What fx is

fx is a minimal coding agent CLI that still comes with batteries included. It's one native binary written in Zig, so there is no runtime to install, and it runs the same on your laptop, in CI, or inside an agent sandbox. Its output is closer to a Unix shell than an IDE, because the conversation prints into your terminal's scrollback instead of filling the screen.
