Unclear It is not known what has to be switched on for this resume to happen.
What
A background agent, sometimes called a subagent, is a helper Claude starts to work on part of a task while the main conversation continues. In a remote session, the machine running the work can restart. Claude Code can now pick back up the background agents that were running, or were cut off, when that happened.
restartResumes sets how many of them can be resumed.
Each one is checked against the session's permission rules first.
An agent the rules now block, or one that needs approval, is not resumed. Claude Code shows a message saying the rules block it or that background agents are off.
Why
Work that background agents were doing in a remote session can carry on after a restart instead of being lost. Permission rules are checked again before anything resumes.
