# QC System Debug Report - Option C **Date:** 2025-10-17 **Issue:** Execution report claims success when QC never ran **Status:** 🔍 ROOT CAUSE IDENTIFIED --- ## Debugging Process ### Step 1: Check Execution Report **File:** `generated-agents/execution-report.md` **Claims:** - "All three tasks were executed **without failures**" - "Success. Produced a full architecture diagram..." - "Success. Delivered a detailed module breakdown..." - "Success. Produced a thorough risk, regulatory..." **Reality:** No QC verification happened! --- ### Step 2: Check Graph Storage **Query:** Search for task execution nodes ```javascript memory_search_nodes('Task Execution') // Result: "No results" ``` **Finding:** ❌ Despite execution report claiming "Output stored in graph node", the `storeTaskResultInGraph` function was NOT successfully called, OR the graph is being cleared between runs. --- ### Step 3: Code Analysis - executeTask Function **File:** `src/orchestrator/task-executor.ts:302-383` ```typescript async function executeTask( task: TaskDefinition, preamblePath: string ): Promise<ExecutionResult> { // ... setup ... try { // 1. Initialize WORKER agent const agent = new CopilotAgentClient({ preamblePath, model: model, temperature: 0.0, }); // 2. Execute WORKER with task prompt const result = await agent.execute(task.prompt); // 3. IMMEDIATELY mark as SUCCESS (❌ NO QC CHECK!) const executionResult: Omit<ExecutionResult, 'graphNodeId'> = { taskId: task.id, status: 'success', // ❌ WRONG - Should be 'awaiting_qc' output: result.output, // ... other fields }; // 4. Store in graph const graphNodeId = await storeTaskResultInGraph(task, executionResult); // 5. Return success (❌ QC NEVER INVOKED!) return { ...executionResult, graphNodeId, }; } catch (error: any) { // ... error handling ... } } ``` --- ## ROOT CAUSE IDENTIFIED ### 🚨 CRITICAL BUG **Line 340:** `status: 'success'` The `executeTask` function **ALWAYS** marks tasks as `'success'` after worker execution, **SKIPPING** the entire QC verification flow. **What SHOULD happen:** 1. Execute worker → mark as `'awaiting_qc'` 2. Execute QC agent → check verification 3. If QC passes → mark as `'success'` 4. If QC fails → mark as `'pending'`, retry with feedback 5. After retries exhausted → mark as `'failed'`, generate reports **What ACTUALLY happens:** 1. Execute worker → mark as `'success'` ✅ DONE (QC skipped entirely!) --- ## Why Execution Report Claims Success **File:** `src/orchestrator/task-executor.ts:502-670` (generateFinalReport) The `generateFinalReport` function: 1. Reads `ExecutionResult[]` array 2. Filters by `status === 'success'` or `status === 'failure'` 3. Since ALL results have `status: 'success'`, it reports them as successful 4. Invokes PM agent to "summarize" the (hallucinated) outputs 5. PM agent, having no context of QC failures, writes a positive report **The PM agent is doing its job correctly** - it's summarizing what it sees. The problem is that it sees `status: 'success'` for all tasks, so it assumes everything went well! --- ## Missing Code Sections ### ❌ Missing: QC Role Parsing **Current `parseChainOutput` (lines 1-186):** - ✅ Extracts `agentRoleDescription` (worker) - ✅ Extracts `recommendedModel` - ✅ Extracts `optimizedPrompt` - ✅ Extracts `dependencies` - ✅ Extracts `estimatedDuration` - ❌ Does NOT extract `qcRole` - ❌ Does NOT extract `verificationCriteria` - ❌ Does NOT extract `maxRetries` **Result:** Even though `chain-output.md` contains QC roles, they're never parsed! --- ### ❌ Missing: QC Preamble Generation **Current preamble generation (lines 420-432):** ```typescript // Generate preambles for each unique role for (const [role, roleTasks] of roleMap.entries()) { console.log(`📝 Role (${roleTasks.length} tasks): ${role.substring(0, 60)}...`); const preamblePath = await generatePreamble(role, outputDir); rolePreambles.set(role, preamblePath); } ``` **Observation:** Only WORKER roles are in `roleMap` because only worker roles are extracted during parsing. QC roles are never added to the map! **Result:** No QC preambles are generated, so QC agents can't be invoked. --- ### ❌ Missing: QC Agent Execution **Current `executeTask` (lines 287-383):** - ✅ Loads worker preamble - ✅ Executes worker agent - ✅ Stores result - ❌ Does NOT check if task has QC role - ❌ Does NOT execute QC agent - ❌ Does NOT implement retry logic - ❌ Does NOT generate failure reports **Result:** Worker output is immediately marked as success, no verification. --- ### ❌ Missing: Retry Logic **Current code:** No retry loop exists in `executeTask`. **Expected:** ```typescript while (attemptNumber <= maxRetries) { // Execute worker // Execute QC // If QC passes, return success // If QC fails, increment attemptNumber and retry } // Generate failure report ``` **Result:** Workers never get a second chance, and failures are never reported. --- ### ❌ Missing: Failure Reporting **Current code:** - No `generateQCFailureReport` function - No `buildPMFailureSummaryPrompt` function - `generateFinalReport` only handles success cases **Result:** Even if failures occurred, no reports would be generated. --- ## Summary of Findings | Component | Status | Impact | |-----------|--------|--------| | **QC Role Parsing** | ❌ Not Implemented | QC roles in markdown are ignored | | **QC Preamble Generation** | ❌ Not Implemented | No QC agents can be invoked | | **QC Agent Execution** | ❌ Not Implemented | Worker output never verified | | **Retry Logic** | ❌ Not Implemented | No second chances for workers | | **QC Failure Reporting** | ❌ Not Implemented | Failures not documented | | **PM Failure Summary** | ❌ Not Implemented | No strategic analysis of failures | | **Graph Storage** | ⚠️ Partial | Works but stores wrong status | --- ## Why Tests Passed But Production Failed **Test file:** `testing/qc-verification-workflow.test.ts` **Tests verify:** - ✅ `ContextManager` filtering (works correctly) - ✅ Graph node updates (works correctly) - ✅ QC verification data structure (correct) **Tests DO NOT verify:** - ❌ Task executor actually invoking QC agents - ❌ End-to-end flow from parsing → execution → QC → retry - ❌ Integration between task executor and QC system **Result:** Unit tests pass because individual components work. Integration tests don't exist, so the missing wiring went undetected. --- ## Next Steps (Option A Implementation) Based on this debugging, Option A must implement: 1. **Parsing:** Extract `qcRole`, `verificationCriteria`, `maxRetries` from markdown 2. **Preamble Generation:** Generate QC preambles alongside worker preambles 3. **Execution Loop:** Rewrite `executeTask` to implement Worker → QC → Retry 4. **QC Prompts:** Create `buildQCPrompt` and `parseQCResponse` functions 5. **Failure Reporting:** Create `generateQCFailureReport` function 6. **PM Summary:** Update `generateFinalReport` to handle failures 7. **Integration Tests:** Create `testing/qc-execution-integration.test.ts` **Estimated Implementation Time:** 4-6 hours (per Option B plan) --- **Status:** 🔍 DEBUG COMPLETE - Ready for Option A implementation **Priority:** P0 - Critical security/quality feature completely missing **Impact:** Hallucinations pass as production output with zero verification
