30 skills from Anthropic, and how to add them in Claude

What a skill is

Without skills, Claude guesses at the method every time you give it a task. A skill is the workflow written down in advance, with the questions and checks an experienced person in the field would ask.

Anthropic built these ones itself. They live in plugins: packages of skills for one field, such as marketing, design or small businesses. Once the package is added, Claude uses a skill when the task fits it. You can also call it up by name: type / in your message.

How skills fit together with projects and scheduled tasks is covered in the guide Chat and Cowork are now one Claude. What a skill is, and how to build your own, is in the guide Claude skills.

The ten

• 01 memory-management · Productivity

  Remembers your clients, projects, abbreviations and internal words, so you don't have to explain them again. It runs on its own and keeps them in a short file with what you use most, and a folder with the rest.

• 02 design-critique · Design

  Structured feedback on a design: usability, hierarchy and consistency. Give it a screenshot, a Figma link or a description, and tell it who it's for and how far along you are.

• 03 brand-review · Marketing

  Checks a text against your tone and your style guide and shows the corrections before and after, sorted by how serious they are. It also catches claims you can't back up.

• 04 draft-content · Marketing

  Drafts for posts, blog posts, newsletters and landing pages. It asks for the topic, the audience, your points and the length, and suggests headlines and subject lines.

• 05 email-sequence · Marketing

  A whole email sequence with copy and timing, for example your welcome flow. You get each email, when it goes out, and what happens when someone clicks or doesn't.

• 06 inbox-manager · Small Business

  Sorts your inbox into what needs you, what has a draft ready, and what's been handled. It writes the replies in your tone and finds the deadlines in long threads.

• 07 proposal-builder · Small Business

  A proposal from your meeting notes, a voice memo or a transcript. It uses your own templates, sets the price from what you've charged for similar jobs, and tells you when something is missing.

• 08 build-agent · Small Business

  Turns a task you repeat into a skill you can call by name or put on a schedule. At every step that sends, pays, publishes or deletes, it adds a stop, so nothing happens until you've approved it.

• 09 frontend-design · Frontend Design

  Direction, typography and deliberate choices when you build a page or an app. It starts from your field and your own material.

• 10 build-dashboard · Data

  A dashboard in one HTML file with your numbers, charts and filters. The file opens straight in the browser, with nothing to install.

How to add them

In Cowork, open the Cowork tab first. Plugins work on all paid plans, in chat and in Cowork. On Enterprise, an administrator may have limited which ones you can add.

Anthropic itself recommends installing plugins only from sources you trust, and you can read through its own on GitHub.

The four built-in skills

xlsx, docx, pptx and pdf are built in: Excel, Word, PowerPoint and PDF, on all plans. Turn on Code execution and file creation under Settings, Capabilities, and switch them on under Customize, Skills. Then Claude uses them on its own when you ask for a spreadsheet, a document, a presentation or a PDF.

Build on from there

Start with the plugin that fits the task that takes up most of your week.

Skills work best when Claude knows your business, so put your tone, your offers and your clients in one place. You use that foundation again for the next proposal, the next newsletter and the next post.

My own free skills are under Free guides. If skills and agents should be built for your business specifically, we set them up together in a 1:1 session.
