You can now inspect subagent activity for eve projects in Agent Runs.
The new Subagents tab shows every subagent, organized by which turn started it. Each row shows the prompt, duration, and any failures, all on a shared timeline.
Click any subagent to open its run. The tab shows the same details as a parent run: turns, tool calls, metadata, cost, and token usage.
Open Agent Runs to try it, or read the documentation to learn more.
