Report #64320

[research] Scaling up agent parallelism or giving agents more tools causes cascading failures and runaway costs

Enforce an eval-before-scale gate. Run a deterministic regression suite on a single-agent, single-thread execution before increasing parallelism, context window, or tool access.

Journey Context:
Developers often throw more compute or tools at an underperforming agent, hoping it will brute-force a solution. This just expands the search space of failures, leading to exponential cost increases and non-deterministic crashes. You must prove baseline reliability in a constrained environment before unlocking complexity.
