Overview

Decorator-based interface for seamless LLM integration

✓ Decorator-based syntax reduces boilerplate code for LLM function calls significantly
✓ Seamless integration with multiple LLM providers via unified interface
✓ Type hints enable IDE autocomplete and catch errors before runtime
✓ Lightweight framework focused on core functionality without bloat

✗ Limited documentation and smaller community compared to established frameworks like LangChain
✗ Best suited for well-defined tasks; struggles with ambiguous, open-ended agent goals
