Fix: Quality Analyze Context Field Error

Issue Summary

Error: Cannot read properties of undefined (reading 'context') Location: src/mcp/handlers/quality-analyze.ts:293-310 Root Cause: The dataSource.context field was being accessed but not provided in the MCP tool call parameters.

Problem Analysis

The error occurred when the quality_analyze MCP tool was called without a context field in the dataSource parameter:

mcp__agentic_qe__quality_analyze({
  params: {
    scope: "code",
    metrics: ["complexity", "maintainability", "technical_debt"],
    generateRecommendations: true,
    historicalComparison: false,
    thresholds: {
      cyclomatic_complexity: 20,
      cognitive_complexity: 100,
      lines_of_code: 1000
    }
  },
  dataSource: {
    codeMetrics: {
      files: [
        {name: "SwarmMemoryManager.ts", loc: 1838, cyclomatic: 187, severity: "critical"}
      ]
    }
    // ❌ Missing: context field
  }
})

The QualityGateAgent expected a required context field with deploymentTarget, criticality, changes, and environment properties, but it was not being provided.

Solution

1. Updated QualityAnalyzeArgs Interface

Made the context field optional in the dataSource parameter:

export interface QualityAnalyzeArgs {
  params: QualityAnalysisParams;
  dataSource?: {
    testResults?: string;
    codeMetrics?: string | any; // Allow object for structured metrics
    performanceData?: string;
    context?: {  // ✅ Made optional
      deploymentTarget?: 'development' | 'staging' | 'production';
      criticality?: 'low' | 'medium' | 'high' | 'critical';
      environment?: string;
      changes?: any[];
    };
  };
}

2. Added Default Context in Handler

Modified the quality-analyze handler to provide default context when missing:

// Ensure dataSource has a default context if missing
const dataSourceWithContext = args.dataSource ? {
  ...args.dataSource,
  context: args.dataSource.context || {
    deploymentTarget: 'development' as const,
    criticality: 'medium' as const,
    environment: process.env.NODE_ENV || 'development',
    changes: []
  }
} : {
  context: {
    deploymentTarget: 'development' as const,
    criticality: 'medium' as const,
    environment: process.env.NODE_ENV || 'development',
    changes: []
  }
};

3. Updated QualityGateAgent Interface

Made all context fields optional in QualityGateRequest:

export interface QualityGateRequest {
  testResults: QETestResult[];
  metrics: QualityMetrics;
  context?: {  // ✅ Made optional
    deploymentTarget?: 'development' | 'staging' | 'production';
    criticality?: 'low' | 'medium' | 'high' | 'critical';
    changes?: Array<{
      file: string;
      type: 'added' | 'modified' | 'deleted';
      complexity: number;
    }>;
    environment?: string;
  };
  customCriteria?: QualityCriterion[];
}

4. Added Safe Context Access in QualityGateAgent

Added defensive checks and default values throughout the agent:

// Provide default context if missing
const context = request.context || {
  deploymentTarget: 'development' as const,
  criticality: 'medium' as const,
  changes: [],
  environment: process.env.NODE_ENV || 'development'
};

// Safe access in methods
const criticality = context?.criticality || 'medium';
const deploymentTarget = context?.deploymentTarget || 'development';
const changes = context?.changes || [];
const environment = context?.environment || 'development';

Files Modified

1. /workspaces/agentic-qe-cf/src/mcp/handlers/quality-analyze.ts

   • Updated QualityAnalyzeArgs interface (lines 17-30)
   • Added default context logic (lines 301-317)

2. /workspaces/agentic-qe-cf/src/agents/QualityGateAgent.ts

   • Updated QualityGateRequest interface (lines 17-31)
   • Added default context in evaluateQualityGate (lines 192-198)
   • Added safe access in calculateDynamicThreshold (lines 357-372)
   • Added safe access in analyzeRiskFactors (lines 389-406)

Testing

Verified the fix with the exact parameters from the original error:

const testParams = {
  params: {
    scope: "code",
    metrics: ["complexity", "maintainability", "technical_debt"],
    generateRecommendations: true,
    historicalComparison: false,
    thresholds: {
      cyclomatic_complexity: 20,
      cognitive_complexity: 100,
      lines_of_code: 1000
    }
  },
  dataSource: {
    codeMetrics: {
      files: [
        {name: "SwarmMemoryManager.ts", loc: 1838, cyclomatic: 187, severity: "critical"}
      ]
    }
    // ✅ No context field - should now work with defaults
  }
};

Result: ✅ Fix verified - context is now provided with defaults when missing.

Backward Compatibility

✅ Fully backward compatible

• Existing code that provides context will continue to work
• New code can omit context and use defaults
• No breaking changes to interfaces or behavior

Impact

• Fixes: Critical runtime error preventing quality analysis
• Improves: Robustness by handling missing optional parameters
• Enables: Quality analysis to run with minimal required parameters
