I've been building TerminallySKILL, a free desktop app that tries to solve a problem I kept running into: having a dozen terminal windows open, a separate SSH client, a browser tab with man pages, and a text file of command snippets I always forget the flags for. It combines a full terminal (xterm.js + node-pty), a visual command builder, reusable snippets, SSH connections, and encrypted VNC remote desktop through SSH tunnels -- all in one workspace.

The visual command builder is the part I'm most interested in getting feedback on. It auto-discovers CLI tools from your PATH, parses their --help output, and presents flags and arguments as form fields. You fill in the form, it builds the command string, and you can review it before running. It ships with 37 built-in definitions for common tools but can detect and build forms for anything on your system. Snippets support {{placeholder}} syntax so you can template out commands you run repeatedly.
