https://video.ut0pia.org/videos/watch/034c6ae6-be02-4a23-a987-5723f5986728 Instead of getting paged at midnight and starting to dig, you wake up to an issue that has already been investigated: the traces pulled, the root cause found, and a pull request with the fix waiting for review. That is what Arize built with Signal, and Jason Lopatecki walks through the anatomy of it. The unlock is boring and specific: traces on a filesystem. A skill pulls the relevant production traces and logs down as files into the repo, right next to the code, sometimes ten megabytes of them, because coding harnesses like Claude Code are magical with files and hopeless with a dashboard. From there the agent has the exact code path the software took, not a guess among a million branches, and can produce a real fix. You pick the harness, the sandbox, and the skills, and Arize can run it inside your VPC, because companies like Uber and Booking will not point production systems at an external model. The deeper shift is that observability stops being a dashboard you click and becomes the smoke a system throws off for agents to read, which is why you now log and trace ten times more, not less. He is honest about the limits: a one line fix is the easy case, bigger fixes still need a human to drive, and the job moves from responder to reviewer.
