TrustLog Dynamics: Python Daemon Uses Bond Math to Kill Rogue AI Agents

TrustLog Dynamics is an open-source Python daemon that monitors AI agent API costs in real time and terminates rogue processes using detection methods borrowed from quantitative finance. The tool addresses the problem of AI agents spending money continuously without oversight, drawing inspiration from trading floor circuit breakers.

Detection Methods

The daemon uses two specific detection algorithms:

• Convexity detection (d²C/dt² > 0) — borrowed from fixed-income risk management. When cumulative cost accelerates over time (snowballing), the daemon kills the agent at the inflection point.
• Zero-variance detection (σ² < ε) — borrowed from statistical process control. When rolling cost variance drops to near zero, indicating the agent is stuck in a mechanical loop, the daemon severs the connection.

Testing Results

The developer tested TrustLog Dynamics live against two AI models:

• Claude 4.6 Sonnet (context window explosion) — caught and terminated
• Gemini 3.1 Pro (retry loop) — caught and terminated

Both interceptions were recorded on video: Claude intercept and Gemini intercept.

Installation and Deployment

The tool requires three commands to install and runs as a systemd daemon. It's released under MIT license with source code available at GitHub.

The developer positions this as a financial governance layer for AI agents, inspired by NVIDIA's NemoClaw for network security and Jensen Huang's recent comments about OpenClaw strategies. The approach uses mathematics that has been protecting capital markets for decades.
