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.

SkillSpector: 7 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00037 | $0.07580 |
| Opus 5 | $0.00018 | $0.03790 |
| Sonnet 5 | $0.00007 | $0.01516 |
| Haiku 4.5 | $0.00004 | $0.00758 |
Grade A, and why
zoom-oauth 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 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.

Four Authorization Use Cases
| Use Case | App Type | Grant Type | Industry Name |
|---|---|---|---|
| Account Authorization | Server-to-Server | account_credentials |
Client Credentials Grant, M2M, Two-legged OAuth |
| User Authorization | General | authorization_code |
Authorization Code Grant, Three-legged OAuth |
| Device Authorization | General | urn:ietf:params:oauth:grant-type:device_code |
Device Authorization Grant (RFC 8628) |
| Client Authorization | General | client_credentials |
Client Credentials Grant (chatbot-scoped) |
Industry Terminology
| Term | Meaning |
|---|---|
| Two-legged OAuth | No user involved (client ↔ server) |
| Three-legged OAuth | User involved (user ↔ client ↔ server) |
| M2M | Machine-to-Machine (backend services) |
| Public client | Can't keep secrets (mobile, SPA) → use PKCE |
| Confidential client | Can keep secrets (backend servers) |
| PKCE | Proof Key for Code Exchange (RFC 7636), pronounced "pixy" |

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.
- 3d ago First seen · 902 lines · 37 tokens per session scan A 126c291d7d80
zoom-oauth is a skill published in the GitHub repository anthropics/knowledge-work-plugins (23,920 stars, last pushed 3d ago), licensed Apache-2.0. It adds 37 tokens to every session and 7,580 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.
