Amazon researchers release Simple Strands Agent for better agent performance

Amazon scientists launched a new open-source harness to fix the gap between what AI models intend and what tools actually do. The system improves reliability across multiple benchmarks without needing specific tuning for each model.

Key points

Simple Strands Agent (SSA) is an open-sourced single-agent harness designed to minimize intent-execution gaps.
The research was published on arXiv under the title Dissecting model behavior through agent trajectories.
SSA achieves state-of-the-art performance on SWE-Pro, SWE-Verified, and Terminal-Bench2 benchmarks.
Model families differ in tool use preferences, making model-harness codesign critical for optimal results.

Why it matters: Better harnesses reduce the cost of fixing errors and improve safety by preventing accidental code corruption during agent execution.

The harnesses that mediate between models and tools in agentic systems are becoming their own performance bottleneck, but a few simple design principles can fix what ails them.
