| Best use | Best for an individual Python developer or small team that wants consistent linting, import organization, and formatting locally, in editors, and in CI. It adds reviewable rules, safe-by-default fixes, and a pinnable version. It does not replace tests, type checking, or business-logic review, and migration from Black or Flake8 should be tested on a branch. | Best for an individual developer or small team that wants consistent product names, terminology, and documentation style before merge. It applies the same rules to human- or AI-written prose locally and in CI. It is not a translator, semantic fact checker, or Arabic grammar checker through English packages. | For a Python developer or small team that wants a shared setup rather than relying on manually installed packages. Commit the dependency definition and lockfile, then sync the environment and run commands with uv. It does not isolate the operating system or untrusted code, or replace application compatibility tests. |
