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
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.

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 | $0.00039 | $0.04420 |
| Opus 5.5 | $0.00016 | $0.01768 |
| Sonnet 5.5 | $0.00008 | $0.00884 |
| Haiku 4.5 | $0.00004 | $0.00442 |
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 1mo 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.
Copies of this mod
2 near-identical copies found in the catalogue:

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.
