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.

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 | $0.00009 | $0.00233 |
| Opus 5 | $0.00005 | $0.00117 |
| Sonnet 5 | $0.00002 | $0.00047 |
| Haiku 4.5 | $0.00001 | $0.00023 |
Grade A, and why
summarize-channel 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.

What it actually says
Given the channel name provided in $ARGUMENTS (strip any leading #):
- Use the
slack_search_channelstool to find the channel ID for the provided channel name. Strip any leading#from the argument before searching. - Use the
slack_read_channeltool to read recent messages from the channel (default limit of 100 messages). - For any messages that have threads with replies, use
slack_read_threadto read the thread contents so the summary captures threaded discussions. - Produce a concise summary organized by topic or theme. The summary should include:
- An overview of the main topics discussed
- Key decisions or action items mentioned
- Notable announcements or updates
- Active threads and their conclusions (if any)
- Keep the summary scannable — use short bullet points grouped by topic. Mention who said what when it's relevant (e.g., decisions, action items).
- If the channel has very little recent activity, say so and note the last time a message was posted.
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.
