Pi#8

Mario Zechner's minimalist terminal coding agent — four core tools, instant startup, and TypeScript extensions.

Pi adheres to a philosophy of radical software simplicity. Created by Mario Zechner, Pi equips LLMs with just four essential primitives (read, write, edit, bash) inside a minimalist, keyboard-driven terminal user interface. Additional capabilities, linters, and model routing rules are implemented via lightweight, single-file TypeScript extensions.
