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.

#1. 计划模式 进行探索：Claude 阅读文件并回答问题，无需更改文件。
#2.  Create a plan. 按 Ctrl+G 在文本编辑器中打开计划，直接编辑，然后 Claude 继续。
I want to add xxxx. What files need to change? What's the session flow? Create a plan.
#3. 切回普通模式，让claude 编码，并对照计划进行验证。
implement the xxxx from your plan. write tests for the callback handler, run the test suite and fix any failures.
#4. commit提交 
commit with a descriptive message and open a PR
