Alongside periods when work is running, it records when Claude Code is waiting for you to respond, and logs a start and an end for each such wait.\n\nThe events marking the end of a run are only sent when an internal flag is on. That flag is off unless it is switched on remotely, and it read off both for this site's account and for an anonymous account.\n\nSeparately, Claude Code now logs an event whenever it starts or stops advertising a tool host over its bridge connection.\n\n**Why**\n\nThis is observation only and changes nothing you see. It lets Anthropic see how much idle time is spent waiting on the user, which bears on how long the prompt cache (stored context that makes follow-up requests faster and cheaper) is worth keeping alive.\n\n- Flag `tengu_dapper_dawn`: Off in both readings (read for one account on one subscription tier against v2.1.283; this account: off, anonymous baseline: off, compiled default: off) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Compaction\n- Tier: Nothing to try yet\n- Useful: 1\/5\n- Signal: 3\/5\n- Present in the build but not switched on"}
