I’ve been using Claude Code for a while now. There’s no doubt it’s incredibly powerful, but there’s one thing that has always annoyed me: the way it reads files is far too crude and aggressive.
When you ask it to modify a function, it first reads the entire file. Then it discovers that a dependency is in another file, so it reads that one too. After reading it, it realizes it needs to see the definition of a certain class, so it reads a third file.
For a simple request, it ends up reading three or four entire files. Tokens just pour out. On top of that, with OpenAI cutting three products in a week and Claude once again tightening its usage limits, it feels like the good days of AI are coming to an end. Even the $20 official subscription is often used up after just a couple of sessions.
Actually, this isn’t really a problem with Claude Code specifically—it’s a common disease shared by almost all AI coding agents.
Agents have no concept of a project directory structure. Their default action is: Not sure? Read the file. Still not sure? Read another one.
Recently, I discovered a tool called cx that’s specifically designed to solve this problem. After using it, the results have been excellent, so I’m sharing it with everyone.
