Report #45792
[research] Scaling agent parallelism causes cascading API failures or exponential cost spikes when a subtle prompt change makes the agent loop infinitely
Run a cheap, deterministic eval-before-scale gatekeeper check on a 5-task subset of your regression suite before allowing batch jobs or high-concurrency production deployments.
Journey Context:
Agents are stateful and can get stuck in loops \(e.g., repeatedly calling a failing tool due to a misunderstood error message\). If you scale a looping agent to 100 parallel instances, you burn through rate limits and budget instantly. A pre-flight eval checks step-count bounds and tool-call frequency before unlocking high-throughput scaling.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
