PR Review Expert

Structured, systematic code review for GitHub PRs and GitLab MRs. Goes beyond style nits to perform blast-radius analysis, security vulnerability scanning, breaking-change detection, test-coverage delta calculation, and performance impact assessment. Produces reviewer-ready reports with prioritized findings categorized as must-fix, should-fix, and suggestions.

Keywords: PR review, code review, pull request, merge request, blast radius, security scan, breaking changes, test coverage, review checklist, code quality

Core Capabilities

Blast radius analysis — trace which files, services, and downstream consumers a diff could break; quantify severity CRITICAL/HIGH/MEDIUM/LOW.
Security scanning — detect SQL injection, XSS vectors, hardcoded secrets, auth bypass, insecure crypto, path traversal, and prototype pollution in the diff.
Breaking-change detection — flag API removals/renames, response-schema and required-field changes, DB column removals, env-var changes, and TS interface edits.
Test coverage analysis — new-code vs new-test ratio, missing tests for new public functions, deleted tests without deleted code, coverage delta.
Performance assessment — N+1 query patterns, bundle-size regressions, unbounded queries, missing indexes.
Reviewer-ready output — prioritized must-fix / should-fix / suggestion report, a 35-item checklist, and consistent comment labels.

When to Use

Before merging any PR that touches shared libraries, APIs, or database schemas.
When a PR is large (>200 lines changed) and needs structured review.
For PRs in security-sensitive code paths (auth, payments, PII handling).
After an incident, to proactively review similar code changes.
For onboarding new contributors whose PRs need thorough feedback.

Tools

Tool	Purpose	Command
`blast_radius_calculator.py`	Calculate PR blast radius from import chains / dependency trees of changed files	`git diff --name-only main...HEAD \| python scripts/blast_radius_calculator.py --root src`
`diff_analyzer.py`	Analyze a diff for risk indicators (large files, sensitive paths, config/breaking/security patterns)	`gh pr diff $PR \| python scripts/diff_analyzer.py --json`
`review_checklist_generator.py`	Generate a tailored review checklist from changed file types/patterns	`git diff --name-only main...HEAD \| python scripts/review_checklist_generator.py`

References

Load the reference that matches the task — keep this file lean and pull detail on demand:

references/review-workflow-commands.md — the 6-step review workflow with the exact gh/grep command catalog for context gathering, blast radius, security scan, breaking-change detection, coverage delta, and performance impact (plus the blast-radius severity table and coverage rules). Read when actually performing a review.
references/writeup-format-and-checklist.md — the review report template with worked examples, the complete 35-item review checklist, and the comment-label taxonomy. Read when writing up findings.
references/best-practices-and-troubleshooting.md — common reviewer pitfalls, best-practice habits, the troubleshooting table, and the success-criteria bar. Read before and after a review for quality control.
