This is a submission for the Hacktoberfest Open-Source AI Challenge: Week 4 (Ghost in the Machine).
GhostShell is a terminal wrapper that "possesses" your shell. Every command runs normally, then a ghost whispers one eerie sentence about what you just did. It is about 30 lines of Python, and the UI was designed with Figma Make (prompt in the README).
Run python ghostshell.py, type ls or git status, and read what the spirit says. UI design (Figma Make): https://blush-curl-39070128.figma.site/ . Code: https://github.com/chatgaiyashenanigan-alt/ghostshell
The script runs your command with subprocess, then sends the command and its output to a local Ollama server (llama3.2:1b) with a ghost persona prompt. The reply is printed in purple under the output.
Your shell history holds secrets: paths, hostnames, tokens in error messages. A closed API would send all of that to a server you don't control. With an open-weight model, nothing leaves the machine. It works on a plane with the Wi-Fi off, costs nothing per command, and I can swap the model by changing one string. A hosted model could change or disappear, but this ghost stays as long as the weights are on disk.
I pasted a single prompt (see README) into Figma Make: a marigold-and-violet terminal with fading whisper lines, an offline badge, a model picker, and an "ofrenda" sidebar of past whispers. It gave me a layout I could build from.
