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

Default to a single agent with a robust tool/skill library; only scale to multi-agent when you hit distinct context window limits, require conflicting system prompts, or need true parallel execution.

Journey Context:
Multi-agent introduces coordination overhead, state synchronization hell, and cascading failures. Single agent keeps the entire context in one window, avoiding handoff loss. Developers often split agents by 'capability' prematurely, but LLMs are excellent at choosing the right tool within a single context. Only decompose when the context overflows or isolation is strictly necessary.
