cook is a shell-native AI agent that runs tasks you describe in plain English — right from your terminal. No editor plugins. No subscriptions. No runtime dependencies. Just a single binary that works with the LLM provider you already have (OpenAI, Anthropic, Google, Groq, or Vercel AI Gateway). Download it, set an API key, and you're running in 10 seconds. curl -fsSL https://getcook.dev/install.sh | sh
