It is marked as critical, opens with \"This session restarted during your previous turn.\", and warns that tool calls from that turn may not have run. A tool call is Claude asking to use a tool, such as running a command.\n\nThe reminder is added only when a remote switch is on, and it is off unless the server turns it on. In readings taken before this release, the server returned off both for this site's account and for an anonymous one.\n\n**Why**\n\nIt stops Claude from wrongly assuming that tool calls interrupted by a restart actually finished.\n\n- Flag `tengu_iterative_lightning`: Off in both readings (read for one account on one subscription tier against v2.1.302; 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: Sessions\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
