I downloaded an updated skill package from Yavira.

## Documentation

### 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.

### Why CLI over Skills/MCP?

ApproachComplexitySkillsRegistry-dependent, installation required, marketplace gatingMCPProtocol overhead, server setup, configuration hellCLIJust 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.

### 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

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