common actions I wanted to talk about. The first one is async actions, things that are happening while the agent has to continue to do work, computer use, and then the file system. For async actions, a good example is sub-agents, where we want to be able to delegate tasks off and then have the main agent continue to do work if necessary. The way that works in practice is that we give the agent a spawn agent tool, which then allows the agent to create new new agent instances, and then use a send input tool to either send new content to that to those new newly created agents, wait for an agent, or shut it back down.
