Build Apps in Minutes 🤯 No Coding Required | Codex Skills Explained
summary
Demonstrates building a full Next.js single page app called Agent Card Builder using Codex superpowers installed from a GitHub repo via a skill installer, with prompts run on ChatGPT 5 3.5.4 mini at high intelligence. The pipeline brainstorms, writes an implementation plan, generates code, adds tests and package.json, and successfully runs npm build and npm start. Shows concrete prompts, uses an LLM cost optimizer to save roughly 50 tokens, warns about Codex instability on Windows, and adds test cases to reduce hallucination.
