Report #8053

[research] Scaling agent parallelism or context length causes cost and latency to explode without quality gains

Run eval suites on a single-threaded, constrained agent first. Only increase parallelism, tool count, or context window if evals prove the agent utilizes the expanded state effectively without hallucinating.

Journey Context:
Developers often add more tools or increase max\_iterations hoping to solve edge cases, but LLMs suffer from needle in a haystack and decision paralysis with too many tools. Eval-before-scaling means measuring tool selection accuracy and context utilization before granting the agent more resources. If an agent fails with 5 tools, it will likely fail worse with 10.
