Agex is a Python-native agentic framework that allows agents to interact directly with existing libraries and return complex Python objects without needing tool abstractions or JSON serialization. It enables agents to dynamically create and modify functions using a sandboxed AST environment, promoting seamless integration and persistence of agent state across tasks. The framework emphasizes interoperability, observability, and multi-agent orchestration, making it particularly useful for developers looking to enhance their coding capabilities with AI-driven assistance.
