Agentic data science solutions often contain methodological failures

Across 220 data science tasks, most agentic DS solutions contained at least one methodological failure—data leakage, improper validation—regardless of harness or model strength, and leakage actually correlated positively with reported accuracy. Your accuracy-based evals are actively rewarding broken pipelines; if you're shipping DS agents, you need explicit leakage/validation checks because high benchmark scores are masking silent methodological errors, not confirming correctness.
Across 220 data science tasks, most agent-generated solutions had at least one methodological failure even when produced by stronger models or more complex agent harnesses. Accuracy-only evals are actively misleading here: data leakage can improve predictive scores, so production DS agents need explicit checks for leakage, validation design, and domain-methodology errors before their outputs are trusted or benchmarked.
