UI looking flat in Codex? Install the Product Design plugin before you keep prompting for prettier layouts

#What changed

If Codex keeps shipping bland UI, the missing piece may not be another AGENTS.md paragraph—it may be the Product Design plugin. @meghrajai’s tip: for better UI results with OpenAI models in Codex, use Product Design rather than treating every layout ask as a generic coding task (https://x.com/meghrajai/status/2109817133131850069).

OpenAI ships Product Design as an official role-specific plugin for exploring directions, auditing flows, prototyping from a live URL, and turning screenshots into interactive reviews, with handoff toward tools like Figma and Canva (https://openai.com/index/codex-for-every-role-tool-workflow/). Install from the Codex/ChatGPT Plugins directory, or in Codex CLI open /plugins and install Product Design, then start a new session so its skills load (https://developers.openai.com/codex/plugins). Plugins aren’t available in the IDE extension—use ChatGPT desktop Codex/Work or Codex CLI.

#Who is affected

Codex users doing UI or prototyping work in ChatGPT desktop Codex/Work or Codex CLI. Not available in the IDE extension.

#What to do now

Install Product Design from the Plugins directory or via Codex CLI /plugins, start a new session so its skills load, and ask for Product Design explicitly (or @ the plugin) when the goal is design exploration or prototyping—not ordinary implementation.

#What is not confirmed

How much the plugin improves any given UI ask is a community field tip; the plugin’s existence, install path, and IDE exclusion are documented by OpenAI.
