Setup & Installation
What This Skill Does
Generates and edits raster images inside a Codex session. Works with photos, illustrations, textures, UI mockups, product shots, and transparent-background cutouts. Uses a built-in tool by default; a CLI fallback using the OpenAI API is available when explicitly requested.
Instead of context-switching to a separate image tool and re-describing the project, you can generate and iterate on assets in the same session where the code lives.
When to use it
- Generating a hero image for a landing page with usable negative space for copy
- Replacing a product photo background while keeping the product unchanged
- Producing multiple icon variants or sprite sheets for a game in one session
- Creating a UI mockup or wireframe at a specified fidelity level
- Extracting a clean transparent-background cutout from an existing product photo
