When to Use One Agent vs. a Multi-Agent Workflow

More agents is not always better. The right number depends on the task complexity, quality requirements, and operational overhead you are willing to manage.

When One Agent Is Enough

Use a single agent when the task is self-contained — all required context fits in one prompt, the output is a single deliverable, and no specialized knowledge beyond the agent's expertise is needed. Blog posts, code fixes, research summaries, and data analysis often work perfectly with one agent.

When You Need Multiple Agents

Switch to multi-agent when the task requires different types of expertise (research + writing + SEO), when the output needs independent quality checks (writer + reviewer), or when the work volume exceeds what one agent can handle in a reasonable time. Multi-agent workflows add coordination cost but increase quality and throughput.

The Coordination Tax

Every additional agent in a workflow adds coordination overhead: context passing between agents, dependency management, and review of intermediate outputs. A 5-agent pipeline does not produce 5x the quality of a single agent — it produces different quality through specialization, at the cost of more management complexity.

The Decision Framework

Ask three questions: Does this task require multiple types of expertise? Would an independent review meaningfully improve quality? Is the volume too high for one agent? If you answer yes to any of these, consider multi-agent. If all answers are no, keep it simple with one agent.
