What building-multiagent-systems does

building-multiagent-systems covers architecture patterns for multi-agent systems in Claude Code. It focuses on the relationship between an orchestrator, sub-agents, and the tools they use while a task is being carried out.

Use it when you need to shape a system with several cooperating agents rather than treat each agent as an isolated worker. The plugin’s subject is architecture: assigning roles, arranging agent handoffs, and coordinating tool use. That makes it a focused choice for multi-agent design work.

Install it from the claude-community marketplace. The plugin targets Claude Code.

What it helps with

split work between an orchestrator and sub-agents
design cooperation between several agents
coordinate tool calls across agents
choose a pattern for a multi-agent architecture

Example prompts for the agent

Design a multi-agent system with an orchestrator and several sub-agents.
Show how the agents should divide responsibilities and coordinate tool calls.
Suggest an architecture pattern for coordinating multiple agents.

# 2389 Research Claude Code Plugin Marketplace

28 plugins and MCP servers for Claude Code — parallel exploration, iterative refinement, binary reverse engineering, structured decision-making, and more.

Built by the team at [2389](https://2389.ai). These are the tools we use every day.

**Browse the marketplace:** https://skills.2389.ai

## Quick Start

Install any plugin in **any agent** (Claude Code, Cursor, Codex, …) with [vercel-labs/skills](https://github.com/vercel-labs/skills):

```bash
npx skills add 2389-research/simmer
```

Or natively in Claude Code:

```bash
# Add the marketplace, then install any plugin
/plugin marketplace add 2389-research/claude-plugins
/plugin install simmer@2389-research
```

> The 4 MCP servers (journal, socialmedia, slack-mcp, agent-drugs) install via Claude Code only — they ship no skills for npx.
