Codex Builds Full Landing Page (Agent Skills Demo)

OpenAI added Agent Skills to Codex, using the same open standard Anthropic released. So I installed the same skills from my last video and ran GPT 5.2 through the same landing page test. The skills I used here were built for Claude Code. They work in Codex without modification – same standard, same repos. Opus 4.5 still wins on polish with fewer bugs, but Codex picked up both skills automatically and generated nine images in under seven minutes. Next up: Gemini when they add skills support. Prompt used: Create a landing page design for a local skydiving company. Use typography and design style that works for this niche. Use icons from Font Awesome instead of using emoji. Create these sections for the site: Header/Nav Hero About Services/Experiences Training Programs Gallery Testimonials Book Your Jump/CTA Contact Us Footer Have clear calls to action, good content for SEO, and contact information visible. Generate at least five images that make sense for this design and include images that showcase their best work.
