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.
|
|
Shorthand Guide
Setup, foundations, philosophy. Read this first. |
Longform Guide
Token optimization, memory persistence, evals, parallelization. |
| 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 |
This plugin now fully supports Windows, macOS, and Linux. All hooks and scripts have been rewritten in Node.js for maximum compatibility.
Package Manager Detection
The plugin automatically detects your preferred package manager (npm, pnpm, yarn, or bun) with the following priority:
- Environment variable:
CLAUDE_PACKAGE_MANAGER
- Project config:
.claude/package-manager.json
- package.json:
packageManager field
- Lock file: Detection from package-lock.json, yarn.lock, pnpm-lock.yaml, or bun.lockb
- Global config:
~/.claude/package-manager.json
- Fallback: First available package manager
To set your preferred package manager:
# Via environment variable
export CLAUDE_PACKAGE_MANAGER=pnpm
# Via global config
node scripts/setup-package-manager.js --global pnpm
# Via project config
node scripts/setup-package-manager.js --project bun
# Detect current setting
node scripts/setup-package-manager.js --detect
Or use the /setup-pm command in Claude Code.

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.
Copy desired MCP servers from mcp-configs/mcp-servers.json to your ~/.claude.json.
Important: Replace YOUR_*_HERE placeholders with your actual API keys.
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
Running Tests
The plugin includes a comprehensive test suite:
# Run all tests
node tests/run-all.js
# Run individual test files
node tests/lib/utils.test.js
node tests/lib/package-manager.test.js
node tests/hooks/hooks.test.js
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:
- Start with what resonates
- Modify for your stack
- Remove what you don’t use
- Add your own patterns
