[architecture] Spawning a separate agent for every distinct capability causing context-switching overhead

Default to a single agent with a rich tool/skill library. Only introduce multiple agents when there are conflicting system prompts, distinct security boundaries, or parallelizable I/O-bound tasks.

Journey Context:
The hype pushes towards multi-agent, but every agent handoff loses context and adds latency. A single smart agent with 20 tools often outperforms 5 agents passing messages because the single agent maintains the full context of the task. Multi-agent is only justified when the system prompts are fundamentally incompatible \(e.g., a strict SQL generator vs. a creative copywriter\) or for parallel execution. The tradeoff is that a single agent's prompt can get crowded with tool schemas, but tool retrieval \(RAG over tools\) solves this more elegantly than multi-agent handoffs.
