The Artifact listing tool now accepts a scope parameter with three values: mine (the default, unchanged), shared (artifacts that other people shared with you), or all (both together).
Details
scope only applies to the list action; publishing ignores it.
Listing shared artifacts requires one-time consent per session — the first call that touches the shared scope shows a confirmation prompt because it reads titles and links from other users' sessions.
A fresh consent prompt is shown only on the first shared or all listing per session; subsequent calls within the same session are silently permitted.
Evidence
New Pje scope resolver (search for "scope: shared —") and new consent flow (search for "First shared-scope artifact listing this session requires confirmation")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
