kololu777/gh-skill-tui ? reverse-engineered prompt

Build me a terminal app for managing GitHub agent skills across multiple coding agents at once.

I want it to sit on top of gh skill and make it easy to see which skills are installed, which ones are out of date, which ones were edited locally, and which ones came from somewhere else. It should let me pick a source repo, choose one or more skills and one or more agents, then install, update, delete, or propose a PR back to the source from a simple TUI. Make the workflow feel visual and fast, with a tree view, a skills list, an agents list, an installed summary, and a preview screen before anything runs.

It should support both project scope and user scope, read config from a toml file, and use gh underneath for the actual GitHub operations. If you need to check current docs online while wiring it up, do that.
