-The following list summarizes the tasks and features supported by Docs Agent:
+Docs Agent's `agent runtask` command allows you to run pre-defined chains of prompts,
+which are referred to as **tasks**. These tasks simplify complex interactions by defining
+a series of steps that the Docs Agent will execute. The tasks are defined in `.yaml` files
+stored in the [`tasks`][tasks-dir] directory of your Docs Agent project. The tasks are
+designed to be reusable and can be used to automate common workflows, such as generating
+release notes, updating documentation, or analyzing complex information.

+To set up and run the `agent runtask` command, see [Set up Docs Agent CLI][cli-readme].
