use cc_sdk::{query, ClaudeCodeOptions};
use futures::StreamExt;

#[tokio::main]
async fn main() -> cc_sdk::Result<()> {
    let options = ClaudeCodeOptions::builder()
        .model("claude-opus-4-5-20251101")  // Latest Opus 4.5
        .auto_download_cli(true)             // Auto-download CLI
        .max_budget_usd(10.0)                // Budget limit
        .build();

    let mut stream = query("Hello, Claude!", Some(options)).await?;
    while let Some(msg) = stream.next().await {
        println!("{:?}", msg?);
    }
    Ok(())
