taojy123/KeymouseGo ? reverse-engineered prompt

Build me a simple desktop app that can record my mouse clicks and keyboard input, then play the same actions back later with a hotkey or a start button.

I want it to feel like a lightweight macro tool for repetitive work, something I can use to record one task and let the computer repeat it for me. It should let me stop and start recording, save each recording as a script, and run a chosen script as many times as I want, including forever if I set the repeat count to zero. Please make it work on Windows, Linux, and macOS if possible, and keep it easy to run from a normal app window as well as from the command line with a script file.

Use a clean, simple interface, add sensible default hotkeys like start and stop, and make the recorded scripts easy to edit by hand. If you need to check current docs or platform details online, go ahead and do that.
