      "state (required): Use `offline` to simulate offline mode or `online` to restore connectivity.",
      "Prerequisite: The network tools are documented as opt-in via `--caps=network`.",
      "Prerequisite: The README lists Node.js 18 or newer and an MCP client as requirements.",
      "Docs conflict: In the same README, the network tool section says to enable `--caps=network`, but the `--caps` option description lists only `vision`, `pdf`, and `devtools` as possible values."
