Report #99063

[counterintuitive] A high SWE-bench score means an agent is ready for production engineering.

Validate agents on live, contamination-free benchmarks and on real tasks; expect worse performance on multi-file changes, large codebases, and evolving constraints; keep humans in the loop for scoping and integration.

Journey Context:
SWE-bench-Live is a continuously updating benchmark of 1,319 recent issues across 93 repositories. Its authors report that it presents significantly greater challenges than static datasets, with low resolution rates on multi-file patches and large codebases. Complementary work on SWE-rebench shows that model performance can decline on newer temporal slices and warns of data-leakage/contamination effects. Static benchmarks are curated, pinned, and test-known; production issues are under-specified and evolving. Treat benchmark scores as an optimistic ceiling, not a guarantee of real-world readiness.
