| description.long | A framework that automates the execution of code quality checks as git pre-commit hooks, eliminating the need for developers to manually install language-specific dependencies on their machines to run linters and formatters written in any programming language. | A fast Python linter built in Rust that consolidates multiple linting tools into a single interface. It supports over 500 rules, provides automated fixes for common issues, and runs significantly faster than traditional Python linters on even very large codebases. |
