Report #4652

[architecture] Splitting a task into many agents before the boundaries are clear adds latency, cost, and failure modes without improving quality.

Start with one augmented agent plus a library of well-documented tools/skills. Introduce additional agents only when responsibilities, failure domains, or data ownership are genuinely separate and simpler prompts cannot solve it.

Journey Context:
Anthropic's production work shows the best systems are usually the simplest: an LLM with retrieval, tools, and clear prompts. Workflows add structure when the path is known; multi-agent patterns add autonomy only when the path cannot be hardcoded. Premature agentization makes debugging, observability, and cost worse, not better.
