BoraAITA/devtools — reverse-engineered prompt

Build me a small command line dev tools repo with a few simple shell scripts I can use every day. I want one script for quick git actions so I can save all current changes with a commit message, undo the last commit, and create and switch to a new branch with one easy command. I also want a project setup script that can create starter folder structures for a React app, a Node.js API, or a Python project when I pass the type and project name. Add another script that scans a folder and lists files larger than a size I choose in MB.

Please make it easy to clone and use on a Mac or Linux machine, put the scripts in a scripts folder, and include a clear README with example commands and setup steps like making the files executable. Keep it simple and practical, and look up current shell scripting best practices online if you need to.
