a2ui-compose skillA

a2ui-compose is agent-read markdown (skill) from a2uicatalog/a2ui: Compose an A2UI payload (typed atom blocks) and render it into real HTML — a chart, dashboard, status board, decision tree, or any structured UI, once the right atoms are already known (see the a2ui-catalog skill for picking them). Use when asked to SHOW something rather than describe it, and the host can display HTML or open a link. Not for connecting a new agent/host to the MCP server itself (see a2ui-mcp)..

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 a2uicatalog/a2ui/a2ui-compose@v1.0.0
Exact content
mdr add a2uicatalog/a2ui/a2ui-compose@sha256:d6750d93bb78ee31

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.
