[architecture] Deciding between a single agent with tools versus multiple specialized agents

Default to a single agent with a skill/tool library. Only introduce multiple agents if you need parallel execution, strict context window isolation, or fundamentally divergent system prompts.

Journey Context:
Developers often assume multiple agents are inherently more capable. However, multi-agent systems introduce massive overhead in state synchronization, routing, and context sharing. LLMs suffer from context fragmentation when information is split across agents. A single agent with a well-structured tool library maintains coherent context and is far easier to debug. Multi-agent is only the right call when the context required for one task would completely evict the context required for another, or when tasks must run concurrently.
