Crate codex_commit 

Restricted, generation-only commit messages from caller-supplied public diffs. No repository discovery or Git operations are performed. Unix only.

Paths and model are explicit. Only the current access credentials are copied; source OAuth refresh credentials, user configuration and instructions are never passed to the generation process. Expired credentials require source CLI reauthentication. Generation never writes back to the source authentication home.

use codex_commit::{generate_message, GenerationOptions, GenerationRequest};
let options = GenerationOptions::new(
    "/absolute/path/to/codex".into(),
    "/absolute/path/to/auth-home".into(),
    "gpt-6.1-sol".into(),
);
let message = generate_message(GenerationRequest { diff: "public diff" }, &options)?;
let rendered = message.render()?;
