    OpenAI Releases ChatGPT AI Agent Skills

    Today I break down a big news item I think is flying under the radar: OpenAI quietly launched Skills for Codex, and I explain what that means (and how it differs from sub-agents and MCPs). I then share a fast-moving trend I’m watching and why it’s a strong wedge for a simple app. After that, I recommend the to-do app I’ve used for 14 years and give away a startup idea. I close with a practical 6-step framework for going from idea → viral validation → mobile app launch in 2026.

    Timestamps
    00:00 – Intro: the new format (news, trend, app, startup idea, framework)
    00:40 – AI New Item: OpenAI launches Skills for Codex
    05:45 – Trend: Face Yoga
    07:56 – App Recommendation: Things
    09:33 – Startup Idea: Call-an-expert service for non-developers stuck at 80% done
    14:44 – Framework: Viral Mobile App Framework

    Key Points

    * OpenAI “Skills” make Codex/ChatGPT more reusable and consistent by packaging repeatable workflows.
    * A “skill” is the recipe, a “sub-agent” is extra worker instances, and an “MCP” is the tool access plug.
    * Face yoga is an emerging sub-niche with clear app potential (simple routines, monetization via paid or ads).
    * Last 20 is a practical marketplace idea: pay for 15 minutes of expert unblock help to finish the last 20%.
    * Viral validation favors apps that are visually obvious, explainable in three words, and tied to insecurity-driven outcomes.

    Numbered Section Summaries

    * OpenAI Skills: The Quiet Upgrade I walk through OpenAI’s launch of Skills for Codex—reusable bundles of instructions/scripts/resources that can be called directly or chosen automatically. I’m excited because this makes agent workflows more consistent and scalable across tasks.

    * The Foundation: Skill vs Sub-Agent vs MCP I clarify the taxonomy: a skill is the written playbook, sub-agents are extra “worker” copies of the model that split a big job, and MCPs are what let the model access external systems like tickets or repos. This is the mental model I want everyone using going into 2026.

    * The Trend: Face Yoga As An App Wedge I share a niche trend I’m seeing—face yoga—and why it’s a product opportunity similar to how yoga apps became huge. I call out the obvious app angles: guided routines, jawline/face-slimming programs, and content-driven growth via short videos.

    * The Tool: Things (My Simple Focus System) I recommend the Things to-do app because it’s simple: “Today,” “Upcoming,” and “Someday,” without a monthly fee. I also note what’s missing (I’d like more AI features), but it still wins for focus if you don’t want a “kitchen sink” system.

    * The Startup Idea: Last 20 (Phone-A-Friend For Vibe Coders) I give away the idea: builders get stuck at 80% after using Cursor/Replit/V0, so Last 20 matches them with someone who’s solved that exact wall before. The product is a fast screen-share session—problem solved—priced per session or bundled for teams/agencies, with the marketplace taking a cut.

    * The Distribution Framework: Viral Validation → Launch I share a 6-step process: warm up the account, design a visually obvious app, build a tiny MVP fast, post daily until something hits, build the community before the product, then launch with a hard paywall and keep content rolling. It’s a simple playbook for getting to organic traction in 2026.
