    "incantation": "When tests read Cypress environment variables, migrate those reads to `cy.env()` and request only the needed keys. After migrating all usages on Cypress 15.10.x, set `allowCypressEnv: false` in the Cypress configuration to prevent further use of `Cypress.env()`.",
    "examples": [
      "cy.env(['<key>']).then(({ <key> }) => {\n  // Use <key> here\n})",
      "const { defineConfig } = require('cypress')\n\nmodule.exports = defineConfig({\n  allowCypressEnv: false,\n})"

      "keys (required): Non-empty array of non-empty environment variable key strings to retrieve. Undefined values are returned for keys not set.",
      "options.log: Boolean; defaults to `true`. Displays the command and requested key names in the Command Log, never values.",
      "options.timeout: Milliseconds to wait for `cy.env()` to resolve; defaults to `4000` and does not follow `defaultCommandTimeout`.",
      "allowCypressEnv: Set to `false` in Cypress configuration to disallow the deprecated `Cypress.env()` API on Cypress ^15.10.0.",
      "Prerequisite: `cy.env()` requires Cypress 15.10.0 or newer, must be chained from `cy`, and requires a non-empty array of non-empty strings.",
      "Prerequisite: `allowCypressEnv` is available on Cypress ^15.10.0; Cypress 16.0 removes both it and `Cypress.env()`."
