Unclear The finding does not say whether callers can still request foreground execution through any other path, or what user-visible effect this has.
What
When Claude Code builds the request to launch a subagent through the Task/Agent tool, it now always marks the run as run_in_background: true, no matter what the caller actually asked for. Previously this reflected the caller's own choice.
Why
This means subagent tasks will now consistently run in the background rather than blocking on the caller's requested setting, which changes how and when their results are surfaced back.
