What languages and package managers are supported?

The auditor supports Node.js (npm), Python (pip), and Rust (cargo) for package version and outdated dependency checks.

Does this skill automatically update my code?

No, it is a specialized auditor that identifies issues and provides recommendations. It returns findings in a JSON format that can be used by developers or other automated tools to perform updates.

How does it detect 'reinvented wheels'?

The skill uses specialized patterns to search for custom implementations of common tasks that could be handled by the native standard library or well-tested packages like Lodash or Date-fns.

How is the compliance score determined?

The skill uses a penalty-based algorithm where High, Medium, and Low severity issues subtract from a perfect score of 10, providing a quick benchmark of project health.

Security & Testing

Audits project dependencies and code reuse to identify outdated packages, unused libraries, and custom implementations of standard features.

The Dependencies & Reuse Auditor (L3) is a specialized worker designed to streamline software supply chain management and maintain code quality within the Claude Code ecosystem. It systematically analyzes package manifests and source code to detect outdated dependencies, identify unused production or development libraries, and flag 'reinvented wheels' where custom code replicates features already available in the standard library or installed packages. By providing a quantified compliance score and actionable remediation steps, it helps developers reduce bundle sizes, mitigate security risks, and improve overall maintainability during the delivery workflow.

Key Features
