Claude Code now compacts long idle sessions before the prompt cache expires
- Announcement time
- Review updated
Claude Code now compacts long idle sessions just before the prompt cache expires, about an hour in. When you return, it only reprocesses the summary rather than the whole conversation, so it uses less of your usage. On Pro and Max, resuming a very long conversation also warns you first if it would use a big chunk of your 5-hour limit.
