Analysis

A recorded agent failure can be more than an anecdote. NVIDIA's NeMo tutorial, built on fictional-company traces, shows one way to turn it into a test.

Hermes runs in an OpenShell sandbox. Compass links recurring findings to traces, Eval Author helps create custom evaluations, and harness changes are checked on development and held-out tasks.

My view: the useful move is from anecdote to repeatable check, with held-out tasks keeping the repair honest. Silver Owl has not run this, and it is no general safety proof.

Why it matters

Failures are more useful when tied to repeatable checks and held-out evaluation.
