 ## What is Project CodeGuard?
-[Project CodeGuard](https://project-codeguard.org/) is an AI model-agnostic security framework and ruleset (internally nicknamed "Project CodeGuard" when developed at Cisco) 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.

 Project CodeGuard is designed to integrate seamlessly across the entire AI coding lifecycle. 
-- **Before code generation**, skills and rules can be used for the design of a product and for spec-driven development. You can use the rules in the “planning phase” of an AI coding agent to steer models toward secure patterns from the start.

 - **During code generation**, skills and rules can help AI agents to prevent security issues as code is being written.
 - **After code generation**, AI agents like Cursor, GitHub Copilot, Codex, Windsurf, and Claude Code can use the rules for code review.
