test.js

module.exports = {
  meta: {
    type: 'problem',
    docs: {
      description: 'Disallow removal of specific CSS classes',
      category: 'Best Practices',
    },
    schema: [], // No options
  },
  create(context) {
    const classesToKeep = ['specific-class-to-keep', /^regex-to-keep-classes$/];

    return {
      Literal(node) {
        if (typeof node.value === 'string') {
          classesToKeep.forEach((cls) => {
            const regex = cls instanceof RegExp ? cls : new RegExp(`\\b${cls}\\b`);
            if (regex.test(node.value)) {
              context.report({
                node,
                message: `The class "${cls}" should not be removed.`,
              });
            }
          });
        }
      },
    };
