What's Good
The rule coverage is comprehensive: 800+ rules from popular linters. Auto-fix handles most issues. Configuration is straightforward. The formatter (ruff format) now handles code style too.
The Catch
Not every rule from every tool is implemented. Some teams have strong opinions about specific linter behaviors.
Verdict
One fast tool to replace your entire lint toolchain.
