Systematic Type Migration FAQs

Question 1

Why should I keep the old type definition during migration?

Accepted Answer

Keeping both types allows the codebase to remain in a partially migrated but still compilable state. This enables atomic commits per file and prevents the 'Big-Bang' migration errors.

Question 2

Is this migration skill limited to Rust projects?

Accepted Answer

No. While the examples use Rust syntax, the workflow of documenting changes, using parallel types, and performing atomic commits is applicable to any typed language like TypeScript, C++, or Java.

Question 3

What constitutes a good integration test for this workflow?

Accepted Answer

A good integration test exercises the full user flow (e.g., spawn, act, assert result) rather than testing isolated system logic, ensuring all components remain compatible.

Question 4

What is the core principle of the Systematic Type Migration skill?

Accepted Answer

The core principle is an 'Integration test FIRST' approach followed by file-by-file migration, incremental verification, and finally a cleanup phase to ensure system-wide stability.

Question 5

How does this skill prevent integration bugs?

Accepted Answer

It prevents bugs by requiring a full user-flow integration test before migration begins. This ensures that even if individual files compile, the interaction between systems remains intact.
