It is off unless it is switched on remotely, and it also needs the lean prompt setting (a shorter version of Claude's instructions) to be on.\n\n**Why**\n\nIf this is switched on for an account, the instructions Claude receives may change.\n\n- Flag `tengu_temporal_hare`: Not enough to say (read for one account on one subscription tier against v2.1.301; this account: no value returned, anonymous baseline: no value returned, 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: System Prompt\n- Tier: Nothing to try yet\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no\n- Present in the build but not switched on"}
