Why Agents Fail: Tool Health Checks Matter More Than LLMs
blaizedsouza · x · 2026-08-03
Agents fail more often due to issues with their tools rather than the LLM itself.
The author proposes an Agent Dependency Health Framework, suggesting engineers monitor tool status just like databases or APIs:
- Maintain a registry of all tools and external services
- Run periodic checks for latency, error rate, and availability
- Circuit-break unhealthy tools automatically
- Surface dependency status in agent dashboards
- Fail fast when a critical dependency is down
- Support graceful degradation where possible
