Use agent-derived patterns to explain how bugs were introduced

Investigate whether short string patterns distilled from the fix commit message and diff that the agent uses to locate bug-introducing commits can be employed to automatically generate useful explanations of how the bug was introduced, particularly when the fix commit message provides little information.

Background

The study finds that the agent compresses key information about a bug into short, greppable patterns derived from the fix commit message and diff, and then uses these patterns to identify bug-introducing commits efficiently.

These patterns may encode essential aspects of the bug’s root cause. The authors suggest exploring whether such patterns can be transformed into human-understandable explanations of how the bug arose, especially in cases with uninformative commit messages.
