Yup so for this situation we actually utilize design.md files which we feed to the agents.

You have 3 options to create the design.md file:

1. Get a template based on a site. Library: getdesign.md
2. Generate a design.md file based of any website. context.dev/free-tools/design-md-generator
3. Create your own design.md file.

Pretty sure there are more ways but you get the idea.
