What
Compaction is when Claude Code summarises the older part of a long conversation to free up room. It now:
- keeps critical system reminders through compaction and passes them on to helper agents
- shortens or saves to a file any very long report handed back by another agent
Before, only the queued commands from those handed-back reports were carried over.
Why
Long sessions with several agents lose less important information when the conversation is compacted.
