When writing style guidance (including README/CONTRIBUTING snippets), keep examples concise and readable:

1) Use idiomatic tool invocations (avoid redundant arguments)

• Don’t include “current directory” arguments if the tool already defaults to the working directory.
• Prefer the documented, explicit subcommand form when required.

Example:

# Prefer (defaults to current directory)
ruff check

# Only specify a path when you truly need it
ruff check path/to/package

2) Format lists in sentences with consistent punctuation

• Use clear separators and an Oxford comma when listing multiple items (e.g., “filter, and reduce”) to prevent ambiguity.

Example:

List comprehensions and generators are preferred over the use of `lambda`, `map`, `filter`, and `reduce`.
