System-managed layers cannot be assigned to objective stacks via the API and cannot be mutated by clients — their lifecycle is controlled entirely by the runtime. # Entries ## List memory entries `client.MemoryLayers.Entries.List(ctx, memoryLayerID, query) (*CursorPagination[MemoryEntry], error)` **get** `/v1/memory_layers/{memoryLayerId}/entries` Lists all entries in a memory layer ### Parameters - `memoryLayerID string` - `query MemoryLayerEntryListParams` - `Cursor param.Field[string]` Pagination cursor from previous response - `IncludeInfo param.Field[bool]` When set to true you may use more of your alloted API rate-limit - `Limit param.Field[int64]` Maximum number of results to return - `Prefix param.Field[string]` Filter by key prefix (e.g., "skills/postmortem/" to list all entries under that hierarchy). Matches against the entry's key, not its name. - `SortOrder param.Field[string]` Sort order for results (asc or desc by creation time) ### Returns - `type MemoryEntry struct{…}` MemoryEntry is a single keyed value within a MemoryLayer. Entries are addressed by their key, which follows the S3 object key safe-character convention (see MemoryEntrySpec.key for the full rule). Keys are unique within a single layer; the same key may appear in multiple layers, in which case the LIFO stack-walk determines which one wins for a given objective. MemoryEntry is the summary shape, returned by ListMemoryEntries. It does not carry the entry body — callers that need the body must fetch the entry individually via GetMemoryEntry, which returns a MemoryEntryDetail. - `Metadata ResourceMetadata` Standard metadata for persistent, named resources (e.g., agents, tools, prompts) - `ID string` Unique identifier for the resource (prefixed ULID, e.g., "agent_01HXK...") - `AccountID string` Account this resource belongs to for multi-tenant isolation (prefixed ULID) - `CreatedAt Time` Timestamp when this resource was created - `Name string` Human-readable name for the resource (e.g., "Customer Support Agent", "Email Tool") Required for resources that users interact with directly - `ProfileID string` ID of the actor (user or service account) that created this resource - `WorkspaceID string` Workspace this resource belongs to for organizational grouping (prefixed ULID) - `ExternalID string` External ID for the resource (e.g., a workflow ID from an external system) - `Labels map[string, string]` Arbitrary key-value pairs for categorization and filtering Examples: {"environment": "production", "team": "platform", "version": "v2"} - `Spec MemoryEntrySpec` 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.

You know the deal. - `const ProfileSpecTypeProfileTypeUser ProfileSpecType = "PROFILE_TYPE_USER"` - `const ProfileSpecTypeProfileTypeAPIKey ProfileSpecType = "PROFILE_TYPE_API_KEY"` - `const ProfileSpecTypeProfileTypeSystem ProfileSpecType = "PROFILE_TYPE_SYSTEM"` - `Email string` Email address of the user (required, unique per account) - `Name string` Display name for the user (e.g., "Bobby Tables") - `MemoryLayer ResourceMetadata` Standard metadata for persistent, named resources (e.g., agents, tools, prompts) ### Memory Entry Create Spec - `type MemoryEntryCreateSpec struct{…}` 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` - `Title string` - `UploadID string` ID of a COMPLETE Upload. The server reads the object from storage, copies its bytes into the entry, and marks the upload consumed. ### Memory Entry Detail - `type MemoryEntryDetail struct{…}` 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, title, and description is valid (e.g., a stub skill being drafted, or an entry where the frontmatter alone is the payload). - `Metadata ResourceMetadata` Standard metadata for persistent, named resources (e.g., agents, tools, prompts) - `ID string` Unique identifier for the resource (prefixed ULID, e.g., "agent_01HXK...") - `AccountID string` Account this resource belongs to for multi-tenant isolation (prefixed ULID) - `CreatedAt Time` Timestamp when this resource was created - `Name string` Human-readable name for the resource (e.g., "Customer Support Agent", "Email Tool") Required for resources that users interact with directly - `ProfileID string` ID of the actor (user or service account) that created this resource - `WorkspaceID string` Workspace this resource belongs to for organizational grouping (prefixed ULID) - `ExternalID string` External ID for the resource (e.g., a workflow ID from an external system) - `Labels map[string, string]` Arbitrary key-value pairs for categorization and filtering Examples: {"environment": "production", "team": "platform", "version": "v2"} - `Spec MemoryEntrySpec` 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. - `Title string` Short human/LLM-readable title shown in the frontmatter manifest for skills entries. Ignored for layer types that do not advertise frontmatter. - `Info MemoryEntryInfo` - `CreatedBy Profile` Profile represents a human user at the account level. Profiles are account-scoped resources that can be associated with multiple workspaces through the Actor model.
