What

A subagent is a helper agent that Claude starts to handle part of a task. When one runs in the foreground, you wait for it to finish. Claude Code records some details each time it starts a subagent this way, such as whether default settings were used and which model was used. Those details now also note that the launch was in the foreground.

Why

This adds a detail to how foreground subagent launches are recorded. Nothing here changes what the subagent does.
