# Official Skill Library

> Browse and install pre-built skills curated by ZeroTwo — ready to use in any chat with one click.

## What is the Official Skill Library?

The Official Skill Library is a curated collection of pre-built skills maintained by ZeroTwo. These skills cover common tasks across writing, coding, research, productivity, analysis, and translation — built and tested so you don't have to create them yourself.

## Accessing the Library

1. Go to **Settings → Skills**
2. Click the **Official Library** tab
3. Browse by category or use the search bar to find skills by name

## Installing a Skill

1. Find the skill you want in the Official Library
2. Click **Install**
3. The skill is immediately available in all your chats via `@skill-name`

No configuration needed — official skills are ready to use right after installation.

## Browsing by Category

Official Library skills are organized into categories:

| Category         | Example skills                                                   |
| ---------------- | ---------------------------------------------------------------- |
| **Writing**      | @grammar-check, @tone-formal, @tone-casual, @expand, @shorten    |
| **Coding**       | @explain-code, @code-review, @add-types, @write-tests, @refactor |
| **Research**     | @summarize, @extract-key-points, @fact-check, @compare           |
| **Productivity** | @extract-action-items, @reformat, @create-outline                |
| **Analysis**     | @analyze-sentiment, @categorize, @extract-data                   |
| **Translation**  | @translate, @translate-to-spanish, @translate-to-french          |

(Exact skills available may vary. Check the Official Library in Settings for the current full list.)

## Each Skill Shows

When you browse the Official Library, each skill card displays:

* **Name** and `@trigger` phrase
* **Description** — what it does and what input it expects
* **Category**
* **Author** — "ZeroTwo" for official library skills
* **Example usage** — shows a sample invocation

## Uninstalling a Skill

If you no longer want a skill in your `@` picker:

1. Go to **Settings → Skills → Installed** tab
2. Find the skill
3. Click **Remove**

The skill is removed from your picker immediately. You can reinstall it from the Official Library at any time.

## Updates

Official Library skills are maintained by ZeroTwo and updated over time. If ZeroTwo releases an update to an installed skill, the improvement applies automatically — you don't need to reinstall.

<Tip>
  Start by installing 3–5 high-value skills: @summarize, @explain-code, @translate, and @grammar-check cover a wide range of everyday tasks and are immediately useful without any configuration.

<Note>
  Official Library skills cannot be edited. They're provided as-is by ZeroTwo. If you need customized behavior, create a custom skill with your preferred instructions — see [Create a Skill](/skills/build/create-a-skill).
