Part 3. Five more plugins for Claude Cowork that quietly do real work for you. For each one you get what it is best for, a power-user move most people miss, and a deep copy-paste prompt you can run today.
First, A Quick Refresher
Claude Cowork is the space inside the Claude app where Claude builds, edits, and works on files with you. A plugin turns Claude into a specific kind of worker, instead of a blank chat you get a focused helper that knows one job well. If you have never opened the plugin directory, you are using a small slice of what Claude can do.
Plugins are available on paid plans, and you add them from the plugins directory inside Cowork. This is Part 3, so here are five more that most people never touch.
Connect your workspace and Claude reads across every channel and DM, so “what did I miss” gets answered in seconds instead of an hour of scrolling. You ask in plain language, it hands back the decisions, action items, and anything with your name on it.

Pro Move
Slack also powers the Enterprise Search plugin. Connect both, then ask one question across Slack, email, and your docs at once. Claude pulls the answer from wherever it lives and tells you which tool each part came from. Most people run Slack alone and never find this.
Copy-Paste Prompt
The Data plugin (sometimes called the data analyst) turns numbers into something you can act on. Drop in a spreadsheet and it builds a clean dashboard, or turns the raw figures into a story you can put in front of anyone. It writes the SQL and runs the analysis under the hood, and connects to a warehouse if you have one. You just ask the question you care about.

Pro Move
Stop asking for “insights.” That gets you a generic recap. Instead ask it to rank what changed most versus last period and why, and have it flag anything that looks like an error in your data. Even better, chain it: pull an export with Slack or Enterprise Search first, then hand it straight to Data so the chart is built from the real source, not a file you exported by hand.
Copy-Paste Prompt
Connect your Figma files and Claude reads the actual design, not a screenshot. It produces developer-ready handoff specs (the measurements, spacing, colors, and component states a developer needs) and can scaffold the front-end code straight from the file. Designers and developers stop translating the design back and forth, because the spec and the starter code come from the source.

Pro Move
The handoff is not the end of the chain. Take the spec Figma produces and feed it into the Product Management plugin so your PRD, acceptance criteria, and the actual design stay in sync from one source. Most people stop at the handoff doc. Chaining it means the spec your developer builds and the spec your PM wrote are the same spec.
Copy-Paste Prompt
When your work is scattered across a dozen apps, this one finds anything in a single question. Enterprise Search reads all of your connected tools at once (email, Slack, docs, wikis, project trackers) so you stop digging through your inbox, then Slack, then three docs separately. You ask once, and Claude pulls the answer from wherever it lives and tells you the source.
Best For
Pro Move
Always make it cite the source for every claim, so you can trust the answer and click straight to it. Then chain it: use Enterprise Search to gather everything on a topic, then hand that to the Data plugin to chart it or the Product Management plugin to turn it into a doc. Search finds the truth scattered everywhere, the next plugin turns it into the thing you actually needed.
Copy-Paste Prompt
This handles the writing-heavy parts of the PM job. It drafts specs and PRDs, plans roadmaps, and synthesizes user research into clear themes, so you spend less time on busywork and more time deciding what to build. It connects to the tools PMs already live in (your tracker, your design files, your product analytics) so the work is grounded in your real context, not a generic template.
Best For
Pro Move
Run the whole front of the job in one pass: feed it raw user-research notes and have it synthesize the themes first, then write the PRD from those themes, so the spec is grounded in what users actually said. This is the end of the chain. Pair it with Enterprise Search to gather the context and Figma to sync the design, and your research, spec, and design all come from one source instead of three documents that quietly disagree.
Copy-Paste Prompt
It takes about a minute, and you only do it once per plugin.
Step 01
Open Cowork
In the Claude app, open Cowork. This is where Claude builds and edits files, and where your plugins live.
Step 02
Open the plugins directory
Go to the plugins directory and browse what is available. Plugins are on paid plans.
Step 03
Install and connect
Pick the plugin you want and hit Install. If it uses a tool like Slack, Figma, or your data warehouse, connect that account once. Then start asking.
Where to Start
If you only try one, start with the one that matches where your work piles up. Drowning in messages? Slack. Buried in tabs? Enterprise Search. Living in spreadsheets? Data. You can always add the rest later.
