No Rules (baseline) 52.0%
Free OWASP Skill† 64.4%
Free Snippet (ours) 70.0%
Full Skill Pack 92.8%

Everything You Need to Ship (Much) More Secure Code

  • Core security rules (558 lines) covering OWASP Top 10 (2021), OWASP Top 10 for LLM Applications (2025), and OWASP Top 10 for Agentic Applications (2026)
  • 14 framework-specific reference files for React, Next.js, Node.js, Express, Django, Flask, FastAPI, Rails, Laravel, Spring Boot, Go, Rust, ASP.NET, and more
  • Pre-built platform files for Claude Code (.skill), Cursor (.cursorrules), GitHub Copilot (.github/copilot-instructions.md), Windsurf (.windsurfrules), and OpenAI (system-prompt.md)
  • Self-check mechanism that forces the AI to verify its output against security rules before responding
  • Free updates as new frameworks, platforms, and OWASP standards are added

Why the Full Skill Pack?

We benchmark every release across 20 real-world coding prompts and 250 security assertions. Here's how everything stacks up.

No Rules (baseline) 52.0% (130/250)
Free OWASP Skill† 64.4% (161/250)
Free Snippet (ours) 70.0% (175/250)
Full Skill Pack 92.8% (232/250)

agamm/claude-code-owasp — all conditions tested on the same 250 assertions

The free snippet covers all 17 security domains in compact form. The full pack adds 14 framework-specific reference files, detailed implementation patterns, and a 12-point self-check mechanism that forces the AI to verify its output before responding.
The 23-point gap between snippet and full pack is where the hard stuff lives: framework-specific traps (Flask autoescape is OFF by default), agent memory security, multi-agent trust boundaries, LLM output hardening (URL validation, PII scanning, schema-validated structured output), and denial-of-wallet defenses.
Even our free snippet (70.0%) outperforms the most popular free OWASP skill on GitHub (64.4%) — on the same 250 assertions. The full pack scores 28 points higher.
