How agents misuse their tools — excessive and redundant tool calls, and dangerous unsandboxed access to real-world systems.

2 patterns

Tool Thrashing

🚫

Intermediate

Agent calls tools excessively, redundantly, or incorrectly — searching for the same thing multiple times, calling tools in the wrong order, or making unnecessary API calls.

Unsandboxed Execution

🚫

Advanced

Giving agents direct access to production systems, real databases, or real-world actions without sandboxing, rollback, or approval gates.
