    Parallel Tasks & Code Review

    “While the agent is running, I can check in on other tasks that other agents are working on in isolation. Here you can see all the tasks that I'm currently working on. For example, in this task the agent has completed running. I can see all the changes, edit them, revert them, or comment on them. Once I'm happy, I can create a PR, a draft PR or merge it directly. I can also test the changes by running a lifecycle script.”
