A Chinese-language guide for creating interactive charts, diagrams, simulations, visual explanations, dashboards, visual comparisons, SVG or Canvas artwork, and interface prototypes in a Nexus conversation.

Use it to build an interactive visual explanation or prototype directly inside a conversation when the visual is more useful than prose.

It helps present relationships or processes visually when ordinary text or a table would be harder to understand.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00076	$0.01134
Opus 5.5	$0.00030	$0.00454
Sonnet 5.5	$0.00015	$0.00227
Haiku 4.5	$0.00008	$0.00113

Security

Grade A, and why

visualize scanned grade A with 0 findings 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 19d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Nexus Generative UI

Create a custom interactive visual only when it communicates the answer better than ordinary prose or a table.

Workflow

Choose the visual form and read only the relevant references below before composing the fragment.
Call show_widget with a concise title and one self-contained HTML fragment in widget_code.
Put explanation and conclusions in the normal response around the widget. Do not repeat the visual as Markdown.
The tool result only confirms delivery to the client. Do not claim that rendering succeeded.

Read on demand

Resolve these paths relative to this skill directory. Do not load the whole reference directory. Combine references only when the widget needs both concerns, such as an interactive diagram.

When building	Read
Controls, selections, or state-driven views	Interaction
Quantitative charts, axes, or Chart.js	Charts
Flows, hierarchies, networks, or explanatory diagrams	Diagrams
Product UI prototypes, dashboards, or comparison layouts	UI mockups
SVG illustrations, Canvas drawing, or continuous animation	Art

Return a fragment only. Do not include html, head, or body tags.
Inline the widget's CSS and JavaScript. SVG, Canvas, DOM, Web Components, and external CDN libraries are supported.
Network access and external resources are allowed without a domain allowlist. Prefer established HTTPS CDNs.
The fragment runs in an isolated iframe and cannot access the Nexus page, cookies, storage, or parent DOM.
To show an image that already exists in the current Agent workspace, use a host reference such as src="nexus://workspace/.cloud-photo/preview.jpg". Nexus resolves this reference through the authenticated workspace preview endpoint before handing the fragment to the isolated iframe. The path is workspace-relative and must not contain an Agent absolute path.
Do not use file://, localhost URLs, absolute workspace paths, or Base64 for workspace images. Those forms either cannot cross the iframe boundary safely or make the model carry large binary payloads.
Streaming order is short style, visible content, then scripts last. Scripts run only after the complete tool input arrives. Keep native controls and static content useful before initialization.
Before calling show_widget, check every inline script for unmatched quotes, backticks, brackets, and incomplete blocks. Prefer short functions over one monolithic script.
Before calling show_widget, verify that every id, class, or data attribute referenced by JavaScript exists in the submitted markup and is spelled identically.
Separate source data, derived calculations, rendering, and event binding. Avoid constructing large interfaces through nested template literals or long HTML string concatenation; update existing DOM nodes when practical.
Use the smallest implementation that fully answers the request. Split independent visuals into separate show_widget calls with short prose between them, but keep one cohesive widget when its views share state.
Make the layout responsive at 320px width and avoid fixed viewport dimensions.
Use accessible labels, keyboard-operable controls, visible focus, and reduced-motion fallbacks.
Keep interaction local to the widget. Do not assume a host API or postMessage bridge.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.

visualize is a skill published in the GitHub repository nexus-research-lab/nexus (152 stars, last pushed today), licensed Apache-2.0. It adds 76 tokens to every session and 1,134 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
