exactly what tags are supported by the markup text.
Want to create a system instruction for a JSON schema, that returns a markup formatted response, it would be helpful to know exactly what markup tags are supported for the markup text control.
Documentation does not say
Markup Text
Like a static text string, except it supports simple HTML markup, including clickable links.
Adding Dialog Controls [Directory Opus Manual]
It's generally the same markup used in button labels and evaluator columns.
This thread has the best list of things it can do:
The markup functionality was made mainly for internal use, and we didn't think people would use it much in buttons/columns, but it is turning out to be more useful than we expected, and was requested for use in dialogs as well. It was an "unofficial" feature, but is used enough now that it's a supported thing.
Making some proper docs for it is on our list, although not a top priority right now. The first few posts in the thread above cover most of the details.
Just tell it basic HTML markup. You don't need a JSON schema for that, AFAIK.
