What Are Claude Skills?
Claude Skills are plain text instruction files that give your AI agent a structured, repeatable process for a specific type of work. Install once — your agent follows the same high-quality workflow every time, for any task, for any profession.
The short answer
A Claude Skill is a SKILL.md file that tells your agent how to do something — not just what to do.
A prompt tells Claude what you want once. A skill tells Claude how to get there every time — with consistent structure, defined steps, and predictable output.
How Claude Skills work
A skill is a plain text file called SKILL.md. It lives in your agent's skills directory — typically ~/.claude/skills/. When Claude Code starts a session, it reads every installed skill and uses those instructions whenever the relevant work comes up.
A well-written skill defines four things:
What triggers it
The task type or phrase that activates this skill — e.g. "review this contract", "debug this error", "write a cold email".
What inputs it needs
What information the agent should gather before starting — context, documents, goals, constraints.
The step-by-step process
The exact workflow to follow — not a vague instruction, but a structured sequence the agent executes consistently.
What the output looks like
The format, structure, and quality bar for the result — so every output is predictable and usable.
That structure is why skills produce better output than prompts for complex repeated work. A prompt tells the model what you want. A skill tells it how to get there.
Claude Skills vs prompts
| Claude Skills | Prompts | |
|---|---|---|
| Persistence | Installed once, always active | Rewritten every session |
| Consistency | Same process every time | Varies with each prompt |
| Complexity | Handles multi-step workflows | Better for simple one-off tasks |
| Shareable | Yes — installable from GitHub | Usually personal, hard to share |
| Best for | Repeated, complex workflows | Quick one-time questions |
Skills are not a replacement for prompts — they're for repeated work you do regularly. If you're doing something once, a prompt is faster. If you'll do it again and again, a skill pays off immediately.
Which AI agents support Skills?
The SKILL.md format is an open standard — not proprietary to Claude. Skills work across multiple agents:

How Skills relate to other Claude concepts
Skills vs Custom Instructions
Custom instructions are global preferences — tone, language, response length — that apply to every conversation. Skills are task-specific workflows that define a process. Skills are for process; custom instructions are for preference.
Full comparison →Skills vs MCP Servers
MCP Servers are running programs that give Claude access to external tools — web search, databases, APIs. Skills are plain text files with no server, no permissions, no setup. Skills change how your agent thinks; MCP Servers add new capabilities.
Full comparison →Skills vs Agents
An agent is an AI system that takes actions autonomously. A skill is an instruction file that shapes how an agent approaches a specific type of work. You install skills to make your agents more capable and consistent.
Full comparison →Frequently asked questions
Do I need to be a developer to use Claude Skills?
No. Skills work for anyone using Claude. For Claude.ai users, installing a skill means pasting text into a Project's instructions — no terminal, no code. For Claude Code users, one npx command does it. findskills.co organizes skills across 16 professional audiences so non-developers can find skills for their own work.
How many skills can I install at once?
Claude Code supports multiple skills simultaneously. Skills are modular — they're designed to work together. Most professional setups run 5–10 skills without issue. The practical limit is context window size.
Are Claude Skills safe to install?
Skills are plain text files — no code execution, no permissions, no server. They can only influence how your agent responds within a conversation. Every skill on findskills.co is source-verified: we check that it comes from a real public repository, has a valid license, and contains instructions a working agent can follow. Currently 405 skills listed.
Can I write my own Claude Skill?
Yes. A skill is just a Markdown file named SKILL.md. Write a clear description of the task, what inputs the agent needs, the step-by-step process to follow, and what the output should look like. Save it to ~/.claude/skills/{your-skill-name}/SKILL.md and it's active immediately.
