Before you can fix a bug or add a feature, you have to answer questions like:</p> <ul> <li>Which files actually matter?</li> <li>Where is the real entry point?</li> <li>Which modules are safe to ignore?</li> <li>Where does the technical debt live?</li> <li>How is everything connected?</li> </ul> <p>I've wasted enough time doing that manually that I decided to build a tool for it.</p> <h2> Introducing Project MRI </h2> <p>Project MRI analyzes a project ZIP and generates an onboarding guide for engineers. Instead of dumping you into a giant file tree, it tries to answer the questions you'd normally spend hours figuring out yourself.</p> <p>It currently highlights:</p> <ul> <li>📍 The first files you should read</li> <li>🗺️ A high-level architecture overview</li> <li>⚠️ Technical debt and risk hotspots</li> <li>📊 A repository health score</li> <li>⏱️ An estimate of how quickly someone can become productive</li> </ul> <p>The goal isn't to replace your IDE or AI coding assistant. It's to solve the "where do I start?" problem.</p> <h2> Why I built it </h2> <p>Every time I joined a new project or came back to an old one, I found myself clicking through directories hoping to discover the important pieces.</p> <p>I wanted something that could point me in the right direction immediately instead of making me reverse-engineer the repository from scratch.</p> <h2> Looking for honest feedback </h2> <p>I'm still actively improving it and would love input from engineers who work on large or legacy codebases.</p> <p>Some questions I'm especially interested in:</p> <ul> <li>Would something like this actually save you time?</li> <li>What's the first insight you'd want after uploading a repository?</li> <li>What would make this genuinely useful in your day-to-day workflow?</li> </ul> <p>If you'd like to try it, it's available here:</p> <p><strong><a href="https://projectmri.com" rel="noopener noreferrer">https://projectmri.com</a></strong></p> <p>I'm not looking for compliments—I want to know what's confusing, missing, or not valuable enough to use.</p> productivity showdev softwareengineering tooling
