The loop pattern uses a generator and critique agent in an iterative cycle until output meets specific conditions. The coordinator pattern acts as a smart project manager delegating subtasks to specialized sub-agents. The agent-as-tool pattern differs by keeping the primary agent in full control, treating sub-agents as stateless tools. Each pattern is demonstrated with code examples and a web UI, with trade-offs discussed around latency, cost, flexibility, and complexity. ## Full article daily.dev links to this article rather than hosting it.
