Decision

What the current evidence supports

Agent-assisted assessment · independently reviewed · 2026-09-30

Use as one controlled evaluation component with a pinned version and inspected failures.

Why
Independent use demonstrates a practical benchmark, while evaluator defects and simulator dependence limit interpretation of aggregate scores.
Next
Inspect task-level outcomes, repeat runs, and add evaluations with real users and production-specific policies before deployment decisions.

Constraints

Blockers

  • Evaluator defects can produce false passes and false failures.
  • Simulated users limit transfer to real customer interactions.
  • Version and domain changes can invalidate score comparisons.
  • Successor adoption reduces the predecessor's role in current headline comparisons.
