Part of the document and spreadsheet skills, which are hard-disabled in this build.
What
When one of the new document or spreadsheet skills runs, its instruction file is assembled at invocation rather than sent whole, so Claude is only told to do things the artifact actually supports.
Details
- A marked block instructing Claude to act on reader comments (make the edit, reply, resolve) is kept only when the artifact has a thread id, and deleted otherwise.
- A trailing note is appended only when the artifact reports capabilities.
- Front matter is stripped, and anything the user typed after the command is appended under a
## User Requestheading. - Unreachable in this build, since both skills are registered as disabled.
Evidence

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