Automatically run after any edit to a .css, .tsx, .ts, .jsx, or .js file that touches styling, and before every commit that touches styles or components. Checks the diff against the design system tokens and living style guide. Trigger on: new CSS rules, className changes, style props, "check this against the design system".
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
## When to invoke (auto-trigger) Invoke this skill automatically whenever: - Any `.css` file is edited - A `.tsx` / `.jsx` file is edited and the diff contains `className`, `style=`, or CSS custom properties - A new component is created - A new CSS class is introduced Do NOT wait for the user to ask. Run as part of the normal post-edit flow for any styling change. A `PostToolUse` hook (`~/.claude/hooks/ds-guard-trigger.py`, wired in `~/.claude/settings.json`) now fires deterministically on every styling-file edit and injects a reminder, so the trigger no longer depends on this description matching. Effort gating: at `high`/`xhigh`/`max` run the full audit against the token inventory and showcase (Steps 1+); at lower effort a quick spot-check of the diff's hardcoded values is enough. # DS Guard — Design System Enforcement ## Purpose Audit a diff or set of files to ensure every styling decision goes through the project's design system token layer. Catch violations before they land. ## Step 1 — Discover the token inventory Find the project's token source files: - Look for `src/lib/theme/themes/*.css`, `tokens.css`, `design-tokens.*`, or similar …

How to install
mdr add jerseycheese/agent-skills/ds-guard@sha256:bbaaf98a09c48b2cThe line at the top of this page pins the label git:20261016.04e815b, 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.
