A plugin = an AI employee with skills, commands, and access built in.

What Claude Code plugins are, where to find them, and why you need them. Anthropic's marketplace: marketing, sales, design. Plus how to build your own.

Claude Code plugins

A skill is a single muscle. A plugin is a whole specialist: a marketer, a salesperson, a designer. Anthropic has built its own marketplace, and almost nobody is talking about it yet.


The AI employee store

Finance. Sales. Marketing. One prompt.

Claude Code ships with a built-in plugin store, already stocked with ready-made specialists from Anthropic. A marketer. A salesperson. A designer. No setting things up from scratch: install it, call it, it works.

`` $ claude > /plugin marketplace browse → Opens the list of plugins available in your Claude Code ``


Where to find it

The store is already built into Claude Code.

01 · Open Claude Code

In your terminal, run claude inside your project folder.

02 · Open the marketplace

Run this inside the session:

`` /plugin marketplace browse ``

You'll see the list of available marketplaces. Anthropic's is connected by default.

03 · Install the plugin you need

For example, Anthropic's marketing plugin:

`` /plugin install marketing ``

Done. All of the plugin's commands, /marketing:campaign-plan, /marketing:performance-report, and so on, are available right away.

Don't have Claude Code?

Start with installing Claude Code in 5 minutes. Plugins only work there: the browser version of Claude doesn't have this feature yet.


What it is

Not a single file. An entire department behind one button.

A plugin is a set of related tools built around a specific role. Inside Anthropic's marketing plugin you'll find skills for every job a marketer does: campaign planning, metrics reporting, competitive analysis, email campaigns, SEO audits. All under one brand, all working together.

Every plugin can bundle skills, slash commands, subagents, MCP servers, and hooks. It's not a single .md file but a whole folder with a configured workflow. Install it once and your project gains a new role.

Why you need them

So you don't have to hire a team.

01 · Speed: no writing prompts from scratch

Every plugin is a set of templates from domain experts, packaged into commands. No need to remember how a marketer plans a campaign: type /marketing:campaign-plan and you get a ready-made brief with metrics.

02 · Cohesion: one department, one context

Commands inside a plugin are aware of each other. A report from /marketing:performance-report can go straight into /marketing:campaign-plan with no data lost along the way.

03 · Standards: Anthropic-grade quality

Plugins in the official marketplace are built by the people who made the model itself. This isn't some random YouTube guide; it's production-grade prompting for Claude 4.7.

04 · Extensibility: you can build your own

If the marketplace doesn't have what you need, build your own plugin, drop it into a GitHub repo with a plugin.json, and any Claude Code can install it. That's how we build plugins for the Russian market.

How to build your own plugin

A GitHub repo + a manifest. That's it.

01 · Create a GitHub repo

Any name, public or private (if it's private, users will need a token).

02 · Add the plugin structure

The skills/, commands/, and agents/ folders, plus a plugin.json file describing the plugin.

03 · Add the repo as a marketplace

In Claude Code: /plugin marketplace add github.com/your/repo. From there it's a normal install via /plugin install.


Frequently asked

How is a plugin different from a skill or MCP?

TypeDescription
SkillA single .md file with instructions for one task. For example, /smm.
MCP serverA connection to an external service (GitHub, Notion, Postgres). Gives Claude access to data. What MCP is.
SubagentA parallel helper with a narrow role. Launched from a skill or another agent. Multi-agent systems.
PluginA bundle of all of the above. One plugin = multiple skills + commands + subagents + optionally MCP + hooks. An entire role in a single install.
