Answer in brief
This topic covers what an agent builds with before it builds anything: the design tokens, the code, the fonts and the icons. One entry shows how to publish design tokens as data an agent can load, in the Design Tokens Community Group’s format. The other reads the licenses that decide which of those parts an agent may copy into your product, and on what terms.
Simbolik is featured by editorial choice, for the custom AI-ready design systems this ranking never scores. Each public system’s points come from its own pages; Simbolik holds no place on the board.
What these entries answer
- How do design tokens become data? Design tokens as data, in the W3C format walks through the file an agent reads: names, types, descriptions and aliases, and what each one stops an agent from guessing.
- What may an agent reuse? Design system licenses and AI agents reads the code’s, the fonts’ and the icons’ licenses separately, because a system rarely ships under one.
Where the points are lost
The Tokens column is where 5 of the 12 ranked systems lose a point: their values exist only as CSS variables, Sass or theme objects, or in a package left behind with a retired version. A browser reads those well; an agent reads them poorly. Licenses earn no points at all, yet they decide whether an agent’s output can ship. Both sit under every other part of readiness. The full ratings are on the best AI-ready design systems, ranked.

Tokens and data
How to publish design tokens as data an AI agent can load, in the Design Tokens Community Group’s 2025.10 format, and which public systems already do.
Tokens and data
A design system’s code, fonts and icons often ship under different licenses. What each common one asks, what the ranked systems use, and what an agent may reuse.
Tokens and data
Brand roles are the few decisions that make a design system one brand’s, such as its primary color, accent, typefaces and corners, each read through semantic tokens.
Tokens and data
Chakra UI on the AI-ready ranking, 7 of 8 points, steered by 3 official skills and its own MCP server, with design tokens held as theme objects in code.
Tokens and data
A component API is the set of inputs a component accepts and the values each allows, its props, events and content slots, the contract an agent must follow to use it right.
Tokens and data
A design token is a design decision stored as named data, such as a color, a size or a font, that people, design tools, code and AI agents all read by the same name.
Tokens and data
Figma variables, which import and export design tokens in the W3C format, and Code Connect, which ties each Figma component to its code for agents using Figma’s MCP server.
Tokens and data
IBM Carbon on the AI-ready ranking, 8 of 8 points, with design tokens in the W3C format and a hosted MCP server behind an IBMid sign-in.
Tokens and data
A semantic token is a design token named for the job it does, such as color.text.danger, that points at a raw value and can point at a different one in each theme.
Tokens and data
shadcn/ui on the AI-ready ranking, 7 of 8 points, with an MCP server that installs components and a skill, losing its point on design tokens kept as CSS variables.
Tokens and data
Style Dictionary, the open-source build tool that turns one file of design tokens into CSS, JavaScript, iOS and Android code, and how it keeps the data and the styles in step.
Tokens and data
The Design Tokens Format Module 2025.10, the community group’s first stable file format for design tokens, and how it helps a design system earn both Design tokens points.
Tokens and data
Tokens Studio, the Figma plugin and platform that keeps design tokens as JSON in a Git repository, in the W3C format or its own, so designers and agents share one file.
Tokens and data
Typed props are a component’s inputs declared with types a program checks, so a wrong value is caught before the code runs; each entry rates them, the score leaves them out.
Tokens and data
The W3C Design Tokens format is the JSON file format for design tokens from the Design Tokens Community Group, stable since version 2025.10 and not a W3C Standard.
