The OpenAI Launch Nobody's Talking About (ChatGPT Skills)

What's up, everyone? Welcome to the Startup Ideas podcast. Today is December 22. I'm gonna talk about a huge news item, OpenAI quietly launched something not a lot of people are talking about. I'm gonna talk about one trend you could take advantage of, build a business around. I'm gonna talk about one app that I'm using that, you know, I I think you should too. I'm gonna talk about one start up idea and just give it away to you. And at the end, I'm gonna give you a mobile app framework so you can actually go and build a mobile app in 2026, And that's today's episode. So the news item I wanna talk about, that I don't think a lot of people are talking about is, quietly, OpenAI has launched skills. So we've seen anthropic and cloud skills. A lot of people talking about that, including myself, how amazing it is. But quietly, we have codex now officially support skills. Skills are reusable bundles of instructions, scripts, and resources that help codex complete specific tasks. You can call a skill directly with dollarsign. Skill name or let codex choose the right one based on your prompts. So what's really cool is they're just following the agent skills IO standard, the one, by Anthropic. A skill is just a folder, basically an MD, skill dot MD file for instructions and metadata. And all of a sudden your chat GBT and codecs has just become a lot more valuable. So there's a tons tons of ways, that you're gonna be able to use agent skills within codecs or chat g p t. You know, it gives some examples here in the in the official announcement, some technical stuff because it's talking about codecs, specifically, but, like, a notion spec to implementation, skill, a, have codex read and update your linear tickets, skill, have codex automatically fix your GitHub CI failures skill. So it does a lot of things. And, you know, I think a lot of people don't really understand the difference between what is a skill, what is a sub agent, and what is an MCP. So just to, you know, give everyone a little bit of a foundation, a skill is like a written guide that tells, you know, Clode or, you know, codex or ChatGPT exactly how to do a specific task. For example, analyze spreadsheets this way or write emails in this voice or design, you know, design the interface like this. So you can basically call and reuse the same skill again, and it just it allows for more consistent output. So what is a sub agent? Well, a sub agent is making a few extra copies of, you know, the LLM that you're using, you know, CLODE or or codex or ChatGPT, each with its own jobs, such as you review the code, you write tests, you update docs. The main the main LLM can hand out pieces of a big task to …
