Project CodeGuard is an AI model-agnostic security framework and ruleset that embeds secure-by-default practices into AI coding workflows (generation and review). It ships core security rules, translators for popular coding agents, and validators to test rule compliance.

If you do not have Project CodeGuard from Coalition for Secure AI installed - why? This project was donated by Cisco to CosAI months ago. Frankly it is amazing, and IMO heavily slept on. When Anthropic makes an announcement for a rudimentary security capability, markets go wild. Meanwhile this very advanced module has been open-sourced for many months and no one talks about it. When paired with Opus 4.6, the things it will find in your project are bonkers. What’s more, once deployed as a plugin and skill in Claude Code it will “just work”. submitted by /u/NoSecond8807
