live-artifact

live-artifact is a skill for Claude Code, Codex from nexu-io/open-design. It costs 42 tokens per session (1,939 once invoked), scanned A, original, Apache-2.0.

A refreshable HTML artifact whose displayed information comes from local or connected data. The presentation can be updated later without redesigning the page.

In plain words
What is it for?
Use it for live dashboards, synced status pages, refreshable reports, and auditable data views.
Why use it?
It prevents a report or dashboard from becoming outdated after its first creation.

About the project

OpenDesign is an open-source, local-first desktop app that lets coding agents create prototypes, dashboards, slide decks, images, video, and design systems as exportable files. It is used by people working with agent runtimes such as Claude Code, Codex, Cursor, and DeepSeek Harness. The catalogue add-ons extend the OpenDesign workflow with skills, instructions, commands, and plugins.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

live-artifact scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Live Artifact Skill

Create an OpenDesign live artifact: a project-scoped, previewable HTML artifact whose data can later be refreshed without redesigning the presentation.

Current status

Use the references in this directory as the source of truth for the live artifact file contract. Prefer daemon wrapper commands over raw HTTP when registering or updating live artifacts.

When to use this skill

Use this skill when the user asks for a data-backed view that should remain useful after the first render, for example a live dashboard, refreshable report, synced status page, auditable data view, or artifact that can later be refreshed from local/project data or connectors.

Before creating files, decide whether the user actually wants a live artifact or a normal static artifact:

  • Use a live artifact when the user mentions refresh, sync, recurring updates, connector-backed data, source/provenance tracking, dashboards, reports, or reusable data-backed views.
  • Use a normal static artifact when the user only wants a one-off HTML/mockup/image/file and does not need refresh, source metadata, or data/provenance panels.
  • If the intent is ambiguous, ask one short question: “Should this be refreshable/live, or just a static artifact?”

Workflow

  1. Resolve scope and data source without blocking on connected connectors
    • Identify the preview goal, audience, data freshness expectations, and whether refresh should be possible later.
    • If the user explicitly names a connector/source such as Notion, GitHub, Slack, or Google Drive, do not ask “where should the data come from?” before checking daemon connector tools.
    • Prefer local/project sources or daemon connector tools when available.
    • Do not call provider APIs directly when a daemon connector/wrapper exists.
    • If connector data is needed, first list connectors with "$OD_NODE_BIN" "$OD_BIN" tools connectors list --format compact. If the named connector is present with status: "connected", choose an appropriate read-only auto tool from its catalog and execute it through the connector wrapper.
    • For Notion specifically, a connected notion connector plus a user brief that names Notion is enough to start with notion.notion_search using a query derived from the requested artifact/topic. Use notion.notion_fetch_database only when the user supplied a database id or the search result clearly identifies one.
    • Ask the user a data-source question only when no matching connected connector exists, multiple connected candidates fit equally well, or the requested artifact has no usable topic/query to search for. If you must ask, be specific: ask for the page/database/topic or permission to search broadly, not “where is the Notion data source?”

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

live-artifact is a skill published in the GitHub repository nexu-io/open-design (95,021 stars, last pushed today), licensed Apache-2.0. It adds 42 tokens to every session and 1,939 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
