A new banner for first-time users is gated behind the tengu_birch_lantern feature flag. When shown, it displays:
"New here? Type /powerup for a 5-minute tour — modes, undo, @-mentions, and how to teach Claude your rules."
A "step" arm shows a slightly different message focused on quick lessons. The /powerup command itself remains available to all users.

tengu_birch_lantern Not enough to sayNothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.
This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.181: 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.
Read once, for one account on one subscription tier, against v2.1.181. It isn't a statement about your account. What a flag value here can and cannot tell you
A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
