When I tried to use the $image-pen command to draw an image, Codex told me that this tool was not available. But in the skills documentation, I saw this:
“This skill has exactly two top-level modes:
Default built-in tool mode (preferred): built-in image_gen tool for normal image generation, editing, and simple transparent-image requests. Does not require OPENAI_API_KEY.
Fallback CLI mode: scripts/image_gen.py CLI. Use when the user explicitly asks for the CLI/API/model path, or after the user explicitly confirms a true model-native transparency fallback with gpt-image-1.5. Requires OPENAI_API_KEY.”
So I’m a bit confused: what exactly is the image-pen tool?
