artifact-design skillB

artifact-design is agent-read markdown (skill) from open-octo/octo-agent: Design guidance for any HTML/Markdown file shown in octo's Artifacts panel — reports, dashboards, architecture/system diagrams, generated UIs, slide-style pages, 3D scenes. Read this BEFORE writing the file, not after — it calibrates how much design effort the request warrants and covers the panel's real constraints (the page runs on its own origin and can reference files beside it, external resources gated to an allowlist of CDN hosts, narrow default width, no live theme push). Use when the use.

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 open-octo/octo-agent/artifact-design@git:20260908.41e9f79
Exact content
mdr add open-octo/octo-agent/artifact-design@sha256:cd15c8455e66128a

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.
