## What is Cowork?

**Cowork** is Anthropic's agentic tool for knowledge workers — think Claude Code, but for non-developers.

It runs in a lightweight Linux VM on your computer, giving Claude the ability to:

- Create and edit documents (Word, Excel, PowerPoint, PDF)
- Browse the web and research topics
- Execute code and scripts
- Connect to external tools via MCP (Model Context Protocol)

**Available on:** Pro and Max plans

## What Are Plugins?

Plugins are **pre-built bundles** that give Cowork superpowers in specific domains.

Each plugin includes:

| Component          | What It Does                                     |
| ------------------ | ------------------------------------------------ |
| **Skills**         | Domain expertise and workflows                   |
| **Slash Commands** | Quick actions (e.g., /review-contract)           |
| **MCP Connectors** | Connect to external tools (CRM, databases, etc.) |
| **Sub-agents**     | Specialized AI workers for specific tasks        |

**Result:** Instead of prompting from scratch, you get instant expertise.

## How to Enable Plugins

### Step 1: Access Cowork

1. Open **Claude.ai** (Pro or Max plan required)
2. Click the **Cowork** button (bottom left)
3. Wait for the VM to initialize

### Step 2: Select a Folder

When prompted, select a folder on your computer. This becomes your workspace where:

- Claude can read/write files
- Outputs are saved
- Context files live

### Step 3: Browse Available Plugins

Plugins appear in the skills list. Check available skills by asking:

```
What skills do you have available?
```

Or look for the `/` slash command menu.

### Step 4: Use Slash Commands

Each plugin comes with slash commands. Examples:

```
/campaign-plan          → Generate a full marketing campaign
/review-contract        → Analyze a contract against your playbook
/write-spec             → Create a PRD from a feature idea
/draft-outreach         → Research prospect + draft personalized email
/journal-entry          → Prepare month-end journal entries
```

## Setting Up Your Personal OS

The most powerful Cowork setup combines plugins with a **Personal Operating System** — a folder structure that gives Claude persistent memory.

### Recommended Folder Structure

```
Claude/
├── CLAUDE.md           ← Attach this to start each session
├── Context/
│   ├── profile.md      ← Your preferences, goals, work style
│   └── projects.md     ← Active projects and status
├── Inbox/              ← Drop files for Claude to process
├── Outbox/
│   └── Daily/          ← Daily briefings saved here
├── Logs/               ← Session logs
└── schedule.md         ← Weekly/monthly recurring tasks
```

### The CLAUDE.md File

This is your "brain file" — attach it to every session. It tells Claude:

- Who you are and how you work
- Your active projects and priorities
- How to run your morning routine
- Where to find/save files

**Pro tip:** Start each day with "Let's start our day" and Claude will:

1. Read your context files
2. Ask what would make today a win
3. Review your todo list
4. Fetch relevant stats (YouTube, LinkedIn, etc.)
5. Create a daily briefing

## MCP Connectors

| **Facebook Ads**     | Campaign insights, ad library search |

3. Follow the OAuth flow to authenticate
4. Connector becomes available in your session

## Power User Tips

### 1\. Stack Plugins for Complex Workflows

Example: Launching a product

```
1. /write-spec → Define the feature
2. /campaign-plan → Plan the launch
3. /draft-content → Create launch content
4. /draft-outreach → Prepare sales enablement
```

### 2\. Use Context Files for Memory

Claude doesn't remember between sessions. Keep critical info in:

- `profile.md` — Your preferences and goals
- `projects.md` — Active work and status
- Domain-specific files — Playbooks, templates, guidelines

### 3\. Create Custom Slash Commands

Use the `/create-shortcut` command to build your own:

```
/create-shortcut "weekly-report" that generates a marketing
performance summary using Google Analytics data
```

### 4\. Batch Similar Tasks

Instead of one-off requests, batch work:

```
Review these 5 contracts and create a summary table
showing risk level, key deviations, and recommended actions
```

### 5\. Let Claude Work Autonomously

For complex tasks, give Claude permission to work through multiple steps:

```
Research our top 3 competitors, create battlecards for each,
and save them to the Outbox folder. Work through this autonomously.
```

---

## Troubleshooting

### "Plugin not found"

→ Check if plugin is enabled in your plan settings

### "Connector not authenticated"

→ Re-authenticate the MCP connector

### "File not saved"

→ Make sure you've selected a workspace folder

### "Context lost between sessions"

→ Attach your CLAUDE.md file at the start of each session
