[counterintuitive] Do multi-agent frameworks outperform single agents on complex tasks

Start with a single, well-prompted agent with a clear workflow before graduating to multi-agent; use multi-agent for architectural decoupling and parallelization, not as a magic accuracy booster.

Journey Context:
Developers assume 'more agents = more intelligence' \(like a team of humans\). In reality, multi-agent systems often suffer from error cascades, hallucination amplification, and context loss between agents. A single agent with a well-defined scratchpad and tools often outperforms a multi-agent setup on the same task, while multi-agent adds massive overhead and non-determinism.
