Contributions

Make the preferred code patterns explicit

Anti-slop turns his TypeScript and JavaScript preferences into Oxlint rules. Examples reject unsafe assertion chains, broad function contracts and code that discards known type information before asserting it back. Rules use syntax and lexical scope rather than a full TypeScript checker, so the project documents which same-file flows it can recognize and which imported definitions remain outside its analysis.[4]

Maintain a local policy instead of accepting a fixed package

The rules are intended to be copied into a repository and adapted to its standards. The installation skill configures Oxlint and records the upstream version; updates preserve local customizations. This makes the rules an explicit team policy. It does not establish that every rejected pattern is wrong in every program or that the linter proves correctness.[4]

Ideas

In his interview with Kent C. Dodds, Mulroy describes watching users work, learning from support escalations and treating observability as part of product engineering. His background includes internal insurance tools, consulting at Formidable and Vercel’s domains work. The common concern is how a tool changes the task someone must complete, including the repetitive steps that are easy for its builder to overlook.[3]
