Prototype a WordPress plugin

A prototype is throwaway code that answers a question. This one answers:

Does this specified plugin hold together as a product?

Not "does this logic feel right?" and not "what should this look like?" Those are different prototypes. A state machine with no WordPress surface wants a throwaway terminal app that re-renders the whole state after every keystroke. Visual variations on one component want several structurally different renderings of one route, switched from a floating bar. If the question is really one of those, say so and build that instead — this skill is the wrong shape for it.

This skill applies when there is a WordPress plugin, an admin or front-end surface, and an intent to evaluate behaviour before implementing it.
