ReAct Agent Simulator

Concept from "Agentic Reasoning" Survey (Pages 15, 18)

ReAct (Reasoning + Acting) interleaves Chain-of-Thought reasoning with tool-use actions:

• Thought: The agent reasons about what to do next
• Action: The agent invokes a tool (search, calculate, lookup)
• Observation: The agent receives the tool's output
• Loop: Repeat until the task is solved

"The foundation of in-context agentic reasoning lies in augmenting Chain-of-Thought with the ability to take action."
