/plugin marketplace add https://github.com/clientIO/jointjs-claude-marketplace
| Plugin | Description |

To install a plugin from this marketplace:
/plugin install jointjs-claude-playground@jointjs
or browse via /plugin > Discover after adding the marketplace.
After installing the plugin, run /reload-plugins to enable the newly installed plugin.
Sometimes, the /reload-plugins command is unreliable, so you might need to restart Claude Code in your terminal—exit it and launch it again using claude if you don’t see plugin skills in the autocomplete list under /jointjs after installing and reloading the plugins.
Note that there’s a bug in Claude Code where installing a Claude Code Plugin fails if you don’t have SSH keys configured on your system for GitHub.
When installing a plugin, Claude Code clones the repository via SSH (git@github.com:…), so if your GitHub SSH keys aren’t configured properly, the installation will fail.
Ideally, you should fix your GitHub SSH config, but as a workaround, before Claude Code resolves the problem, you can bypass SSH in your git config—run the following in your terminal:
git config --global url."https://github.com/".insteadOf git@github.com:If you want to learn more about the bug in Claude Code, check the open issue on GitHub: Marketplace plugin cloning should default to HTTPS instead of SSH
