## The Problem
You can spend 40 hours searching GitHub, Reddit, Medium, and Anthropic's docs —
and still not have a complete picture of what Claude can actually do.
The ecosystem exploded in 2025–2026.
- **14,600+** repositories indexed
- **1,200+** MCP servers available
- **400+** plugins and skills
- **25+** agent frameworks
- **100+** commands and prompt codes
Nobody documented all of it in one place.
> “This isn’t a resource. It’s a complete operating layer for Claude.”
**Until now.**

## Claude OS — Layer Model
This is a framework, not just a collection.
1. **Commands** — Interaction
2. **MCP** — Execution
3. **Plugins** — Capabilities
4. **Tools** — Infrastructure
5. **Workflows** — Automation
6. **Agents** — Intelligence scaling
## Start Here If You Have 10 Minutes
- Install 3 plugins
- Add Memory MCP
- Try Builder–Validator
---
## ⚡ Quick Wins — 5 Things to Do Right Now
### 1. Install the 3 plugins that matter most
```bash
/plugin marketplace add obra/superpowers-marketplace
/plugin install superpowers@superpowers-marketplace # Plans before it builds
/plugin install context7@claude-plugins-official # Live docs, no hallucinated APIs
claude skills add juliusbrussee/caveman # 65-75% fewer output tokens
```
### 2. Set up your core MCP servers
```json
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/projects"]
},
"github": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-github"],
"env": { "GITHUB_PERSONAL_ACCESS_TOKEN": "your_token" }
},
"memory": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-memory"]
}
}
}
```
### 3. Initialize project memory
```bash
/init # Creates CLAUDE.md — Claude reads this every session
/memory # Edit it with your stack, conventions, and rules
```
### 4. Learn the 5 keyboard shortcuts that save the most time
```
Shift+Tab → Cycle modes: Normal → Auto-Accept → Plan Mode
Ctrl+R → Search command history
Esc Esc → Rewind conversation or code
Ctrl+T → Toggle task list
/compact → Compress context when it hits 70%
```
### 5. Use the right thinking mode for the right task
```
L99 → Maximum reasoning depth (architecture decisions)
XRAY → Root cause analysis (debugging)
OODA → Tactical decisions under uncertainty
BEASTMODE → Maximum effort, no shortcuts
/plan → Force planning before execution (production code)
```

## 🧭 The Philosophy Behind This Bundle
Most Claude resources are either:
**Too shallow** — "Here are 10 cool things Claude can do" (no install commands, no real usage)
**Too scattered** — spread across 50 different GitHub repos, Medium articles, and Discord threads
**Too outdated** — written for Claude 2 or early MCP, missing everything from 2025–2026
Claude OS is different. Every entry follows the same structure:
- What it does (one clear sentence)
- Why it matters for Claude specifically
- Working install command or code example
- Honest "best for" and limitations
- Updated to April 2026
**The rule we followed throughout:**
> If you can't explain what a tool does in one sentence and show working code in 10 lines, it doesn't belong here.

## 📈 Verified Production Metrics
Real companies. Real results. What's possible when you use this stack properly.
| Company | Workflow | Result |
|---------|---------|--------|
| **Stripe** | Claude Code across 1,370 engineers | 10k-line migration: 4 days vs 10 engineer-weeks |
| **Ramp** | Incident investigation workflow | 80% reduction in investigation time |
| **Wiz** | Multi-agent code migration | 50k lines Python→Go in ~20hrs (was 2–3 months) |
| **Rakuten** | Feature delivery pipeline | 24 working days → 5 working days |
| **Fountain** | Multi-agent code review | 50% faster delivery |
| **CRED** | Agent teams across dev lifecycle | 2x speed, maintained quality |

## 🗓️ Keeping This Current
Claude Code ships weekly. The ecosystem moves fast.
**How to know if something is outdated:**
- Run `/help` in Claude Code — always shows current command list
- Check `claude --version` before using CLI flags
- MCP server transport syntax changed in 2026 (use `--transport http` for cloud servers)
**Last full audit:** April 28, 2026
**Next planned update:** When Claude Code hits v3.0 or major ecosystem shift

## 🤝 Contributing
Found a command that works but isn't listed?
Know a plugin that deserves Tier 1?
Discovered a workflow pattern that ships faster?
**Open a PR with:**
- Name and one-line description
- Working install command or code example
- "Best for" and honest limitations
- Source (GitHub repo, official docs, your production experience)
We don't accept "it might be useful" entries. Show it working.
