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.

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 | $0.00038 | $0.01309 |
| Opus 5 | $0.00019 | $0.00655 |
| Sonnet 5 | $0.00008 | $0.00262 |
| Haiku 4.5 | $0.00004 | $0.00131 |
Grade A, and why
setup-zoom-webhooks 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/setup-zoom-webhooks
Background reference for Zoom event delivery over HTTP. Prefer workflow skills first, then use this file for verification, subscription, and delivery details.
Prerequisites
- Zoom app with Event Subscriptions enabled
- HTTPS endpoint to receive webhooks
- Webhook secret token for verification
Need help with authentication? See the zoom-oauth skill for OAuth setup.
Quick Start
// Express.js webhook handler
const crypto = require('crypto');
// Capture raw body for signature verification (avoid re-serializing JSON).
app.use(require('express').json({
verify: (req, _res, buf) => { req.rawBody = buf; }
}));
app.post('/webhook', (req, res) => {
// Verify webhook signature
const signature = req.headers['x-zm-signature'];
const timestamp = req.headers['x-zm-request-timestamp'];
const body = req.rawBody ? req.rawBody.toString('utf8') : JSON.stringify(req.body);
const payload = `v0:${timestamp}:${body}`;
const hash = crypto.createHmac('sha256', WEBHOOK_SECRET)
.update(payload).digest('hex');
if (signature !== `v0=${hash}`) {
return res.status(401).send('Invalid signature');
}
// Handle event
const { event, payload } = req.body;
console.log(`Received: ${event}`);
res.status(200).send();
});

What ships with it
7 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.
