Installation
pip install strands-harnessnpm install @strands-agents/harnessIf you don't write code
I want to start and test the AI agent loop by installing the strands-harness package in my Python or TypeScript environment. Could you write the code that will allow me to create a simple agent and give it a sample task after installing the required library?
Repository: https://github.com/strands-agents/harness-sdk. Follow the official instructions in the README of this repository for setup and execution.
Before starting, check which OS we are on and if the necessary tools (e.g., Python, Node.js, Git, Docker) are installed. Install any missing ones step-by-step according to this system.
Create a new, empty folder to work in. Do not touch any files outside this folder and do not delete anything. Tell me what you are going to do in one sentence before running each command.
Tell me what I should see on the screen at the end of each step. If an error occurs, I will paste the error message to you exactly as it is, and we will fix it together.
