Prompt Creatures turns your Claude Code sessions into a living game. Every prompt you send feeds your digital creature — neglect it and it dies. Install the CLI, hook it into Claude Code, and your egg hatches after 3 prompts. No tokens consumed, free to run. The real fun is multiplayer: jump on the world map, find other trainers, and battle their creatures. Win to level up, expand your base, climb the leaderboard. Local-only mode available too.
