Unclear What this switch controls is not known.

What

Claude Code contains a new switch, tengu_sprightly_pebble, that the server turns on or off. If the server sends nothing, it is off. It also depends on a second internal check. An earlier reading found it off both for this site's account and for an anonymous one.

Why

This looks like a feature that is built but not yet in use.

Read from
Feature flag
tengu_sprightly_pebble 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.

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.
