[architecture] When to use multiple agents vs a single agent with a skill library

Default to a single agent with tools unless you need distinct LLM profiles, isolated memory/state, or true parallel execution.

Journey Context:
Multi-agent systems introduce massive coordination overhead, state synchronization complexity, and context-passing loss. Developers often over-engineer by assigning every task to a different agent. A single agent with a well-defined tool/skill library shares a unified context window, avoiding handoff hallucinations and dropped context. Multi-agent is only justified when the agents require fundamentally different system prompts, model weights, or isolated security boundaries.
