frontend-design skillA

frontend-design is agent-read markdown (skill) from vellum-ai/vellum-assistant: Design-quality layer for frontend code — typography, color, motion, spatial composition, and avoiding generic "AI slop" aesthetics. Use this as a companion when you are already writing or styling frontend code and want it to look distinctive and production-grade. For building an app, dashboard, tracker, calculator, visualization, landing page, or slide deck the user wants inside the assistant, load `app-builder` instead — it loads this skill itself for the design pass..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add vellum-ai/vellum-assistant/frontend-design@git:20260903.5802532
Exact content
mdr add vellum-ai/vellum-assistant/frontend-design@sha256:a5942fcd29d847fd

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
