What
When a conversation grows too long, Claude Code shrinks it into a summary, which is called compaction. It can prepare that summary in advance. The check that decides when a prepared summary can be reused was moved into a shared helper. No change in behaviour has been confirmed.
Why
This may affect which prepared summaries Claude Code reuses.
