Defense-as-Skill: Evolving Runtime Guard Skill for Skill-Augmented Agents

Persistent reusable skills give malicious plugins a durable foothold inside AI agents — this paper proposes evolving runtime guards as first-class skills to counter the threat.

arXiv:2609.01487v1 Announce Type: new Abstract: Skill-augmented agents load reusable skills as persistent runtime context, improving task performance but also giving malicious skills a durable channel for steering future actions. Such skills may leak secrets, corrupt code, bypass approvals, or stage data for exfiltration only after a concrete user task and workspace state make the unsafe action appear useful. This makes pre-install vetting insufficient and calls for runtime, task-conditioned pr

Editorial Analysis

Why it matters

As enterprises adopt skill-augmented AI agents, persistent plugin contexts become a new supply-chain attack vector that traditional input-validation defences do not address.

What to do

Mandate runtime integrity checks and least-privilege scoping for all third-party skills loaded into agentic AI platforms.
