This one needs environment variables set before it will start: CODEX_API_KEY (OpenAI API key (leave unset to inherit from parent process)), CODEX_TOOL_NAME (Tool name prefix (default: codex)), CODEX_MODEL (Model: gpt-5-codex, o3, codex-1, or full ID), CODEX_SANDBOX_MODE (Sandbox: read-only, workspace-write, danger-full-access), CODEX_APPROVAL_POLICY (Approval: never, on-failure, on-request, untrusted), CODEX_APPEND_INSTRUCTIONS (Additional instructions appended to the default), CODEX_FACTORY_ONLY (Set to true to expose only the factory wizard tool). The author declared them in the registry entry; get the values from the project itself.
