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