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 | $0.00039 | $0.04476 |
| Opus 5 | $0.00019 | $0.02238 |
| Sonnet 5 | $0.00008 | $0.00895 |
| Haiku 4.5 | $0.00004 | $0.00448 |
Grade A, and why
ui-toolkit/web 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 3d 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.

Overview
The Zoom Video SDK UI Toolkit is a pre-built video UI library that renders complete video conferencing experiences with minimal code. Unlike the raw Video SDK, the UI Toolkit provides:
- ✅ Ready-to-use UI - Professional video interface out of the box
- ✅ Zero UI code - No need to build video layouts, controls, or participant management
- ✅ Framework agnostic - Works with React, Vue, Angular, Next.js, vanilla JS
- ✅ Highly customizable - Choose which features to enable, customize themes
- ✅ Built-in features - Chat, screen share, settings, virtual backgrounds included
When to use UI Toolkit:
- You want a complete video solution quickly
- You need Zoom-like UI consistency
- You don't want to build custom video UI
- You need standard features (chat, share, participants)
What ships with it
3 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.
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.

ui-toolkit/web is a skill published in the GitHub repository zoom/zoom-plugin (7 stars, last pushed 26d ago), licensed MIT. It adds 39 tokens to every session and 4,476 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 2026-08-30.
