"""
Common utilities and base classes for agents.

This module provides a unified namespace for commonly used base classes and utilities,
allowing simplified imports like:
    from src.agents.common import BaseAgent, BaseContext, BaseState

For other specific functions, use the original import style:
    from src.agents.common.tools import query_knowledge_graph
    from src.services.mcp_service import MCP_SERVERS
