i tested sonnet 4.5 just last week on a zig codebase and it has to be instructed the std.ArrayList syntax every time.

I made a Zig agent skill yesterday if interested: https://github.com/rudedogg/zig-skills/

Claude getting the ArrayList API wrong every time was a major reason why

It’s AI generated but should help. I need to test and review it more (noticed it mentions async which isn’t in 0.15.x :| )

The linked blog post about making this is an excellent read.

Thanks! I think I spent as much time writing the post as I did making the skill, so I’m happy someone got some value out of it.

A little bit! I wrote a long blog post about how I made it, I think the strategy of having an LLM look at individual std modules one by one make it actually pretty accurate. Not perfect, but better than I expected

Try it again. This time do something different with CLAUDE.md. By the way it's happy to edit its own CLAUDE.md files (don't have an agent edit another agent's CLAUDE.md files though [0])

Are you using an agent? It can quickly notice the issue and fix it. Obviously if it's trained on an older version it won't know the new APIs.
