How does the skill handle atomic updates?

It provides a proven pattern using temporary files and shutil.move to ensure that configuration files are never left in a corrupted state if a write operation is interrupted.

Why should I use tomlkit instead of the Python standard library?

While Python 3.11's tomllib is excellent for read-only access, tomlkit is the preferred choice for modification because it is the only library that preserves comments, indentation, and formatting during write cycles.

Does it support the latest Python features?

Yes, it covers both the modern tomllib introduced in Python 3.11 and the tomlkit library which supports Python 3.8+.

Can this skill help me manage pyproject.toml files?

Yes, it includes specific implementation patterns for reading and editing pyproject.toml, making it ideal for automating package metadata or tool configuration updates.

開発者ツール

Manages Python TOML configuration files with precision using tomlkit and tomllib while preserving comments and formatting.

概要

The Python TOML Integration skill empowers Claude to handle complex TOML configuration tasks, ranging from simple reading with Python 3.11's native tomllib to sophisticated read-modify-write operations using tomlkit. It specializes in preserving user comments, whitespace, and formatting in critical files like pyproject.toml, ensuring that automated updates maintain human-readable structures. This skill provides expert guidance on implementing atomic updates, validating configuration schemas, and adhering to XDG Base Directory standards for professional Python application development.
