Pull Request Enhancement
When to Use
- You need to turn a git diff into a reviewer-friendly pull request description.
- You want a PR summary with change categories, risks, testing notes, and a checklist.
- The diff is large enough that reviewers need explicit structure instead of a short ad hoc summary.
Workflow
- Run
git diff <base>...HEAD --stat to identify changed files and scope
- Categorise changes: source, test, config, docs, build, styles
- Generate the PR description using the template below
- Add a review checklist based on which file categories changed
- Flag breaking changes, security-sensitive files, or large diffs (>500 lines)

Review Checklist Rules
Add checklist sections only when the matching file category appears in the diff:
| File category |
Checklist items |
| source |
no debug statements, functions <50 lines, descriptive names, error handling |
| test |
meaningful assertions, edge cases, no flaky tests, AAA pattern |
| config |
no hardcoded secrets, env vars documented, backwards compatible |
| docs |
accurate, examples included, changelog updated |
security-sensitive (auth, crypto, token, password in path) |
input validation, no secrets in logs, authz correct |
Splitting Large PRs
When diff exceeds 20 files or 1000 lines, suggest splitting by feature area:
git checkout -b feature/part-1
git cherry-pick <commits-for-part-1>
