Project overview
ai-security-guard combines zero-dependency TypeScript runtime guards with a Claude skill for prompt injection, replayed-history attacks, privilege escalation, forged action markers, cross-tenant PII leaks, media abuse, and unsafe rendering. It can log blocked attacks and propose new patterns, but each candidate must pass a regression check before a human promotes it, so nothing becomes live automatically. The reference code uses Express-style functions that can be ported to other stacks.
