Compare the conclusion as well as the prediction
The study uses paired workloads where the same candidate limitations can matter differently to the final decision. Recognizing a simulator limitation is not sufficient if the agent still chooses the wrong recommendation.
A constrained research setting
The paper covers thirteen serving-system design tasks. Its agent tools read and search files; they do not execute or modify code. Results therefore concern reasoning over supplied evidence, with limited generalization to autonomous experimentation.
What you can do

Where the evidence stops
Author-reported evaluation; no simulations or agent runs reproduced. Review can help some decisions and worsen others, so a second review is not a guarantee of correctness.
