Use when authoring, creating, or debugging a Betta Grasshopper plugin or component — turning plain attributed C# service methods into Grasshopper components with zero hand-written GH_Component code. Trigger whenever the user works with [GrasshopperMethod]/[GrasshopperParameter]/[GrasshopperCollection]/IBettaCollection, references Betta.Abstractions, asks why a saved .gh broke, or wants a Grasshopper component generated from a C# method. Covers the contract, attribute set, return-type → output mapping, defaults, custom icons, GUID/save-reload stability, and deployment.
