Everything Claude Code

The complete collection of Claude Code configs from an Anthropic hackathon winner.

Production-ready agents, skills, hooks, commands, rules, and MCP configurations evolved over 10+ months of intensive daily use building real products.

The Guides

This repo is the raw code only. The guides explain everything.

Start Here: The Shorthand Guide

The Shorthand Guide to Everything Claude Code

The foundation - what each config type does, how to structure your setup, context window management, and the philosophy behind these configs. Read this first.

---

Then: The Longform Guide

The Longform Guide to Everything Claude Code

The advanced techniques - token optimization, memory persistence across sessions, verification loops & evals, parallelization strategies, subagent orchestration, and continuous learning. Everything in this guide has working code in this repo.

Topic	What You'll Learn
Token Optimization	Model selection, system prompt slimming, background processes
Memory Persistence	Hooks that save/load context across sessions automatically
Continuous Learning	Auto-extract patterns from sessions into reusable skills
Verification Loops	Checkpoint vs continuous evals, grader types, pass@k metrics
Parallelization	Git worktrees, cascade method, when to scale instances
Subagent Orchestration	The context problem, iterative retrieval pattern

Installation

Option 1: Install as Plugin (Recommended)

The easiest way to use this repo - install as a Claude Code plugin:

# Add this repo as a marketplace
/plugin marketplace add affaan-m/everything-claude-code

# Install the plugin
/plugin install everything-claude-code@everything-claude-code

Or add directly to your ~/.claude/settings.json:

{
  "extraKnownMarketplaces": {
    "everything-claude-code": {
      "source": {
        "source": "github",
        "repo": "affaan-m/everything-claude-code"
      }
    }
  },
  "enabledPlugins": {
    "everything-claude-code@everything-claude-code": true
  }
}

This gives you instant access to all commands, agents, skills, and hooks.

---

Option 2: Manual Installation

If you prefer manual control over what's installed:

# Clone the repo
git clone https://github.com/affaan-m/everything-claude-code.git

# Copy agents to your Claude config
cp everything-claude-code/agents/*.md ~/.claude/agents/

# Copy rules
cp everything-claude-code/rules/*.md ~/.claude/rules/

# Copy commands
cp everything-claude-code/commands/*.md ~/.claude/commands/

# Copy skills
cp -r everything-claude-code/skills/* ~/.claude/skills/

Add hooks to settings.json

Copy the hooks from hooks/hooks.json to your ~/.claude/settings.json.

Configure MCPs

Copy desired MCP servers from mcp-configs/mcp-servers.json to your ~/.claude.json.

Important: Replace YOUR_*_HERE placeholders with your actual API keys.

Read the Guides

Seriously, read the guides. These configs make 10x more sense with context.

1. Shorthand Guide - Setup and foundations
2. Longform Guide - Advanced techniques (token optimization, memory persistence, evals, parallelization)

---

Key Concepts

Agents

Subagents handle delegated tasks with limited scope. Example:

---
name: code-reviewer
description: Reviews code for quality, security, and maintainability
tools: Read, Grep, Glob, Bash
model: opus
---

You are a senior code reviewer...

Skills

Skills are workflow definitions invoked by commands or agents:

# TDD Workflow

1. Define interfaces first
2. Write failing tests (RED)
3. Implement minimal code (GREEN)
4. Refactor (IMPROVE)
5. Verify 80%+ coverage

Hooks

Hooks fire on tool events. Example - warn about console.log:

{
  "matcher": "tool == \"Edit\" && tool_input.file_path matches \"\\\\.(ts|tsx|js|jsx)$\"",
  "hooks": [{
    "type": "command",
    "command": "#!/bin/bash\ngrep -n 'console\\.log' \"$file_path\" && echo '[Hook] Remove console.log' >&2"
  }]
}

Rules

Rules are always-follow guidelines. Keep them modular:

~/.claude/rules/
  security.md      # No hardcoded secrets
  coding-style.md  # Immutability, file limits
  testing.md       # TDD, coverage requirements

---

Contributing

Contributions are welcome and encouraged.

This repo is meant to be a community resource. If you have:

• Useful agents or skills
• Clever hooks
• Better MCP configurations
• Improved rules

Please contribute! See CONTRIBUTING.md for guidelines.

Ideas for Contributions

• Language-specific skills (Python, Go, Rust patterns)
• Framework-specific configs (Django, Rails, Laravel)
• DevOps agents (Kubernetes, Terraform, AWS)
• Testing strategies (different frameworks)
• Domain-specific knowledge (ML, data engineering, mobile)

---

Background

I've been using Claude Code since the experimental rollout. Won the Anthropic x Forum Ventures hackathon in Sep 2025 building zenith.chat with @DRodriguezFX - entirely using Claude Code.

These configs are battle-tested across multiple production applications.

---

Important Notes

Context Window Management

Critical: Don't enable all MCPs at once. Your 200k context window can shrink to 70k with too many tools enabled.

Rule of thumb:

• Have 20-30 MCPs configured
• Keep under 10 enabled per project
• Under 80 tools active

Use disabledMcpServers in project config to disable unused ones.

Customization

These configs work for my workflow. You should:

1. Start with what resonates
2. Modify for your stack
3. Remove what you don't use
4. Add your own patterns
