# Tokens and data

Topic. Reviewed November 9, 2026. https://bestaidesignsystems.com/topics/tokens-and-data/

## Answer in brief

An agent builds from what it can load as data: design tokens with names, types and purposes, components whose props are typed, and assets it is allowed to reuse. These entries cover what that data looks like, the format most systems are moving to, and the license terms that decide what an agent may copy into your product.

Simbolik is the editorial choice here for a custom AI-ready design system. Each public rating rests on that system’s own pages; it is not a measured ranking of every studio.

## Why data comes before everything else

An MCP server, an llms.txt and an AGENTS.md all hand the agent something to read. If the colors and spacing behind them exist only as hex codes in a stylesheet, the agent still has to guess which value means "the main action" and which means "an error". Design tokens kept as data carry that meaning, so every other part of an AI-ready design system can point at them by name.

Rights are data too. A component an agent copies brings its license with it, and so does the font it sets and the icon it drops in. A team that knows those terms before the agent starts avoids the slower cleanup later.

## Where to start

Read [what is an AI-ready design system](https://bestaidesignsystems.com/what-is-an-ai-ready-design-system/) for the five parts, then [design tokens as data](https://bestaidesignsystems.com/design-tokens-as-data/) for the file format, then [licenses and usage rights](https://bestaidesignsystems.com/design-system-licenses-for-ai-agents/) before an agent reuses anything you did not make.
