[architecture] When to use multiple agents instead of one agent with a skill library

Use a single agent with a tool/skill library for sequential tasks requiring tight shared context. Use multi-agent only when tasks are parallelizable, require distinct system prompts, or need isolated context windows to prevent attention dilution.

Journey Context:
Developers default to multi-agent for complex systems, but LLMs suffer from context dilution when overloaded with unrelated tools. A single agent with a well-structured skill library often outperforms a swarm for linear workflows because it avoids the latency and state-sync overhead of inter-agent communication. Multi-agent shines when isolation is strictly needed \(e.g., a Coder and a Reviewer\) or for parallel execution.
