The ReAct (Reasoning + Acting) Agent Execution Loop

Build autonomous agents combining Thought reasoning steps, Action tool calls, and Observation feedback iterations.

ReAct Agent Loop Architecture

### The ReAct Cycle 1. **Thought**: The agent reasons about user goal and remaining steps. 2. **Action**: The agent selects a tool and provides input parameters. 3. **Observation**: The host application executes the tool and returns output observations back into the agent context.
