Unclear It is not known what feature this switch controls.

What

A feature in Claude Code that used to follow the switch tengu_woolly_leaf now follows a new switch, tengu_fizzy_wren. Switches like this are settings Anthropic's servers can turn on or off. The new one stays off unless it is turned on remotely.

Why

The feature now depends on a different switch, so whether you get it no longer follows the old one.

tengu_fizzy_wren 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.

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.

tengu_woolly_leaf Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.
