| """The developer-assistant tools. Master prompt 6: a capability inside BOTH modes. | |
| "The tone follows the mode; the substance is identical." So each tool runs a specialist, | |
| mode-free sub-call that returns JSON, and Prova's own turn presents that result in whichever | |
| voice the mode calls for. Nothing here knows or cares which mode it is in. | |
| Each result is also returned as an *artifact* — the web app renders a review as a diff view and | |
| an API design as a table (master prompt 6's UI list), rather than as prose. | |
