| 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. | For documentation authors and small teams checking references locally or in CI. Start with a specific file and interpret findings; it does not establish complete site or login functionality. | For developers reviewing features as small changes and revisiting earlier steps. Start with a separate practice clone to learn working copies and Bookmarks; delay team adoption until compatibility with required Git tooling is checked. |
