Build the product experiences that make the agent improvement loop legible by owning problems end-to-end, from talking to customers to iterating on solutions. Shape the Judgment Agent to run large-scale investigations across production traces, and design interfaces that make complex reasoning trajectories legible for engineers. Construct platforms for verifying agent changes through simulated environments and trajectory replay, while building workflows that turn production findings into verified fixes. Develop swarm UX to let humans watch parallel investigations and redirect investigators, and create SDKs and terminal experiences for summoning judgment subagents mid-development.
