Описание

Добавлена прикладная система тегов для компонентов в документации и в MCP-данных, чтобы ии ассистентам проще находить компоненты по типу задачи (формы, модалки, навигация и т.д.). В пакете @vkontakte/vkui-mcp появились инструменты для получения списка тегов и фильтрации компонентов по тегу.

На данный момент список тегов такой:

[
  "accessibility",
  "badge",
  "button",
  "card",
  "date-time",
  "form",
  "layout",
  "list",
  "loading",
  "media",
  "modal",
  "navigation",
  "notification",
  "overlay",
  "provider",
  "search",
  "selection",
  "typography"
]
