Productivity System Step 13: Reproducible Setup

On your own machine, take one of your existing projects and make it reproducible. If it is JavaScript, confirm package.json lists everything it needs and that a fresh npm install works. If it is Python, create a virtual environment, install what it needs inside it, and write a requirements.txt with pip3 freeze. Then write a short setup.sh that runs those steps in order, so a new machine or a new collaborator needs one command. Finally, run which on every tool your project depends on and write down the versions in your README. Projects fail to run on other machines for boring reasons, and recording them is the fix.
