ruff

v1.0.0+codex.fbe8111fb96d

ruff — Astral's one fast (Rust) binary that is both a Python linter (`ruff check`) and a Black-compatible formatter (`ruff format`). Use when linting or formatting Python, configuring `[tool.ruff]`/`ruff.toml`, choosing rules with `select`/`extend-select`/`ignore`, looking up codes like F401/E501/B008, applying fixes (`--fix`, `--unsafe-fixes`), suppressing (`# noqa`, `# ruff: ignore[...]`), or enabling preview rules. Includes `(ruff 0.X+)` + preview annotations. Not uv or ty.

ruff — Astral's single, extremely fast (Rust) binary that is BOTH a Python linter (`ruff check`, ~970 rules replacing Flake8, isort, pyupgrade, bandit, pydocstyle, parts of Pylint) and a Black-compatible formatter (`ruff format`). Use when linting or formatting Python, configuring `[tool.ruff]` in `pyproject.toml` or a `ruff.toml`/`.ruff.toml`, choosing rules with `select`/`extend-select`/`ignore`, looking up a rule code like F401/E501/B008/UP006, applying autofixes (`--fix`, `--unsafe-fixes`, `--diff`), suppressing violations (`# noqa`, `# ruff: ignore[...]`, `--add-noqa`), enabling preview rules, adopting ruff in an existing codebase, or wiring it into pre-commit/CI. Triggers on mentions of ruff, `ruff check`, `ruff format`, `ruff.toml`, `[tool.ruff.lint]`, "ruff rule", `# noqa`, or migrating off flake8/black/isort. This is the **ruff linter/formatter by Astral** — NOT uv (packaging) or ty (type checker), separate Astral tools with their own skills, and NOT flake8/black/isort themselves.
