Memory
hm_get_overview
See the shape of a memory graph and which organizations you belong to
hm_get_overview returns a quick picture of a memory graph: how many nodes, edges, hyperedges and files it holds, which node types it uses, and when it was last written. Agents call it at the start of a conversation, together with hm_recall.
It also lists the organizations you belong to, which is how an agent learns which organization_id values it can use.
Parameters
| Parameter | Type | Description |
|---|---|---|
organization_id | string | Describe an organization graph you belong to instead of your own. Omit it, or send "none", for your own graph. |
Response
| Field | Description |
|---|---|
nodes, edges, hyperedges, files | Totals for the graph. |
type_counts | Number of nodes per node type. |
types | The node types currently in use. |
last_write_at | When the graph was last written. |
organizations | The organizations you belong to, each with organization_id and name. Absent when you belong to none. |
