Which versions of TypeScript does this skill cover?

The skill focuses on modern TypeScript features from versions 5.5 through 5.8, including preparation for the architectural changes coming in TypeScript 7.

Does this skill support plain JavaScript projects?

No, this skill is specifically optimized for .ts and .tsx files. For projects using plain JavaScript with JSDoc annotations, the standard JavaScript skill is recommended.

Does it help with ESM migration?

Yes, it enforces modern ESM conventions, including proper package.json exports, named export preferences, and avoiding problematic barrel files.

How does this skill improve error handling?

It promotes the use of the Result pattern for expected failures over thrown exceptions and utilizes error cause chains to maintain debugging context across asynchronous boundaries.

What is the benefit of the 'satisfies' operator mentioned in the skill?

The 'satisfies' operator allows you to validate that an object matches a specific type while retaining the most specific inferred type for its properties, which is superior to standard type casting.
