[research] Scaling up agent autonomy or parallelism causes cost and error rates to explode uncontrollably

Run eval suites on a single-agent, restricted-permission baseline first. Only grant broader tool access or increase parallelism after the eval suite proves high trajectory accuracy and zero catastrophic tool-use failures.

Journey Context:
The temptation is to give agents full autonomy immediately to see what they can do. Without evals, autonomy just scales failure. Eval-before-scaling ensures the agent's decision-making boundary is well-understood before you let it run wild in parallel or with destructive tools.
