"""Opus Orchestrator CLI.

Standalone CLI for running Opus book generation without OpenClaw.

Usage:
    opus --help
    opus generate --concept "Your story idea"
    opus serve --port 8000  # Start API server
    opus docs               # Show documentation
    
    # Or use as API client:
    opus --api-url http://localhost:8000 generate --concept "..."

Local mode (default): Runs generation locally using LangGraph/CrewAI
API mode: Sends requests to Opus API server

Usage:
    opus [GLOBAL_OPTIONS] <command> [OPTIONS]

Examples:
  # Local generation
  opus generate --concept "A robot dreams of love"
  
  # API client mode
  opus --api-url http://localhost:8000 generate --concept "..."
  opus --api-url https://opus-api.example.com generate --repo owner/repo
