[research] Agent performance degrades unpredictably when scaling from prototype to parallel production runs

Implement eval-before-scaling: run single-threaded, trace-level evaluations on a representative sample of tasks to measure step-completion rates and token efficiency before allowing parallel execution or increased autonomy.

Journey Context:
Developers often scale agents to parallel execution hoping throughput will compensate for edge-case failures. Instead, concurrency amplifies minor context-handling bugs into systemic failures \(e.g., rate limits causing fallback logic errors\). Validating the golden path and failure modes on single traces first prevents burning compute budgets on broken loops.
