contact-widget skillB

contact-widget is agent-read markdown (skill) from nexu-io/open-design: Self-contained floating chat widget with welcome screen, social links, meeting button, and message input. Single HTML file, zero dependencies..

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 nexu-io/open-design/contact-widget@git:20260731.ebcba70
Exact content
mdr add nexu-io/open-design/contact-widget@sha256:dfa37f9b220327a9

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.
