Skills not in their notes

The whiteboard skill gained opening sketches, named boards and clearer send-permission errors, but stays switched off.

A substantially reworked whiteboard skill and page ship, but its enable check calls a helper that returns false.

--title
What

The whiteboard skill and its bundled page were substantially reworked, but registration still gates on a helper that returns false, so none of it is reachable.

Details
  • Claude is instructed to draw an opening sketch of its read of the design before anything else.
  • The page is built through merge-state.mjs, which gains a --title flag naming the board "Whiteboard — <topic>" and refuses to silently rename a board that was already sent.
  • Republishing with capabilities re-declared happens only when the user says Send to Claude is unavailable.
  • The bundled page restyles onto inlined Claude Design System tokens.
  • The Send button is now disabled at load with a specific reason when the permission state is permanently blocked, rather than the block being discovered on first click; permanent and transient permission codes are handled separately.
  • Toasts gain a configurable duration.
  • Gate: isEnabled returns PQi() && j2e(), and PQi() returns !1.

whiteboard send blocked

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
