Vibe Coded an App With Opus 5 to Get Better at The Finals, and It's Working

A longtime “The Finals” player says they’re speeding up practice using Anthropic’s Opus 5, building a training app called FISH (Finals Interactive Study Helper). The tool generates simulated game states—down to gadgets, team compositions, respawn timers and costs, scoreboards, weapons, and objective layouts—then offers two kinds of guidance: “rulebook” answers grounded in the game’s mechanics and “pro strategy” answers intended to be more specific. FISH also drills memorization by quizzing users with images of gadgets, specializations, and map variants without labels until answers are revealed. The app is designed not to interact with game files or run alongside the game.
