[frontier] How do I evaluate agent outputs that don't have deterministic right answers?

Combine code-based graders for objective checks, LLM-as-judge with structured rubrics for subjective dimensions, and periodic human calibration. Grade the outcome, not the exact trajectory. Start binary, add partial credit, and run evals in CI.

Journey Context:
Generic metrics like 'helpfulness' create false confidence and miss real regressions. Anthropic's 2026 guide emphasizes that eval design matters as much as agent design: the wrong grader can penalize a correct agent or reward a cheater. Position bias and self-preference in judges are real; mitigate with randomized order and cross-model judging. The frontier practice is building evals from error analysis and treating them as the quality gate.
