| 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 a developer or analyst extracting text from several document formats before search or supplying selected passages to an AI agent. It provides a repeatable CLI command and Python library, while requiring review against the original. It is not intended for layout-perfect document publishing. | For developers and small teams that want architecture and data-flow diagrams close to the repository and reviewable as text. Use it when relationships matter more than pixel-perfect placement; not for free-form marketing design or exact manual positioning. |
