The design plugins that make Codex ship real UI

OpenAI Codex writes working code. Left alone it defaults to safe fonts, average spacing, and centered Helvetica. These are the plugins that give it taste: aesthetic skills and design-system rules. Install one, or run all of them inside Open Design.

  • Frontend & UI Override Codex’s default aesthetic decisions before a single line is written.
  • Design Systems Turn your tokens and components into rules Codex follows instead of inventing.
