Declare OpenAI inference support.
CodexAgent inherits supported_inference(), which returns an empty vector. src/main.rs::run therefore rejects --agent codex --inference openai before building an image. Every new positive Codex image test uses this combination. Override the method to return only InferenceKind::OpenAi. (raw.githubusercontent.com)
Proposed fix
impl Agent for CodexAgent {
+ fn supported_inference(&self) -> Vec<crate::inference::InferenceKind> {
+ vec![crate::inference::InferenceKind::OpenAi]

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Implement model configuration.
After OpenAI support is enabled, --model gpt-4o --with-agent-settings still cannot generate the required model settings. The inherited set_inference() returns its input unchanged. With no settings directory, src/main.rs::stage_agent_settings stages nothing. Implement set_inference() to write the model into .codex/config.toml while preserving existing settings.

Implement the endpoint environment variable.
After OpenAI support is enabled, --endpoint still leaves OPENAI_BASE_URL unset because the inherited env_vars() returns an empty map. src/main.rs::run uses that map for image environment variables but separately applies the endpoint to network policy. Implement env_vars() to emit the configured OpenAI endpoint, including the repository’s localhost rewrite. (raw.githubusercontent.com)

Match the policy assertion to the generated policy.
After OpenAI builds are enabled, all four policy_has_codex_rules tests still fail here. CodexAgent::policy_yaml() returns an empty string, and the OpenAI inference policy emits name: openai, not name: codex. Check that the OpenAI rule authorizes the Codex binary instead of requiring an unimplemented agent-specific rule. (raw.githubusercontent.com)
