AgentKitten: Swift package for provider-agnostic AI agents

AgentKitten is an open-source Swift package that enables developers to build provider-agnostic AI agents, allowing seamless integration with multiple LLM backends (like OpenAI and Anthropic) through a unified interface. It is designed for Swift developers building AI-powered applications, offering a lightweight, type-safe framework that simplifies agent orchestration and tool use. Its key appeal lies in decoupling agent logic from specific AI providers, making it easy to swap models or scale without rewriting code.
