# Agents guide — 2389 Research Claude Code Plugin Marketplace

This site is the official catalog of Claude Code plugins and MCP servers from 2389 Research Inc. It is generated from `.claude-plugin/marketplace.json` in [2389-research/claude-plugins](https://github.com/2389-research/claude-plugins).

## What's here

- The homepage at [https://skills.2389.ai/](https://skills.2389.ai/) lists every plugin grouped into Development, Infrastructure, Agent Systems, and Personal & Strategy.

- Each plugin has its own page under `/plugins/{name}/` with the full README, install command, and source link.

- A [glossary](https://skills.2389.ai/glossary/) defines marketplace-specific terms (plugin, skill, MCP server, hook, scorecard).

- Machine-readable index files: [sitemap.xml](https://skills.2389.ai/sitemap.xml), [sitemap.md](https://skills.2389.ai/sitemap.md), [llms.txt](https://skills.2389.ai/llms.txt).

- Every HTML page advertises a markdown mirror via `<link rel="alternate" type="text/markdown" href="…/index.md">`. Fetch the `index.md` URL directly for the markdown copy.

## Install a plugin

Default — any agent (Claude Code, Cursor, Codex, …) via [vercel-labs/skills](https://github.com/vercel-labs/skills):

```

npx skills add 2389-research/<plugin-name>

```

Or natively in Claude Code:

```

/plugin marketplace add 2389-research/claude-plugins

```

(MCP servers — slack-mcp, agent-drugs, socialmedia, journal — install via Claude Code only; they ship no skills for npx.)
