babarshahzad2005/repotour ? reverse-engineered prompt

Build me a Python CLI called Repotour that looks at a git repository and generates a friendly tour for new contributors. I want it to tell people where to start reading, what parts of the codebase matter most, and who they should ask if they get stuck. The tour should be grounded in evidence, so every claim should point back to something real in the repo.

Please set up the project so it feels like a real working tool, with a clear command line entry point, config support for a .repotour.yml file, and a simple path for adding more analysis later. Keep the code clean and easy to extend, since this is meant to help with onboarding and developer documentation. Include tests for the main behavior and make sure the README and docs reflect that the project is still in design if something is not fully implemented yet. If you need to, look up current Python tooling docs online.
