# List recent task sessions (root tasks + chain summary)

`GET /api/sessions`

Each item's `root` is a slim task summary by default — the full `task` text is replaced with a bounded `taskPreview` and completion/integration blobs are dropped. Pass `fields=full` to restore the full root `AgentTask`. The full root + descendant chain are on `GET /api/sessions/{rootTaskId}`.

## Query parameters

- `limit` integer, nullable
- `offset` integer, nullable
- `source` string
- `q` string
- `requestedByUserId` string
- `fields` 'full' | 'slim'

## Response `200`
