Plugins are how you can extend ViewLint. While there are pre-built plugins, including ViewLint's own @viewlint/rules, sometimes you want to build your own plugins.

Most plugins provide two things:

• New rules
• Reusable configuration presets (Configs you can extends)

If you want ViewLint to catch something specific to your product or design system, a plugin is usually the right tool.

• Check that UI is following your design system
• Check for interactions specific to your website

If you are trying to solve a one-off problem, you can often start with a custom View or Scope instead. Plugins are best when you want a check you can reuse and share.
