The 13 Best Claude Skills, Ranked
1. frontend-design
frontend-design is the most installed Claude skill by a wide margin, at roughly 1,000,000 public installs according to skillscout.sh. It builds frontend interfaces with intentional aesthetic direction, which is a direct answer to the generic look most AI-generated UIs end up with.
It's built for developers working in Claude Code who want interfaces that look designed rather than assembled from defaults. It also helps product-minded marketers prototyping landing pages.
You can install it on its own with npx skills add anthropics/skills@frontend-design, or pull the full collection with npx skills add anthropics/skills. Source and instructions live in the anthropics/skills repo.
2. skill-creator
skill-creator sits at about 413,300 installs (skillscout.sh). It builds, tests and refines other skills, so it's the skill you reach for when the official list doesn't cover your workflow.
Developers use it to turn repeated Claude Code instructions into a reusable skill. Marketers can use it to package a recurring process, such as a campaign brief format, without writing the SKILL.md file from scratch.
Install it with npx skills add anthropics/skills@skill-creator. The Agent Skills docs explain how the resulting custom skills can be used in Claude Code, uploaded through the API or added in claude.ai settings.
3. pptx
pptx has around 241,000 public installs (skillscout.sh) and is one of the four pre-built document skills Anthropic ships. It lets Claude create and edit PowerPoint presentations.
It's the obvious pick for anyone producing decks on a schedule, from sales teams to marketers building quarterly reports.
According to the Agent Skills docs, pptx is available pre-built on claude.ai, the Claude API, Claude Platform on AWS and Microsoft Foundry. In Claude Code, add it with npx skills add anthropics/skills@pptx.
4. pdf
pdf comes in at about 215,600 installs (skillscout.sh). It reads and writes PDF files and handles merging, splitting, rotating, watermarking and encrypting them, along with text and table extraction and OCR for scanned pages.
If your work involves contracts, invoices or research papers, this is the skill that saves the most manual copying.
pdf is pre-built on claude.ai, the Claude API, Claude Platform on AWS and Microsoft Foundry (Agent Skills docs). For Claude Code, run npx skills add anthropics/skills@pdf.
5. docx
docx has roughly 205,800 installs (skillscout.sh). It lets Claude create and edit Word documents directly, so you get a file you can send instead of text you have to paste and reformat.
It fits marketers writing briefs and proposals and anyone in operations who lives in Word.
Like the other document skills, docx is pre-built on claude.ai, the Claude API, Claude Platform on AWS and Microsoft Foundry (Agent Skills docs). Claude Code users can add it with npx skills add anthropics/skills@docx.
6. xlsx
xlsx sits at about 186,700 installs (skillscout.sh). It reads, writes and edits Excel and other tabular files.
Analysts, finance teams and marketers pulling campaign data into spreadsheets get the most out of it.
xlsx is pre-built on claude.ai, the Claude API, Claude Platform on AWS and Microsoft Foundry (Agent Skills docs). In Claude Code, install it with npx skills add anthropics/skills@xlsx.
7. webapp-testing
webapp-testing has around 185,700 installs (skillscout.sh). It automates local web apps with Python Playwright, so Claude can click through and check the app you're building.
It's a developer skill first, most useful for Claude Code users who want Claude to verify its own frontend changes before handing them back.
Install it with npx skills add anthropics/skills@webapp-testing. Source is in the anthropics/skills repo.
8. mcp-builder
mcp-builder has roughly 130,600 installs (skillscout.sh). It's a guide for building MCP servers, which is how you connect Claude to outside tools and data.
It's for developers who need Claude to reach an internal API, database or SaaS product that doesn't have an MCP server yet.
Install it with npx skills add anthropics/skills@mcp-builder. The repo holds the full guide.
9. brand-guidelines
brand-guidelines applies brand colors and typography to the things Claude produces. The version in the anthropics/skills repo uses Anthropic's own brand, so most teams fork it and swap in their guidelines.
It's built for marketers and designers who keep fixing off-brand outputs. Install it with npx skills add anthropics/skills@brand-guidelines, then edit the files to match your brand.
10. doc-coauthoring
doc-coauthoring gives Claude a structured workflow for writing documents with you rather than for you. It suits anyone drafting long docs such as specs, proposals or playbooks.
Install it with npx skills add anthropics/skills@doc-coauthoring. Details are in the anthropics/skills repo.
11. internal-comms
internal-comms helps Claude write internal communications in a consistent company format. It fits team leads and ops people who send recurring updates.
Install it with npx skills add anthropics/skills@internal-comms. See the repo for what's included.
12. theme-factory
theme-factory applies visual themes to artifacts Claude creates, which keeps decks and documents visually consistent without restyling each one by hand. Marketers producing a lot of collateral will get the most out of it.
Install it with npx skills add anthropics/skills@theme-factory. Source is in the anthropics/skills repo.
13. canvas-design
canvas-design lets Claude create visual designs and export them as image and PDF files. It's useful for quick posters, social visuals and one-off graphics when a designer isn't available.
Install it with npx skills add anthropics/skills@canvas-design. The repo has the full skill.
Best Claude Skills for Marketing
If you work in marketing, start with pptx and docx for decks and briefs, then add brand-guidelines once you've replaced Anthropic's brand with your own. theme-factory and canvas-design cover visual output, and doc-coauthoring helps with long-form drafts like positioning docs. internal-comms is a good fit for anyone sending weekly updates to leadership.
These are the clearest Claude skills examples for marketing teams, but notice what they share. They handle format and consistency well. None of them knows how your best strategist would rewrite a weak headline or push back on a campaign angle. That judgment isn't in a template, which is the gap the section on Callstand below covers.
Best Claude Skills for Claude Code Developers
For Claude Code, frontend-design is the default first install, and the install data backs that up. Pair it with webapp-testing so Claude checks its UI work in a real browser through Playwright. mcp-builder is the one to grab when Claude needs to talk to a system it can't reach yet, and skill-creator turns your own repeated instructions into skills you can reuse across projects.
The anthropics/skills repo also includes claude-api, web-artifacts-builder, algorithmic-art, slack-gif-creator and a template-skill folder you can copy as a starting point.
How to Install Claude Skills
Claude Code: The anthropics/skills README documents registering the repo as a plugin marketplace with /plugin marketplace add anthropics/skills, then installing the document-skills or example-skills plugin (for example /plugin install document-skills@anthropic-agent-skills). The open skills CLI listed on skillscout.sh also installs the full collection with npx skills add anthropics/skills, or a single skill by appending its name, such as npx skills add anthropics/skills@frontend-design.
claude.ai: The pre-built pptx, xlsx, docx and pdf skills are available on claude.ai. Custom skills can be added in claude.ai settings (Agent Skills docs).
Claude API: Custom skills can be uploaded through the API. Using skills there requires the code execution tool, and you pass the skill_id in the container parameter (Agent Skills docs). The pre-built document skills are also available on the Claude API, Claude Platform on AWS and Microsoft Foundry.
Claude Enterprise: Admins can turn on skill content scanning for custom skills uploaded in claude.ai and Claude Cowork, according to the same docs.
When a Claude Skill Isn't Enough: Callstand
Picture a content lead who installs brand-guidelines, swaps in the company's colors and fonts, and adds a page of tone notes. Claude now produces on-brand drafts. But when a junior marketer asks Claude whether a draft is actually good, the skill can't answer the way the content lead would. It knows the rules that were written down. It doesn't know that this content lead always cuts the second paragraph of an intro, or that a certain kind of headline never works for this audience.
That's the limit of a static skill. A skill is a SKILL.md folder you write once and maintain by hand, and it lives wherever you installed it. When your thinking changes, someone has to edit the files and reinstall them.
A Callstand stores the content lead's know-how as something agents call. Claude, ChatGPT and other MCP clients can call it through MCP or an API to strategize, draft or critique in that person's style. The junior marketer gets the critique the content lead would have given, inside the tool they already use. The content lead can share it with the team, or price it per call and let people outside the company use it too.
Skills are great for repeatable formats. If the value is in someone's judgment, build a Callstand.
Claude Skills FAQ
What are the best Claude skills in 2026?
By public installs, the top Claude skills are frontend-design, skill-creator, pptx, pdf and docx (skillscout.sh). The right pick depends on your work. Developers usually start with frontend-design, while office and marketing users get more from the document skills.
Which Claude skill is the most popular?
frontend-design leads with roughly 1,000,000 public installs as of October 2026, more than double the next skill, skill-creator, at about 413,300 (skillscout.sh).
What is the difference between Claude skills and MCP?
A Claude skill is a folder of instructions and resources that Claude loads when a task calls for it. MCP is a protocol for connecting Claude to external tools and data. You can use both together, and the mcp-builder skill exists to help you build MCP servers.
Do Claude skills work in the API?
Yes. The Agent Skills docs state that skills on the API need the code execution tool, with the skill_id passed in the container parameter. Custom skills can be uploaded through the API, and the pre-built document skills are available there too.
How do I install Claude skills in Claude Code?
Use the plugin marketplace route from the anthropics/skills README (/plugin marketplace add anthropics/skills), or run npx skills add anthropics/skills with the open skills CLI for the full official set and npx skills add anthropics/skills@skill-name for one skill. Custom skills can also be created directly in Claude Code.
How do I create a Claude skill?
A skill is a folder with a SKILL.md file whose frontmatter gives the skill a name and a description, followed by the instructions and any scripts or resources it needs (Agent Skills docs). The skill-creator skill can draft, test and refine one for you.
What's the difference between Claude Projects and skills?
A Project is a workspace in claude.ai with its own files and instructions that apply to the chats inside it. A skill is a packaged capability Claude loads only when a task calls for it, in any conversation where it's installed. Use a Project for context about one body of work and a skill for a repeatable task.
What are good Claude skills examples for marketing?
pptx and docx handle decks and briefs, brand-guidelines keeps outputs on brand once you add your own guidelines, and canvas-design covers quick visuals. All of them are in the anthropics/skills repo.
Does installing many Claude skills slow Claude down?
The docs describe progressive disclosure: Claude loads only each skill's name and description at first and reads the full instructions when a skill is relevant (Agent Skills docs). That keeps unused skills from filling up the context.
Are custom Claude skills safe to use at work?
Treat a custom skill like any code you didn't write and review it before use. On Claude Enterprise, admins can turn on skill content scanning for custom skills uploaded in claude.ai and Claude Cowork.
