Apply a strict set of modern Python 3.13+ coding standards to maintain a high-quality, predictable, and robust codebase. This skill guides you in writing, reviewing, and refactoring Python by enforcing specific patterns like LBYL (Look Before You Leap) exception handling, modern type syntax (e.g., `list[str]`), safe `pathlib` operations, and absolute imports. It also incorporates production-tested code smell patterns from Dagster Labs to improve API design, parameter complexity, and overall code organization, making it essential for projects that value clarity and maintainability.
