I recorded Claude fix two MiniJinja issues itself. It's Rust (which it sucks at), in a code base not really set up for vibe coding and it still succeeds. Yes, it takes 30 minutes, but it's hands off. Usually I let this work alone and review later.

I also have the video on youtube:

Honestly, I’m kinda ready to say they don’t actually suck at Rust anymore haha. I’ve given them way too many problems I was sure they’d fail at and they solved it without issue. Now that they iterate with diagnostics feedback, Rust is actually ideal imo

Well you can see that it struggles with tool usage and the borrow checker. Clearly skill issue ;)

non-stop code review fuuuck me😄🔫

claude's rust win shows automated fixes work, but for markets i still need proof before trusting moves.

This is very much my workflow! I think it works very well when you are familiar with the project and you can zoom through the diffs, but I still having a hard time relying on Claude to write new features because it’s harder for me to fully wrap my mind around the code change. I wonder if your experience with open-source projects with multiple contributors helps. I also think that the approach of discussing the bug in detail is a very useful pattern for AI-based work, because it helps the human understand what the AI should generate. I’d argue that the support for different languages and tooling will only get better over time and the quality of the code will only improve. However, it also seems that having an easy way to run a test and the entire test suite is more and more important. The same when it comes to using the right abstractions. I do wonder if the human programmer will shift towards creating the correct context for the AI agent.

New features on new projects works well if you structure them for agentic workflows but it requires quite a bit of attention. I’m sure this will get better soon but today there are some things you can do to improve the success of such things. I went super deep on Claude recently and found a lot of success on new projects. After talking to @zeeg I also want to see how well Cursor’s background agents work. That might work actually better for existing projects right now because the is quite good at following rules.

What was the cost of 30 minutes?

I pay a flat rate.

All AIs suck at Rust. I don’t think it’s the AIs’ fault.
