We can easily mark a form field as *required*. But what if we could also mark it as “fillable by AI” or “copyable”?
An AI-fillable field needs a prompt and a button that generates its value. A copyable field needs a button that places its current value on the clipboard. These are two different capabilities, but they pose the same architectural question: how can we make each capability reusable while configuring it naturally for individual fields?
In this live-coding session, I’ll show you how to do it using one of the least talked-about features of Signal Forms: *custom metadata*. We’ll create our own reusable *schema* functions such as fillWithAI(...) and copyable(...), then build a reusable field wrapper that discovers these capabilities and automatically renders the appropriate UI.
The result is a clean, extensible pattern for giving form fields new *superpowers* - directly from the schema.
