Differential Security Review

Security-focused code review for PRs, commits, and diffs.

Core Principles

  1. Risk-First: Focus on auth, crypto, value transfer, external calls
  2. Evidence-Based: Every finding backed by git history, line numbers, attack scenarios
  3. Adaptive: Scale to codebase size (SMALL/MEDIUM/LARGE)
  4. Honest: Explicitly state coverage limits and confidence level
  5. Output-Driven: Always generate comprehensive markdown report file

Codebase Size Strategy

Codebase Size Strategy Approach
SMALL (<20 files) DEEP Read all deps, full git blame
MEDIUM (20-200) FOCUSED 1-hop deps, priority files
LARGE (200+) SURGICAL Critical paths only
