Use the img-gen CLI from @hewliyang/codex-image-cli to generate or edit raster images via the user's ChatGPT Codex OAuth token. Trigger for photos, illustrations, textures, sprites, mockups, hero images, product shots, visual variants, image edits, or transparent-background bitmap assets.

Use the generate_image tool to create or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, hero images, or transparent-background cutouts. Triggers include requests to make a new image from a text description, transform or restyle an existing image, derive variants from references, or produce graphical assets for websites, games, decks, or marketing.
