TL;DR

AWS introduces ToolSimulator, an LLM-powered testing framework within Strands Evals SDK that safely validates AI agents using external tools without risking live API calls or PII exposure. The tool simulates tool behavior to catch integration bugs, test edge cases, and enable multi-turn workflow validation at scale.

• •LLM-powered simulation replaces risky live API calls and brittle static mocks
• •Catches integration bugs early and validates edge cases comprehensively
• •Available now as part of Strands Evals SDK for production-ready agent deployment
