Claude Coworks Installation

This guide walks you through installing ExtraSuite skills for Claude Coworks, Anthropic's collaborative AI workspace.

Prerequisites

  1. Claude Coworks access - Available through claude.ai/coworks
  2. Active Claude subscription (Pro or Team plan required)
  3. Terminal access for initial setup (macOS, Linux, or Windows)

What is Claude Coworks?

Claude Coworks is Anthropic's collaborative workspace that allows Claude to work on longer tasks with persistent context. Unlike Claude Code which runs in your terminal, Coworks runs in a browser-based environment.

Installation

Step 1: Sign In to ExtraSuite

  1. Open extrasuite.think41.com
  2. Click Sign In or Get Started
  3. Authenticate with your Google Workspace account
  4. Note your service account email - you'll need this for sharing documents

Step 2: Run the Install Command

The install command sets up skills that work across all Claude products:

curl -fsSL https://extrasuite.think41.com/api/skills/install/<your-token> | bash

irm "https://extrasuite.think41.com/api/skills/install/<your-token>?ps=true" | iex

Step 3: Using with Coworks

In Claude Coworks, you can reference the skill in your prompts:

I need to work with Google Sheets. Use the gsheets skill to read and
analyze the data in https://docs.google.com/spreadsheets/d/abc123/edit

Coworks Environment

Claude Coworks may have its own skill discovery mechanism. The local installation ensures compatibility and provides the skill files that Coworks can reference.

How It Works

When working in Coworks:

  1. Mention the spreadsheet URL in your prompt
  2. Claude recognizes it needs Google Sheets access
  3. Authentication happens seamlessly using your ExtraSuite credentials
  4. Claude executes the requested operations

Usage Examples

Long-Running Analysis

Analyze the customer data in https://docs.google.com/spreadsheets/d/abc123/edit
over the past 12 months. Create monthly cohort analysis, identify trends,
and generate a summary report with recommendations.

Multi-Step Workflows

1. Read the raw sales data from https://docs.google.com/spreadsheets/d/abc123/edit
2. Clean and normalize the data
3. Create a new sheet with aggregated metrics
4. Add charts for visualization
5. Write a summary of key findings

Collaborative Document Updates

I'm preparing a quarterly report. Update the metrics sheet at
https://docs.google.com/spreadsheets/d/abc123/edit with the
following data: [your data]

Then format it with proper headers and conditional formatting.

Sharing Documents with Coworks

Since Coworks sessions may run longer than typical Claude Code sessions, make sure to:

  1. Share documents with Editor access if you want Claude to make changes
  2. Use specific, shared folders for related documents
  3. Keep your service account email handy for quick sharing

Skill Location

The skill files are installed to:

~/.claude/skills/gsheets/

Coworks shares skill configurations with Claude Code.

Updating the Skill

To update to the latest version, re-run the install command from the ExtraSuite homepage.

Troubleshooting

Coworks Can't Access the Spreadsheet

  1. Verify the document is shared with your service account email
  2. Check that the sharing permission is set to Editor (not just Viewer)
  3. Make sure the spreadsheet URL is correct and accessible

Authentication Issues

If you encounter authentication problems:

  1. Clear your browser cookies for extrasuite.think41.com
  2. Re-authenticate through the ExtraSuite homepage
  3. Re-run the install command to refresh your credentials

Session Timeout

Coworks sessions can be long-running. If you encounter token expiration:

  1. Claude will automatically handle re-authentication
  2. You may be prompted to re-authorize if the session exceeds token lifetime
