Ask HN: What software needs to be tailored to AI agents?

I recently came across a winning project from TreeHacks (Stanford) that was basically an AI-native website. The dev made an HOC that could be wrapped around UI components (somewhat like ARIA labels) and communicated their purpose, appearance, and location to the agent.

He paired it with a GSM that synchronized user-agent interactions in real time allowing one to actually interact with a website through natural language.

This got me thinking, what type of software actually needs integrations like this? Do we need forms that agents can fill? APIs that agents can access? Payment gateways for agents?
