Can someone provide a reproducible example? Like a repo to recreate? Here are some tips for providing a Short, Self Contained, Correct, Example and our own Troubleshooting Cypress guide.

Yes:

module.exports = {
  foo: 1
}

import * as cy from "cypress";
import { foo } from "index";
describe("Going to the Org Summary page", () => {
  it("does something", ()=>{
    cy.wait(foo);
  })
})

{
    "env": {
        "browser": true,
        "es2021": true
    },
    "extends": [
        "plugin:cypress/recommended"
    ],
    "parserOptions": {
        "ecmaVersion": 12,
        "sourceType": "module"
    },
    "plugins": [
        "cypress"
    ],
    "rules": {
    }
}

~/DearestIndigoServer$ npx eslint index.spec.js

Edit: Is lintable.

import * as cy from "cypress";
import {foo} from "index";
const bar = foo;
describe("Going to the Org Summary page", () => {
  it("does something", ()=>{
    cy.wait(bar);
  })
})
