Part of it can be worked out ahead of time, a step called precompute. The usage data Claude Code sends about compaction now includes a count of display-only messages, ones meant for showing on screen, that this step left out.\n\n**Why**\n\nThis suggests the precompute step now leaves display-only messages out of what it works from.\n\n- Area: Telemetry\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
