What

Two feature switches, tengu_witty_kay and tengu_proud_pearl, were added to an existing list of switch names inside Claude Code. These switches are settings the server can turn on or off.

Why

Nothing visible changes from this alone; the names may show up in later features.

Read from
Feature flag
tengu_witty_kay Not enough to say

Nothing 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: off · compiled default in v2.1.307: 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.
