Field notes
Trackline describes two monitoring paths: hooks that inspect coding-agent actions before they run, and checks over production traces sent through OTLP. Users can choose whether a check only records an issue or blocks the action; the model-based judge is described as off by default. The page links to experiments, including a reported 60/60 held-out-drift result for the judge, against 2 for rules alone.
