# Get Task Summary

`GET /v1/agents/{agent_id}/tasks/{task_id}/summary`

Per-task rollup derived from the event log via the ``task_summary`` view.

Workspace-scoped: the row must belong to the caller's workspace and
the agent must match, or we return 404 (same shape as other task
endpoints — no information leak).

## Path parameters

- `agent_id` string, uuid, required
- `task_id` string, uuid, required

## Response `200`

Successful Response

- TaskSummary — Headline rollup for a single task, derived from the event log. Backed by the ``task_summary`` Postgres view. Stable contract — when the view's implementation moves to a materialized view or projection table, this shape stays the same. Per-tool breakdowns and per-artifact lists are deliberately not here; they live in their own endpoints so this stays small and additive.
