Unclear What this experiment and the new beta entry control is not known.

What

Claude Code now looks up a remote experiment setting named tengu_curried_trinket. An experiment setting is a value the server sends to decide which version of a feature an account gets. The name existed before, and it now appears in two more lists of settings Claude Code checks. If the server sends nothing, it falls back to control, the usual name for the unchanged version.

A new entry was also added to the list of beta features Claude Code can ask the API for. Beta features are API capabilities that are still being tested. This one is requested only when a certain condition holds.

Why

This looks like an experiment being prepared. It changes nothing you can see until it is used.

tengu_curried_trinket 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.
