What the skill teaches
OpenAI's image skill for Codex, kept in the .system folder of the openai/skills repository, which the README says installs automatically in the latest Codex. By default the agent uses Codex's built-in image_gen tool to create or edit bitmap images such as photos, illustrations, sprites, mockups and transparent cutouts, with no API key. A bundled Python CLI with generate, edit and batch commands is a fallback used only when the user asks for it, and it needs OPENAI_API_KEY. The agent copies images meant for the project into the workspace, avoids overwriting existing files, and prefers SVG or code when that suits the job better.
Capabilities
- Generate or edit bitmap images with Codex's built-in image tool
- Run batch generation through a fallback CLI with an OpenAI key
- Save project images into the workspace under versioned names
