What problem does it solve?

This Skill helps developers avoid common mistakes when translating formally-verified code from Dafny, Verus, or Coq into Lean 4, ensuring more robust and error-free code.

Core Features & Use Cases

• Avoid Noncomputable Errors: Identifies and resolves issues with noncomputable functions.
• Standard Library Mappings: Offers guidance on Lean's standard library equivalents.
• Prop vs Bool Clarification: Differentiates between logical propositions and computational booleans.
• Natural Number Subtraction and Division: Handles specific Lean behaviors like truncating subtraction and division by zero.
• Import Order and autoImplicit Rules: Ensures correct file structure and variable declaration.
• deriving Clause Limitations: Provides guidance on using Lean's type class derivation features.
• Mutual Recursion and Universe Polymorphism: Offers solutions for complex Lean features.
• Use Case: For a developer translating a Coq module into Lean 4, this Skill can help avoid common pitfalls and ensure the translated code is both correct and efficient.
