Attach a memory layer to a variation

POST/v1/workspaces/{workspaceId}/agents/{agentId}/variations/{variationId}/memory_layer_assignments

Attaches a memory layer to a variation at a given position in the variation’s baseline memory stack.

workspaceId: string

agentId: string

variationId: string

Body ParametersJSONExpand Collapse

memoryLayerId: optional string

Layer to attach. Accepts the canonical memlyr_… form or the external_id:<value> form.

position: optional number

Position in the stack. If omitted, server appends (max existing position + 1).

VariationMemoryLayerAssignment object { id, memoryLayer, position }

VariationMemoryLayerAssignment attaches a single MemoryLayer to a variation at a given position in the variation’s baseline memory stack. A variation has at most one assignment per memory_layer_id.

Variations only support whole-layer attachments — entry pinning is an objective-level capability.

id: optional string

Assignment row id — handle for removing the assignment. Distinct from the referenced memory layer’s id.

memoryLayer: optional BareMetadata { id, name }

BareMetadata contains the minimal metadata for a resource: the ID and an optional human-readable name. These are used for reference fields where the full metadata (account scoping, timestamps, labels, external IDs) is not needed — e.g., the tool references inside an agent variation spec or the tools assigned to an objective. Both fields are server-populated; clients provide IDs through sibling fields rather than by constructing a BareMetadata themselves.

id: optional string

name: optional string

Human-readable name of the referenced resource, populated by the server on reads for convenience. Absent on references to resources that do not have a name (e.g., objective tasks).

position: optional number

Position in the variation’s baseline stack. Lower values sit lower; the highest-position assignment is on top of the variation’s baseline. Gaps are fine — only relative position matters. Positions must be unique within a variation; a request that would collide with an existing assignment’s position is rejected with InvalidArgument.
