Kalmuraee/OpenMagic ? reverse-engineered prompt

Build me a local tool called OpenMagic that adds a floating AI coding toolbar to any web app when I run it from a project folder.

I want to start my normal dev server, then run one command, and have the app open through a proxy with a small toolbar overlaid on top. From the browser I should be able to click any element, describe a change in plain English, preview the suggested diff, and approve it so the real source files get updated and hot reloads the page. It should feel safe, with rollback if a change breaks the build, and it should verify edits before applying them.

Also include a simple visual editor for tweaking text, CSS, and attributes live, plus a quick AI review that checks spacing, hierarchy, contrast, and overall UI consistency. Keep API keys local and support a few major AI providers, with a place to swap models. Make it work across common modern web apps like React, Next, Vue, and plain static sites. If you need to look up current docs online, do that.
