M9A uses a series of formatting tools to ensure that the code and resource files in the repository are clean and consistent, making them easier to maintain and read.

CI checks code formatting automatically, and you can also run it manually locally.

Formatting Tools

File Type	Formatting Tool
JSON / YAML / Markdown	prettier
Python	ruff

Install Dependencies

pnpm install          # Install Node.js dependencies (prettier, etc.)

ruff is included in the project's Python dev dependencies and will be available after running uv sync.

Manual Formatting

Run the following commands in the project root directory:

pnpm format          # prettier format all files
pnpm format:py       # ruff format Python code

Or run ruff directly:

ruff check --fix .  # Lint and auto-fix Python issues
ruff format .       # Format Python code
