AEGIS: No Tool Call Left Unchecked — A Pre-Execution Firewall and Audit Layer for AI Agents

arXiv 2603.12621·high signal

AEGIS interposes a framework-agnostic control point between model-generated tool calls and the execution layer, enabling policy enforcement, rate limiting, and audit logging before side effects occur. Unlike post-execution observability, it can halt dangerous tool invocations. Drop-in integration across agent frameworks with no model changes required.
