How to track prompt changes during AI agent testing?

A client asked me to upgrade their AI agent that handles site automation and customer support. We ran into some issues during the rollout because the prompts started acting super glitchy. The outputs are all over the place now and it is tough to diagnose. Does anyone know a service that tracks prompt performance changes while we test this bot?

Small tweaks to LLM parameters can completely wreck the final responses. You change one word in the system instructions and the whole bot begins to hallucinate or talk nonsense to users. It helps to log every single run into a local file to catch where the logic breaks. You can also run side-by-side comparisons of the old and new outputs to spot the differences.

Version control becomes super complicated when developers run dozens of test scenarios at once. Teams need a proper environment that visually maps out how each adjustment alters the behavior of the bot over time. You can use the service for prompt optimization here https://eignex.com/ . The dashboard displays previous iterations so you can pinpoint exactly which update caused the drop in quality. It provides a clear overview of the test runs and helps get the system back on track quickly.
