1//! # Volter Harness
2//!
3//! A lightweight, fully-customizable AI coding-agent SDK in Rust.
4//!
5//! `supercode` is a native agent loop — it talks directly to any model through
6//! [OpenRouter](https://openrouter.ai) (or any other OpenAI-compatible endpoint),
7//! drives a configurable set of tools, and is designed to be a superset of what
8//! tools like Claude Code and Codex can do: every prompt, every tool description,
9//! and every tool's on/off state is yours to control.
10//!
11//! ## Quick start
12//!
13//! ```no_run
14//! use supercode_harness::{Agent, Config};
15//!
16//! # async fn run() -> supercode_harness::Result<()> {
17//! // Reads OPENROUTER_API_KEY from the environment by default.
18//! let config = Config::builder()
19//!     .model("anthropic/claude-opus-4-8")
20//!     .system_prompt("You are a terse, expert pair programmer.")
21//!     .build();
22//!
23//! let mut agent = Agent::new(config)?;
24//! let reply = agent.send("List the files in the current directory.").await?;
25//! println!("{reply}");
26//! # Ok(())
27//! # }
28//! ```
29//!
30//! ## Design
31//!
32//! - [`Config`] — the single knob box: model, endpoint, credentials, sampling,
33//!   the system prompt, and per-tool overrides (enable/disable + custom
34//!   descriptions).
35//! - [`Provider`] — the model transport. [`OpenAiProvider`] speaks the
36//!   OpenAI chat-completions wire format and defaults to OpenRouter, so it
37//!   reaches Claude, GPT, Gemini, Llama, and anything else OpenRouter exposes.
38//! - [`Tool`] / [`ToolRegistry`] — the capability surface. Built-ins cover
39//!   file read/write/edit, directory listing, glob, content search, and shell
40//!   execution. Register your own to extend it.
41//! - [`Agent`] — the loop that ties it together: it streams a turn, runs any
42//!   tool calls the model requests, feeds results back, and repeats until the
43//!   model produces a final answer.
