Alex Kerss tests Buzz, an open-source workspace from Block where humans and agents share channels, threads and messages. A simple request for two agents to talk immediately produced a long loop because each mention triggered another response.
Buzz provides identities, routing, event storage, agent tools and a shared relay, but it does not automatically enforce manager-worker roles, task dependencies, joins, retries or deterministic completion. A simple manager-and-two-workers prompt succeeded, yet the language models, not an orchestration engine, were responsible for following the workflow.
Complex workflows can therefore fail through missing mentions, silent worker errors, premature manager replies or endless conversations. Alex Kerss also notes that business adoption depends on clearer hosted-service maturity, administration, compliance, storage and recovery guarantees.
