Unclear What these two switches control is not known.
What
Two new feature switches, tengu_foamy_whistle and tengu_graceful_fiddle, appear in Claude Code. Feature switches are settings that Anthropic's servers can turn on or off. Nothing yet shows what they control.
A check nearby looks for a model from the 5.x family or later, counting fable and mythos as 5.2.
Why
These look like preparation for features that are not visible yet.
