Cowork worker prompt can now tell workers to check for existing 'Cowork types' before authoring plain HTML
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.
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.
Whether this guidance is switched on could not be traced; the condition controlling it is not resolved by the evidence.
