Version 2.0.12:

    • Plugin System Released: Extend Claude Code with custom commands, agents, hooks, and MCP servers from marketplaces
    • `/plugin install`, `/plugin enable/disable`, `/plugin marketplace` commands for plugin management
    • Repository-level plugin configuration via `extraKnownMarketplaces` for team collaboration
    • `/plugin validate` command for validating plugin structure and configuration
    • Plugin announcement blog post at https://www.anthropic.com/news/claude-code-plugins
    • Plugin documentation available at https://docs.claude.com/en/docs/claude-code/plugins
    • Comprehensive error messages and diagnostics via `/doctor` command
    • Avoid flickering in `/model` selector
    • Improvements to `/help`
    • Avoid mentioning hooks in `/resume` summaries
    • Changes to the "verbose" setting in `/config` now persist across sessions

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 :-)

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.

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