You don't always need a multi-agent setup

The author points out that multi-agent architectures are fundamentally a **reliability/parallelism tradeoff**, not a capability upgrade. Defaulting to them blindly only increases debugging overhead. **Use a single agent if:** - Your workflow is a sequence of dependent steps (research → decide → next step). - Tasks are simple to medium complexity. - Speed and simplicity outweigh scale. - You lack the infrastructure to handle shared memory/orchestration cleanly. **Use multi-agent if:** - Tasks are naturally parallelizable (e.g., researching, auditing, and coding simultaneously). - Subtasks require genuinely different "mental models" (a broad researcher vs. a narrow synthesizer struggle to context-switch). - You have an orchestrator to delegate, monitor, and spin up agents. - Shared memory/sync is already working flawlessly; otherwise, multi-agent just adds coordination overhead. **Rule of thumb:** Single strong agent for sequential work; multi-agent for parallel, separable work.
