ai-deslop Releases Oxlint Rules to Block Low-Evidence and Unsafe Type Patterns in AI-Generated TypeScript

68AI Score

Executive Summary

Developer releases ai-deslop, an Oxlint plugin suite designed to detect and reject low-evidence 'AI slop' patterns in generated TypeScript. By flagging issues like chained type assertions and conditional empty object spreads, it enforces code quality standards for AI-assisted programming. The tool supports Bun, Deno, and Node.js, aiming to mitigate common hallucinations and inefficiencies inherent in LLM-generated code.

ai-deslop

Opinionated Oxlint rules that reject low-evidence, low-signal, AI-slop code patterns.

Rules are vendored from dmmulroy/anti-slop (generic rules) alongside additional deslop rules, all renamed under the deslop/* namespace. The vendored source is MIT licensed; see Credits below.

Install

BASH

npm install --save-dev ai-deslop
# @oxlint/plugins comes along as a runtime dependency — keep it in sync with your oxlint version

Ships compiled JavaScript — works with any oxlint JS-plugin runtime (Bun, Deno, or Node.js).

Usage

import { defineConfig } from "oxlint";
import { configs as deslopConfigs } from "ai-deslop";

export default defineConfig({
  jsPlugins: ["ai-deslop"],
  options: deslopConfigs.recommended.options,
  rules: deslopConfigs.recommended.rules
});

Rules

Type safety and evidence

Rule	Status	Description
`no-chained-type-assertions`	Recommended	Rejects nested `as` / angle-bracket assertions that fabricate evidence.
`no-conditional-empty-object-spread`	Recommended	Reports object spreads using a conditional `{}` branch to omit fields.
`no-known-value-widening`	Recommended	Rejects known expressions flowing into explicit `unknown`, `object`, or open dictionaries.
`no-object-parameters`	Recommended	Rejects `object` on function inputs.
`no-runtime-typeof`	Recommended	Requires boundary parsing instead of ad hoc `typeof` narrowing.
`no-unknown-parameters`	Recommended	Rejects `unknown` on function inputs.
`no-unknown-returns`	Recommended	Rejects return contracts resolving to `unknown`.
`no-unknown-type-aliases`	Recommended	Rejects aliases whose resolved type is `unknown`.
`no-unsafe-dictionary-type`	Recommended	Rejects dictionary values based on unsafe escape hatches.
`no-widen-then-assert`	Recommended	Rejects widening known evidence before narrowing assertions.
`require-safety-comment-for-type-assertion`	Recommended	Requires an invariant justification for non-const assertions.
`no-pass-through-type-alias`	Recommended	Disallows aliases that only rename another type.

Code quality and APIs

Rule	Status	Description
`no-array-filter-map`	Recommended	Rejects adjacent eager array filter/map passes; allows lazy iterator pipelines.
`no-reduce-accumulator-copy`	Recommended	Rejects non-spread accumulator copies inside reducers. Enable native `oxc/no-accumulating-spread` alongside it.
`no-reflect-apply`	Recommended	Rejects global `Reflect.apply`.
`no-reflect-get`	Recommended	Rejects global `Reflect.get`.
`no-shape-in-symbol-names`	Recommended	Rejects `shape` in locally owned symbol names.

Tests

Rule	Status	Description
`no-call-only-assertions`	Recommended	Flags tests whose assertions only check mock calls.
`no-module-mocking`	Recommended	Rejects Vitest and Jest module mocks.
`no-poor-substring-tests`	Recommended	Rejects testing that a constant string contains substrings.
`no-repeated-expect-call`	Recommended	Flags adjacent assertions that repeat the same call in test files. Reuse the result instead. No fixer.

Opt-in rules

Rule	Status	Description
`no-duplicate-consts`	Opt-in	Reports all-caps constants with the same static value in different files.
`no-duplicate-types`	Opt-in	Reports exact duplicate object contracts. No fixer.
`no-renamed-imports`	Opt-in	Fixes unnecessary named-import aliases when the original name has no module-level conflict.
`canonical-class-names`	Opt-in	Fixes non-canonical Tailwind CSS v4 class spellings.

Standard rules enabled by the recommended config

Standard rule	Status	Description
`typescript/no-deprecated`	Recommended	Disallows using code marked `@deprecated`. Requires type-aware linting.
`typescript/no-require-imports`	Recommended	Disallows CommonJS `require()` imports.
`typescript/no-floating-promises`	Recommended	Disallows floating promises. Requires type-aware linting.
`typescript/no-unnecessary-condition`	Recommended	Disallows always truthy/falsy/nullish conditions. Requires type-aware linting.
`no-unreachable`	Recommended	Disallows unreachable code.
