[architecture] When to use multiple agents instead of one agent with a large tool/skill library

Default to a single agent with a dynamic skill/tool library. Only introduce multiple agents if you hit the context window limit or require fundamentally conflicting system prompts \(e.g., coder vs. reviewer\).

Journey Context:
Multi-agent systems introduce severe coordination overhead, state synchronization issues, and routing loops. A single agent maintains a unified mental model of the task, avoiding the 'telephone game' of context passing. The only valid reasons to split agents are context window exhaustion \(where the combined prompt/tools/history exceed limits\) or diametrically opposed instructions \(an agent cannot be both strictly concise and strictly verbose\).
