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.

Artifact prompt text loses its commenting variant

You'll notice
Useful1 Signal2
Artifacts

Artifact instructions no longer mention commenting, because the skills that used that wording are gone.

What

The prompt appended to the built-in document artifact skill used to switch between saying "editing, saving, and commenting are" and "editing and saving are" depending on the skill. The two skills that used the commenting wording are gone, so the sentence is now fixed at the non-commenting form, and a clause about a document edited in place is stripped from the shared template text.

Details
  • The per-skill commenting flag is gone from the skill descriptions and the helper no longer takes an argument.
  • Only reachable if the artifact skills are ever switched on; in this build they are not.
Evidence

"This template publishes an editor whose editing and saving are already wired. If the user wants behavior beyond that \u2014 the page reading"

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