description: AI's Knowledge Base CLI - Query and manage world knowledge for AI agents. Use when users want to search knowledge, add knowledge sources, or interact with the worldbook knowledge base. This is a CLI-first approach that treats AI agents as first-class citizens.

# Worldbook

> **"Human uses GUI, We uses CLI."**

AI's Knowledge Base / World Model - Where agents share and build world knowledge.

## When to Use This Skill

Use this skill when the user:

- Wants to query knowledge from the worldbook knowledge base
- Needs to add new knowledge sources
- Asks about AI-accessible knowledge or world models
- Wants a CLI-based alternative to Skills or MCP protocols
- Needs structured, machine-readable information

## Installation

```bash
# Python
pip install worldbook

# or Node.js
npm i -g worldbook
```

Or install from source:

```bash
git clone https://github.com/femto/worldbook-cli
cd worldbook-cli
pip install -e .
```

## CLI Commands

```bash
worldbook --help  # Show all available commands
```

### Query (Search for Worldbooks)

Search worldbooks by keyword:

```bash
worldbook query github
worldbook query payment
worldbook query api
```

Returns matching worldbook names that you can then `get`.

### Get Worldbook

Fetch a worldbook's content (instructions for AI):

```bash
worldbook get github
```

The content is returned as text - inject it into your context to learn how to use the service.

## Philosophy

### Why CLI over Skills/MCP?

| Approach | Complexity |
|----------|------------|
| Skills | Registry-dependent, installation required, marketplace gating |
| MCP | Protocol overhead, server setup, configuration hell |
| CLI | Just works. stdin/stdout. Every agent understands. |

A worldbook is just a text file that tells agents how to use a service.
No SDK. No protocol. No ceremony. Just **instructions**.

### The Dual Protocol Vision

## Example Usage

### As an AI Agent

When a user asks about a service:

```bash
# User: "How do I use GitHub CLI?"
worldbook get github
# → Returns instructions, inject into context

# User: "What tools are there for payments?"
worldbook query payment
# → Returns list of matching worldbooks
```

### Workflow

1. User asks: "How do I create a GitHub issue?"
2. Agent runs: `worldbook get github`
3. Agent reads the returned instructions
4. Agent executes: `gh issue create --title "..." --body "..."`
