Explain the code at $ARGUMENTS in clear, accessible language.

Guidelines

1. Start with the big picture

   • What is the overall purpose of this code?
   • Where does it fit in the larger system?

2. Break down the logic

   • Walk through the code step by step
   • Explain non-obvious algorithms or patterns
   • Note any clever tricks or idioms

3. Highlight key concepts

   • Design patterns used
   • Important data structures
   • External dependencies and their roles

4. Call out gotchas

   • Edge cases handled (or not)
   • Assumptions made
   • Potential pitfalls
