 "who": "A Kotlin Multiplatform developer who needs one fact from a third-party page shown inside their app.",
 "problem": "Reading a page inside a WebView usually means one-off evaluateJavascript calls that race each other and the UI.",

 "steps": [
  "Add vitre-core to commonMain dependencies from Maven Central as dev.ggoggam.vitre:vitre-core:0.2.0.",
  "Declare a workflow with navigate, then waitFor on the element that means the page is ready.",
  "Add extract steps for the text you need, and use Source.Attribute(\"href\") for link targets.",
  "Mount a WebView, take its controller, and call WorkflowEngine(controller).run(workflow).collect.",
  "Read event.variables in the WorkflowEvent.Completed branch."
 ],
 "agent_prompt": "In the Kotlin project at <project-path>, add dev.ggoggam.vitre:vitre-core:0.2.0 from Maven Central and write a workflow that navigates to <target-url>, waits for <ready-selector>, and extracts <field-selector> into a variable. Expected output: the extracted value printed from WorkflowEvent.Completed. Verify that the Completed event contains a non-empty value for that variable.",
