Unclear It is not known what this gate controls or what Claude Code does when the server sends no value for it.
What
Claude Code now contains the name of a new feature gate, tengu_binary_lollipop. A feature gate is a switch that Anthropic's servers can turn on or off for an account without a new release. Nothing in Claude Code is known to use it yet, so there is no behaviour to describe.
Why
A new gate name usually marks a feature still being built. For now it has no visible effect on how Claude Code works.
