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.

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 | $0.00042 | $0.01113 |
| Opus 5 | $0.00021 | $0.00557 |
| Sonnet 5 | $0.00008 | $0.00223 |
| Haiku 4.5 | $0.00004 | $0.00111 |
Grade A, and why
rivet-sdk 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.

Zoom Rivet SDK
Background reference for Zoom Rivet as a JavaScript and TypeScript server framework for Zoom integrations.
Implementation guidance for Zoom Rivet (JavaScript/TypeScript) as a server-side framework for:
- OAuth and token handling
- Webhook event consumption
- Typed REST API endpoint wrappers
- Multi-module server composition
Official docs:
- https://developers.zoom.us/docs/rivet/
- https://developers.zoom.us/docs/rivet/javascript/
- https://zoom.github.io/rivet-javascript/
Reference samples:
- https://github.com/zoom/rivet-javascript-sample
- https://github.com/zoom/isv-rivet-starter

Routing Guardrail
- Rivet SDK is a Node.js framework that bundles Zoom auth handling, webhook receivers, and typed API wrappers.
- Rivet is recommended for faster server-side scaffolding, but it is not mandatory.
- At planning start, confirm preference:
Do you want Rivet SDK, or direct OAuth + REST without Rivet?- Use Rivet when the user wants a Node.js server that combines Zoom auth + webhooks + API calls with minimal glue code.
- If the user only needs direct API calls from an existing backend, chain with ../rest-api/SKILL.md.
- If the user is focused on Zoom Team Chat app cards/commands behavior, chain with ../team-chat/SKILL.md.
- If the user needs SDK embed (Meeting SDK/Video SDK client runtime), route to ../meeting-sdk/SKILL.md or ../video-sdk/SKILL.md.

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.

rivet-sdk is a skill published in the GitHub repository anthropics/knowledge-work-plugins (23,902 stars, last pushed yesterday), licensed Apache-2.0. It adds 42 tokens to every session and 1,113 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 2026-09-05.
