adobe/spectrum-design-data is a monorepo containing the design tokens, component schemas, specifications, and related datasets that define Adobe's Spectrum design system; a monorepo keeps these related packages in one repository. It is for Adobe Spectrum SDK and tooling developers who need canonical design-system data and validation artifacts. The catalogue add-ons provide workflows and integrations for working with this design data.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00255 |
| Opus 5.5 | $0.00000 | $0.00102 |
| Sonnet 5.5 | $0.00000 | $0.00051 |
| Haiku 4.5 | $0.00000 | $0.00026 |
Grade A, and why
design-data-corpus scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Canonical design data
packages/design-data/is the source of truth for token data.sdk/coreembeds it at compile time, so changes requiremoon run sdk:codegenandmoon run sdk:codegen-check.- Validate edits with
moon run design-data:validate. - Reuse existing registry vocabulary (fields, variants, anatomy parts) before adding new ids. Check
lifecycle.deprecatedInandlifecycle.replacedByon legacy tokens before deciding between new vocabulary and aname.legacyKeypin. - Preserve obsolete legacy names with explicit
name.legacyKeypins instead of generalized exceptions. - Do not change canonical values to work around exporter or tooling gaps.
- Token and registry changes are user-facing: add a changeset for
@adobe/spectrum-design-data.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

design-data-corpus is a cursor rule published in the GitHub repository adobe/spectrum-design-data (156 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 255 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-14.
Other cursor rules, from other repositories
designlang
Design system extracted from https://cal.com — use these tokens, do not invent new ones.
sigil-design-system
Every custom preset MUST populate ALL 33 token categories and ALL 519 fields.
taste-enforcement
These dials drive all downstream decisions. Adjust per-prompt when the user specifies a different mood.
dashboard-design
14px is the dashboard base. Not 16px (too editorial), not 13px (too dense). Body text at 14px uses -0.2px letter-spacing.
design-animation-rules
Taste is trained, not innate. Reverse engineer animations. Inspect interactions. Unseen details compound — a thousand barely audible voices all singing in tune. Beauty is leverage.
interface-micro-polish
Nested surfaces must be mathematically related: outer radius = inner radius + padding.
