DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Whiteboard helper script renamed to board.mjs

Skills not in their notes

The whiteboard skill's helper script is now called board.mjs, so older references break.

board.mjs
What

The whiteboard skill's helper, which merges the model's drawing elements into a fetched board and re-emits the page, is now called board.mjs instead of merge-state.mjs. Instructions and notes that reference the old filename will not find it in the skill directory.

Details
  • The skill's file list is now the template plus board.mjs; the script body is an embedded file, so only the name is provably changed.
Evidence

f = { "template.html": a, "board.mjs": s };

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