Quick Start: Master Everything Claude Code in 5 Minutes

What You'll Learn

Everything Claude Code is a Claude Code plugin that provides professional agents, commands, rules, and hooks to help you improve code quality and development efficiency. This tutorial helps you:

✅ Complete Everything Claude Code installation in 5 minutes
✅ Use the /plan command to create implementation plans
✅ Use the /tdd command for test-driven development
✅ Use /code-review for code reviews
✅ Understand the plugin's core components

Your Current Challenges

You want Claude Code to be more powerful, but:

❌ You repeatedly explain coding standards and best practices
❌ Low test coverage and frequent bugs
❌ Code reviews always miss security issues
❌ You want TDD but don't know where to start
❌ You want professional sub-agents to handle specific tasks

Everything Claude Code solves these problems:

9 specialized agents (planner, tdd-guide, code-reviewer, security-reviewer, etc.)
14 slash commands (/plan, /tdd, /code-review, etc.)
8 enforced rules (security, coding-style, testing, etc.)
15+ automated hooks
11 workflow skills

Core Concepts

Everything Claude Code is a Claude Code plugin that provides:

Agents: Specialized sub-agents that handle domain-specific tasks (like TDD, code review, security auditing)
Commands: Slash commands that quickly launch workflows (like /plan, /tdd)
Rules: Enforced rules that ensure code quality and security (like 80%+ coverage, no console.log)
Skills: Workflow definitions that reuse best practices
Hooks: Automated hooks that trigger on specific events (like session persistence, console.log warnings)

What is a Claude Code Plugin?

Claude Code plugins extend Claude Code's capabilities, just like VS Code plugins extend editor functionality. Once installed, you can use all agents, commands, skills, and hooks provided by the plugin.

🎒 Prerequisites

You need:

Claude Code installed
Basic understanding of terminal commands
A project directory (for testing)

You don't need:

No special programming language knowledge required
No pre-configuration needed

Follow Along: 5-Minute Installation

Step 1: Open Claude Code

Launch Claude Code and open a project directory.

You should see: Claude Code's command-line interface ready.

Step 2: Add Marketplace

In Claude Code, run the following command to add the marketplace:

bash

/plugin marketplace add affaan-m/everything-claude-code

Why Add Everything Claude Code as a Claude Code plugin source so you can install plugins from it.

You should see:

✓ Successfully added marketplace: everything-claude-code

Step 3: Install Plugin

Run the following command to install the plugin:

bash

/plugin install everything-claude-code@everything-claude-code

Why Install the Everything Claude Code plugin so you can use all the features it provides.

You should see:

✓ Successfully installed plugin: everything-claude-code@everything-claude-code

Step 4: Verify Installation

Run the following command to view installed plugins:

bash

/plugin list

You should see:

Installed Plugins:
  everything-claude-code@everything-claude-code

✅ Installation successful!

Step 5: Use /plan to Create an Implementation Plan

Suppose you want to add user authentication, run:

bash

/plan I need to add user authentication with email and password

Why Use the planner agent to create a detailed implementation plan and avoid missing key steps.

You should see:

# Implementation Plan: User Authentication with Email and Password

## Requirements Restatement
- User registration with email and password
- User login with email and password
- Password hashing with bcrypt
- JWT token generation
- Session management

## Implementation Phases
[Detailed implementation steps...]

## Risks
- HIGH: Password security (use bcrypt, salt rounds)
- MEDIUM: JWT token expiration
- LOW: Email uniqueness validation

## Estimated Complexity: MEDIUM
**WAITING FOR CONFIRMATION**: Proceed with this plan? (yes/no/modify)

Enter yes to confirm the plan, and the planner will start implementation.

Step 6: Use /tdd for Test-Driven Development

When implementing features, run:

bash

/tdd I need to implement a function to validate email format

Why Use the tdd-guide agent to enforce the TDD workflow, ensuring tests are written first before code implementation, achieving 80%+ coverage.

You should see:

# TDD Session: Email Format Validator

## Step 1: Define Interface (SCAFFOLD)
```typescript
// lib/email-validator.ts
export interface ValidationResult {
  isValid: boolean
  error?: string
}

export function validateEmail(email: string): ValidationResult {
  // TODO: Implementation
  throw new Error('Not implemented')
}

Step 2: Write Failing Test (RED)

[Test code...]

Step 3: Run Tests - Verify FAIL

[Test failure...]

✅ Tests fail as expected. Ready to implement.

Step 4: Implement Minimal Code (GREEN)

[Implementation code...]

Step 5: Run Tests - Verify PASS

[Test pass...]

Step 6: Refactor (IMPROVE)

[Refactored code...]

Step 7: Verify Tests Still Pass

[Tests still pass...]

Step 8: Check Coverage

Coverage: 100% ✅ (Target: 80%)

✅ TDD session complete!

### Step 7: Use /code-review to Review Code

Before committing code, run:

```bash
/code-review

Why Use the code-reviewer agent to check code quality, security, and best practices.

You should see:

# Code Review Report

## Overview
- Files reviewed: 3
- Total lines: 150
- Issues found: 2

## Issues Found

### 1. [CRITICAL] Hardcoded JWT Secret
**Location**: `lib/auth.ts:15`
**Issue**: JWT secret is hardcoded in source code
**Fix**: Move to environment variable
**Impact**: Security vulnerability - secret exposed in code

### 2. [MEDIUM] Missing Error Handling
**Location**: `lib/email-validator.ts:23`
**Issue**: No error handling for null/undefined input
**Fix**: Add null check at function start
**Impact**: Potential runtime errors

## Recommendations
✓ Tests are well written
✓ Code is readable
✓ Follows TypeScript best practices

**Action Required**: Fix CRITICAL issues before commit.

After fixing issues, run /code-review again to confirm all issues are resolved.

Checklist ✅

Confirm you have successfully completed the following steps:

[ ] Successfully added marketplace
[ ] Successfully installed everything-claude-code plugin
[ ] Used /plan to create an implementation plan
[ ] Used /tdd for TDD development
[ ] Used /code-review for code review

If you encounter issues, check Troubleshooting Hooks or MCP Connection Failures.

Common Pitfalls

Installation Failure

If /plugin marketplace add fails, ensure:

You're using the latest version of Claude Code
Network connection is normal
GitHub access is working (may need proxy)

Commands Not Available

If /plan or /tdd commands are not available:

Run /plugin list to confirm the plugin is installed
Check if plugin status is enabled
Restart Claude Code

Windows Users

Everything Claude Code fully supports Windows. All hooks and scripts are rewritten using Node.js to ensure cross-platform compatibility.

Summary

✅ You have:

Successfully installed the Everything Claude Code plugin
Understood core concepts: agents, commands, rules, skills, hooks
Experienced three core commands: /plan, /tdd, /code-review
Mastered the basic TDD development workflow

Remember:

Agents are specialized sub-agents that handle specific tasks
Commands are quick entry points to launch workflows
Rules are enforced rules ensuring code quality and security
Start with features that resonate, then expand gradually
Don't enable all MCPs, keep fewer than 10
