name	differential-review
description	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.

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

Rationalizations (Do Not Skip)

Rationalization	Why It's Wrong	Required Action
"Small PR, quick review"	Heartbleed was 2 lines	Classify by RISK, not size
"I know this codebase"	Familiarity breeds blind spots	Build explicit baseline context
"Git history takes too long"	History reveals regressions	Never skip Phase 1
"Blast radius is obvious"	You'll miss transitive callers
