## About the role

Judgment is the learning infrastructure for AI agents. Agents in production don't improve from prompts alone. They improve from experience: the tasks they attempt, the mistakes they make, the edge cases they hit. Here's how it works: We ingest everything your agents do in production: traces, tool calls, decisions, outcomes
