Build me a small Python CLI tool that helps improve an existing project by applying standard config templates and common cleanup changes.

I want it to feel easy to use from the terminal, like I can point it at a Python repo and have it suggest or apply sensible improvements for linting, formatting, and general project polish. It should also have a helpful command line help screen, clear defaults, and be packaged so it can be installed and run with pipx.

Please include a few practical templates or examples for common project setup tweaks, and make sure the code is organized cleanly with tests. If you need to check current best practices for Python packaging or CLI behavior, look them up online and follow the latest docs.
