Can I target specific directories with this skill?

Yes, you can provide a specific library path as an argument (e.g., libs/my-feature) to limit the scan to a particular part of your codebase.

What is considered a redundant barrel file?

A barrel file (index.ts) is considered redundant if it contains only one export statement and serves as an intermediate layer that could be bypassed by exporting directly from the parent file.

Does this skill support automatic refactoring?

Yes, after providing a report, the skill offers an auto-fix option that updates the parent directory's exports and deletes the redundant file for you.

How does removing barrel files benefit my project?

It reduces the complexity of the import graph, makes navigation easier in IDEs, and can slightly improve TypeScript compilation times by reducing the total number of files to process.

Developer Tools

Identifies and removes redundant TypeScript barrel files to simplify module architecture and improve codebase maintainability.

The Check Barrel Files skill automates the detection of unnecessary index.ts files that serve as single-item re-exporters. It scans your specified directory to find intermediate barrel files that add no structural value, providing a detailed markdown report of the findings. Beyond just reporting, it offers an intelligent auto-fix capability that updates parent export paths to point directly to the source file and safely deletes the redundant index files, streamlining your project's import graph and reducing boilerplate.
