# Preview Playground Report

`POST /api/v1/alerts/preview/playground-report`

Preview what a playground report would look like.

Regenerates the session through the same ask pipeline a scheduled run uses,
so the preview shows the content the next delivery would carry — it costs an
LLM run and appends a new assistant turn to the session, but nothing is
delivered and no run is recorded. Blocks for the length of that run.

Distinct from ``/preview`` because playground reports have no metric_config
and need no ClickHouse access.

## Request body

- PlaygroundReportPreviewRequest — Preview a playground report from a Studio session, before/without saving a rule. Regenerates the session through the same ask pipeline a scheduled run uses, then renders the fresh answer — no delivery, and the turns the run appends are discarded once rendered.
  - `session_id` string, required
  - `content_scope` string — first_query | last_answer | full_chat
  - `report_name` string, nullable — The rule's name (or the name typed into an unsaved form). Reaches the subject line, so pass it for the preview to match what a scheduled run would send. Falls back to a placeholder.
