The Claude Cowork Setup That Actually Works

Most people use Cowork like a chatbot. That’s why it disappoints them.

I’ve been using Claude Cowork since launch day. It’s now the first thing I open every morning.

Not because I’m an AI enthusiast. Because it keeps finishing work I used to spend hours doing myself.

But here’s what took me weeks to learn: Cowork out of the box is mediocre. Cowork properly configured is a different tool entirely.

The gap between those two is about 30 minutes of setup.


The Problem

Cowork has no memory between sessions. Every conversation starts fresh. It doesn’t know who you are, what you do, or how you like things done.

So it produces generic output. You get frustrated. You assume the tool is overhyped.

The fix isn’t better prompts. It’s better setup.

Five things that actually matter:

  1. Context files — Documents that tell Cowork who you are and how you work

  2. Global instructions — Preferences that load automatically every session

  3. Folder instructions — Project-specific context that loads when you select a folder

  4. Plugins — Specialist packs for your specific role (Marketing, Sales, Finance, Legal, Data)

  5. Connectors — Live integrations with Slack, Drive, Notion, and 50+ tools

Configure these once. Every session after that starts with Cowork already understanding your context.


Let me show you exactly how to set each one up. I’ve put together the Ultimate Setup Guide, including:

Part 1: The Context Files System

Three files that make Cowork actually understand you. Exact templates. What to include. What to skip.

  • about-me.md template

  • brand-voice.md template

  • working-style.md template

Part 2: Global Instructions

Copy-paste instructions I use. The specific phrasings that produce better behavior.

Part 3: Folder Instructions

How to set up project-specific context so each client folder loads its own brief automatically.

Part 4: The Clarifying Questions Prompt

The exact prompt structure that triggers useful questions instead of Cowork guessing wrong.

Part 5: Plugin Setup by Role

Which plugins to install based on what you do. First prompts for each one.

  • Content creators: Marketing + Productivity

  • Salespeople: Sales + Productivity

  • Analysts: Data Analysis + Productivity

  • Founders: Finance + Productivity

  • Legal: Legal + Productivity

Part 6: Connector Strategy

Which tools to connect first. How to prompt Cowork to actually use them.

Part 7: 10 Ready-to-Use Workflows

Copy-paste prompts for:

  1. Weekly planning

  2. Meeting prep from calendar + email + web

  3. Document drafting in your voice

  4. Research synthesis

  5. Content pipelines

  6. Data analysis with recommendations

  7. Client deliverables

  8. Email drafting

  9. Report building

  10. Status updates
