Unclear Whether this guidance is switched on could not be traced; the condition controlling it is not resolved by the evidence.

What

When a session includes the Cowork publish tool, the prompt given to a delegated worker can now include extra guidance that things like slide decks, presentations, or visual designs are not just plain .html pages. In that case, the worker is instructed to first list the published Cowork types available and start from a matching type before falling back to authoring plain HTML.

Why

This steers delegated workers toward using purpose-built Cowork formats for things like presentations, instead of defaulting to generic HTML, when that guidance is in effect.
