I built a ratchet system for ESLint originally that we’ve extended it to work with TypeScript, Terraform, and Biome linters.

integrating with each linger is complex but it pays dividends - it’s so handy to be able to write a new lint rule or introduce an off-the-shelf rule without needing to fix all existing violations.

We maintain allowed error counts on a file-by-file basis which makes it easier for developers to understand where they added the new violation.
