What
A subagent is a separate helper that Claude starts to handle part of a task. Each one has a transcript, meaning its record of the conversation, and a set of details about it. When those transcripts are loaded, entries that hold the subagent's details are now separated out. In some cases the details are rebuilt from those entries and checked before use.
Why
This lets a subagent's details survive being sent to and from the server that stores transcripts.
