What
When the artifact tool lists all artifacts of a named type, it now checks permission rules (your settings for what Claude may do without asking) set for that type:
A deny rule blocks the listing, with the error list_type_rule_denied.
An ask rule not exactly matched by the request's type makes the tool tell Claude to retry with the exact name (list_type_rule_ask_retry).
Why
A rule that blocks or requires approval for a type now also covers listing it. The retry makes sure an ask rule actually shows you a prompt rather than being slipped past with a slightly different name.
