (have test infrastructure, missing benchmarks)

🎓 Key Learnings from Best Practices Guide

1. Don't Test Message Counts ✅ (We got this right)

"BAD: 'Agent must send exactly 3 messages' GOOD: 'Agent must ask for approval before running bash commands'"

Our v2 schema nails this.

---

2. Multi-Agent Systems Hide Failures ⚠️ (We need to address this)

"A single agent may perform perfectly in isolation but create bottlenecks or miscommunications when collaborating"

We need Tier 3 tests.

---

3. Outcome Metrics Are Insufficient ⚠️ (We need to address this)

"Systems with only a 2.1% difference in task accuracy can differ by 12.8% in Information Diversity Score and 80% in Unnecessary Path Ratio"

We need GEMMAS-style metrics.

---

4. Evals Are Continuous, Not One-Time ❌ (We're missing this)

"Evals don't stop at deployment. Set up real-time scoring on live requests"

We need production monitoring.

---

5. Best Datasets Come from Production ⚠️ (We need to address this)

"The best eval datasets aren't lab-created; they come from real agent failures"

We need automated curation.

---

✅ Conclusion

Current State: We have a solid Tier 2 (Integration Testing) foundation with excellent trace-based testing and behavior validation.

Gaps: We're missing Tier 1 (Unit), Tier 3 (Multi-Agent), LLM-as-Judge, and Production Monitoring.

Recommendation: Follow the 4-phase roadmap to reach 95%+ alignment with best practices.

Immediate Next Steps:

1. Add LLM-as-Judge evaluator (Priority 1)
2. Add unit testing layer (Priority 3)
3. Expand test coverage to 14+ tests (from current 6)

Long-Term Vision:

• Full three-tier testing framework
• Multi-agent communication metrics (GEMMAS)
• Production monitoring with guardrails
• Continuous dataset curation from production failures
