[architecture] Over-fragmenting tasks into multiple agents instead of using a single agent with tools

Keep a single agent with a rich tool library unless you hit context window limits, need distinct permission boundaries, or require independent parallel execution.

Journey Context:
Developers often treat agents like microservices, splitting them by function \(e.g., 'search agent', 'summarize agent'\). This introduces massive overhead in context synchronization, handoff failures, and latency. A single LLM with the right tools maintains coherent context and is far more reliable. Multi-agent should be reserved for true distributed systems requirements: isolation, parallelism, or context overflow.
