When should I use tomlkit instead of Python's built-in tomllib?

You should use tomlkit when you need to write or modify TOML files while preserving comments and formatting. Use tomllib only when you need read-only access in Python 3.11+ and want to avoid external dependencies.

Can I use this for XDG-compliant configuration management?

Yes, the skill includes integration patterns for the XDG Base Directory specification to ensure your Python application stores configuration in the standard user directories.

How does the skill handle atomic updates?

It provides a robust pattern that writes changes to a temporary file before moving it to the final destination, preventing configuration corruption if a write process is interrupted.

Does this skill help with pyproject.toml files?

Yes, it provides specific patterns and best practices for reading and writing pyproject.toml files, ensuring that the tool-specific configurations and comments remain intact.
