• Context Awareness: Distinguishes between technical and business content
• Violation Detection: Identifies areas for improvement with suggestions

Code Quality Validation

• Programming Standards: Checks for hardcoded values and poor practices
• Maintainability: Validates function length, complexity, and structure
• Configuration: Ensures proper externalization of settings
• Best Practices: Enforces clean code principles

Data Integrity Verification

• Claim Validation: Verifies numerical claims against source data
• Source Tracking: Automatically detects latest validation files
• Metrics Verification: Ensures accuracy of performance claims
• Reference Management: Maintains data source documentation

⚙️ Configuration & Standards

Universal System Prompts (config/universal_system_prompts.yaml)

• Centralized Configuration: Single file for validation rules and standards
• Industry Standards: Based on established software engineering practices
• Flexible Framework: Designed for easy extension and modification
