Whiteboard prompt distinguishes viewer saves from sends and pushes answers onto the board; skill is off.

What

The skill instructions teach Claude to distinguish a viewer save from a send and to put answers on the board rather than in prose. Off in this build.

Details
  • a viewer Submit republishes without flagging Claude, so ping.n decides: a value higher than the one already handled is a send to answer on the board, an unchanged one is a save to absorb without drawing back
  • board text is capped to short labels and one-line questions
  • ids must be cl_ prefixed and at most 40 characters
  • arrows may not bind to another arrow, line or freehand stroke
  • a line or two of reasoning in chat is now allowed
  • gate: whiteboard skill isEnabled g5v = Wms() && Ige(), and Wms returns !1
Evidence

An answer is drawn, not written

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