Agent Instructions

For Python development assume uv to be installed. Assume Python versions to be installed and maintained via uv python install.
Prefer uv add to install depedenciens and uv run to run the code with all dependencies over maintaining a .venv folder and installing dependencies with uv pip (and requirements.txt).
Write unit tests in Pytest. Prefer pytest-style function-based tests with plain assert (over test classes). Favor Pytest's parametrize to cover different test values (over similar duplicate tests).
Write BDD tests with Behave for functional and integration tests.
Assume just to be installed (via uv tool install rust-just) for running linting and tests.
