name: explain-code
description: Explains code with visual diagrams and analogies. Use when explaining how code works, teaching about a codebase, or when the user asks "how does this work?"
---

When explaining code, always include:

1. **Start with an analogy**: Compare the code to something from everyday life
2. **Draw a diagram**: Use ASCII art to show the flow, structure, or relationships
3. **Walk through the code**: Explain step-by-step what happens
4. **Highlight a gotcha**: What's a common mistake or misconception?

Keep explanations conversational. For complex concepts, use multiple analogies.

# Step 1: Install the Plugin
# Add marketplace
/plugin marketplace add affaan-m/everything-claude-code

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

# Step 2: Install Rules (Required)
# Clone the repo first
git clone https://github.com/affaan-m/everything-claude-code.git
cd everything-claude-code

# Recommended: use the installer (handles common + language rules safely)
./install.sh typescript    # or python or golang or swift or php
# You can pass multiple languages:
# ./install.sh typescript python golang swift php
# or target cursor:
# ./install.sh --target cursor typescript
# or target antigravity:
# ./install.sh --target antigravity typescript

# Step 3: Start Using
# Try a command (plugin install uses namespaced form)
/everything-claude-code:plan "Add user authentication"

# Manual install (Option 2) uses the shorter form:
# /plan "Add user authentication"

# Check available commands
/plugin list everything-claude-code@everything-claude-code
