| 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 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. | 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. |
