Linting and formatting for Megatron-LM. Covers running autoformat.sh, tools (ruff, black, isort, pylint, mypy), and code style rules.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Linting and Formatting --- ## Running the Formatter Run before opening a PR: ```bash # Check mode (no changes applied) BASE_REF=main CHECK_ONLY=true SKIP_DOCS=false bash tools/autoformat.sh # Fix mode BASE_REF=main CHECK_ONLY=false bash tools/autoformat.sh ``` Tools invoked: `black`, `isort`, `pylint`, `ruff`, `mypy`. --- ## Import Ordering After editing imports in any Python files, always run `uv run isort` on those files before committing: ```bash uv run isort <file1>.py <file2>.py ``` --- ## Setting Up the Linting Group Inside the container: ```bash uv sync --locked --only-group linting ``` This installs `ruff`, `black`, `isort`, `pylint` — the same tools used by `tools/autoformat.sh` and CI's `linting` job. --- ## Code Style Rules - **Type hints**: required on all public API functions. Use `X | None`, not `Optional[X]`. - **Docstrings**: Google-style on all public classes and functions. - **Naming**: follow Python conventions — `snake_case` for functions and variables, `PascalCase` for classes. - **Line length**: 119 characters (configured in `pyproject.toml`). - **No bare `except`**: always catch specific exception types.

How to install
mdr add nvidia/skills/mcore-linting-and-formatting@sha256:8cf1cb7df99031f6The line at the top of this page pins the label git:20260529.416539c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
