Unclear What user-facing feature or check this capability cache feeds into is not shown by the finding.

What

A new internal function caches an artifact's server-declared capabilities, keyed to the specific tool call that fetched them, and reports whether those capabilities are known to be empty or are still unknown.

Why

This appears to be internal plumbing supporting artifact behavior rather than something a reader interacts with directly; the finding doesn't show what feature it enables.
