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.

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 | $0.00065 | $0.02018 |
| Opus 5 | $0.00032 | $0.01009 |
| Sonnet 5 | $0.00013 | $0.00404 |
| Haiku 4.5 | $0.00006 | $0.00202 |
Grade A, and why
sox-testing 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 4d 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 — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SOX Compliance Testing
If you see unfamiliar placeholders or need to check which tools are connected, see CONNECTORS.md.
Important: This command assists with SOX compliance workflows but does not provide audit or legal advice. All testing workpapers and assessments should be reviewed by qualified financial professionals before use in audit documentation.
Generate sample selections, create testing workpapers, document control assessments, and provide testing templates for SOX 404 internal controls over financial reporting.
Usage
/sox <control-area> <period>
Arguments
control-area— The control area to test:revenue-recognition— Revenue cycle controls (order-to-cash)procure-to-payorp2p— Procurement and AP controls (purchase-to-pay)payroll— Payroll processing and compensation controlsfinancial-close— Period-end close and reporting controlstreasury— Cash management and treasury controlsfixed-assets— Capital asset lifecycle controlsinventory— Inventory valuation and management controlsitgc— IT general controls (access, change management, operations)entity-level— Entity-level and monitoring controlsjournal-entries— Journal entry processing controls- Any specific control ID or name
period— The testing period (e.g.,2024-Q4,2024,2024-H2)
Workflow
1. Identify Controls to Test
Based on the control area, identify the key controls. Present the control matrix:
| Control # | Control Description | Type | Frequency | Key/Non-Key | Risk | Assertion |
|---|---|---|---|---|---|---|
| [ID] | [Description] | Manual/Automated/IT-Dependent | Daily/Weekly/Monthly/Quarterly/Annual | Key | High/Medium/Low | [CEAVOP] |
Control types:
- Automated: System-enforced controls with no manual intervention
- Manual: Controls performed by personnel with judgment
- IT-dependent manual: Manual controls that rely on system-generated data
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.

sox-testing 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 65 tokens to every session and 2,018 once invoked, about $0.0003 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 2026-09-03.
