Memory is how agents remember context to decide what to do next. ## Types of Memory | Type | Description | |-------------------|-----------------------------------------------------------------------------| | Short-term | Stored in the current LLM prompt | | Long-term | Indexed and retrieved as needed, often from vector stores | | Scratchpad | Temporary summaries or notes used during transitions | | Shared memory | Global state accessible to multiple agents | ## Implementing Memory Memory can be maintained using: - Prompt engineering with structured history - External stores like Redis or Pinecone - MCP-based memory tools
