Alpha.2 changes tool and subagent contracts and removes Agent Team outbox delivery. Alpha.2 removes both tool presentation, returns subagent identifiers immediately, and requires callers to handle continuation/wait operations. Agent Team messages now go directly to the target Inbox; the separate outbox, automatic retries and resend deduplication are removed. A successful send means Inbox acceptance, not model processing or a synchronous storage flush. Per-row instruction-home overrides are ignored.
Channel: preview-or-beta; alpha-only. Half: both. Date: 2026-10-09 (alpha.2 release).
Operator consequence: Migrate tool presentation to native or ptc, support session/wait in custom runtimes, and handle failed Team sends explicitly without assuming retries or duplicate suppression. Select instruction homes using process environment. The direct-delivery simplification removes a durable delivery promise as well as code.
