Automating Pull Request Descriptions to Improve Collaboration
The author shares their experience of writing poor pull request (PR) descriptions and how they are building a GitHub app to automate the process, providing structured information to help reviewers understand the changes.
Why it matters
Improving the quality of pull request descriptions can enhance code review efficiency and collaboration within development teams.
Key Points
- 1The author often wrote vague PR descriptions like 'fix bug' or 'update styles'
- 2This forces reviewers to spend time reverse-engineering the changes and intent
- 3The author is building a GitHub app called PRDraft to automatically generate PR descriptions
- 4The app reads the diff and writes a structured description covering what changed, why, how to test, and what to watch for
Details
The author realized that they, and even senior engineers, often write poor pull request descriptions that do not provide enough context for reviewers. This happens because after completing deep work, the developer already understands the changes and feels the effort of articulating it kills the momentum. As a result, reviewers have to spend time asking questions to understand the intent behind the changes. To solve this problem, the author is building a GitHub app called PRDraft that automatically generates structured PR descriptions by reading the diff. The app aims to provide details on what was changed, why the changes were made, how to test the changes, and what to watch out for. This should save time for both the developer and the reviewer, improving collaboration.
