AI is becoming increasingly interactive with web platforms, yet few are designed to effectively support this interaction. Agent Experience (AX) aims to optimize the experience of AI agents using digital services, ensuring they can autonomously navigate and complete tasks within modern web ecosystems. The open source contributors have created Principles of AX that provide a framework for applying these practices, focusing on human centricity, agent accessibility, and contextual alignment. For developers, this means rethinking how to build applications that incorporate AI agents as central participants. Businesses that design platforms with agents in mind will enable better automation, improve efficiency, and enhance customer experiences, while those who don't risk falling behind in an AI-driven world. AX will define how businesses adapt to the evolving generation of consumption and interaction, making it essential for developers and businesses to review the Principles of AX and assess their current agent experience.
