Encapsulation & Method Resolution Order (MRO)

class AgentContext:
    def __init__(self, session_id: str, memory_limit: int = 100):
        self._session_id = session_id
        self._memory_limit = memory_limit
        self._history = []

    def record(self, role: str, content: str) -> None:
        self._history.append({"role": role, "content": content})
        if len(self._history) > self._memory_limit:
            self._history.pop(0)

    def __repr__(self) -> str:
        return f"<AgentContext id={self._session_id} turns={len(self._history)}>"

Dunder methods like __init__, __repr__, and __len__ integrate your custom classes natively with Python built-ins, enabling clean, robust abstraction layers.
