Questions about Codex prompts for front-end work
Questions and answers
What is the best Codex prompt for building a website?
A self-contained task brief: the goal, the design values in numbers, the files in scope and a definition of done the agent can run. For the design values, our recommendation is to start from a prompt written from a finished design, which is what uberdesigner templates are. That library is ours.
Does this site cover Codex prompts for back-end or general coding?
No. It covers front-end work only: websites, landing pages, components, dashboards, 3D scenes and restyles. The method of brief, scope and checks carries over, but the examples here are all about design.
What is AGENTS.md and do I need one?
It is a Markdown file of instructions in your repository that Codex reads. You don't need one for a single task. For a project with more than a few tasks it is how the design stays consistent. See the example.
Are the prompts on this site free?
Yes. Every example prompt here can be copied without an account. On uberdesigner, free templates' prompts need a free account, and Pro templates need a plan.
Do these prompts work in other coding agents?
Mostly, yes. A brief that describes the result and the checks isn't tied to one tool. The parts specific to Codex are the AGENTS.md file name and the MCP commands in the setup guide.
Why did Codex change files I didn't ask about?
Usually because the brief had no scope. Name the files it may edit and the ones it must not, and add a check on the list of changed files. See follow-up prompts that fix a build.
Is this site connected to OpenAI?
No. It is written by the team that makes uberdesigner, it is not affiliated with or endorsed by OpenAI, and the templates recommended are our own. See about and method.
