[architecture] Prematurely adopting a multi-agent architecture when a single agent with a tool/skill library suffices

Start with a single agent plus a dynamically loaded skill/tool library. Only graduate to multi-agent if you hit context window limits, need isolated permission boundaries, or require concurrent execution of independent sub-tasks.

Journey Context:
Multi-agent systems are architecturally seductive but introduce massive complexity: state synchronization, handoff failures, and latency. A single LLM with a well-described set of tools can often route between capabilities internally via tool calling much more reliably than an orchestrator routing to separate LLMs. Multi-agent is only justified when the total system prompt and tool definitions exceed the context window, when tools require mutually exclusive security scopes, or when tasks can run in parallel to save time.
