What
The interface used for tool-or-agent adapters gained a new method, isTransparentWrapper(), alongside its existing prompt() and mapToolResultToToolResultBlockParam() methods. Right now it always returns false for every adapter.
Why
This lays groundwork for distinguishing adapters that just pass calls straight through from ones that add their own behavior, though no adapter currently reports itself as a transparent wrapper.

The writer flagged doubt
The finding does not say what functionality will read this method or when it might start returning true.
