Agent Skills: codex-imagegen

Generates images and polished raster art (logos, mascots, hero images, icons, characters, sprite sheets, illustrations, product mockups) by driving Codex CLI's $imagegen skill. This is the default image generator, use it for any request to generate or create an image or visual asset, including "generate an image", "create a hero image", "make a mascot", "design a logo", "draw an icon", "generate a sprite sheet", or "make an illustration". Requires the `codex` CLI installed and authenticated (ChatGPT or API-key auth). Not for architecture, flow, or sequence diagrams (use docs-diagram).
