🤖

Agent-first API

Define agents with a simple fluent interface or class-based syntax. The SDK handles the agentic loop, tool execution, and retry logic automatically.

🔧

Composable Tools

Build custom tools with a typed schema builder and plug them into any agent. Built-in WebFetch tool included out of the box.

🔀

Multi-agent Patterns

Prompt chaining, routing, parallelization, orchestrator-workers, and evaluator-optimizer — all the patterns from Anthropic's building-effective-agents playbook.

📐

Structured Output

Define a JSON Schema with a fluent builder and get strongly typed, validated structured data back from any model.

🔌

Provider-agnostic

Swap AI providers by changing one line. Ships with an OpenRouter adapter. Implement the two-method AIProvider interface to add any model API.

🌊

Streaming

First-class async generator streaming with tool calls handled transparently mid-stream.
