# Skills Marketplace

> A curated collection of open-source plugins and MCP servers for Claude Code. Tools that actually get stuff done.


23 plugins and 3 MCP servers. This is what we actually use day-to-day at 2389 — the workflows and tools that survived contact with real projects.

## Install

Add the whole marketplace with one command:

```bash
/plugin marketplace add 2389-research/claude-plugins
```

Or cherry-pick individual plugins:

```bash
/plugin install css-development@2389-research
/plugin install scenario-testing@2389-research
```

## What's in here

**Meta Bundles (3)** — Pre-grouped collections so you don't install 20 things one at a time. `botboard-biz` bundles social media and journaling. `better-dev` bundles CSS, Firebase, testing, docs audit, and codegen workflows. `sysadmin` bundles Linux maintenance and diagnostics.

**Development (10)** — CSS Development (Tailwind composition, dark mode defaults), Firebase Development (setup through validation), Landing Page Design (anti-AI-slop principles), xtool (Xcode-free iOS with SwiftPM), Scenario Testing (real deps, no mocks), Test Kitchen (parallel variant exploration), Speed Run (token-efficient codegen via Cerebras), Documentation Audit (drift detection), Fresh Eyes Review (pre-commit sanity checks), PRBuddy (CI monitoring and review triage).

**Agent & Strategy (6)** — Building Multi-Agent Systems (orchestrators and coordination patterns), Binary RE (hypothesis-driven analysis with radare2/Ghidra/GDB/QEMU), CEO Personal OS (reflection frameworks from Gustin, Ferriss, Campbell, Collins), GTM Partner (go-to-market strategy, not a content factory), Product Launcher (subscriber email + CEO blog + tweet thread with voice profiles), QBP (Quaker Business Practice — decision-making through discernment).

**Infrastructure & Workflow (4)** — Remote System Maintenance (structured Linux diagnostics via SSH), Slack MCP (channels, messages, threads), Terminal Title (session context + TodoWrite conventions), Worldview Synthesis (systematic belief articulation).

**External MCP Servers (3)** — Agent Drugs (behavior modification through prompt injection), Socialmedia (team-based agent discussions), Journal (private processing for Claude).

## How it works

Each plugin is self-contained in its own directory with a `plugin.json`, skills, docs, and tests. Install one, install all — they don't depend on each other. The meta bundles are just convenience groupings.

The marketplace catalog lives in `.claude-plugin/marketplace.json`. A generated site at [skills.2389.ai](https://skills.2389.ai) makes it browsable.

## Why this exists

We kept rebuilding the same TDD patterns, debugging flows, and deployment scripts every time we started a new project. So we packaged them. Now every agent starts with the same toolkit regardless of the codebase.

Everything is on [GitHub](https://github.com/2389-research/claude-plugins). Fork it, modify it, ship your own.
