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:
/plugin marketplace add 2389-research/claude-plugins
Or cherry-pick individual plugins:
/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 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. Fork it, modify it, ship your own.
