Build a GPT-5 Reasoning Agent

Develop an AI agent leveraging GPT-5's advanced reasoning and tool use capabilities to solve complex, multi-step problems. The agent should demonstrate its ability to break down complex tasks, utilize external tools (e.g., calculators, search engines), and justify its reasoning process. Focus on creating a robust and adaptable agent capable of handling unforeseen challenges within a defined problem domain.
