 "title": "Run a long desktop task from the browser",
 "page_title": "How to run a long desktop task from the browser with Long Horizon Harness",
 "summary": "Start a multi-step computer task in a web dashboard and keep it running with checkpoints.",
 "who": "A person with a multi-step workflow across desktop apps who wants to start it, watch it, and answer approvals without using the terminal.",
 "problem": "A single agent session often loses track of the goal or stops partway through a long workflow that spans several apps.",
 "outcome": "A task that runs in rounds, with each round planned, executed, verified, and checkpointed, and a final plain-language reply.",
 "steps": [
  "Complete the Installation steps in the README: install the harness and make sure one agent runtime is on PATH.",
  "Run `lh-harness web` to start the Dashboard.",
  "In the browser, start a new task, describe the goal, and choose a backend and model for the Manager, Executor, and Auditor.",
  "Answer any approval requests and send extra instructions mid-run if the task needs changes.",
  "Read the final reply and check the verified state before you rely on the result."
 ],
 "agent_prompt": "Use the LongHorizon-Harness repo at <repo path>. Start the Dashboard with lh-harness web, create a task for <goal>, and let it run until it reports completion. Expected output: the final reply and the verified state for <goal>. Verify that every round the Auditor accepted is listed as a checkpoint before you report success.",
