Claude Plugins Now Installable in Two Commands via GitHub Mirror

Anthropic is the company behind Claude. The newly surfaced repository collects community plugins that work across both Claude Cowork, its conversational collaboration product, and Claude Code, its coding agent. Back on August 17, Claude Code gained a /design skill in research preview that could sketch out UI drafts. This marketplace is a different kind of move, though — instead of Anthropic building those extensions itself, it opens a channel for outside developers to build and distribute them.

What's in the Repository

Looking at the repository's file list, alongside the configuration folders .claude-plugin and .github, there are four plugin folders: eli5, quickdesign, testdino, and tres-finance-plugin. Judging by the names alone, tres-finance-plugin looks like it's built for finance work, while quickdesign appears to help with design-related tasks. In the repository description, Anthropic states that every plugin on this list has been "submitted via claude.ai, passed automated security scanning" (GitHub repository README).

How to Try It

Where to Start

Claude Cowork users install plugins from the claude.com/plugins page, while Claude Code users type commands directly into the terminal.

Step-by-Step

1. Type claude plugin marketplace add anthropics/claude-plugins-community into the terminal. This command registers the community marketplace repository with Claude Code.
2. Check the name of the plugin you want, then type claude plugin install <plugin-name>@claude-community. For example, to use the quickdesign plugin, you'd type claude plugin install quickdesign@claude-community.
3. In Claude Cowork, just click the plugin you want from the claude.com/plugins list to install it — that's it.

Who Can Use It

This is available to users of both Claude Cowork and Claude Code. The repository documentation doesn't specify country availability or pricing-tier conditions.

What You Can Do With It

If your company has its own financial reporting templates, for instance, a job-specific plugin like tres-finance-plugin could be installed team-wide to cut down on repetitive work. A tool like quickdesign, meanwhile, can be used to quickly rough out screen drafts in the middle of a coding session.

How Approval Works

Submitting a pull request directly to this repository gets it automatically closed. To distribute a plugin, developers instead have to submit it through clau.de/plugin-directory-submission. Once submitted, a plugin only gets approved and reflected in the repository — on the nightly sync — after passing an automated security scan inside Anthropic's internal review pipeline. In other words, developers aren't pushing code straight into the repo; what's public is only what Anthropic has already filtered through.

The Claude Plugin Ecosystem Keeps Growing

Under the same account, there are two more repositories with a different character.

Repository	Managed By	Details
claude-plugins-community	Community submissions + Anthropic review	Read-only mirror, synced nightly
claude-plugins-official	Managed directly by Anthropic	Plugins built in-house by Anthropic
knowledge-work-plugins	Managed directly by Anthropic	Job-specific plugins (accounting, legal, etc.)

According to Korean media reports, Anthropic called Korea its "fastest-growing market" when it opened a Seoul office this past June, and other overseas AI companies such as OpenAI and Mistral AI set up a presence in Korea around the same time. That naturally creates an incentive for Korean companies to publish their own internal-use plugins on this marketplace.

Editor's Take

This repository's appearance is one piece of Anthropic's larger push to turn Claude from a single product into an extensible platform. If MCP was the wiring standard that plugged Claude into outside tools and data, this marketplace is the consumer-facing outlet that lets you plug into that wiring with two commands, without writing any of it yourself. Previously, adding a new capability to Claude Code meant writing an MCP server config file by hand. Now the bar has dropped to just knowing the marketplace-registration and install commands.

From a practical standpoint, this resembles the extension ecosystems around GitHub Copilot or the VS Code Marketplace. There's one difference worth flagging, though: review runs entirely inside Anthropic's internal pipeline, and there's no external way to check the review criteria. If a Korean team is planning to build an internal-only plugin, it would save time to ask Anthropic directly what the automated security scan actually checks for before public distribution.

In the coming weeks, expect more industry-specific plugins to show up alongside general-purpose ones like eli5 and quickdesign. If plugins named directly after job functions — in the style of tres-finance-plugin — keep multiplying, Claude Cowork and Claude Code will start splitting away from being general-purpose assistants and toward becoming industry-specific toolkits.
