Could you provide more details about the bug you're seeing? What is the problem?

Codex does work with a local ollama server and gpt-oss. If you're having problems, it's most likely a configuration issue.

Please refer to this documentation for additional details.

• Updated Plan
└ □ Create minimal test for config default value
□ Run current tests to see failure
□ Implement missing functionality if needed

• Answer

libcore is automatically available when you compile a library or binary with #[no_std].
You don’t need a use statement for it.

What to do next

1. Remove the use_std line from Cargo.toml.

[lib]
# use_std = true <-- delete this

1. Add #[no_std] to the root of your crate (e.g., in src/lib.rs or src/main.rs):

#![no_std]

1. If you want to refer to items in the core library, use the core:: prefix directly, e.g., core::fmt::Write.

With those two changes, libcore will be in scope automatically, and you can use all the primitives it provides. Let me
know if you’d like me to add any other setup or run the compiler to confirm it works.
