Document artifacts no longer claim commenting is available; sheets and slides still do.
What's wrong with this entry?
The doc, sheet and slides artifact skills now each declare whether commenting works, and the note appended to the prompt is built per skill: docs say "editing and persistence are", sheets and slides say "editing, persistence, and commenting are". Previously one fixed sentence always claimed commenting was wired.
- These skills are registered with an availability check that returns false in this build, so they do not appear regardless.
- The note is only appended when the artifact capability information is present.
editing, persistence, and commenting are
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
