Anthropic Launches Cowork Plugins: Claude Becomes Your All-in-One Work Assistant

Release Date: January 30, 2026

Anthropic has announced the launch of “plugins” (Skills) for its Cowork tool, further advancing into the realm of agentic AI. These plugins enable Claude to act as a “domain expert” across various fields, from sales and legal to biology research, covering 9 professional domains. The feature is now available in research preview to all paid subscription tiers.

🎯 What is Cowork?

From Claude Code to Cowork

When Anthropic released Claude Code, they expected developers to use it for coding. They did—and then quickly began using it for almost everything else. This prompted Anthropic to build Cowork: a simpler way for anyone—not just developers—to work with Claude in the very same way.

Core Capabilities of Cowork

In Cowork, you give Claude access to a folder of your choosing on your computer. Claude can:

Read files - Understand file content and structure
Edit files - Modify existing documents
Create files - Generate new documents, spreadsheets, presentations

Typical Use Cases:

Reorganize your downloads by sorting and renaming each file
Create a new spreadsheet with a list of expenses from a pile of screenshots
Produce a first draft of a report from your scattered notes
