AI commit message generator confidently provides incorrect suggestions

By PulseAugur Editorial · [1 sources] ·

A developer tested a commit message generation script that uses Claude, finding that the model confidently provided incorrect commit messages when faced with ambiguous or mixed changes. The script's prompt only allowed for specific commit types (feat, fix, docs, style, refactor, test, chore) and did not include an option for uncertainty or the ability to suggest splitting a commit. When presented with a diff containing both a new feature and an API migration, the model generated a single 'feat' commit message, merging the unrelated changes. Similarly, for a file rename with no content change, the model chose 'refactor' without acknowledging the ambiguity in Conventional Commits specification. AI

    What Happens When a Commit-Message Generator Can't Say "I'm Not Sure"?

    <p>A trending post this week argued that an agent isn't hallucinating when it gives a confident wrong answer — it's doing exactly what its rules told it to, because the rules never defined what "I don't know" looks like. I have a small, boring, real example of that sitting in my …
