frontend-ui-engineering skillA

frontend-ui-engineering is agent-read markdown (skill) from addyosmani/agent-skills: Builds production-quality, accessible, responsive user-facing UIs. Use when building or modifying interfaces and pages, creating components, implementing layouts, meeting WCAG accessibility requirements, managing state, or when the output needs to look and feel production-quality rather than AI-generated..

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 addyosmani/agent-skills/frontend-ui-engineering@git:20260807.91d4d07
Exact content
mdr add addyosmani/agent-skills/frontend-ui-engineering@sha256:2b74ac4862be3902

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.
