Ask HN: Do LLM agents need a separate safety layer?

[amabito]

LLM agents are good at deciding. They are bad at knowing when to stop.

VERONICA is a failsafe state machine that sits between strategy engines and external systems. It provides: - Per-entity circuit breakers (task A failure doesn't block task B) - SAFE_MODE manual halt that persists across crashes - Atomic state persistence (survives SIGKILL) - Signal-aware graceful shutdown (SIGINT/SIGTERM) - Zero dependencies (pure Python stdlib)

Strategy engines can be replaced. Safety layers cannot.

30-day deployment (0 downtime). 12 crash-recovery events handled (100% state recovery). Avg load: 1.003 ops/sec. Validation: 2,600-second high-load test at 1000 ops/sec sustained (2.6M operations).
