brainwires

Unified facade crate for the Brainwires Agent Framework — build any AI application in Rust.

Overview

brainwires is the single entry point for the entire framework. It re-exports 17 sub-crates as feature-gated modules and provides a prelude that pulls in the most commonly needed types. Add one dependency, enable the features you need, and you're ready to go.

brainwires-core (messages, tools, providers, tasks, errors) is always available — no feature flag required. Everything else is opt-in.

Quick Start

Add to your Cargo.toml:

[dependencies]
brainwires = "0.1"  # default features: tools + agents

Then import via the prelude:

use brainwires::prelude::*;

let messages = vec![
    Message::system("You are a helpful assistant."),
    Message::user("Hello!"),
];

let options = ChatOptions::deterministic(1024);
let response = provider.chat(&messages, None, &options).await?;

Features

Convenience Features

Usage Examples

Agent Workflow

[dependencies]
brainwires = { version = "0.1", features = ["agent-full"] }

use brainwires::prelude::*;

// Set up the agent runtime
let hub = CommunicationHub::new();
let lock_manager = FileLockManager::new();
let runtime = AgentRuntime::new(hub, lock_manager);

// Define validation checks
let validation = ValidationConfig {
    checks: vec![ValidationCheck::FileExistence, ValidationCheck::Syntax],
    working_directory: "/my/project".into(),
    max_retries: 3,
    enabled: true,
    working_set_files: vec![],
};

MCP Server with RAG

[dependencies]
brainwires = { version = "0.1", features = ["rag", "mcp-server"] }

use brainwires::rag::mcp_server::RagMcpServer;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    tracing_subscriber::fmt::init();
    RagMcpServer::serve_stdio().await?;
    Ok(())
}

RAG Pipeline

[dependencies]
brainwires = { version = "0.1", features = ["rag"] }

use brainwires::rag::RagClient;

let client = RagClient::new(None).await?;
client.index("/path/to/project", None, None).await?;

let results = client.query("authentication logic", 10, 0.7).await?;
for result in results {
    println!("{}: {:.2}", result.file_path, result.score);
}

Learning System

[dependencies]
brainwires = { version = "0.1", features = ["learning"] }

use brainwires::prelude::*;

let cache = BehavioralKnowledgeCache::new();
let truth = BehavioralTruth::new("always_use_async", TruthCategory::Pattern);
cache.store(truth);
