Score: 6.5/10 (Innovation: 6, Technical: 6, Documentation: 7, Utility: 7)

HookGuard scans AI agent configuration files (like CLAUDE.md and Cursor rules) for security threats such as RCE hooks, invisible Unicode, credential exfiltration, and prompt injection. It addresses a novel and practical gap in supply-chain security for AI-assisted development, with clear output and CI integration.

Target audience: security engineers, developers using AI coding agents, devops
