Can I see what will be deleted before it happens?

Yes, the skill generates a detailed report in '.reports/dead-code-analysis.md' that categorizes findings by severity so you can review the proposed changes.

How does the skill prevent breaking my application?

The skill enforces a strict verification policy: it runs your full test suite before a deletion, applies the change, and re-runs the tests. If any tests fail, the change is immediately rolled back.

What happens if I don't have a test suite?

The skill relies heavily on test verification to ensure safety. It is highly recommended to have a functional test suite configured before running this skill to avoid unintended side effects.

Which tools does it use for code analysis?

It utilizes a combination of knip for unused exports, depcheck for orphaned dependencies, and ts-prune for TypeScript-specific unused exports.

Security & Testing

Safely removes unused code, exports, and dependencies through automated analysis and rigorous test-driven verification.

The Dead Code Refactor skill automates the cleanup of technical debt by identifying unused files, exports, and project dependencies using specialized tools like knip, depcheck, and ts-prune. To ensure project stability, it categorizes every finding by risk level and employs a strict 'test-before-and-after' workflow, automatically rolling back any changes that cause test failures. This skill is ideal for developers looking to reduce bundle sizes, shorten build times, and maintain a lean, manageable codebase without the risk of accidental regressions.
