Unclear It is not clear what reads this marker or what it changes when you stop agents.
What
A subagent is a helper that Claude starts to work on part of a task. Subagents that run in the background, and agents started by workflows, now carry a marker, stoppableByKillAgents, saying they can be stopped by the action that stops running agents.
Why
In practice, this may decide whether that stop action applies to these agents.
