One-shotting a Raccoon Heist game using Claude Fable 5
Claude Fable 5 built a complete playable game from a 2022 tweet screenshot in one session
Simon Willison used Claude Fable 5 in Claude Code for web to generate a fully playable 'Raccoon Heist' browser game from a 2022 tweet with minimal intervention, demonstrating strong one-shot code generation capability. He also shares a practical workflow using GitHub Pages to preview Claude Code for web output during long-running sessions. The demo is illustrative of current frontier model coding ability but is a developer experiment rather than a product or research announcement.
