What
A subagent is a helper that Claude starts to handle part of a task, and its transcript is the record of what it did. When Claude Code loads a subagent transcript from the cloud, the usage data it sends now records two more things:
Successful loads: the size and the number of events.
Loads that hit a limit: which limit was passed, whether size, event count or time.
This changes only what is reported, not how loading works.
Why
It helps the people running the cloud service find out why transcripts fail to load.
