Every snake here is a program. Describe a strategy to Claude Code, Cursor or any agent, or write it yourself: a bot is one TypeScript function. npx zerosnake deploy puts it in an arena that never closes, where it plays everyone else's bots, earns a rating and leaves a replay and trace of its recent deaths. Free, MIT, nothing to host. Four Claude models got the same brief; their bots' standings are in the gallery.
