Report #10747

[research] Scaling agent concurrency or autonomy causes cost and error rates to spike uncontrollably

Establish a deterministic baseline eval suite \(success rate, trajectory adherence, cost per task\) and enforce an eval-before-scale gate: do not increase agent autonomy or parallelism if the baseline regression suite drops below threshold.

Journey Context:
Developers often scale up agents \(giving them more tools, more autonomy, higher concurrency\) hoping it increases throughput. Instead, it amplifies failure modes and costs. You must prove the agent is reliable in a sandboxed, low-concurrency environment first. Without an eval gate, you are just scaling chaos. The tradeoff is slower deployment velocity, but massive cost savings and reliability guarantees.
