 In multi-turn and multiple sessions, an Agent often needs to "remember what happened before": such as user preferences, historical conclusions, previously confirmed facts, etc. Blades provides Memory capabilities for storing and retrieving information across multiple Sessions, allowing the Agent to "recall" context in new conversations, thereby reducing repetitive questioning and improving consistency.

 - Session / State addresses the organization and temporary data management "within the current conversation thread" (the tutorial is covered in the previous chapter).
 - Memory is oriented towards "historical information across multiple sessions," which can be retrieved to assist in current responses. It can be understood as the Agent's "retrievable archive/knowledge base."

+### Enabling the Agent with Memory Retrieval Capabilities
 The Memory usage process in Blades can be summarized in 4 steps:
 1. Create a MemoryStore (memory library)
 2. Create a MemoryTool (enabling the Agent to actively retrieve memories)
 3. Inject the MemoryTool into the Agent (WithTools), then run the conversation

 在多轮、多次会话中，Agent 往往需要“记住以前发生过什么”：例如用户偏好、历史结论、曾确认过的事实等。Blades 提供 Memory 能力，用于跨多个 Session 进行信息存储与检索，让 Agent 在新对话里也能“回忆”上下文，从而减少重复提问、提升一致性。

+### Memory 解决什么问题？
 
 - Session / State 解决的是“当前对话线程内”的组织与临时数据管理（教程在上一章展开）。
 - Memory 面向的是“跨多个 session 的历史信息”，可被检索出来辅助当前回答，可理解为 Agent 的“可检索档案库/知识库”

+### 让 Agent 具备记忆检索能力
 Blades 的 Memory 使用流程可以概括为 4 步：
 1. 创建 MemoryStore（记忆库）
 2. 创建 MemoryTool（让 Agent 能主动检索记忆）
 3. 把 MemoryTool 注入 Agent（WithTools），再运行对话
