Agent-watchdog

Agent Watchdog provides essential runtime protection for multi-agent systems, preventing indefinite loops and token waste. Key features include: • Real-time loop detection • Message similarity analysis • Tool-call pattern monitoring • Intervention and recovery capabilities This tool acts like a circuit breaker for agent graphs, identifying when agents begin rephrasing the same arguments or enter silent deadlocks. By watching message similarity and tool-call patterns, Agent Watchdog halts stuck processes before they consume excessive resources. This proactive intervention distinguishes it from retrospective analysis tools, ensuring immediate action. The system offers a default similarity threshold and minimal detection overhead, ensuring that your agent graphs run efficiently without unnecessary resource expenditure. When a loop is detected, it provides an intervention report, detailing the trigger, iterations, and similarity percentage at the point of intervention, preventing further token burn. Agent Watchdog is ideal for developers and teams building sophisticated agent-based applications, particularly those using frameworks like LangGraph, who need to ensure the reliability and cost-effectiveness of their systems. It helps ship robust processes that do not unexpectedly deplete budgets due to runaway operations.
