Once the assistant launches, everyone asks about inventory, ERP times out, and order entry fails. Agents are not users—they are a new traffic source, and they may retry in loops. Core trading systems must be protected: rate limits, isolation, circuit breakers. A slower assistant can apologize; failed posting cannot. Engineering must split AI traffic from transaction traffic—keep intelligence busy, not business dead.
Integration without rate limits is handing production-database keys to the people who ask the most questions.
Protect Trading, Constrain the Assistant
AI uses a separate gateway and read replicas; writes go through a queue with concurrency caps. When error rate or latency exceeds threshold, break tool calls and return degraded responses (cache, try later). Ban unbounded retries. During peak order-entry hours, downgrade assistant queries to summaries—not full-table scans.
- Per-tenant, per-tool quotas—over limit means queue, not punch-through.
- Transaction APIs outrank analytics APIs—priority written into the gateway.
- Drill: stress-test with the assistant and verify order entry still succeeds.

Circuit Breaking Is Loyalty to Operations
The XYN digital intelligence system layers assistant queries below transaction documents with rate limits on by default. Agent engineering includes this protection—otherwise a POC at scale becomes an incident. A slow assistant can wait; stopped trading taxes the whole company for AI.
Before launch, load-test: when agents max out, does order-entry success still meet target? If not, circuit-break first—then talk smarter models.
