The call that writes this summary now accepts an extra option. When automatic compaction fails, the failure report Claude Code records now also includes details about the agent that was running.\n\n**Why**\n\nThis is internal rework of how compaction is built. It does not show any change you would notice when using Claude Code.\n\n- Area: Compaction\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
