+# 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:**
|
|
|
+```typescript
|
|
|
+// 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:**
|
|
|
+```typescript
|
|
|
+// 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:**
|
|
|
+```yaml
|
|
|
+# 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:**
|
|
|
+```typescript
|
|
|
+// 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:**
|
|
|
+```typescript
|
|
|
+// 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:**
|
|
|
+```typescript
|
|
|
+// 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:**
|
|
|
+```typescript
|
|
|
+// 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:**
|
|
|
+```typescript
|
|
|
+// 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:**
|
|
|
+```typescript
|
|
|
+// 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);
|
|
|

|
|
|
+
|
|
|
+### 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
|
|
|
+
|

|
|
+> "Week 1: Shadow mode - New agent runs in parallel to old agent; compare outputs silently"
|
|
|
+
|
|
|
+**Current State:** We have no deployment pipeline integration.
|
|

+
|
|
|
+**Recommendation:**

|
|
+
|
|
|
+### 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
|
|
|
+
|

|
|
+### **Priority 1: Add LLM-as-Judge Evaluators** (High Impact, Medium Effort)
|
|
|
+**Why:** Catches semantic errors our rule-based evaluators miss
|
|
|
+**Effort:** 2-3 days
|
|
|
+**Impact:** +15% coverage
|
|
|
+
|
|
|
+**Implementation:**
|
|
|
+```typescript
|
|
|
+// evals/framework/src/evaluators/llm-judge-evaluator.ts
|
|
|
+import { BaseEvaluator } from './base-evaluator.js';
|
|
|
+
|
|
|
+export class LLMJudgeEvaluator extends BaseEvaluator {
|
|
|
+ name = 'llm-judge';
|
|
|
+
|
|
|
+ async evaluate(timeline, sessionInfo) {
|
|
|
+ // Use G-Eval pattern
|
|
|
+ const rubric = this.generateRubric(sessionInfo.prompt);
|
|
|
+ const score = await this.scoreWithLLM(timeline, rubric);
|
|
|
+
|
|
|
+ return {
|
|
|
+ evaluator: this.name,
|
|
|
+ passed: score >= 0.85,
|
|
|
+ score: score * 100,
|
|
|
+ violations: []
|
|
|
+ };
|
|
|
+ }
|
|
|
+}
|
|
|
+```
|
|
|
+
|

|
|
|
+
|
|
|
+### **Priority 2: Add Multi-Agent Communication Metrics** (High Impact, High Effort)
|
|
|
+**Why:** Critical for multi-agent systems (80% efficiency difference per GEMMAS)
|
|
|
+**Effort:** 1 week
|
|
|
+**Impact:** +20% coverage
|
|
|
+
|
|
|
+**Implementation:**
|
|
|
+```typescript
|
|
|
+// evals/framework/src/evaluators/multi-agent-evaluator.ts
|
|
|
+export class MultiAgentEvaluator extends BaseEvaluator {
|
|
|
+ name = 'multi-agent';
|
|
|
+
|
|
|
+ async evaluate(timeline, sessionInfo) {
|
|
|
+ const dag = this.buildInteractionDAG(timeline);
|
|
|
+ const ids = this.calculateIDS(dag); // Information Diversity Score
|
|
|
+ const upr = this.calculateUPR(dag); // Unnecessary Path Ratio
|
|
|
+
|
|
|
+ return {
|
|
|
+ evaluator: this.name,
|
|
|
+ passed: upr < 0.20,
|
|
|
+ score: (1 - upr) * 100,
|
|
|
+ violations: upr >= 0.20 ? [{
|
|
|
+ type: 'high-redundancy',
|
|
|
+ severity: 'warning',
|
|
|
+ message: `UPR ${upr} exceeds 20% threshold`
|
|
|
+ }] : []
|
|
|
+ };
|
|
|
+ }
|
|
|
+}
|
|
|
+```
|
|
|
+
|
|

|
|
|
+
|
|
|
+### **Priority 3: Add Unit Testing Layer (Tier 1)** (Medium Impact, Low Effort)
|
|
|
+**Why:** Catches tool failures before agent execution
|
|
|
+**Effort:** 1-2 days
|
|
|
+**Impact:** +10% coverage
|
|
|
+
|
|
|
+**Implementation:**
|
|
|
+```typescript
|
|
|
+// evals/framework/src/unit/tool-tester.ts
|
|
|
+export class ToolTester {
|
|
|
+ async testTool(toolName: string, params: any, expected: any) {
|
|
|
+ const result = await this.executeTool(toolName, params);
|
|
|
+
|
|
|
+ if (!this.deepEqual(result, expected)) {
|
|
|
+ throw new Error(`Tool ${toolName} failed: expected ${expected}, got ${result}`);
|
|
|
+ }
|
|
|
+ }
|
|
|
+}
|
|
|
+
|
|
|
+// Usage in tests
|
|
|
+await toolTester.testTool('bash', { command: 'echo hello' }, { stdout: 'hello\n' });
|
|
|
+```
|
|
|
+
|
|
|
+---
|
|
|
+
|
|
|
+### **Priority 4: Add Production Monitoring** (High Impact, High Effort)
|
|
|
+**Why:** Evals don't stop at deployment
|
|
|
+**Effort:** 1 week
|
|
|
+**Impact:** +15% coverage
|
|
|
+
|
|
|
+**Implementation:**
|
|
|
+```typescript
|
|
|
+// evals/framework/src/monitoring/production-monitor.ts
|
|
|
+export class ProductionMonitor {
|
|
|
+ async monitorSession(sessionId: string) {
|
|
|
+ const result = await this.evaluatorRunner.runAll(sessionId);
|
|
|
+
|
|
|
+ // Guardrails
|
|
|
+ if (result.violationsBySeverity.error > 0) {
|
|
|
+ await this.escalateToHuman(sessionId);
|
|
|
+ }
|
|
|
+
|
|
|
+ // Quality regression
|
|
|
+ if (result.overallScore < this.baseline - 5) {
|
|
|
+ await this.alertRegression(sessionId, result.overallScore);
|
|
|
+ }
|
|
|
+ }
|
|
|
+}
|
|
|
+```
|
|
|
+
|
|
|

|
|
|
+
|
|
|
+### **Priority 5: Add Dataset Curation Pipeline** (Medium Impact, Medium Effort)
|
|
|
+**Why:** Continuous improvement from production failures
|
|
|
+**Effort:** 3-4 days
|
|
|
+**Impact:** +10% coverage
|
|
|
+
|
|
|
+**Implementation:**
|
|
|
+```typescript
|
|
|
+// evals/framework/src/curation/auto-curator.ts
|
|
|
+export class AutoCurator {
|
|
|
+ async curateFromProduction(since: Date) {
|
|
|
+ const failures = await this.collectFailures(since);
|
|
|
+
|
|
|
+ for (const failure of failures) {
|
|
|
+ const testCase = this.convertToTestCase(failure);
|
|
|
+ await this.saveTestCase(testCase);
|
|
|
+ }
|
|
|

+## 🎓 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
