🛠️ Tool-Calling AI Agent

A LangGraph-inspired Tool-Calling AI Agent with 3 tools:

• —🔢 Calculator — Safe math expression evaluation
• —🌐 Web Search — Knowledge base lookup
• —📁 File Reader — Read text files

Each response shows the full reasoning trace: Thought → Tool Call → Tool Result → Final Answer

Usage

Just type your question! Examples:

• —What is 2 + 2?
• —Calculate the area of a circle with radius 7
• —Tell me about LangGraph
• —Read app.py

Architecture

User Query → Intent Detection → Tool Selection → Execution → Response
     │            │                   │              │           │
     └──── Thought ──── Tool Call ────┴── Tool Result ─┴─ Final ──┘

Built with Python and Gradio. No external LLM API needed — the agent uses deterministic intent routing.
