Hamel Husain on building custom LLM output review interfaces domain experts will use

Hamel Husain and Shreya Shankar answer what makes a good custom interface for reviewing LLM outputs: since domain experts should review logs, generic observability dashboards don't cut it — build your own annotation tool. Key recommendations: render traces in domain-native form (emails as emails, code with syntax highlighting) with less-important details collapsed; keep reviewers in flow with progress indicators and hotkeys; and support clustering, filtering, and search so reviewers can spot recurring failure modes. You rarely need every feature — make a judgment call for your domain.
