Anyone from Anthropic here?

The bottom of the article mentions:

"To see plugins in action, try this multi-agent workflow we use to develop Claude Code

`/plugin marketplace add anthropics/claude-code`"

So I tried it out and got myself into:

"Failed to clone marketplace repository: SSH authentication failed. Please ensure your SSH keys are configured for GitHub, or use an HTTPS URL instead.

Original error: Cloning into '/Users/brutalcoding/.claude/plugins/marketplaces/anthropics-claude-code'...

fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists."

Fixed it by running this instead: "/plugin marketplace add https://github.com/anthropics/claude-code".

It makes sense to me, but I just wanted to point it out :-)

Huh, interesting. Must be an issue on my side then. I'll figure it out, thanks for letting me know

Distribution is going to be key here... plugin maintainers do not want to have to build a marketplace as well as a plugin.

Luckily, I just vibe coded https://claudecodemarketplace.com

Got a plugin? Raise a PR.
