What

A marketplace is a catalog Claude Code installs plugins from. The marketplace manager in the /plugin menu has these changes:

A built-in marketplace entry is listed. It shows as on, off, or blocked by your organization.
"Turn on" and "Turn off" actions for that entry. Turning it off leaves plugins you installed from it installed.
A note when auto-update is set to off for a marketplace in extraKnownMarketplaces.
The Discover tab shows a message when your organization's policy hides every plugin it would list. Before, it showed nothing.
The plugin details view has a "Switch to" action for moving to another copy of the same plugin.

Claude Code checks whether the built-in marketplace is available before it shows the entry, and can hide it.

Why

These are new options in the plugin menu. You can now control the built-in marketplace from there, and you get an explanation where you used to see an empty screen.

Anthropic's note

Upstream's own release notes for v2.1.287 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.

Added You should know, a built-in mod where a side agent watches your back and flags things you or Claude might miss. Turn it on with /plugin enable cc-plugin-you-should-know@builtin (for first-party sessions with telemetry on)
