 #### messages_context_length (number)
 Specifies the number of previous messages to include as context for the AI agent. This enables the agent to maintain conversation history and remember past interactions. When set, the agent will have access to the specified number of previous messages from the conversation, allowing for more contextual and coherent responses across multiple interactions.
