Agent Skills: Pull Request Enhancement

Pull Request Enhancement

Workflow

1. Run git diff <base>...HEAD --stat to identify changed files and scope
2. Categorise changes: source, test, config, docs, build, styles
3. Generate the PR description using the template below
4. Add a review checklist based on which file categories changed
5. 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>
