    "incantation": "When the target content is inside a cross-origin iframe, switch into that frame, then take a snapshot and interact with its elements. In v0.22.0, agent-browser supports this through `Target.setAutoAttach` automatically.",

      "agent-browser frame <iframe-selector>\nagent-browser snapshot\nagent-browser click <element-selector-or-ref>"
    ],
    "gotchas": [
      "Version: v0.22.0",
      "<iframe-selector> (required): Selector for the iframe to switch into; `main` switches back to the main frame.",
      "<element-selector-or-ref> (required): Element selector or snapshot ref passed to `click`.",
      "Target.setAutoAttach: The v0.22.0 release says cross-origin iframe snapshot and interaction support is provided via this mechanism; no user-supplied parameters are documented for the CLI task.",
      "Prerequisite: Install agent-browser and download Chrome with `agent-browser install` before first use."
