ZO

A fast, minimal CLI for interacting with LLMs via OpenRouter.

Features

• Fuzzy model selection - /sonnet, /gpt4, /haiku
• File references - @file.txt to include, !file.txt to write, @!file.txt to read+write
• Interactive chat - Multi-turn conversations with --chat
• STDIN piping - cat code.rs | zo "review this"
• Streaming output - Syntax-highlighted markdown in real-time
• Custom models - Define aliases with system prompts

Quick Example

# Ask a question
zo "What is Rust?"

# Use a specific model
zo /sonnet "Explain async/await"

# Include files
zo "@main.rs Review this code"

#$ Pipeline
git diff | zo 'Summarize these changes'

# give read & write access to script.py
# (will show diff of changes and ask for approval)
zo 'Add type hints to @!script.py'

# give read access to src/*.rs and write-only access to ARCHITECTURE.md
zo '@src/*.rs document the architecture in !ARCHITECTURE.md'

# Chat mode (supports multiline with Alt-Enter, Ctrl-O, or Ctrl-J)
zo --chat /sonnet 'Explain async/await'
> Show me a practical example
> How does it compare to threads?
> exit
