What
A subagent is a separate helper agent that Claude Code starts to work on part of a task. It can run in the background while you keep working. Claude Code shows a progress row for each subagent.
For a background subagent that has finished, that row no longer shows the task description. It also no longer falls back to the text "Running in the background" when there is no description.
Why
This is a small display change. Finished background agents show less text in their progress rows.
