SummaryPendo built Novus, an AI agent that detects usability issues in live applications and auto-generates code fixes from behavioral data and session replays. The team used LangSmith to trace, evaluate, and monitor the agent, reporting 90%+ accuracy on PM-reviewed evals and a production ship in days.
Why it mattersA real production agent case study, but mostly a vendor guest post; the PM-developer feedback-loop framing is the one durable insight worth extracting.
