artifact-design SKILL.md skillB
artifact-design from open-octo/octo-agent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add open-octo/octo-agent/artifact-design@git:20260923.bfb1a61Pins git:20260923.bfb1a61 in mdr.lock. Pin the fingerprint instead.

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 is a real web page that can reference files beside it by relative path, narrow default width, no live theme push). Use when the user asks to "画架构图" / "generate a diagram…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Artifact design An artifact is any `.html`/`.htm`/`.md`/`.markdown`/`.png`/`.jpg`/`.jpeg`/`.gif`/`.svg`/`.webp` file the agent produces. Writing one through `write_file`/`edit_file` surfaces it automatically in the web UI's Artifacts panel; a file built some other way (a script, a build step, a download) needs one `show_artifact` call with its absolute path. This skill is about what to put *inside* the HTML — read it before writing the first line. If the page contains any chart, graph, plot, heatmap, sparkline, or stat tile, read `references/charts.md` before writing the chart — chart-type selection, the color system (with a validated default palette in `references/palette.md`), legend/axis/tooltip conventions, and chart legibility at the panel's docked width. ## How the panel actually works — design within these constraints - **The page is a real web page.** HTML renders inside a frame from a path on octo's own address, so everything a normal web page can do works: `localStorage` persists (the page's keys are kept apart from octo's own and from other pages'), `<a download>` saves a file, `requestFullscreen()` and …

How to install
mdr add open-octo/octo-agent/artifact-design@sha256:5d6d650b0c1463b1The line at the top of this page pins the label git:20260923.bfb1a61, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
