## Description

This project is a software development kit and framework for building AI agent orchestration, session management, and tool integration systems. It provides a backend infrastructure for hosting remote AI sessions and coordinating multi-agent workflows using large language models.

The SDK enables the definition of specialized agents and the orchestration of complex tasks through parallel workstreams. It distinguishes itself by offering a multi-tenant backend capable of horizontal scaling and a headless server runtime that separates session execution from the client interface.

The system covers a broad set of capabilities including stateful session persistence, provider-agnostic model integration, and fine-grained control over tool execution via interception hooks. It also manages identity through OAuth flows and managed identities, while providing observability through distributed trace instrumentation and resource usage tracking.
