Astra

A general-purpose agent framework in C#. The LLM reasons; the framework perceives, acts, and remembers.

Astra provides the core loop that turns any LLM into an iterative agent — call the model, execute tools, feed results back, repeat until done. It is designed to be specialized into domain-specific agents (coding, research, automation, and beyond) without changing the core.
