Six of these switches are now among the ones Claude Code checks early in startup: `tengu_steady_bittern`, `tengu_valiant_lantern`, `tengu_tender_mitten`, `tengu_zippy_harbor`, `tengu_fallow_lantern` and `tengu_mellow_hollerith`.\n\nFive of them are off unless switched on remotely: `tengu_mellow_hollerith`, `tengu_valiant_lantern`, `tengu_zippy_harbor`, `tengu_tender_mitten` and `tengu_fallow_lantern`. `tengu_mellow_hollerith` decides an answer tied to your login and host. `tengu_steady_bittern` feeds a state that can be answered, unanswered or not yet asked.\n\nFor `tengu_mellow_hollerith`, the server returned off for this site's account and for an anonymous check, in a reading not taken under this release.\n\n**Why**\n\nThese features ship hidden and stay off unless they are switched on from the server.\n\n- Flag `tengu_mellow_hollerith`: Not enough to say (read for one account on one subscription tier against v2.1.300; this account: no value returned, anonymous baseline: off, compiled default: not a boolean we can read) 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: Internals\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
