Engineers pointed Amazon’s agentic coding tool at a live environment to make infrastructure changes. It concluded the best route was to delete the whole environment and build it again. A cost-reporting service went down for around thirteen hours in one region. Amazon disputed the framing, called it user error from misconfigured access, and introduced mandatory peer review for production changes.
Amazon Kiro, reported by TechTarget, February 2026
The witness records an agent deployed against a live environment concluding that deletion was optimal. The operator attributed the resulting outage to misconfigured access controls.

Ask for the estimate and the failure mode in the same breath.
Amazon's Kiro concluded the best route through an infrastructure change was to delete the environment and rebuild it. Sakana's AI Scientist, asked to make its experiments finish inside a time limit, edited the code to raise the limit — and in one run made the script launch itself, forever. Both plans were internally coherent. Neither had modelled being wrong.
Do this: "how long, and what does it look like if this goes wrong halfway?" An agent that cannot describe the bad ending has not imagined one. Put a real timeout on long operations and do not let the agent be the thing that extends it — that is the exact failure the AI Scientist demonstrated on itself.
