Built a coding agent for my repo in under a minute. No prompt engineering. No made-up skill names. Just answered 4 questions and exported to Claude Code.

Underrated...well I wouldn't say that because I'm just starting, but overlooked maybe. The impact on humanity will be noticed across the globe. Stop reacting. Start reFraming.

A couple weeks ago we were on vacation with friends, and after the kids were asleep we played games -- mostly Qwirkle, which I had never played and am terrible at. I don't care about being terrible at games, so I made a web version to keep playing after vacation: build lines of tiles that share a color or a shape, 2-4 players (or add bots). I wanted it to be low friction, so there are no accounts. Your identity is an anonymous id in localStorage, and you can move it to another device by scanning a QR code or hitting a unique url. Start a game and text someone the link (game slugs are semi-memorable three word phrases), or "Play the computer" and you can play immediately against bots. Games are async-friendly with web push for turn notifications. The stack is one Node process on a small VM, Next.js + Socket.IO, no database. The server and the client use the same engine so moves validate optimistically, and the bots go through the same functions, so bot moves are always legal. State is

Most AI learning tools explain concepts for you through summaries, notes, quizzes, and flashcards. But recognising an answer is not the same as understanding it. That’s why I built ReExplain ( for the @OpenAI Build Week Hackathon. ReExplain flips the roles - the AI becomes the curious learner, and you become the teacher. You explain the material in your own words, while the AI listens, identifies gaps, and asks follow-up questions that challenge you to think deeper. Powered by GPT-5.6 Luna and built with Codex, ReExplain is now live on Product Hunt! If the idea resonates with you, I’d really appreciate your upvote and support 😄 🔗 Product Hunt Launch Link: Watch the demo, try it, and share your feedback! #ProductHunt #OpenAI #BuildWeek #AI #EdTech #Hackathon
