Claude Skills Marketplace

A Claude skills marketplace is a catalogue of downloadable .skill files that give Claude a defined role: its expertise, frameworks, tone, and the edge cases it handles. You download a file, paste its contents into project instructions or a system prompt, and Claude works as that specialist. KissMySkills lists 1,000+ skill files across 18 professional categories, and 20 of them are free.

What are Claude skill files?

A skill file is a structured configuration document that gives Claude deep expertise in a specific professional role. Instead of spending time crafting prompts and explaining context, you drop in a skill file and immediately get an AI assistant that thinks, responds, and delivers output like a real specialist in that field.

Think of it as hiring a consultant, analyst, or specialist - but instantly, and for the cost of a coffee. Load the Marketing Manager skill and Claude becomes a marketing strategist. Load the Legal Research skill and Claude becomes a paralegal. Load the CFO skill and Claude becomes your financial analyst.

Every profession, every role

Our catalogue covers the full spectrum of professional roles across industries: business and strategy, marketing and sales, technology, legal and finance, health and medical, creative and content, and operations - from CFOs and analysts to copywriters, developers, and HR managers.

Free vs paid Claude skills

Free Claude skill lists exist on GitHub and community sites, and most of them concentrate on developer and coding tasks. They ship the instruction file alone, so you find out what a skill produces by running it. Every skill here includes an example-output folder with a finished piece of work, so you judge the output before you rely on it - and twenty skills across the major categories are free to download and test.

Why skill files beat regular prompting

Generic prompting gives you generic results. Skill files give you specialist-quality output because they're built by professionals who actually work in those roles. Each skill contains years of professional knowledge, industry best practices, and real-world frameworks - and maintains consistency across every interaction, like a reliable team member who never has an off day.

How to install a Claude skill

1. Download the .skill file. It arrives as a ZIP.
2. Unzip it. You get SKILL.md and an example-output folder.
3. Open SKILL.md in any text editor and copy the contents.
4. In Claude, create a project and paste the text into project instructions. On the free plan, paste it at the start of a chat instead. Through the API, use the system prompt.
5. Start the conversation. Claude answers in that role from the first message.

The whole process takes under five minutes and requires no technical knowledge.

Which AI models work with these files

These skill files work with Claude, ChatGPT, Gemini, Copilot, and Perplexity. The content is plain Markdown, so any model that accepts custom instructions accepts a skill. In Claude use project instructions; in ChatGPT use a custom GPT; in Gemini use a Gem; in Copilot or Perplexity paste the text into the prompt. The wording is model-neutral, so the same file moves between tools without editing. No API key, plugin, browser extension, or subscription is required.
