Summary

Adds a ready-to-use Claude Code skill for security reviews using the anti-patterns guide.

Changes

  • New file: .claude/skills/security-review.md - Skill definition with instructions
  • Updated: README.md - Added installation instructions and usage examples under Option 4

Features

  • /security-review - Quick review using BREADTH (25+ patterns)
  • /security-review --deep - Deep audit using DEPTH (7 critical patterns)
  • Auto-selects DEPTH for security-critical paths (auth, payments, crypto)
  • Structured output with severity levels and actionable fixes

Installation

Users can install with:

mkdir -p .claude/skills .claude/security
curl -sL https://raw.githubusercontent.com/Arcanum-Sec/sec-context/main/.claude/skills/security-review.md -o .claude/skills/security-review.md
curl -sL https://raw.githubusercontent.com/Arcanum-Sec/sec-context/main/ANTI_PATTERNS_BREADTH.md -o .claude/security/ANTI_PATTERNS_BREADTH.md
curl -sL https://raw.githubusercontent.com/Arcanum-Sec/sec-context/main/ANTI_PATTERNS_DEPTH.md -o .claude/security/ANTI_PATTERNS_DEPTH.md

Testing

Tested the skill on a real codebase (Firebase/Next.js/Stripe auction platform) - it correctly identified potential issues and avoided false positives.

- Add .claude/skills/security-review.md skill definition
- Update README with installation instructions and usage examples
- Skill supports both BREADTH (quick reviews) and DEPTH (deep audits) modes
- Auto-selects DEPTH for security-critical paths (auth, payments, crypto)

The skill allows Claude Code users to run `/security-review` to check
their code against all 25+ anti-patterns in the guide.
