Let me know! If I see that LegacyLens is actually helping you, I’ll be more than happy to dive into the rabbit hole of other languages. Whether it’s Go, Rust, or even C++, I’m ready to start "building" those cities if you’re ready to explore them! 😄</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F2hi83r7vfp38hcbi5rlo.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F2hi83r7vfp38hcbi5rlo.png" alt=" " width="800" height="769"></a></p> <h3> What I want from the community </h3> <p>Since this is my first bigger project, I’d love your honest feedback:</p> <ul> <li>Does the Code City metaphor actually help you understand the codebase faster?</li> <li>How useful is the risk scoring system?</li> <li>Are the AI suggestions practical?</li> <li>What would you improve or add?</li> </ul> <p>Looking forward to your thoughts, ideas, and brutal honesty 😄</p> <p>Thanks for reading!</p> coding ai github programming
