 - **Rerun** errored Tasks from the failing step.

+## By agent view
+
+The Tasks page lets you switch to a "By Agent" grouped view, which organizes the task list by agent instead of chronologically. Use this view when you want to see which agents are handling the most work or to drill into a specific agent's task history.
+
+Each row in this view represents one agent. Click the expand chevron on an agent row to open a nested task sub-table showing that agent's individual tasks. The sub-table displays up to 25 tasks at a time. If there are more tasks matching the current filters or search, a **Show more** button appears at the bottom of the sub-table to load additional tasks.
+
+Click any task row in the sub-table to open the full task detail drawer, where you can review conversation history, tool usage, outputs, and errors.
+
+The sub-table automatically reflects any filters and search terms applied to the parent view — only tasks matching those criteria appear.
+
+**Sub-table states:**
+- **Loading** — A loading indicator appears while the sub-table fetches tasks.
+- **Error** — If the fetch fails, an error message is shown in place of the task list.
+- **Empty** — If the agent has no tasks matching the current filters, the sub-table shows "No tasks to show".
