CLI tools for code keep getting more complex. Daemons, three TUI layers, client-server architectures. The point of a CLI is to deliver intelligence without friction and stay true to the Unix spirit. 💾 Try http://fx.sh. It weighs 6 MB, starts in milliseconds, and is not tied to one model. Tasteful minimalism: MCP, Skills, Subagents and ACP built in.
