…PI agents via AbortSignal, and process their intermittent stream (#15139) ## Background PR #15013 added Interactions API support but two background-mode gaps remained: aborting a call didn't stop the run on Google's side (kept billing), and `streamText` against an agent buffered everything until the run finished instead of actually streaming. ## Summary - Poll loop now fires `POST /interactions/{id}/cancel` on abort. - Agent `doStream` now opens `GET /interactions/{id}?stream=true` and reconnects with `last_event_id` on idle disconnects. - Existing `streamText` agent examples switched to `fullStream` with dimmed `reasoning-delta` output; new abort examples + shared SIGINT→AbortController helper. ## Manual Verification - `aif examples/ai-functions/src/stream-text/google/interactions-agent-single-turn.ts` — reasoning prints incrementally. - `aif examples/ai-functions/src/generate-text/google/interactions-agent-abort.ts` — server-reported status flips to `cancelled`. ## Checklist - [x] All commits are signed (PRs with unsigned commits cannot be merged) - [x] Tests have been added / updated (for bug fixes / features) - [ ] Documentation has been added / updated (for bug fixes / features) - [x] A _patch_ changeset for relevant packages has been added (for bug fixes / features - run `pnpm changeset` in the project root) - [x] I have reviewed this pull request (self-review) ## Future Work - `webhook_config` — deferred until the AI SDK has a fire-and-forget primitive; polling alongside a webhook defeats the point. - `background: true` for model-id calls — API rejects every documented model today, it seems the API only supports this parameter in combination with `agent`.
