I Built a Python CLI Toolbox Instead of Writing One-Off Scripts

Whenever I ask an AI assistant to do a small task, it writes a quick Python script for me. Convert an image. Compress a PDF. Convert a CSV to Excel. The script works, I use it once, and then it disappears. At some point I thought: Why keep asking for one-off scripts when I could build my own reusable toolbox? So I did. Toolbox is a small Python CLI with utilities for the file and image tasks I keep needing — CSV ↔ Excel conversion, image grayscale/blur/compress, and PDF compression. Code here: GitHub Repository I had just finished the freeCodeCamp Python certification and wanted to use it for something instead of stopping at the certificate. My background is mainly Node.js, so this also turned into a tour of how Python projects differ from what I already know. From npm to uv The first thing I had to figure out wasn't Python syntax. It was package management. In Node I install with npm install, dependencies live in package.json, and versions lock in package-lock
