# 使用智能体记忆

使用记忆存储为您的智能体提供跨会话的持久记忆。

---

默认情况下，每个托管智能体会话都从全新的上下文开始。当会话结束时，智能体建立的任何状态都会消失。记忆存储让智能体可以跨会话携带信息：用户偏好、项目约定、先前的错误和领域上下文。

<Note>
所有托管智能体 API 请求都需要 `managed-agents-2026-04-01` beta 头。SDK 会自动设置 beta 头。
</Note>

## 概述

**记忆存储**是工作区范围的文本文档集合，针对 Claude 进行了优化。当您将存储附加到会话时，它会作为目录挂载在会话的容器内。智能体使用与文件系统其余部分相同的文件工具读取和写入它，并且描述每个挂载的说明会自动添加到系统提示中，告诉智能体在哪里查找。[智能体工具集](/docs/en/managed-agents/tools)是这些交互所必需的；请确保在[智能体创建](/docs/en/managed-agents/agent-setup)期间启用它。

存储中的每个**记忆**通过路径寻址，可以直接通过 API 或控制台读取和编辑，允许进行调整、导入和导出。

对记忆的每次更改都会创建一个不可变的**记忆版本**，为您提供审计跟踪和智能体写入的所有内容的时间点恢复。

## 创建记忆存储

为存储提供 `name` 和 `description`。描述会传递给智能体，告诉它存储包含什么内容。

<CodeGroup defaultLanguage="CLI">
  ````bash

记忆存储 `id`（`memstore_...`）是您在将存储附加到会话时传递的值。

### 使用内容播种（可选）

在任何智能体运行之前，使用参考材料预加载存储：

<Tip>
存储中的单个记忆上限为 100 kB（约 25k tokens）。将记忆结构化为许多小的专注文件，而不是几个大文件。
</Tip>

## 将记忆存储附加到会话

记忆存储在创建会话时在会话的 `resources[]` 数组中附加。与文件和仓库资源不同，记忆存储只能在会话创建时附加；不支持从运行中的会话添加或删除。

可选地包含 `instructions` 以提供会话特定的指导，告诉智能体应如何使用此存储。它与存储的 `name` 和 `description` 一起显示给智能体，上限为 4,096 个字符。

您也可以配置 `access`。它默认为 `read_write`（在以下示例中明确显示），但也支持 `read_only`。

<Warning>
记忆存储默认以 `read_write` 访问附加。如果智能体处理不受信任的输入（用户提供的提示、获取的网络内容或第三方工具输出），成功的提示注入可能会将恶意内容写入存储。然后后续会话将该内容读取为受信任的记忆。对于参考资料、共享查找和智能体不需要修改的任何存储，请使用 `read_only`。
</Warning>

每个会话最多支持 **8 个记忆存储**。当记忆的不同部分有不同的所有者或访问规则时，附加多个存储。常见原因：

- **共享参考资料：** 一个只读存储附加到多个会话（标准、约定、领域知识），与每个会话自己的读写存储分开。
- **映射到您产品的结构：** 每个最终用户、每个团队或每个项目一个存储，同时共享单个智能体配置。
- **不同的生命周期：** 一个比任何单个会话都长寿的存储，或者您想按自己的时间表归档的存储。

### 智能体如何访问记忆

每个附加的存储作为目录挂载在会话容器内的 `/mnt/memory/` 下，智能体使用标准[智能体工具集](/docs/en/managed-agents/tools)读取和写入它。写入会持久化回存储，并在共享它的会话之间保持同步。每个挂载的简短描述（路径、访问模式、存储 `description` 和任何 `instructions`）会自动添加到系统提示中。

`access` 在文件系统级别强制执行：`read_only` 挂载拒绝写入，而对 `read_write` 挂载的写入会生成归属于会话的[记忆版本](#审计记忆更改)。

智能体的读取和写入在[事件流](/docs/en/managed-agents/events-and-streaming)中显示为普通的 `agent.tool_use` 和 `agent.tool_result` 事件，对应于访问挂载的工具。

## 查看和编辑记忆

记忆存储可以直接通过 API 管理。用于构建审查工作流、纠正错误记忆或在任何会话运行之前播种存储。

### 列出记忆

## 审计记忆更改

对记忆的每次变更都会创建一个不可变的**记忆版本**（`memver_...`）。使用版本端点审计谁在何时更改了什么，检查或恢复先前的快照，以及使用编辑从历史记录中清除敏感内容。

版本属于存储（不是单个记忆），即使在记忆本身被删除后也会保留，因此审计跟踪保持完整。版本保留 30 天；但是，最近的版本始终保留，无论时间长短，因此很少更改的记忆可能会保留超过 30 天的历史记录。实时 `memories.retrieve` 调用始终返回最新版本；版本端点为您提供保留的历史记录。

没有专用的恢复端点；要回滚，检索您想要的版本并使用 `memories.update` 将其 `content` 写回（如果父记忆已被删除则使用 `memories.create`，因为版本比其父记忆存活更久）。

过去的记忆版本可能会在 30 天后删除。要更长时间保留记忆历史记录，请通过 API 导出版本。

### 列出版本

列出存储的版本历史记录，最新的在前。以下示例过滤到单个记忆的历史记录：

<CodeGroup defaultLanguage="CLI">
  ````bash

### 编辑版本

编辑会清除历史版本中的内容，同时保留审计跟踪（谁做了什么，何时）。用于合规工作流，例如删除泄露的密钥、PII 或用户删除请求。

作为实时记忆当前头的版本不能被编辑。首先写入新版本（或删除记忆），然后编辑旧版本。

## 管理记忆存储

除了 [`create`](/docs/en/api/beta/memory_stores/create)，记忆存储还支持 [`retrieve`](/docs/en/api/beta/memory_stores/retrieve)、[`update`](/docs/en/api/beta/memory_stores/update)、[`list`](/docs/en/api/beta/memory_stores/list)、[`archive`](/docs/en/api/beta/memory_stores/archive) 和 [`delete`](/docs/en/api/beta/memory_stores/delete)。

### 列出存储

列出工作区中的存储。默认排除已归档的存储；传递 `include_archived: true` 以包含它们。

<CodeGroup defaultLanguage="CLI">
  ````bash

### 归档存储

归档使存储变为只读并防止其附加到新会话。归档是单向的；没有取消归档。

<CodeGroup defaultLanguage="CLI">

  ````php
  $client->beta->memoryStores->archive($store->id);

  ````ruby
  client.beta.memory_stores.archive(store.id)
  ````

</CodeGroup>

有关完整参数和响应架构，请参阅[归档记忆存储参考](/docs/en/api/beta/memory_stores/archive)。

要永久删除存储及其所有记忆和版本，请使用 [`memory_stores.delete`](/docs/en/api/beta/memory_stores/delete)。

## 限制

当此功能处于 beta 阶段时，默认容量和速率限制适用于记忆存储。如果您需要更高的限制，请[联系支持](https://support.claude.com)。
