Explain code with analogies and diagrams

---

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 code 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.
