Nick Perry explains how Claude breaks unrelated code when editing single files without seeing the full codebase. Git Nexus, a free tool, maps dependencies across files so Claude understands the context and stops creating cascading failures.

Never ever build an app with Claude until you know this, because the bigger your project gets, the more it quietly breaks things you never touch. See, Claude finally made it so anyone can build real software, like a CRM or lead dashboard that used to need a developer. But the second your project gets real, Claude only sees the file it's editing, not the rest of your project. So you ask it to add a feature and it breaks the login. But when you ask it to fix that, It breaks the dashboard. That's what Git Nexus fixes because it scans your whole project and maps how every piece connects. Then it hands that map to Claude so Claude knows what it's working on and stops breaking things, which means you keep building without hiring an engineer to fix this mess. Comment Nexus and I'll send the guide.
