1  """agent2 — RESTai agent runtime that does NOT depend on llamaindex.
 2  
 3  Pure-Python ReAct-style agent loop built on top of raw provider SDKs
 4  (`anthropic`, `openai`). Adapted from the standalone_agent reference and
 5  wired to RESTai's existing tool registry, LLM database rows, guards, and
