Design by Contract FAQs

Question 1

How does this skill improve the development workflow?

Accepted Answer

It introduces a structured PLAN-CREATE-VERIFY-REMEDIATE workflow. Claude helps you identify contract gaps, generate the necessary annotations, run validation suites, and provides targeted strategies to fix contract violations when they occur.

Question 2

What is the Design by Contract Claude Code Skill?

Accepted Answer

It is a specialized capability for Claude Code that automates the lifecycle of formal software contracts. It helps developers plan, implement, and verify preconditions, postconditions, and invariants across multiple programming languages to ensure runtime correctness and robustness.

Question 3

When should I use Design by Contract in my project?

Accepted Answer

It is ideal for defining public API boundaries, ensuring the correctness of critical business logic, maintaining object consistency in state management, and formally documenting expected behavior for team collaboration.

Question 4

What is the 'Verification Hierarchy' feature?

Accepted Answer

This feature prioritizes static assertions and compile-time checks over runtime contracts. It ensures that your code is optimized by only using runtime overhead for properties that cannot be verified by the type system or compiler.

Question 5

Which programming languages are supported?

Accepted Answer

The skill supports over 8 major languages, including Rust (using the contracts crate), TypeScript (using Zod), and Python (using icontract), as well as Java, Kotlin, and C++ through language-specific contract patterns.
