The usage data Claude Code reports about compaction now includes more detail on work it does ahead of time to prepare one. There is also a new report for when a classifier used during compaction overflows. A report about prefetching for a cloud MCP connection was removed.\n\n**Why**\n\nThis changes what Claude Code reports, not what compaction does for you.\n\n- Area: Compaction\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
