# Thread

the durable container of one conversation between a user and the agent; created, resumed, forked and archived; its history is the event log

[figure: Thread is a work at strategy scope. The drawing shows its fields and the objects that they point at.]

| property | value |
|---|---|
| kind | work |
| scope | strategy |
| key | its id |
| store | postgres |
| family | harness |



## Fields


| field | type | required | note |
|---|---|---|---|
| `id` | `id` | yes |  |
| `strategy` | `id` | yes |  |
| `user` | `id` | yes |  |
| `title` | `text` | no |  |
| `forked_from` | `id` | no |  |
| `cursor` | [EventCursor](/concepts/eventcursor) | yes | the last event a client rendered |



## Routes that use it
No route takes or returns Thread directly. The record holds it, and the objects that point at it reach it.
