Who developed this security methodology?

This skill is part of the Trail of Bits repository, incorporating industry-leading security research and audit workflows into the Claude Code environment.

Can I use it for quick triage of small PRs?

Absolutely. The skill includes a 'Quick Triage' mode for small changes that provides immediate risk classification and security feedback without the overhead of a full deep audit.

Does it produce a formal report?

Yes, it is designed to generate a structured markdown report file that includes evidence-based findings, line numbers, and concrete attack scenarios for every identified risk.

How does this differ from a standard AI code review?

Unlike general reviews, this skill focuses exclusively on security risk, utilizing git history, blast radius analysis, and adversarial modeling to find deep vulnerabilities that standard linters miss.

Can it handle large enterprise codebases?

Yes. It features an adaptive strategy that uses 'Surgical' analysis for projects over 200 files, focusing only on critical paths and high-risk changes to maintain efficiency.

Security & Testing

Performs high-integrity security audits of pull requests and code changes by analyzing risk, blast radius, and historical context.

About

The Differential Review skill enables Claude to perform rigorous, security-centric code reviews on PRs, commits, and diffs. Developed by Trail of Bits, it employs an adaptive strategy—scaling its analysis depth based on codebase size—to identify vulnerabilities in critical areas like authentication, cryptography, and value transfer. By combining git history analysis with adversarial modeling and blast radius calculation, it ensures that security regressions are caught and every finding is backed by concrete evidence, culminating in a detailed markdown report for your audit records.

Key Features

Automated blast radius calculation to identify the transitive impact of changes.
Comprehensive markdown report generation with line-specific evidence and git history context.
938 GitHub stars
Adaptive analysis strategies (Deep, Focused, or Surgical) tailored to project size.
Adversarial modeling to simulate exploit scenarios and evaluate exploitability.
Risk-based triage focusing on authentication, crypto, and critical business logic.

Use Cases

Auditing high-risk pull requests for security regressions and logic flaws before merging.
Generating detailed security documentation and audit reports for compliance and internal review.
Performing surgical reviews on large-scale refactors to ensure security invariants are maintained.
