Deslop

Deslop is a linter plugin providing Oxlint rules that reject low-evidence TypeScript code patterns.

Deslop is a collection of opinionated Oxlint rules designed to reject low-evidence, low-signal code patterns typically generated by AI tools in TypeScript projects. It targets type safety issues, code quality anti-patterns, test limitations, and duplicates, with rules renamed under the deslop namespace. The tool ships compiled JavaScript and works with any oxlint JS-plugin runtime including Bun, Deno, and Node.js. It includes specific checks for type assertions, object parameters, runtime typeof, array filter and map passes, test assertions, and Tailwind CSS class spellings. The project is distributed under the MIT license with vendored rules from dmmulroy/anti-slop.
