AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill provides the necessary commands and style guidelines for maintaining code quality in Megatron-LM. It covers the execution of automated formatting scripts, the management of linting tools, and specific coding standards required for the codebase.
What it does
- Provides instructions for running the automated formatting script.
- Lists the specific linting tools used, including ruff, black, isort, pylint, and mypy.
- Outlines requirements for type hints and docstring formats.
- Defines naming conventions and line length constraints.
- Explains how to set up the linting environment using uv.
When to use it
- Before submitting a pull request to ensure code style consistency.
- When fixing style violations reported by CI.
- After modifying imports in Python files.
- When setting up a local development environment for linting.
Advantages
- Ensures adherence to project-specific coding standards.
- Automates the process of code formatting and linting.
- Provides a centralized reference for style rules and tool usage.
Usage examples
- “How do I run the autoformatter for Megatron-LM?”
- The agent provides the command to run tools/autoformat.sh in either check-only or fix mode.
- “What are the naming conventions for Megatron-LM?”
- The agent explains the use of snake_case for functions and variables and PascalCase for classes.

Linting and Formatting
Running the Formatter
Run before opening a PR:
# 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.shTools 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:
uv run isort <file1>.py <file2>.pySetting Up the Linting Group
Inside the container:
uv sync --locked --only-group lintingThis 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, notOptional[X].Docstrings: Google-style on all public classes and functions.
Naming: follow Python conventions —
snake_casefor functions and variables,PascalCasefor classes.Line length: 119 characters (configured in
pyproject.toml).No bare
except: always catch specific exception types.
