[research] Scaling up agent parallelism increases costs but doesn't improve task success rate

Run a localized, single-threaded eval suite to establish a baseline success rate before increasing parallelism or retries. Only scale parallelism if the base success rate is greater than 70%.

Journey Context:
Developers often try to overcome an agent's fundamental inability to complete a task by running it multiple times. If the base success rate is low \(e.g., 20%\), scaling just burns tokens. Eval-before-scaling ensures you fix the prompt/tool logic first. Parallelism only helps overcome intermittent LLM failures, not systematic logic gaps.
