Written for GitHub Copilot: a Copilot instructions file.

This is adobe/spectrum-design-data's own configuration. It tells GitHub Copilot how to work on spectrum-design-data itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything spectrum-design-data configures →

About the project

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

spectrum-design-data design-data-corpus.instructions.md 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 6d 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/core embeds it at compile time, so changes require moon run sdk:codegen and moon 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.deprecatedIn and lifecycle.replacedBy on legacy tokens before deciding between new vocabulary and a name.legacyKey pin.
  • Preserve obsolete legacy names with explicit name.legacyKey pins 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.
Changes

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.
