Maneesh Sharma is the COO of TestMu AI, a leading full-stack agentic AI quality engineering platform. Almost every company seemed to ship an "AI feature" last year. It felt like a mandate: Add Copilot to the dashboard, build a retrieval-augmented generation (RAG) bot for documentation, automate the support queue. But now, when I sit down with engineering leads and ask if their RAG agent is actually working, they tend to give me vibes, not data.
