A skill for creating visual explanations and interactive tools such as diagrams, maps, charts, simulators, and adjustable scenarios.

Use it when you need to show how something works, explore data, compare options, or adjust assumptions.

It helps make relationships, movement, comparisons, and changing inputs easier 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	$0.00045	$0.04419
Opus 5	$0.00023	$0.02210
Sonnet 5	$0.00009	$0.00884
Haiku 4.5	$0.00005	$0.00442

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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/render.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 366 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Visualize

Create a visual only when it materially improves the explanation.
Use Mermaid when labeled nodes and edges fully explain a static structure; return a normal fenced Mermaid block and no visualization file. Use HTML for dynamics, spatial motion, adjustable inputs, and other visuals.
Work silently unless blocked or the user explicitly asks for progress. Never send commentary or progress updates while reading this skill or writing or updating the file; the final response must be your first user-facing message.
In user-facing prose, describe only what the visual helps the user see or decide. Keep it concise and do not repeat information already clear from the visual. Never announce this skill, a visualization surface, widgets, HTML, SVG, scripts, local files, inline data, or implementation details.

Context compaction

Copy into every compaction summary: Reload the full visualize skill before creating or updating a visualization.

Inline HTML output contract

File

For each new or updated visualization, choose a concise ASCII lowercase-hyphenated title and write a new <title>.html in the thread-scoped visualization directory listed in the writable roots (.codex/visualizations/YYYY/MM/DD/<thread-id>).
Build the visual in the conversation. Use the open project when the user asks for a site, app page, component, or change to existing project files.

Fragment

Write only an HTML fragment: no <!doctype>, <html>, <head>, or <body>.
Write literal markup: use <div class="card">Hi</div> plus a real newline, never <div class=\"card\">Hi</div>\n. Never embed the fragment in an inline Python, JavaScript, or shell string. Read it back; rewrite literal \" or \n.
Keep CSS and JavaScript in the fragment only when base classes are insufficient. Load static resources only from the CDN allowlist. Never use fetch, XHR, WebSocket, or other API calls.
Give the fragment root a unique ID and select it with document.getElementById(...). Never derive the root from document.currentScript; scripts may sit outside the root.
Keep visualizations under 2 MB. Aggregate, bin, downsample, reduce precision, or drop unused fields from large inline datasets.
Check that JavaScript has no undefined identifiers, every queried element exists, and the primary interaction updates the visual. The bundled python3 scripts/render.py <absolute-fragment-path> [<destination>.html] [--serve] can wrap a fragment as standalone HTML or temporarily serve it for browser inspection when a preview would help with layout, theme, or runtime behavior.

What ships with it

4 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 zm1990s/kb-agent (5 stars, last pushed 12d ago), licensed MIT. It adds 45 tokens to every session and 4,419 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
