# Cersei

The complete Rust SDK for building coding agents.

Cersei gives you every building block of a production coding agent — tool execution, LLM streaming, sub-agent orchestration, persistent memory, skills, MCP integration — as composable library functions. Build a Claude Code replacement, embed an agent in your app, or create something entirely new.

```rust
use cersei::prelude::*;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let output = Agent::builder()
        .provider(Anthropic::from_env()?)
        .tools(cersei::tools::coding())
        .permission_policy(AllowAll)
        .run_with("Fix the failing tests in src/")
        .await?;

    println!("{}", output.text());
    Ok(())
}
```
