Summary from the TLDR Data newsletter

PostHog tests AI agents on real tasks, such as finding the bugs behind 33 past incidents, where its review agent caught 62%, or checking whether playback failures affected real users. It isolates each test so agents cannot copy earlier answers and is building resettable environments with fixed data to make comparisons fair.
