Optional<String> content

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).

Optional<String> path

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, and must be NFC-normalized. Paths are case-sensitive. The memory's id is preserved across renames. Omit to leave the path unchanged.

minLength2

maxLength1024

Optional<BetaManagedAgentsPrecondition> precondition

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.

Returns

class BetaManagedAgentsMemory:

A memory object: a single text document at a hierarchical path inside a memory store. The content field is populated when view=full and null when view=basic; the content_size_bytes and content_sha256 fields are always populated so sync clients can diff without fetching content. Memories are addressed by their mem_... ID; the path is the create key and can be changed via update.

String id

Unique identifier for this memory (a mem_... value). Stable across renames; use this ID, not the path, to read, update, or delete the memory.

String contentSha256

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.

long contentSizeBytes

Size of content in bytes (the UTF-8 plaintext length). Always populated, regardless of view.

formatint32

LocalDateTime createdAt

A timestamp in RFC 3339 format

formatdate-time

String memoryStoreId

ID of the memory store this memory belongs to (a memstore_... value).

String memoryVersionId

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.

String path

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 type

LocalDateTime updatedAt

A timestamp in RFC 3339 format

formatdate-time

Optional<String> content

The memory's UTF-8 text content. Populated when view=full; null when view=basic. Maximum 100 kB (102,400 bytes).
