请求参数

memory_store_idstring必填
path: 记忆库 ID（路径或查询参数）。
memory_idstring必填
path: 记忆 ID（路径或查询参数）。
memory_store_idstring必填
query: 记忆库 ID（路径或查询参数）。
viewstring可选
query: 返回投影：basic 省略内容，full 附带完整内容。
contentstring可选
New UTF-8 text content for the memory. Maximum 100 kB (102,400 bytes). Omit to leave the content unchanged (e.g., for a rename-only update).
pathstring可选
New path for the memory (a rename). Must start with `/`, contain at least one non-empty segment, and be at most 1,024 bytes. Must not contain empty segments, `.` or `..` segments, control or format characters, or the Unicode line and paragraph separators (U+2028, U+2029), and must be NFC-normalized. Paths are case-sensitive. The memory's `id` is preserved across renames. Omit to leave the path unchanged.
preconditionobject可选
Optimistic-concurrency precondition: the update applies only if the memory's stored `content_sha256` equals the supplied value. On mismatch, the request returns `memory_precondition_failed_error` (HTTP 409); re-read the memory and retry against the fresh state. If the precondition fails but the stored state already exactly matches the requested `content` and `path`, the server returns 200 instead of 409.

  取值 content_sha256
- content_sha256string可选
  Expected `content_sha256` of the stored memory (64 lowercase hexadecimal characters). Typically the `content_sha256` returned by a prior read or list call. Because the server applies no content normalization, clients can also compute this locally as the SHA-256 of the UTF-8 content bytes.

501 平台还没有实现这个端点；调用会得到下面这个响应：

平台还没有提供智能体可读写的持久记忆库。调用会返回 501（not_implemented_error），不产生副作用，官方 SDK 不会重试。

错误按 Claude Managed Agents 格式返回，参见错误码

名称	类型	说明
id	string	Unique identifier for this memory (a `mem_...` value). Stable across renames; use this ID, not the path, to read, update, or delete the memory.
content_sha256	string	Lowercase hex SHA-256 digest of the UTF-8 `content` bytes (64 characters). The server applies no normalization, so clients can compute the same hash locally for staleness checks and as the value for a `content_sha256` precondition on update. Always populated, regardless of `view`.
content_size_bytes	number	Size of `content` in bytes (the UTF-8 plaintext length). Always populated, regardless of `view`.
created_at	string	A timestamp in RFC 3339 format
memory_store_id	string	ID of the memory store this memory belongs to (a `memstore_...` value).
memory_version_id	string	ID of the `memory_version` representing this memory's current content (a `memver_...` value). This is the authoritative head pointer; `memory_version` objects do not carry an `is_latest` flag, so compare against this field instead. Enumerate the history via List memory versions.
path	string	Hierarchical path of the memory within the store, e.g. `/projects/foo/notes.md`. Always starts with `/`. Paths are case-sensitive and unique within a store. Maximum 1,024 bytes.
type	string
updated_at	string	A timestamp in RFC 3339 format
content	null \| string	The memory's UTF-8 text content. Populated when `view=full`; `null` when `view=basic`. Maximum 100 kB (102,400 bytes).
