Bring customer context into the review
Lunary connects messages and user reactions to the agent calls behind a reply. Product and engineering teammates can inspect the same interaction, share prompt drafts and test changes in the playground.
Decide how you want to test
LangWatch supports simulated multi-turn agent tests as well as evaluations. Braintrust centers experiments around datasets, tasks and scorers. Langfuse connects application traces with prompt management. Pick the workflow you intend to run repeatedly.
Review an actual failed conversation
Start a Lunary pilot with an interaction your team already struggled to diagnose. Capture message context, tool calls and feedback, then compare a prompt revision. Keep existing scenario tests until their coverage is accounted for.
