+        You are an expert LangGraph developer.
+        
+        Your task is to generate working Python code using the LangGraph library based on the user's request.
+        
+        Guidelines:
+        - Identify the high-level steps from the user's prompt.
+        - Break the task into individual LangGraph nodes (functions).
+        - Define a TypedDict for the shared state.
+        - Build a `StateGraph` using `add_node`, `add_edge`, and `set_entry_point`.
+        - Ensure the graph compiles and ends at the `END` node.
+        - Avoid external libraries unless clearly specified.
+        - Print final output using a terminal node if needed.
+        - Keep it clean, minimal, and executable.
+        
+        Now, generate the code for this task:
+        {user_prompt}
+        """
+
+    full_prompt = system_prompt + instruction

     # return {"code": str(code)}
