Desktop Plugins panel cannot browse git marketplaces (regression)

Version: Claude Code 2.1.79 · Claude desktop app, Code tab · Windows 11

Summary

The desktop Plugins panel has no way to browse or install plugins from a git-based
marketplace. Discover → Filter → Source offers only All sources, Anthropic,
and Your organization — a configured git marketplace is not a selectable source, and
its uninstalled plugins never appear anywhere in the panel.

The panel's Add ⌄ menu does offer Add marketplace, so a git marketplace can be
registered through the UI but not browsed through it. That combination is the core
of the bug: the UI invites you to add a source it can't then read.

This previously worked — available plugins from a git marketplace were visible in the UI.

Repro

1. Configure a git marketplace (~/.claude/settings.json → extraKnownMarketplaces,

or the panel's Add ⌄ → Add marketplace):

``json
"prolink": {
"source": { "source": "git", "url": "https://github.com/ORG/REPO.git" }
}
``

1. Ensure the marketplace catalog contains at least one plugin that is not installed.
2. Open Settings → Plugins → Discover.
3. Try Filter → Source. Only All sources / Anthropic / Your organization exist.
4. The uninstalled git-marketplace plugin appears under neither Discover nor

Your plugins, and the search box does not find it.

Expected

Git marketplaces should be a selectable Source, and their uninstalled plugins should be
browsable and installable from Discover — matching what the CLI already returns.

Actual

Git-marketplace plugins are invisible in the panel until installed by CLI. After a CLI
install they show up under Your plugins, so the panel can render them; it just won't
offer them.

The CLI has the data

claude plugin list --available --json

...correctly returns the uninstalled plugin in its available array with the right
marketplaceName. So this is a UI gap, not a catalog or config problem.

Workaround

claude plugin marketplace update <marketplace-name>
claude plugin install <plugin-name>@<marketplace-name>

Note that claude plugin install <plugin>@<marketplace> fails with
Plugin "<plugin>" not found in marketplace "<marketplace>" if the marketplace clone is
stale — the documented pre-install refresh did not happen here, so
marketplace update was required first. That may be a second, separate bug.
