A solid Python coding companion that enforces modern best practices like type hints, PEP 8 formatting, and proper error handling. Pulls you toward Python 3.10+ idioms like f-strings and pathlib, pushes dataclasses and context managers, and won't let you get away with bare excepts or mutable defaults. Comes with practical templates for common patterns and knows the current tooling ecosystem (Black, ruff, mypy, pytest). The anti-patterns section alone is worth having this loaded when you're writing or reviewing code. It's opinionated in the right ways, the kind of thing that keeps your codebase consistent when you're deep in a feature and tempted to cut corners.
