Building a Complete Memory-Enhanced Agent

In this final step, we'll bring together all the memory features we've explored to create a complete memory-enhanced agent. We'll also create a practical example that demonstrates how these features work together.

Combining All Memory Features

Let's create a comprehensive agent that utilizes conversation history, semantic recall, and working memory:

typescript

// src/mastra/agents/memory-agent.ts
import { Agent } from '@mastra/core/agent'
import { Memory } from '@mastra/memory'
import { LibSQLStore, LibSQLVector } from '@mastra/libsql'

// Create a comprehensive memory configuration
const memory = new Memory({
  storage: new LibSQLStore({
    id: 'learning-memory-storage',
    url: 'file:../../memory.db', // relative path from the `.mastra/output` directory
  }),
  vector: new LibSQLVector({
    url: 'file:../../vector.db', // relative path from the `.mastra/output` directory
  }),
  embedder: 'openai/text-embedding-3-small',
  options: {
    // Conversation history configuration
    lastMessages: 20, // Include the last 20 messages in the context

    // Semantic recall configuration
    semanticRecall: {
      topK: 3, // Retrieve 3 most similar messages
      messageRange: {
        before: 2, // Include 2 messages before each match
        after: 1, // Include 1 message after each match
      },
    },

    // Working memory configuration
    workingMemory: {
      enabled: true,
      template: `

    },
  },
})

This comprehensive memory configuration combines all three memory features we've explored:

Conversation history with the lastMessages option
Semantic recall with the semanticRecall option
Working memory with the workingMemory option

Each feature serves a different purpose in enhancing your agent's memory capabilities, and together they create a memory system that maintains context across conversations and provides personalized responses.
