Anthropic's Opus 5.5 Built a Full CRM in One Prompt With Six Parallel Agents

Claude Opus 5.5, Anthropic's latest flagship model released in September 2026, has demonstrated the scalability of agentic development by orchestrating six parallel subagents to build a functional customer relationship management system from a single natural language prompt. In the demonstration conducted by Roundtable, a single main agent handled product strategy and architecture while delegating specialized implementation tasks across two waves of five subagents working simultaneously, each responsible for distinct modules of the CRM application.
