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

  • Working with imagegen functionality
  • Implementing imagegen features
  • Debugging imagegen related issues
