Defense-in-Depth Validation FAQs

Question 1

What is the Defense-in-Depth Claude Code skill?

Accepted Answer

It is a specialized capability that teaches Claude to implement four layers of validation—Entry, Business, Environment, and Debug—to ensure data integrity throughout a system.

Question 2

Is this skill only for TypeScript developers?

Accepted Answer

While the provided patterns use TypeScript examples, the defense-in-depth principles are language-agnostic and can be applied to any backend or frontend development stack.

Question 3

How does multi-layer validation prevent bugs?

Accepted Answer

By validating data at every checkpoint it passes through, the system ensures that even if one validation point is bypassed by a mock or a new code path, subsequent layers will catch the error.

Question 4

What are 'Environment Guards' in this context?

Accepted Answer

Environment Guards are checks that prevent dangerous operations, such as file deletions or API calls, from running in unintended contexts like automated test environments.

Question 5

When should I apply the Defense-in-Depth pattern?

Accepted Answer

Apply this pattern when fixing bugs caused by invalid data, handling critical user input, or when performing operations that could have high-impact side effects if data is malformed.
