Qlty Check

A wrapper around the qlty CLI that unifies linting, formatting, and code metrics across 70+ linters and 40+ languages. You'd reach for this when you want consistent quality checks without juggling language-specific tools. The standout feature is the metrics and code smell detection, which goes beyond what most formatters offer. It requires qlty installed and a config file in your repo, so there's some setup involved. The --fix flag is the real time-saver, auto-fixing what it can so you're not manually tweaking style issues. If you're already using language-specific linters you like, this might be overkill, but for polyglot projects it consolidates a lot of tooling.
