  "Begin by examining the codebase structure to identify technologies:
   - Check for .NET solutions/projects, Spring configurations, Node.js/Express files, etc.
   - Identify the primary programming language(s) and frameworks in use
   - Determine the architectural patterns based on folder structure and key components"

Implementation Guidelines

Based on the documented workflows, provide specific guidance for implementing new features:

1. Step-by-Step Implementation Process

• Where to start when adding a similar feature
• Order of implementation (e.g., model → repository → service → controller)
• How to integrate with existing cross-cutting concerns

2. Common Pitfalls to Avoid

• Identify error-prone areas in the current implementation
• Note performance considerations
• List common bugs or issues encountered

3. Extension Mechanisms

• Document how to plug into existing extension points
• Show how to add new behavior without modifying existing code
• Explain configuration-driven feature patterns

Conclusion: Conclude with a summary of the most important patterns that should be followed when implementing new features to maintain consistency with the codebase."
