Crate radkit 

radkit

A Rust SDK for building AI agents that run on native and WASM targets.

Overview

radkit provides:

• Agent Runtime: Execute agents with skills and tool calling
• LLM Integration: Unified interface for multiple LLM providers
• Tool System: Extensible tool/function calling framework
• Cross-Platform: Native (tokio) and WASM (single-threaded) support
• Type Safety: Strong types with comprehensive error handling

Quick Start

use radkit::agent::Agent;
use radkit::runtime::DefaultRuntime;
use radkit::tools::{FunctionTool, ToolResult};
use serde_json::json;

// Create a simple agent
let agent = Agent::builder()
    .with_id("my-agent")
    .with_name("My Agent")
    .build();

// Define tools
let tool = FunctionTool::new(
    "get_weather",
    "Get weather for a location",
    |args, _ctx| Box::pin(async move {
        ToolResult::success(json!({"temp": 72}))
    })
);

// Create a runtime
let runtime = DefaultRuntime::new();

Feature Flags

radkit uses feature flags to control optional dependencies:

• (Features will be documented as they’re added)

Platform Support

• Native (Linux, macOS, Windows): Full async runtime with tokio
• WASM (wasm32-wasi, wasm32-unknown-unknown): Single-threaded execution

Architecture

• agent: Agent definitions and builders
• tools: Tool system for function calling
• runtime: Runtime services and execution
• errors: Typed error handling
• compat: Cross-platform compatibility layer
