disallow-stylelint-allow-empty-input

Disallow configuring Stylelint's top-level allowEmptyInput option inside authored Stylelint config files.

Targeted pattern scope

This rule targets Stylelint config modules such as stylelint.config.ts, stylelint.config.mjs, and .stylelintrc.js.

It focuses on top-level exported config objects, including configs wrapped in defineConfig(...).

What this rule reports

This rule reports Stylelint config objects that include a top-level allowEmptyInput property.

Why this rule exists

allowEmptyInput changes runtime behavior for file discovery and no-op lint runs. That policy is an execution concern and should be controlled at invocation level, not embedded in shared config state.

❌ Incorrect

export default {
    allowEmptyInput: true,
    rules: {},
};

✅ Correct

export default {
    rules: {},
};

Behavior and migration notes

This rule removes the top-level allowEmptyInput property.
It preserves the rest of the config object.
Prefer explicit file globs and task-level invocation behavior for empty-input handling.

ESLint flat config example

import stylelint2 from "eslint-plugin-stylelint-2";

export default [stylelint2.configs.configuration];

When not to use it

Do not use this rule if your team intentionally enforces one shared allowEmptyInput policy in committed Stylelint config files.
