worldbook（worldbook 命令行）

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

# Python
pip install worldbook

# or Node.js
npm i -g worldbook

Or install from source:

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

CLI Commands

worldbook --help  # Show all available commands

Query (Search for Worldbooks)

Search worldbooks by keyword:

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):

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?

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:

# 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 "..."
