Your Agent Writes the PR Description, but It Only Tells You What the Code Does

The PR description generated by the agent often falls short in providing crucial context for reviewers. It merely lists the changes made, but lacks essential details that would clarify the reasoning behind those changes. The description does not answer questions like what prompted the validation addition, what was discarded and why, the author's uncertainties about the new tax module, or how reviewers should focus their attention.

This lack of clarity can lead to two problematic scenarios for reviewers: approving without fully understanding or spending excessive time trying to infer the author's intentions. The agent, while producing a tidy description, does not have the incentive to highlight uncertainty since it perceives the change as already correct. To improve the review process, the author should proactively provide a concise overview addressing key points such as the reason for the change, previous attempts, remaining uncertainties, specific areas for reviewer focus, and verification commands.

By incorporating these elements, the description would become a valuable tool rather than a mere diff narration, enabling reviewers to quickly grasp the essential aspects of the change and focus their efforts on the most critical aspects.
