Defined in: packages/ai/src/activities/middleware/types.ts:37

The activity an observability event describes.

Mirrors the public surface a caller reaches for: 'chat' for chat(), 'summarize' for summarize(), and the media kinds for the generate* activities. 'tts' matches the speech adapter's kind (the public discriminator avoids inventing a parallel 'speech'/'text' vocabulary). otelMiddleware maps each to its gen_ai.operation.name.

'summarize' produces text, not media, so it has no artifacts — a persistence middleware stores its run record and result and nothing else.
