We use uv in this project:
- Never use "uv pip". It's a legacyc throwback for projects not able to transition to uv yet.
- You can always run "uv subcommand --help", (examples: uv run --help, uv sync --help etc.)

Use your sequential thinking tool if you cannot fix an issue in three attempts.
Use gitpython for all git operations. Here is the API reference: https://gitpython.readthedocs.io/en/stable/reference.html
Use idiomatic Typer for CLI operations.
Use pytest for testing and be sure to use it idiomatically and completely.
Use the installed linters and formatters with the --fix or --write flag to automatically fix and format code before attempting to fix stuff yourself.
Aim for maximum maintainability.
Don't repeat yourself.
All our tests should adhere to the FIRST principle:
- Fast
- Isolated
- Repeatable
- Self-validating
- Timely
