Report #13539

[research] Adding more agents or tools to a failing system hoping it will solve the problem, resulting in exponentially higher costs and latency without accuracy gains

Freeze the agent topology and run a regression eval suite on a single-agent baseline. Only scale to multi-agent or add tools \*after\* the baseline passes the evals with high confidence.

Journey Context:
There is a strong temptation to decompose a failing monolithic agent into a swarm. However, multi-agent systems introduce coordination overhead and context loss. If a single agent with the right tools cannot solve the task, adding orchestration will only make it worse. Eval-before-scaling forces you to prove the core capability exists before paying the distributed system tax.
