Validate DESIGN.md files against the official Google specification using the `@google/design.md` CLI linter. Works with local files. Use when the user wants to lint a DESIGN.md, check spec compliance, find broken token references, verify WCAG contrast ratios, diff two versions, export tokens to Tailwind or DTCG format, or audit a design system file for structural correctness. Trigger on mentions of "validate DESIGN.md", "lint DESIGN.md", "check my design.md", "design.md spec compliance…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# design-md-validator
Validate, lint, diff, and export DESIGN.md files using the official Google
`@google/design.md` CLI. Always uses the latest published version from npm —
no vendored copy, always up-to-date with the spec.
---
## When to Use
| Trigger | Action |
|---|---|
| User has a DESIGN.md file and wants validation | `lint` |
| User wants to compare two versions | `diff` |
| User wants to export tokens to Tailwind/DTCG | `export` |
| User wants to see the current spec | `spec` |
| User shares a URL to a raw DESIGN.md | Download locally first |
| User asks "is my design.md valid?" | `lint` + interpret findings |
---
## Core Commands
All commands use `npx @google/design.md` to ensure the latest version is always
used. Never install globally — `npx` resolves from the public npm registry.
### Lint (validate)
```bash
npx @google/design.md lint DESIGN.md
```
Output: JSON with `findings[]` and `summary { errors, warnings, infos }`.
Exit code 1 if errors found, 0 otherwise.
### Diff (compare versions)
```bash
npx @google/design.md diff DESIGN.md DESIGN-v2.md
```
Output: JSON with token-level changes (added, removed, modified) and regression flag.
…Read the whole file at its exact version.
How to install
mdr add fabricioctelles/skills/design-md-validator@sha256:aed52073f4331ee6The line at the top of this page pins the label v1.4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
