  "account": "Vibe coding is a practice where a developer lets a model write code and accepts it without fully reading it, relying on the short feedback loop and external correctness checks. It generally works because the model's predictions are evaluated by reality quickly, and creative coding tasks are more likely to produce a plausible result. Vibe debugging, on the other hand, is far more problematic since bugs require digging into runtime state, and an agent has never observed the runtime environment. The model can only search for common causes based on pattern matching, leading to incorrect or even harmful suggestions.\n\nThe main difference between the two lies in their feedback loops and the type of problem they tackle. Vibe coding benefits from rapid, actionable feedback, while vibe debugging grapples with the absence of real-time runtime observation. Moreover, wrong guesses in coding result in a simple rejection, whereas in debugging, incorrect assumptions can lead to adding unnecessary code like a lock that fixes no concurrency issue. A deterministic reproduction of the bug, along with a failing test, provides a solid foundation for the agent to work with, reducing the chances of getting caught in the vibe debugging death spiral.",
  "summary": "We shipped a job that sent order confirmation emails. It deduped by keeping message IDs in an in-memory Set . Clean code. An agent wrote it, I skimmed it, tests passed, staging was happy for two weeks. Then traffic spiked, autoscaling added a second instance, and a few hundred customers got the same email twice. Two Set s. Zero shared state. Obvious in hindsight, invisible in review. Here's the…",
