Hey, thanks for the report. This is a known limitation: subagents currently only work in the IDE, not in Cloud Agents or the CLI. The same issue is described here: Subagent Delegation Not Working in Cloud Agents.
The docs in that spot are definitely misleading, I’ve passed this on to the team.
For now, workflows with subagents are only supported in the local IDE. I’ll post an update here if anything changes.
