Are you using Claude Code? Do yo have it configured so that you are not allowing it to run the build? Because I've observed that Claude Code is extremely good at making sure the code compiles, because it'll run a compile and address any compile errors as part of the work.

I just asked it to build a TOML example program in DotNet using Tomlyn, and when it was done I was able to run "./bin/Debug/net8.0/dotnettoml example.toml", it had already built it for me (I watched it run the build step as part of its work, as I mentioned it would do above).

I am using Claude code. I didn’t explicitly tell it what the build command was (it’s dotnet build), and it didn’t ask. Thats not my fault.

My observation is that it’s fine until it’s absolutely not, and the agentic loop fails.

		>Thats not my fault. I don't know that it's useful to assign blame here. It probably is to your benefit, if you are a coding professional, to understand why your results are so drastically different from what others are seeing. You started this thread saying "I keep getting told I'll be amazed at what it can do, but the tools keep failing at the first hurdle." I'm telling you that something is wrong, that is why you are getting poor results. I don't know what is wrong, but I've given you an example prompt and an example output showing that Claude Code is able to produce the exact output you were looking for. This is why a lot of people are saying "you'll be amazed at what it can do", and it points to you having some issue. I don't know if you are running an ancient version of Claude Code, if you are not using Opus 4.6, you are not using "high" effort (those are what I'm using to get the results I posted elsewhere in reply to your comment), but something is definitely wrong. Some of what may be wrong is that you don't have enough experience with the tooling, which I'd understand if you are getting poor results; you have little (immediate) incentive to get more proficient. As I said, I was able to tell Claude Code to do something like the example you gave, and it did it and it built, without me asking, and produced a working program on the first try.
