Agent communication pipes are open, but Swarm still lacks five infrastructure layers for production

Agent 通信越来越简单，为什么 Swarm 依然很难落地？

Claude Code's SendMessage lets agent processes exchange text, but bare text channels can't handle concurrent overwrites, delivery guarantees, or permission boundaries. The post traces three real-world bugs to derive five infrastructure layers—exclusive locks, write isolation, conflict arbitration, and more—and maps Swarm's trade-off: 80% gain on parallel tasks, 39–70% drop on sequential reasoning.

Why it matters: Starts from real Claude Code SendMessage bugs and breaks Swarm adoption difficulty into three engineering conflicts—concurrency overwrites, delivery confirmation, permission boundaries—with concrete parallel vs sequential reasoning perf numbers. Not framework marketing; it's a...
