🧠 Claude OS

The complete operating layer for Claude.

Commands · MCP Servers · Plugins · Tools · Workflows · Agent Frameworks

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.

📦 What's Inside

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

/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

{
  "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

/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)

🔢 Numbers That Matter

🧭 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.

🗓️ 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.
