ai-deslop

What is ai-deslop?

ai-deslop is an npm package that provides opinionated rules for oxlint. It targets code patterns commonly found in low-evidence or AI-generated output. The package combines existing anti-slop rules with custom rules under the deslop/ namespace. It ships as compiled JavaScript and works with any oxlint plugin runtime, including Bun, Deno, and Node.js.

The recommended configuration enables rules focused on type safety and evidence. These rules block nested type assertions, reject unknown parameters and returns, and require safety comments for non-const assertions. They also prevent widening known values into unsafe types.

Additional rule groups address code quality and testing. The tool flags adjacent eager array filters and maps, rejects unnecessary reflect calls, and identifies weak test assertions like substring checks or repeated expect calls. Opt-in rules handle duplicate constants, renamed imports, and canonical Tailwind CSS v4 class spellings.
