Agent observability is a means to an end: making your agent better. But observability and evals tools have traditionally failed to connect traces to meaningful actions. Agent engineering teams are left combing through traces, guessing at root causes, and writing evals manually. We built Engine to close the agent improvement loop. Engine monitors your agent's traces, creates ready-to-merge fixes, and writes evals. Now every trace becomes a fix, an eval, and a better agent. Media
