Creating a Basic Memory Agent

Now, let's create a simple agent with memory capabilities. We'll start with the basics and add more advanced features in the following steps.

Create or update your src/mastra/agents/index.ts file:

import { Agent } from "@mastra/core/agent";
import { Memory } from "@mastra/memory";
import { LibSQLStore } from "@mastra/libsql";
import { openai } from "@ai-sdk/openai";

// Create a basic memory instance
const memory = new Memory({
  storage: new LibSQLStore({
    id: "learning-memory-storage",
    url: "file:../../memory.db", // relative path from the `.mastra/output` directory
  }),
});

// Create an agent with memory
export const memoryAgent = new Agent({
  name: "MemoryAgent",
  instructions: `
    You are a helpful assistant with memory capabilities.
    You can remember previous conversations and user preferences.
    When a user shares information about themselves, acknowledge it and remember it for future reference.
    If asked about something mentioned earlier in the conversation, recall it accurately.
  `,
  model: openai("gpt-4o"), // You can use "gpt-3.5-turbo" if you prefer
  memory: memory,
});

In this example, we're creating a basic Memory instance without any special configuration. This default configuration will still provide your agent with the ability to remember previous messages in the conversation.

The key part is adding the memory property to your agent configuration, which connects the memory instance to your agent.
