[research] Scaling up agent parallelism or context window causes costs to explode and failure modes to multiply unpredictably

Freeze agent architecture and establish a regression eval suite with >90% pass rate before increasing parallelism, tool count, or context limits. Treat evals as the prerequisite gate for scaling.

Journey Context:
Developers often try to fix a struggling agent by giving it more tools, more context, or running more parallel instances. This exponentially increases the search space for the agent, leading to higher costs and more hallucinations. Scaling amplifies existing flaws. You must achieve a stable baseline on a constrained agent via evals before expanding its capabilities.
