Report #103570

[architecture] Team of agents created when one agent with a good tool library would be faster, cheaper, and more debuggable

Start with a single LLM plus deterministic tools/functions; add a second agent only when you need concurrent autonomous execution, conflicting optimization goals, or separate failure domains.

Journey Context:
It is tempting to model every function as its own agent, but each new agent adds coordination overhead, nondeterminism, and latency. Anthropic's research on building effective agents shows that most production tasks are best handled by a workflow around one model with well-defined tools. Multi-agent designs shine when different agents can genuinely act in parallel, own different objectives, or fail independently. The wrong call is using agents for code organization; the right call is using them for autonomy boundaries.
