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

Default to a single agent with a tool/skill library. Only introduce multiple agents if context windows overflow, or if you need strict isolation of system prompts and independent execution loops.

Journey Context:
Multi-agent systems introduce massive coordination overhead, state synchronization issues, and routing failures. A single agent maintains a coherent context window and avoids the 'telephone game' of inter-agent messaging. The tradeoff is context length and prompt complexity; once a single agent's prompt becomes too large or the tool set too confusing for one LLM to navigate, splitting into multi-agent is justified.
