Report #43077
[research] Scaling agent parallelism or tool count causes cascading failures and budget overruns
Implement eval-before-scaling: rigorously evaluate the single-agent, single-threaded baseline with a limited toolset before increasing parallelism, context window, or tool access.
Journey Context:
Developers often throw more agents or more tools at a failing workflow, assuming parallelism will solve latency or capability issues. However, agent errors compound multiplicatively in multi-agent systems. A 90% success rate in a single agent drops to 81% \(0.9^2\) in a two-agent handoff. Scaling an untested agentic architecture just scales failure and costs. You must prove high single-agent reliability first.
