SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

codex-vision removes the friction of routing image-related tasks through OpenAI Codex, so you can review an existing screenshot, generate a new visual, or edit an image using a single Claude Code shell skill.

Core Features & Use Cases

  • Codex-side screenshot review (review mode): Analyze an existing PNG/JPG/WebP/GIF and return Codex’s prioritized findings and fixes.
  • Image generation (generate mode): Produce a UI mock or visual artifact from a prompt via Codex image_gen, saving the result to an output path.
  • Image editing (edit mode): Modify an existing image by passing it to Codex with edit instructions, then save the edited output.
  • Session continuation controls: Optionally resume Codex sessions across follow-ups using cached UUIDs or explicit resume flags to keep context warm.

Quick Start

Use codex-vision to review a screenshot by running the review mode with an image path and your critique prompt.
