[research] When to scale up agent parallelism or add more tools without degrading reliability

Run your regression eval suite against the proposed scaling change. Only increase parallelism or agent count if the success rate on the eval suite remains above your threshold. Establish a baseline eval score for a single agent, and treat scaling as a parameter to be tested.

Journey Context:
A common mistake is assuming that adding more agents or running them in parallel will strictly improve throughput without affecting quality. In reality, increased parallelism often leads to higher rates of race conditions, context collisions, or rate-limit induced failures. Scaling an unreliable agent just gives you faster failures. You must eval-before-scale to ensure the system's coordination mechanisms hold up under load.
