Codex Image Generation

Generate images through Codex's built-in image_gen tool. Do not invent a codex image subcommand: Codex image generation is agentic and is invoked through codex or codex exec.

Choose the execution path

If this agent already has the built-in image_gen tool, use it directly. Do not recursively start another Codex session.
Otherwise, invoke codex exec and explicitly tell the child agent to use its built-in imagegen skill and image_gen tool.

Both paths use Codex's ChatGPT authentication and do not require OPENAI_API_KEY. Never silently switch to the Image API, the openai CLI, or an SDK script.
