// Tailwind CSS utility-first CSS framework. Use when styling web applications with utility classes, building responsive designs, or customizing design systems with theme variables.
Use for VBI monorepo development: apps, packages, practices, website documentation, repository-level workflows, generated artifacts, validation commands, source-of-truth decisions, software entropy control, maintainability, refactoring, dead-code deletion, and constraining messy LLM-generated code.
Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or any project with a components.json file. Also triggers for "shadcn init", "create an app with --preset", or "switch to --preset".
Use when writing or reviewing vbi_builder scripts for VBI Chart, Report, or Insight builders inside VBI Agent.
Use when the user asks for analysis that should iterate through multiple hypotheses, experiments, and validation instead of jumping to one answer.
Use when the user's task involves Ant Design (antd) — writing antd components, debugging antd issues, querying antd APIs/props/tokens/demos, migrating between antd versions, or analyzing antd usage in a project. Triggers on antd-related code, imports from 'antd', or explicit antd questions.

Tailwind CSS is a utility-first CSS framework for rapidly building custom user interfaces. Instead of writing custom CSS, you compose designs using utility classes directly in your markup. Tailwind v4 introduces CSS-first configuration with theme variables, making it easier to customize your design system.
