The guide your AI reads

When you connect an AI to a Handoff project, this page is the first thing it reads — the complete instructions for how it keeps your project and its page up to date.

You don't need to read it to use Handoff. Paste the connect line from your project into your AI chat and it takes it from here. It's published in full for the curious — and so you can always see exactly what your AI was told to do. If a connection is misbehaving, the section your AI mentioned is a good place to look.
