Create a new memory entry

memory_layers.entries.create(memory_layer_id, **kwargs) -> MemoryEntryDetail { content, metadata, spec, info }

POST/v1/workspaces/{workspaceId}/memory_layers/{memoryLayerId}/entries

Creates a new entry in a memory layer. Returns the detail view, including the resolved content body.

ParametersExpand Collapse

workspace_id: String

memory_layer_id: String

metadata: CreateResourceMetadata { name, bundle_key, external_id, labels }

CreateResourceMetadata contains the user-provided fields for creating a workspace-scoped resource. Read-only fields (id, account_id, workspace_id, profile_id, created_at) are excluded since they are set by the server.

Human-readable name for the resource (e.g., “Customer Support Agent”, “Email Tool”)

bundle_key: String

Optional bundle ownership key. See ResourceMetadata.bundle_key.

external_id: String

External ID for the resource (e.g., a workflow ID from an external system)

labels: Hash[Symbol, String]

Arbitrary key-value pairs for categorization and filtering Examples: {“environment”: “production”, “team”: “platform”, “version”: “v2”}

spec: MemoryEntryCreateSpec { key, content, description, upload_id }

MemoryEntryCreateSpec is the input shape for CreateMemoryEntry. It accepts either inline content or a reference to a completed Upload; exactly one of the two must be set.

key: String

See MemoryEntrySpec.key for the full rule set. Same constraints apply here.

content: String

Inline content, written directly into the entry.

description: String

upload_id: String

ID of a COMPLETE Upload. The server reads the object from storage, copies its bytes into the entry, and marks the upload consumed.

ReturnsExpand Collapse

class MemoryEntryDetail { content, metadata, spec, info }

MemoryEntryDetail is the full representation of an entry, including the resolved content body. Returned by GetMemoryEntry, CreateMemoryEntry, and UpdateMemoryEntry.

content: String

The resolved body of the entry. For entries created or updated via an upload_id, this is the ingested content, not the original upload handle. May be empty; an entry with only a key and description is valid (e.g., a stub skill being drafted, or an entry where the frontmatter alone is the payload).

metadata: ResourceMetadata { id, account_id, created_at, 6 more }

Standard metadata for persistent, named resources (e.g., agents, tools, prompts)

id: String

Unique identifier for the resource (prefixed ULID, e.g., “agent_01HXK…”)

account_id: String

Account this resource belongs to for multi-tenant isolation (prefixed ULID)

created_at: Time

Timestamp when this resource was created

formatdate-time

Human-readable name for the resource (e.g., “Customer Support Agent”, “Email Tool”) Required for resources that users interact with directly

profile_id: String

ID of the actor (user or service account) that created this resource

workspace_id: String

Workspace this resource belongs to for organizational grouping (prefixed ULID)

bundle_key: String

Optional bundle ownership key. When set, indicates the resource is managed by a configuration bundle identified by this key. Used by BulkWorkspaceResources.Apply to track which resources belong to which bundle for reconciliation / soft-delete on re-apply.

external_id: String

External ID for the resource (e.g., a workflow ID from an external system)

labels: Hash[Symbol, String]

Arbitrary key-value pairs for categorization and filtering Examples: {“environment”: “production”, “team”: “platform”, “version”: “v2”}

spec: MemoryEntrySpec { key, description }

MemoryEntrySpec is the metadata portion of an entry — the fields that identify and describe it, without the body. It appears on both the summary (MemoryEntry) and detail (MemoryEntryDetail) views.

key: String

The lookup key for this entry within its layer. Must conform to the S3 object key safe-characters spec: ASCII alphanumerics and the special characters !, -, _, ., *, ’, (, ), and /. Forward slashes may be used to suggest hierarchy (e.g., “skills/postmortem/write”), but lookups are flat — the key is a single opaque string, not a path.

Additional rules enforced by the service:

May not begin or end with /
May not contain consecutive slashes (//)
May not begin with reserved prefixes (cadenya/, system/)
Case-sensitive
Unique within the parent layer

For skills entries, this key is also the id the model passes to memory_load_skill when it decides to load the entry’s content.

description: String

One-line “when to use this” hint shown in the frontmatter manifest for skills entries. The model uses this to decide whether to load the body, so it should be written for the model as the audience. Ignored for layer types that do not advertise frontmatter.

info: MemoryEntryInfo { created_by, memory_layer }

created_by: Profile { metadata, spec }

A profile identifies a user or non-human principal (such as an API key) at the account level. Profiles are account-scoped and can be granted access to multiple workspaces.

metadata: AccountResourceMetadata { id, account_id, name, 3 more }

AccountResourceMetadata is used to represent a resource that is associated to an account but not to a workspace.

id: String

Unique identifier for the resource (prefixed ULID, e.g., “apikey_01HXK…”)

account_id: String

Account this resource belongs to for multi-tenant isolation (prefixed ULID)

Human-readable name for the resource (e.g., “Customer Support Agent”, “Email Tool”) Required for resources that users interact with directly

profile_id: String

external_id: String

External ID for the resource (e.g., a workflow ID from an external system)

labels: Hash[Symbol, String]

Arbitrary key-value pairs for categorization and filtering Examples: {“environment”: “production”, “team”: “platform”, “version”: “v2”}

spec: ProfileSpec { type, email, name }

Configuration for a profile.

type: :PROFILE_TYPE_UNSPECIFIED | :PROFILE_TYPE_USER | :PROFILE_TYPE_API_KEY | :PROFILE_TYPE_SYSTEM

Whether this profile represents a human user, an API key, or a system principal.

formatenum

One of the following:

:PROFILE_TYPE_UNSPECIFIED

:PROFILE_TYPE_USER

:PROFILE_TYPE_API_KEY

:PROFILE_TYPE_SYSTEM

email: String

Email address of the profile. Required and unique within an account for user profiles.

Display name (e.g., “Bobby Tables”).

memory_layer: ResourceMetadata { id, account_id, created_at, 6 more }

Standard metadata for persistent, named resources (e.g., agents, tools, prompts)

id: String

Unique identifier for the resource (prefixed ULID, e.g., “agent_01HXK…”)

account_id: String

Account this resource belongs to for multi-tenant isolation (prefixed ULID)

created_at: Time

Timestamp when this resource was created

formatdate-time

Human-readable name for the resource (e.g., “Customer Support Agent”, “Email Tool”) Required for resources that users interact with directly

profile_id: String

ID of the actor (user or service account) that created this resource

workspace_id: String

Workspace this resource belongs to for organizational grouping (prefixed ULID)

bundle_key: String

external_id: String

External ID for the resource (e.g., a workflow ID from an external system)

labels: Hash[Symbol, String]

Arbitrary key-value pairs for categorization and filtering Examples: {“environment”: “production”, “team”: “platform”, “version”: “v2”}
