Knowledge Work Plugins is an open-source collection of Claude extensions organized around roles such as productivity, sales, and customer support. Each plugin combines role-specific guidance, connectors, commands, and sub-agents so knowledge workers can use Claude with their team’s tools and processes. The catalogue entries are examples of, or workflows from, this plugin collection.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.
git clone --depth 1 https://github.com/anthropics/knowledge-work-pluginsnpx agentmods add skills/anthropics/knowledge-work-plugins/video-sdkWrote this? Show the measurements
A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00039 | $0.03317 |
| Opus 5 | $0.00019 | $0.01658 |
| Sonnet 5 | $0.00008 | $0.00663 |
| Haiku 4.5 | $0.00004 | $0.00332 |
Grade A, and why
build-zoom-video-sdk-app 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 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.

How it starts
The opening of the file, as written. The whole thing — 373 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/build-zoom-video-sdk-app
Background reference for fully custom video-session products. Prefer plan-zoom-product first when the boundary between Meeting SDK and Video SDK is still unclear.
Build custom video experiences powered by Zoom's infrastructure.
Hard Routing Guardrail (Read First)
- If the user asks for custom real-time video app behavior (topic/session join, custom rendering, attach/detach), route to Video SDK.
- Do not switch to REST meeting endpoints for Video SDK join flows.
- Video SDK does not use Meeting IDs,
join_url, or Meeting SDK join payload fields (meetingNumber,passWord).
Meeting SDK vs Video SDK
| Feature | Meeting SDK | Video SDK |
|---|---|---|
| UI | Default Zoom UI or Custom UI | Fully custom UI (you build it) |
| Experience | Zoom meetings | Video sessions |
| Branding | Limited customization | Full branding control |
| Features | Full Zoom features | Core video features |
UI Options (Web)
Video SDK gives you full control over the UI:
| Option | Description |
|---|---|
| UI Toolkit | Pre-built React components (low-code) |
| Custom UI | Build your own UI using the SDK APIs |
Prerequisites
- Zoom Video SDK credentials from Marketplace
- SDK Key and Secret
- Web development environment
Need help with OAuth or signatures? See the zoom-oauth skill for authentication flows.
Need pre-join diagnostics on web? Use probe-sdk before Video SDK
join()to reduce first-minute failures.
Start troubleshooting fast: Use the 5-Minute Runbook before deep debugging.
Quick Start (Web)
NPM Usage (Bundler like Vite/Webpack)
import ZoomVideo from '@zoom/videosdk';
const client = ZoomVideo.createClient();
await client.init('en-US', 'Global', { patchJsMedia: true });
await client.join(topic, signature, userName, password);
// IMPORTANT: getMediaStream() ONLY works AFTER join()
const stream = client.getMediaStream();
await stream.startVideo();
await stream.startAudio();
What ships with it
60 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.
- 2d ago First seen · 373 lines · 39 tokens per session scan A 0c2e14022346
build-zoom-video-sdk-app is a skill published in the GitHub repository anthropics/knowledge-work-plugins (23,911 stars, last pushed 2d ago), licensed Apache-2.0. It adds 39 tokens to every session and 3,317 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 2026-09-05.
