Simplified Command

yb "Write a quicksort in python"
# -> Same result as above

Interactive Chat Mode

yb --chat
# or
yb -c
|> Tell me about quantum computing
# -> [AI responds about quantum computing]
|> What are the practical applications?
# -> [AI responds with follow-up information]
|> exit

Process Piped Content

git diff | yb vibe "Generate a commit message"
# -> Added information to the README

yb vibe "What is this project about?" < README.md
# -> This project is about...

Generate Shell Command

yb vibe "How many lines of python code did I write?"
# -> find . -type f -name "*.py" | xargs wc -l
# -> [r]run, [e]edit, [y]copy, [c]chat, [q]quit (default: run): 

Advanced Model Selection

# Use think model for complex analysis
yb --think vibe "Analyze this complex algorithm and suggest optimizations"

# Use fast model for quick responses
yb --fast vibe "Translate 'Hello, World!' to French"

Shell Command Magic Integration

# List directory contents
yb vibe "$(ls) What files are in the current directory?"
# -> The current directory contains: file1.txt, file2.py, directory1/...

# Analyze Git status
yb vibe "$(git status) Which files should I commit first?"

# View code files
yb vibe "$(cat main.py) How can I improve this code?"

Smart Tool Discovery

# Viby will automatically discover and use relevant tools
yb vibe "What's the weather in San Francisco?"
# -> [Viby identifies and uses weather tools]
# -> The current weather in San Francisco is 68°F and partly cloudy...

# Embedding Model Management
# First download the embedding model (required once before using embedding features)
# Embed model configurable with yb --config
yb tools embed download

# Start the embedding server (required for tool discovery)
yb tools embed start

# Check embedding server status
yb tools embed status

# Update tool embeddings from configured MCP servers
yb tools embed update

# List available tools (udpate before listing)
yb tools list

# Stop the embedding server when not needed
yb tools embed stop

History Management

# View recent interactions
yb history list

# Search your history
yb history search "python"

# Export your interaction history
yb history export history.json

# View shell command history
yb history shell

# Clear history (with confirmation)
yb history clear

Automatically Use MCP Tools When Needed

yb vibe "What time is it now?"
# -> [AI uses time tool to get current time]
# -> "datetime": "2025-05-03T00:49:57+08:00"

Keyboard Shortcuts

Viby provides a convenient keyboard shortcut (Ctrl+Q) that allows you to quickly use Viby with the current command line content:

# Install the keyboard shortcuts (auto-detects your shell)
yb shortcuts

# After installation, type any command and press Ctrl+Q
help me analyze my readme file  # Now press Ctrl+Q
# -> This transforms into: yb vibe help me analyze my readme file
# -> [AI analyzes and responds to question]

Supported shells:

• Bash
• Zsh
• Fish

After installing shortcuts, you'll need to reload your shell configuration (source ~/.bashrc, source ~/.zshrc, or equivalent) or restart your terminal for the shortcuts to take effect.

Command Structure

Viby uses a simple command structure:

yb [OPTIONS] [COMMAND] [ARGS]...

Main commands:

• yb [prompt] - Ask a question (alias for yb vibe "your question"; recommended)
• yb vibe "your question" - Ask a question (default command for questions)
• yb --chat or yb -c - Start interactive chat mode
• yb --think vibe "complex question" - Use the think model for deeper analysis
• yb --fast vibe "simple question" - Use the fast model for quick responses
• yb history - Manage interaction history
• yb tools - Manage tool-related commands
• yb shortcuts - Install keyboard shortcuts

Use yb --help to see all available commands and options.

Configuration

Viby reads configuration from ~/.config/viby/config.yaml. You can set the model, parameters, and MCP options here.

Interactive Configuration

Use the configuration wizard to set up your preferences:

yb --config

This allows you to configure:

• API endpoint and key
• Model
• Temperature and token settings
• MCP tools enablement
• Interface language
• Embedding model settings

MCP Server Configuration

Viby supports Model Context Protocol (MCP) servers for extended capabilities. MCP configurations are stored in ~/.config/viby/mcp_servers.json.
