Apologies, but your information is either outdated from lack of experience with the latest frontier models, or you don't realize the fact that 99.9% of the work you do is not novel in all capacities. Have you only used Copilot, or something? Because that's what it sounds like. Since the performance of the latest models (Opus 4.6 max-effort, gpt-5.3-Codex) is nothing short of astonishing.

Real-world example: Claude isn't familiar with the latest Zig, so I had it write a language guide for 0.15.2 (here: https://gist.github.com/pmarreck/44d95e869036027f9edf332ce9a...) which pointed out all the differences, and that's been extremely helpful in having me not even have to touch a line of code to do the updates.

On top of that, for any Zig dependency I pull in which is written to an earlier version, I have forked it and applied these updates correctly (or it has, under my guidance, really), 100% of the time.

On the off chance that guide is not in its context, it has seen the expected warning or error message, googled it, and done the correct correction 100% of the time. Which is exactly what a human would do.

Let's play the falsifiability game: Find me a real-world example of an upgrade to a newer API from the just-previous-to-that API that a modern LLM will fail to do correctly. Your choice of beer or coffee awaits you if you provide a link to it.

Tbh, while impressive that it appears to work, that guide looks very tailored to the Zig stdlib subset used in your projects and also looks like a lot more work than just fixing the errors manually ;) For a large code base which would amortise the cost of this guide I still wouldn't trust the automatic update without carefully reviewing each change.

I’ve been making a project in zig 0.16 with Claude as a learning experiment. It’s a fairly non trivial project (BitTorrent compliant p2p downloader for model weights on top of huggingface xet) - whenever it doesn’t know the syntax or makes errors, it literally reads the standard library code to understand and fix it. The project works too!
