What Is a Skill? Understand It in 3 Minutes and Install Your First
Lots of people install Skills without being able to explain them · this guide plainly explains what Skills are, how they differ from Prompts and MCP, and how to install and use them
Free · works across Claude Code, Codex and Cursor · includes a one-command install prompt
"I installed a pile of Skills, but cannot explain what one actually is"
"A lot of people still do not understand what Skills are or how they differ from MCP and Agents, so let us sort that out."
— Xiaohongshu · how should we understand Skills? (translated from Chinese)
"Every time you ask AI to do the same kind of work, you have to restate the background, requirements, format and pitfalls. Do it ten times, brief it ten times."
— Xiaohongshu · skill-creator explained (translated from Chinese)
"Working with AI used to be like hiring a new assistant: every time you had to teach it step by step — what comes first, what comes next, what format to use — until you wanted to quit."
— Xiaohongshu · a plain-language guide to what Skills are (translated from Chinese)
These real voices scattered across Xiaohongshu, Zhihu and Jike add up to everyday life for people who have heard of Skills but do not know what they are. Skills are not too complicated — nobody has explained them plainly.

Install deep-skill-finder once, let your Agent find Skills itself
You do not need to understand every Skill first — once deep-skill-finder is installed, your Agent searches the 50,000+ Skill library on MEYO whenever it takes on a task and recommends the capabilities that match. You just say what you want done and leave the matching to the Agent.
Copy the command → paste it to Claude Code, Codex, Cursor or WorkBuddy · your Agent installs it automatically:
Please install the deep-skill-finder skill: download the archive from https://www.meyo.life/skill-finder?ref=pseo_what-is-skill, unpack it into the local skill directory and enable it.
Or read on for the Skill concepts. To learn more about deep-skill-finder →

3 Core Ideas Behind Skills · Explained at Once
01
What Is a Skill? The One-Sentence Version
When you asked AI to work, you had to restate the background, requirements, format and pitfalls every time.A Skill writes down how this kind of job should be done and gives that instruction set to the AI once; afterwards, it recognises the job and follows it without you repeating yourself.
-
✓
Write weekly reports, review code, format documents — configure a Skill once, then just call its name.
-
✓
It packages expert steps, pitfalls and standard formats, turning AI into a seasoned teammate.
-
✓
Agent-neutral · installable in Claude Code, Codex and Cursor
02
Skill vs Prompt vs MCP · Do Not Mix Them Up
They are not mutually exclusive; they sit at different layers
Prompt is text you send manually each time, discarded after one use.Skill packages those instructions as a reusable capability, written once and reused forever.MCP Server is an interface protocol for external tools, such as GitHub APIs and databases. Simply put:MCP is the socket, Skill is the appliance, and an appliance can plug into a socket。
-
✓
Prompt → one-off instruction · Skill → packaged reuse · MCP → external interface
-
✓
A Skill can contain Prompts and can call MCP Servers
-
✓
Skills have almost no learning curve · MCP needs development ability
03
How Do You Use One? Find → Install → Trigger
3 steps · from zero to one
First: find it. Browse the MEYO community, or install deep-skill-finder and let your Agent search.Second: install it. Copy the install command, paste it to your Agent, done in 30 seconds.Third: trigger it. State the task; once the Agent identifies the matching Skill it calls it automatically — no manual @ needed.

FAQ
Q: What is the difference between a Skill and a Prompt?
A: A Prompt is text you send to AI manually every time, discarded after one use. A Skill packages those instructions as a reusable capability; write it once and the Agent calls it automatically for similar tasks later.
Q: How do Skills relate to MCP Servers?
A: An MCP Server is an interface protocol for external tools such as GitHub APIs and databases. A Skill is a packaged AI capability that can contain Prompts, workflows and even call MCP Servers. Simply put:MCP is the socket, Skill is the appliance, and appliances can plug into sockets.
Q: I do not use Claude Code. Can I use Skills?
A: Yes. Skills are agent-neutral. Claude Code, Codex, Cursor and WorkBuddy all support them. Download the archive from meyo.life/skills and unpack it into your Agent’s Skill directory.
Q: I installed a Skill but the Agent does not use it. What now?
A: With deep-skill-finder installed, the Agent detects tasks and searches for matching Skills automatically. If it still does not use one: (1) make the task description more specific; (2) check whether the Skill description includes trigger conditions; (3) ask the Agent to diagnose the skill directory.
Q: Are Skills free?
A: Skills in the MEYO community are free and open source. A Skill itself consumes no credits; you only pay your normal API usage when the Agent runs it. They often use fewer tokens than a hand-written prompt.
