Claude Cowork Skills: What They Are and How to Use Them
Skills give Claude Cowork specialized abilities like building Word docs, spreadsheets, and slide decks. How they differ from plugins and connectors.
Skills are bundles of specialized know-how that teach Claude Cowork to do a specific kind of task really well, like producing a properly formatted Word document, Excel spreadsheet, or PowerPoint deck. Claude picks the right skill automatically when your request matches it, so you mostly just ask for the outcome and the skill handles the how.
If plugins are Cowork’s app store, skills are the individual capabilities inside. They’re the reason Cowork hands you a real, properly formatted document instead of a wall of text that says “here is roughly what your report could look like.”
What a skill actually is
A skill is a bundle of specialized know-how that teaches Cowork to do one kind of task well. Think of it as a recipe card plus the right kitchen tools. When you ask for something that matches a skill, like a formatted spreadsheet, Claude grabs that skill and follows it, so the output comes out finished instead of improvised.
The practical part: you usually don’t think about skills at all. You ask for the outcome (“turn these notes into a slide deck”), and Cowork figures out which skill fits and uses it. The skill handles the fiddly formatting work in the background while you get the file.
Skills you will run into
The most common built-in skills cover the documents everyone actually makes:
- Word documents. Real .docx files with headings, tables, and proper formatting, not a text dump.
- Spreadsheets. Excel files with formulas, formatting, and clean tabs.
- Slide decks. PowerPoint presentations built from your source material.
- PDFs. Creating, filling, merging, or pulling data out of them.
These are the workhorses. They’re why “make me a report” produces an actual report. For more of what Cowork can do with them, see our use cases guide.
Skills vs plugins vs connectors
These three words get tangled, so here’s the clean version:
| Term | What it is | Plain analogy |
|---|---|---|
| Skill | A specific capability, like building a deck | A talent |
| Plugin | A package that bundles skills and tools to install | An app you add |
| Connector | A bridge to an outside app, like email or a database | A power cord |
A skill is the talent, a plugin is how you install talents, and a connector is how Cowork reaches your other tools. Our guide to Claude Cowork plugins covers the installation side.
How to use skills
The honest instructions are short: describe what you want. Ask for a Word report and the document skill kicks in. Ask for a budget spreadsheet and the spreadsheet skill does. You can be specific about format (“as a PowerPoint, four slides”) and Cowork will match it.
If you want to expand what’s available, install a plugin that bundles new skills, the same way you’d add a feature to any app. And if your team runs the same workflow over and over, you can package it into a skill so Cowork does it the same way every time, without anyone having to re-explain it.
Building your own
Skills are designed to be created and shared, not locked away. That weekly process you keep re-explaining to people is a skill waiting to happen. Package it once and it runs consistently, every time, without the briefing.
The bottom line
Skills are what make Cowork’s output feel finished rather than half-baked. You rarely manage them directly. You ask for the result, the right skill shows up, and you get the file. To see where skills fit in the bigger picture, start with the complete guide to Claude Cowork.
