What
claude plugin list no longer names the account in its header for plugins synced from claude.ai; it now reads as a plain "Synced from claude.ai", still followed by the warning when sync is off in the current shell.
Evidence

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