Gemini powered Site Kit Assistant.

[benbowler]

Summary

A WIP branch to develop a Site Kit Assistant.

Relevant technical choices

In the first PoC I used the javascript SDK, before switching to the PHP SDK, August 2024. I also updated the assistant to have a number of supported areas of knowledge and use a multiple request approach where Gemini first classifies the question type before another request is made with specific context in order to answer that question.

In this second version I use the Key Metrics widget API and Gemini selects the best widget to show which is a great way to allow the assistant to surface data from across the plugin without having to load this data into it's own context.

In a future update I will import the Site Kit documentation to allow users to ask questions of this.
