Tessary

Tessary provides an open-source platform for ensuring the reliability of production agents. It offers comprehensive monitoring, detection, and root cause analysis capabilities: • Monitors every production trace without sampling • Detects failures and behavioral shifts that sampled evaluations miss • Investigates root causes by analyzing agent codebase • Groups recurring issues into actionable findings • Provides evidence and actionable insights for fixes This platform continuously observes all agent traces as they occur, employing cost-effective, narrow classifiers to identify anomalies. When a consistent issue or change in behavior is identified, Tessary consolidates the affected traces into a single finding. It then validates the problem and performs a deep investigation into its origins, ensuring that in-depth analysis is reserved for verified issues that truly warrant it, thereby keeping monitoring efficient and targeted. Designed specifically for engineering teams and developers deploying and managing agents in production environments. Tessary helps maintain agent performance, quickly diagnose problems, and reduce downtime by providing clear, immediate insights into what broke and why, directly correlating issues with code changes. It's ideal for those seeking robust operational stability and rapid issue resolution for complex agent systems.
