Under the hood
propose_skills and DesignSync tools refactored internally to a per-call factory pattern
What
The propose_skills tool, along with a nearby DesignSync-related tool, now build their input-validation, permission-check, and call logic inside a create(r) method that returns an object, instead of defining those functions directly on the tool's definition.
Why
This is an internal code restructuring with no described effect on behavior; it changes how the tool's implementation is organized rather than what the tool does.
