Production traffic gives agents the context to find the right service and gives CI a repeatable way to verify the result. Start here ## Start with the evidence [![Your AI agent is fixing the wrong service](https://speedscale.com/_astro/featured-image.CkCmsx5m_Z1cXX7I.webp)](https://speedscale.com/blog/ai-rework-tax/) ### [Your AI agent is fixing the wrong service](https://speedscale.com/blog/ai-rework-tax/) I tested 100 bugs across 240 microservices the model has never seen. Alert only: 51% pass rate, wrong service 34% of the time. Traffic captures: 77%.
