SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Performs security-focused differential review of code changes (PRs, commits, diffs). Adapts analysis depth to codebase size, uses git history for context, calculates blast radius, checks test coverage, and generates comprehensive markdown reports. Automatically detects and prevents security regressions.

Core Features & Use Cases

  • Baseline context building and phase-driven analysis for triage, code review, and adversarial assessment.
  • Blast-radius and test-coverage evaluation to prioritize high-risk changes.
  • Automated markdown report generation and integration-ready artifacts for audit workflows.

Quick Start

Run the differential-review workflow on the changed code to produce a structured audit report.

FAQPage Schema
How do I automate a security audit for a code diff?

A security-focused differential review automates code diff auditing by combining baseline context, diff analysis, and adversarial planning. It detects security regressions and produces a structured markdown audit report covering blast radius and test coverage.

What is a differential code review and when do I need it?

Differential code review is a security-first analysis of code changes like PRs or commits. You need it to automatically detect and prevent security regressions by evaluating the blast radius and test coverage of modifications across your codebase.

How do I calculate blast radius and check test coverage for a pull request?

Calculate blast radius and check test coverage for a pull request by applying phase-driven differential review. This process scales analysis depth by codebase size, evaluates high-risk changes, and outputs the results within a structured markdown audit report.

Does differential review work for large codebases?

Differential review works for large codebases by automatically scaling the analysis depth according to the codebase size. It uses git history for context and evaluates high-risk changes to efficiently prevent security regressions across extensive PRs and commits.

How do I generate an audit report from git history and commit changes?

Generate an audit report from git history and commit changes by running the differential review workflow on your diffs. It uses git history for baseline context, performs adversarial assessment, and outputs integration-ready markdown artifacts for audit workflows.
