Prompt hook configuration

Set type to "prompt" and provide a prompt string instead of a command. Use the $ARGUMENTS placeholder to inject the hook's JSON input data into your prompt text.

This Stop hook asks the LLM to evaluate whether all tasks are complete before allowing Claude to finish:

{
  "hooks": {
    "Stop": [
      {
        "hooks": [
          {
            "type": "prompt",
            "prompt": "Evaluate if Claude should stop: $ARGUMENTS. Check if all tasks are complete."
          }
        ]
      }
    ]
  }
}
