differential-review

This Skill performs security-focused differential review on git branch changes, calculating blast radius and checking test coverage to generate comprehensive markdown reports that prevent security regressions before merging.

Differential code review analyzes only code changes rather than the entire repository, prioritizing critical areas like authentication and cryptography while leveraging git history to identify and prevent the reintroduction of past vulnerabilities.

Yes, the security audit scales for large codebases through adaptive depth, automatically adjusting analysis depth based on codebase size categories (SMALL, MEDIUM, LARGE) to ensure efficient and targeted vulnerability detection.

Run a differential review on the current branch to calculate the potential blast radius of changes and verify existing test coverage. It generates a comprehensive markdown report flagging any security risks before merging.

The best way to prevent security regressions in continuous integration is to run an automated differential review on every pull request, using git history to block the reintroduction of previously patched vulnerabilities in modified authentication and cryptography logic.
