| description.long | 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. | A platform that identifies unstable tests, automatically isolates them from blocking merges, and provides intelligent merge queue management to reduce build delays and developer friction. |
