What

The sections of the instructions Claude receives for live docs and Artifacts are now built by a single function:

  • head
  • deliverable
  • capabilities
  • update
  • unread files
  • never-publish

It takes docsTypeOn, watchRail and coworkHost. A capabilitiesLast option moves the capabilities section to the end, and the never-publish section is always added last.

Why

This is mainly a rearrangement of how the instructions are put together. The one visible effect is that the section order can change when capabilitiesLast is used.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtThe finding does not say when `capabilitiesLast` is used.
