class Agent:
    """Agent class for interacting with Auto-GPT.

    Attributes:
        ai_name: The name of the agent.
        memory: The memory object to use.
        full_message_history: The full message history.
        next_action_count: The number of actions to execute.
        system_prompt: The system prompt is the initial prompt that defines everything the AI needs to know to achieve its task successfully.
        Currently, the dynamic and customizable information in the system prompt are ai_name, description and goals.

        triggering_prompt: The last sentence the AI will see before answering. For Auto-GPT, this prompt is:
            Determine which next command to use, and respond using the format specified above:
            The triggering prompt is not part of the system prompt because between the system prompt and the triggering
            prompt we have contextual information that can distract the AI and make it forget that its goal is to find the next task to achieve.
            SYSTEM PROMPT
            CONTEXTUAL INFORMATION (memory, previous conversations, anything relevant)
            TRIGGERING PROMPT

        The triggering prompt reminds the AI about its short term meta task (defining the next task)
