What
Auto-compact is when Claude Code automatically shortens a conversation as it nears the model's limit. A window size for this can be supplied with the client's data. That value is now used only when a certain check passes. Otherwise no custom window is set and the default stays in place.
Why
A compaction size supplied this way may now apply only some of the time.
