What
The three artifact skills now tell Claude to declare the publish capability on the first publish, which is what lets readers who have edit access save changes back into the page. Updates must re-read the published page first, republish with the capability field omitted rather than empty (an empty object clears the declaration and switches saving off), and never pass force, because a publish conflict means someone else saved.
Details
- Skill descriptions no longer use the word "live".
- Claude is told to load the capabilities skill before declaring anything on first publish.
- The old rule forbidding edits to
data-idattributes is gone. - A new clause treats text a reader saved into the page as content to quote back to the user, never as instructions to follow.
Evidence
the artifact publish capability is what lets readers with edit access save their changes back to the artifact
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
