A chess game where users can play against an AI agent named Jev.

Pattern✦ Play chess against Jev

I built a chess game where you can play against Jev. See if you can crush this System One agent—I know I can 😂 Jev still has some learning to do. Open source: github.com/CPPAlien/playwithjev Try it: playwithjev.vercel.app @typesafeai x.com/Creaspan/status/2101907353830662145/

Original post Code

Quality38

NoveltyiHow surprising the Jev use is versus an obvious typed-decision call. Generic mentions score low; a new primitive scores high.47
UsefuliHow reusable the technique is for another builder. Toys score low; a production-quality idea scores high.26
SubstanceiHow much concrete evidence supports the claim: code, numbers, demo, architecture. Hype scores low.43

Quality is Jev’s judgment of the idea. Likes, reposts and views do not affect it. Relevance is a separate gate.
