VERONICA: A Safety Layer for LLM Agents

This article discusses the need for a separate safety layer for LLM agents, highlighting their potential for uncontrolled behavior. VERONICA is presented as a solution, acting as a failsafe state machine between strategy engines and external systems. It offers per-entity circuit breakers, preventing task A failure from blocking task B. A SAFE_MODE manual halt persists across crashes, ensuring controlled shutdown. Atomic state persistence guarantees survival after SIGKILL signals. Signal-aware graceful shutdown handles SIGINT/SIGTERM signals. VERONICA has zero dependencies, relying solely on pure Python stdlib.

The system has demonstrated reliability with 30-day deployment and 12 crash-recovery events with 100% state recovery. It sustained 2.6 million operations in a high-load test. Installation is straightforward via pip using the provided GitHub repository. The article emphasizes that strategy engines can be replaced, but safety layers are critical and cannot.

VERONICA's design prioritizes stability and recovery, making it a valuable component for deploying reliable LLM agents. Its lightweight nature and lack of external dependencies make it easily adaptable to various applications.
