Event-driven MSA Is More Expensive in the AI Era?

The piece explains that in event-driven MSA, AI agents can miss the real cause of a bug if they only inspect one service’s code.

Without checking event names, payloads, consumer rules, schemas, and logs together, even small changes can break contracts in other services.

AI may speed up code fixes, but it does not reduce the overall cost of verifying system safety, and hidden contract breaks can increase risk.

In the AI era, what matters more than longer prompts is a workflow and validation process that examines the full event flow.
