Extending VX

VX is built to be extended from a plugin or theme, without editing VX itself. Each article shows a complete, minimal example: dynamic data (tag groups, modifiers and builtins), visibility rules, abilities for AI assistants, and custom validation.

Classes under VxFramework\Modules\… that aren't described here are internal and may change between versions.
