Development
Tooling
The project uses:
- Ruff for linting and formatting.
- BasedPyright for type checking.
- Pytest for testing.
Language
Resources, tools and prompts related stuff must be written in Portuguese, because this project aims
to be used by non-dev folks, such as lawyers and law students.
Technical legal vocabulary is highly dependent on a country's legal tradition and translating it is
no trivial task.
Development related stuff should stick to English as conventional, such as source code.
