What makes a good pull request description?

A good PR description answers four questions before the reviewer opens the diff: what changed, why it changed, how it was verified, and what could break. Google's engineering practices guide calls the description the first thing a reviewer reads, and reviews of well-described PRs consistently move faster because the reviewer is verifying intent instead of reverse-engineering it.

The structure this generator produces:

  • Why first. Reviewers who know the problem judge the solution faster.
  • What changed, as bullets. One meaningful change per line, not a prose wall.
  • Testing evidence. "Tested locally" is not evidence; specific steps and numbers are.
  • Breaking changes flagged loudly. The single most expensive thing a reviewer can miss.
  • Review notes. Telling reviewers where to focus respects their time budget.

Why PR descriptions speed up review

Pickup time, not reading time, dominates pull request turnaround. A clear description lowers the activation energy to start a review: the reviewer can triage in 20 seconds whether this needs deep attention now or a quick pass after lunch. Teams that adopt structured descriptions report fewer review rounds, because clarifying questions get answered in the description instead of in comment threads.

The other half of fast reviews is automating the first pass. An AI reviewer like Diffwise posts inline findings minutes after the PR opens, and even auto-generates PR summaries, so human reviewers start from a triaged diff. For the process side, read How to Reduce Pull Request Review Time.

Frequently asked questions

Is this PR description generator free?

Yes. Free, no signup, and everything runs in your browser; your input never leaves your machine.

Should every PR have a full description?

Every PR needs the why and the what; the depth should match the risk. A one-line dependency bump needs one sentence. A schema migration needs the full template with testing and rollback notes.

Can I make this a template for my whole team?

Yes. Copy the generated markdown into .github/PULL_REQUEST_TEMPLATE.md in your repo and GitHub will pre-fill it for every new pull request.

Can PR descriptions be generated automatically?

AI code review tools can draft summaries from the diff itself. Diffwise generates PR walkthroughs and reviews every push with 40+ specialist agents, so the description and the first review pass are both automated.
