Which isn't particularly difficult - the language docs and std source come with the installation, so all you need to do is tell Claude where those directories are in your skill/plugin/CLAUDE.md.

It does struggle sometimes with writing code that compiles and uses the APIs correctly. My approach to that so far has been to write test blocks describing the desired interface + semantics, and asking Claude to (`zig test` -> fix errors) in a loop until all the tests pass.
You're already at a disadvantage having to stuff the context and spend extra tokens coercing the model in the correct direction compared to it already knowing what to do (rust, ts, go, etc.)
Here, I just did a quick test with claude.
1. "make a simple tcp echo server that uses rust"
compiles and runs - took a few seconds to generate.
2. "make a simple tcp echo server that uses zig"
result: compile error, took literal minutes of spinning and thinking to generate
response: "ziglang.org isn't in the allowed domains. Let me check if there's another way, or just verify the code compiles conceptually and present it clean."

3. "make a simple tcp echo server that uses zig 0.16"
result: compile error:

4. "make a simple tcp echo server that uses zig 0.15"
result: compile error

Rust took seconds and just works. Zig examples took minutes and don't work out of the box. The DX & velocity isn't even close.
