What real task does your product handle with GPT-6 Astra?
Maker
I used GPT-6 Astra in Codex to build HypeStreet, a fantasy stock market using virtual HypeBucks. Astra helped implement persistent player accounts, a shared market, buy/sell confirmations, portfolios, and the leaderboard. It also helped write tests for duplicate trade requests and concurrent spending, iterate on the homepage through browser checks, and prepare the US Politics catalogue with sourced biographies and credited portraits. I reviewed the results and directed follow-up changes. Astra's documented role is software development in Codex; this entry does not claim an Astra API integration inside the game.

Hey Product Hunt! I'm Enrique, the maker of HypeStreet.
I wanted a game that could largely manage itself without constant upkeep. HypeStreet turns familiar names into a shared fantasy stock market. If you follow AI or have favorite characters and public figures, it gives you a way to build a collection around them and see how it changes as people trade.
You start with 10,000 HypeBucks. Choose an asset, review the cost, and buy shares. Buying moves the price up; selling moves it down. Your portfolio tracks your holdings, and the leaderboard lets you compare your wealth. HypeBucks are play money, with no cash-out or real-world ownership.

I also used it to refine the homepage through browser checks and add the US Politics catalogue with sourced biographies and credited portraits. Those were iterative tasks: I reviewed the results and asked for changes along the way.
I'm entering HypeStreet in the GPT-6 Astra Challenge. I'd love feedback on the game itself: was your first trade easy to understand, what would make you return, and what would you want to trade next?
