Register the generic plugin, configure ignores, and enable all generic rules. For oxlint.config.ts or .oxlintrc.json, merge these fields with the existing configuration:
ignorePatterns: [
".agent/**",
".agents/**",
".claude/**",
".codex/**",
".continue/**",
".cursor/**",
".gemini/**",
".opencode/**",
".pi/**",
".roo/**",
".windsurf/**",
"tools/oxlint/anti-slop/**",
],
jsPlugins: [
{ name: "anti-slop", specifier: "./tools/oxlint/anti-slop/index.ts" },
],
Keep every existing ignore. Adjust the final pattern when the plugin was copied elsewhere. Inspect the repository for other project-local agent tooling directories and add them rather than linting installed skills, hooks, or generated agent configuration as application source. Do not broadly ignore all dot-directories, because some repositories keep owned source or checks in them.
For Vite+, add these fields to lint.ignorePatterns and lint.jsPlugins. Also merge the same patterns into fmt.ignorePatterns so vp check does not reformat installed agent assets or the vendored plugin. Merge existing entries instead of replacing them.
Enable these rules at "error", including the native Oxlint companion rule:
{
"oxc/no-accumulating-spread": "error",
"anti-slop/no-array-filter-map": "error",
"anti-slop/no-reduce-accumulator-copy": "error",
"anti-slop/no-chained-type-assertions": "error",
"anti-slop/no-conditional-empty-object-spread": "error",
"anti-slop/no-known-value-widening": "error",
"anti-slop/no-module-mocking": "error",
"anti-slop/no-object-parameters": "error",
"anti-slop/no-reflect-apply": "error",
"anti-slop/no-reflect-get": "error",
"anti-slop/no-runtime-typeof": "error",
"anti-slop/no-shape-in-symbol-names": "error",
"anti-slop/no-unknown-parameters": "error",
"anti-slop/no-unknown-returns": "error",
"anti-slop/no-unknown-type-aliases": "error",
"anti-slop/no-unsafe-dictionary-type": "error",
"anti-slop/no-widen-then-assert": "error",
"anti-slop/require-readable-spacing": "error",
"anti-slop/require-safety-comment-for-type-assertion": "error"
}
For no-array-filter-map, prefer lazy .values().filter(...).map(...).toArray() pipelines only when the target runtime supports iterator helpers; otherwise use an appropriate single flatMap or locally mutating reducer. Review callback order, indexes, sparse arrays, thisArg, and filtering semantics rather than mechanically rewriting chains. Unknown receiver types are deliberately not inferred by this AST/scope rule.
Pair no-reduce-accumulator-copy with native oxc/no-accumulating-spread: the custom rule catches supported non-spread copies such as Object.assign({}, acc, item), Array.from(acc), and array accumulator concat/slice calls. Mutating a fresh local accumulator is allowed; copying individual input items is also allowed. Named callbacks, indirect helpers, and nested accumulator properties are not fully analyzed, so do not claim all quadratic reducers are ruled out.
If the repository declares effect in a package manifest, or the user explicitly requests Effect rules, also register the opt-in Effect plugin:
jsPlugins: [
{
name: "anti-slop-effect",
specifier: "./tools/oxlint/anti-slop/effect/index.ts",
},
],
rules: {
"anti-slop-effect/no-manual-effect-error-tag": "error",
"anti-slop-effect/no-manual-tag-comparison": "error",
"anti-slop-effect/no-manual-tagged-construction": "error",
"anti-slop-effect/no-service-constructor-imports": "error",
"anti-slop-effect/prefer-effect-match": "error",
},
Merge these entries with the generic plugin configuration rather than replacing it. Do not enable the Effect plugin merely because Effect appears transitively in a lockfile; require a direct package-manifest dependency or an explicit user request. The rule covers relative project imports. Report package-alias imports as a current limitation rather than pretending they are enforced.
Complete when the generic rules and eligible Effect rules are registered and existing configuration is preserved.
