It helps you pinpoint the first commit that introduced a regression without manually testing every change.
Ask the assistant to bisect a regression by providing the good commit, bad commit, and the predicate you want evaluated.
High-intent search queries and answers about installing and using this skill.
Git bisect identifies the first bad commit by running a binary search between known good and bad commits, applying a test predicate to each state to determine if the regression is present.
Yes, you can use a unit test, golden check, score delta, or performance threshold as the named predicate to evaluate whether a specific checked-out commit is good or bad during the automated bisect run.
Git bisect handles a dirty working tree by enforcing clean-tree validation, automatically stashing uncommitted changes before checking out the next commit, and restoring them safely after the regression search completes.
When a build fails during a bisect run, the workflow applies safe skip handling to exclude the untestable commit, allowing the binary search to continue finding the actual regression without manual intervention.
You do not need to manually run git bisect commands; you provide the good commit, bad commit, and evaluation predicate, and the automated reproducible workflow executes the binary search to pinpoint the regression.
