Runs through your Python files checking PEP8 style, type hints, async/await patterns, error handling, and the usual footguns like mutable defaults. It's got reference docs for each category and a five-gate workflow that forces you to document scope, screen for false positives, cite file and line numbers, and run a verification protocol before shipping findings. The opinionated part is good: it knows not to flag things like cast() after runtime checks or Any types when dealing with untyped libraries. If you want structured reviews instead of ad-hoc comments, this keeps you honest about what you actually checked and why you're flagging it.
