What changes for users
Support-bot teams can use the kit to assess a migration, but should preserve account permissions and write approvals while comparing complete outcomes. A missing delivery date can matter more than lower latency. The published example does not establish a general cost or quality advantage for one loop.

Anthropic proposes moving suitable specialists into skills and tools loaded when needed. It retains a role for subagents when separate context, parallel work or conflicting instructions justify them. Validation, approval gates and per-user permissions still belong in tools and the runtime.
Vendor-reportedChecked: [guide]
In the guide’s support example, combining agents reduced latency but broke a previously passing process: an order lookup answered without obtaining the shipping specialist’s delivery date. The guide calls for repeated end-to-end checks covering the chains of agents used in production.
Vendor-reportedChecked: [guide]
The linked repository includes a mock support desk, a reference loop and a guided migration workflow. Its offline stand-in checks plumbing, not task quality. The README reports two real-model runs by one person on one model; the finished single-loop example and several migration steps were not tested on a real model.
