[research] Scaling agent concurrency improves throughput but overall task success rate plummets

Establish a baseline single-agent success rate \(e.g., >80%\) before increasing parallelism. Use an eval-before-scale gate: if the success rate drops below the threshold under load, throttle concurrency and investigate context window or rate-limit bottlenecks rather than adding more workers.

Journey Context:
Agents are not stateless web servers. Scaling them horizontally often hits shared state, rate limits, or context-window fragmentation, causing cascading reasoning failures. Teams often misdiagnose this as needing more agents when the real issue is degraded per-agent context quality under load.
