 Usage notes:
+- Always include a short description (3-5 words) summarizing what the agent will do
 - Launch multiple agents concurrently whenever possible, to maximize performance; to do that, use a single message with multiple tool uses
 - When the agent is done, it will return a single message back to you. The result returned by the agent is not visible to the user. To show the user the result, you should send a text message back to the user with a concise summary of the result.
 - You can optionally run agents in the background using the run_in_background parameter. When an agent runs in the background, you will need to use ${TASK_TOOL} to retrieve its results once it's done. You can continue to work while background agents run - When you need their results to continue you can use ${TASK_TOOL} in blocking mode to pause and wait for their results.
