Unclear What each of these six switches controls is not stated.
Some Claude Code features are switched on or off from Anthropic's servers instead of by an update. 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.
Five 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.
For 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.
These features ship hidden and stay off unless they are switched on from the server.
