arXiv 2607.22883 documents a "misguidance effect": show an LLM buggy code and ask for unit tests, and it does two bad things at once, generating more tests that assert the erroneous behavior as correct and fewer bug-exposing tests. Buggy code skews preference toward tests that ratify the bug. The fix is a one-line prompt change: replace the code-under-test with an LLM-generated specification docstring so the model targets intended behavior. Also improves multi-round feedback-driven pipelines. (arXiv 2607.22883)
