Can this skill help with pyproject.toml modifications?

Yes, it provides specific implementation patterns for programmatically updating pyproject.toml files while ensuring that the file's original structure and human-readable documentation remain intact.

How do I prevent configuration file corruption during writes?

The skill includes patterns for atomic updates, which involve writing changes to a temporary file and then performing a move operation, ensuring the configuration is never left in a half-written or corrupted state.

Does this skill support Linux configuration standards?

Yes, it integrates with the XDG Base Directory specification to ensure your Python application stores configuration files in the correct, standardized system locations (such as ~/.config/).

Why use tomlkit instead of the standard tomllib?

While tomllib (introduced in Python 3.11) is excellent for high-performance reading, tomlkit is the preferred choice when you need to write TOML files or preserve existing comments, whitespace, and formatting.
