# Skill Marketplace

> Discover and install skill packs

Skills are modular knowledge packs that give AI Experts domain-specific capabilities. Through the Skill Marketplace, you can equip the Experts you use with additional abilities, or build your own global skill library.

## What Is a Skill

A skill is a set of structured instructions and knowledge that, once installed, gets injected into an AI Expert's context, granting it specific domain capabilities. For example:

* **Document Writing Skill**: Teaches an Expert specific document formatting standards
* **Code Review Skill**: Enables an Expert to review code following team coding standards
* **Data Analysis Skill**: Equips an Expert with a specific toolchain's data processing workflow
* **Operations Strategy Skill**: Gives an Expert domain-specific operational methodologies

<Tip>
  Skills are different from tools — tools are actions an Expert can perform (like search or image generation), while skills are knowledge and methodologies the Expert masters. They work best when used together.
</Tip>

## Browsing & Discovery

The Skill Marketplace organizes all available skills by category:

* Use the top category tabs for quick filtering
* Keyword search to locate specific skills
* Each skill card displays its name, description, and author information

## Skill Sources

The Skill Marketplace displays two types of skills:

| Source               | Description                                                   |
| -------------------- | ------------------------------------------------------------- |
| **Official Skills**  | Maintained by the Profy platform team with guaranteed quality |
| **Community Skills** | Contributed by the creator community, reviewed before listing |

Both types are installed and used the same way — the only difference is who maintains them.

## Installing Skills

Skills support two installation methods, corresponding to different scopes:

<AccordionGroup>
  <Accordion title="Install to Global Library">
    Installing a skill to your personal global library makes it **effective across all Experts you use**. Ideal for universal skills like writing standards or coding styles you want all Experts to follow.

    Path: Skill detail page → Click "Install to Global Library"
  </Accordion>

  <Accordion title="Install to a Specific Expert">
    Installing a skill to a specific Expert means **only that Expert gains this capability**. Ideal for domain-specific skills, like adding a code review skill only to your programming Expert.

    Path: Skill detail page → Click "Install to Expert" → Select target Expert
  </Accordion>
</AccordionGroup>

<Warning>
  Installing skills increases the Expert's context length. Too many skills may affect conversation quality — only install skills you truly need.
</Warning>

## Managing Installed Skills

### Viewing Your Global Library

In your personal settings, you can view and manage your global skill library, including enable/disable and uninstall operations.

### Viewing Expert Skills

In the Expert's Studio settings page, you can view all skills installed on that Expert and manage them.

## How Skills Take Effect

<Steps>
  <Step title="Install">
    Choose the installation method (global or specific Expert), and confirm the installation.
  </Step>

  <Step title="Inject">
    When the next conversation starts, installed skill knowledge is automatically injected into the Expert's context.
  </Step>

  <Step title="Activate">
    The Expert automatically applies the skill knowledge during conversation — no manual triggering needed.
  </Step>
</Steps>

<Note>
  A skill's effectiveness depends on the conversation model's capabilities. The same skill may perform differently across different models.
</Note>
