Adobe Spectrum 2

Four of these are the comparison’s columns and typed props is the fifth; each was opened on November 8, 2026, and each holds for React Spectrum S2.

• Design tokens: Yes. @adobe/spectrum-tokens (opens in a new tab), version 15.6.0, is a published JSON package with its own JSON schemas, and it carries an llms.txt and an AGENTS.md of its own.
• Agent access: Yes. The official React Spectrum MCP server, @react-spectrum/mcp, is set out on the Working with AI page (opens in a new tab), with install steps for 5 coding tools.
• Docs agents can read: Yes. React Spectrum has an llms.txt (opens in a new tab), and every docs page opens as Markdown when you add .md. It has no llms-full.txt.
• Guidance for agents: Yes. The same page (opens in a new tab) explains how to work with AI and installs Agent Skills. The AGENTS.md files in Adobe’s repository are for contributors, so the docs section is what earns the Yes.
• Typed props: Yes. S2 ships TypeScript types, and each component page, such as Button (opens in a new tab), has an API table with each prop’s type and default.

Spectrum 2 is split across React Spectrum S2 and two generations of Spectrum Web Components, each with its own site. The research rated S2, and found that the docs and guidance hold for the web components too (their build with AI page (opens in a new tab)). It did not open a separate MCP page for the web components, or check whether their second generation ships types. Adobe also lists a Spectrum Design Data MCP and an S2 docs MCP in its design data repository; the rating rests on the React Spectrum server alone. The code and the design tokens package are under Apache 2.0.

Enterprise apps built in React with S2, or with Spectrum’s web components, where Adobe’s look is the right one and the agent should get its components, its design tokens and its rules from Adobe’s own files.

• Which Spectrum your code uses. A pilot on the web components should confirm the server and the types first.
• That the agent reads the Markdown copy of each page, not the HTML, and loads the design tokens from the package, not from a page.
• How far theming goes: Spectrum’s rules describe Adobe’s product, not yours.

Spectrum shows how much an agent can be given from public files. If your product needs its own look instead of Adobe’s, a custom AI-ready design system carries the same five parts with your design tokens and your rules.
