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 | $0.00054 | $0.00730 |
| Opus 5 | $0.00027 | $0.00365 |
| Sonnet 5 | $0.00011 | $0.00146 |
| Haiku 4.5 | $0.00005 | $0.00073 |
Grade A, and why
vendor-review 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 yesterday.
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.

Evaluate a vendor with structured analysis covering cost, risk, performance, and fit.
Usage
/vendor-review $ARGUMENTS
What I Need From You
- Vendor name: Who are you evaluating?
- Context: New vendor evaluation, renewal decision, or comparison?
- Details: Contract terms, pricing, proposal document, or current performance data
Evaluation Framework
Cost Analysis (Total Cost of Ownership)
- Total cost of ownership (not just license fees)
- Implementation and migration costs

- Support response times
- Uptime and reliability
- Feature delivery cadence
- Customer satisfaction
Comparison Matrix
When comparing vendors, produce a side-by-side matrix covering: pricing, features, integrations, security, support, contract terms, and references.

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.
