[architecture] Over-decomposing tasks into multiple agents when a single agent with a skill library suffices

Default to a single-agent-plus-tools architecture. Only introduce multiple agents when you need isolated memory contexts, distinct system prompts, or true parallel execution.

Journey Context:
The 'multi-agent' buzzword leads developers to create swarms for tasks that one capable LLM could handle with a well-defined tool suite. Multi-agent introduces massive overhead: context synchronization, routing failures, and the loss of shared working memory. A single agent maintains a unified context window, avoiding the token cost and latency of passing context back and forth. Split agents only when context windows overflow, permissions must be strictly isolated, or independent parallel tasks require distinct personas.
