What

Claude Code sends usage reports about what happens during a session. Two of them now include which agent the event came from:

  • leaving plan mode, the mode where Claude Code plans before making changes
  • the end of compaction, when Claude Code shortens a long conversation to fit

Information recorded about tasks now carries the same detail. A subagent is a helper run of Claude Code that works on part of a task.

Why

This lets these events be traced to the particular subagent they came from. It is mostly a change to reporting.
