Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00095 | $0.05012 |
| Opus 5 | $0.00048 | $0.02506 |
| Sonnet 5 | $0.00019 | $0.01002 |
| Haiku 4.5 | $0.00010 | $0.00501 |
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.
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 — 415 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Inline Visualizer
Render rich interactive visuals directly inline in chat using render_visualization.
How to use
- Call
render_visualization(html_code, title)with an HTML or SVG content fragment - Do NOT include
<!DOCTYPE>,<html>,<head>, or<body>— the tool wraps your content automatically - Structure:
<style>first (prefer inline styles) → visible content →<script>last - The tool auto-injects: theme CSS, SVG classes, color ramps, height reporting,
sendPrompt()bridge, andopenLink()bridge - Consider making diagrams conversational with
sendPrompt()— see the sendPrompt bridge section for patterns and examples
Output rules
These rules keep visuals clean, accessible, and consistent with the host UI:
- Flat design — no gradients, drop shadows, blur, glow, or noise textures (the host UI is flat; matching it prevents visual jarring)
- No emoji — use CSS shapes or SVG paths for icons (emoji render inconsistently across platforms)
- Sentence case — all labels and headings
- Round displayed numbers — use Math.round, toLocaleString, or Intl.NumberFormat
- Min font size 11px — smaller becomes unreadable on most screens
- Text weights — 400 regular, 500 for emphasis only
- All explanatory text goes in your prose response, not inside the visual (keeps visuals data-dense and lets the model's response provide context)
Design system
CSS variables (auto-injected — always use these, never hardcode colors)
The tool injects theme-aware CSS variables that automatically adapt to light/dark mode. Hardcoding hex colors will break in one mode or the other.

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.
- 2d ago First seen · 415 lines · 95 tokens per session scan A 19722ef0fb5f
visualize is a skill published in the GitHub repository Classic298/open-webui-plugins (533 stars, last pushed 7d ago), licensed BSD-3-Clause. It adds 95 tokens to every session and 5,012 once invoked, about $0.0005 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 2026-08-30.
