Show HN: DRYwall – Claude Code plugin to to deduplicate code with jscpd (github.com)

A new plugin for Claude Code, dubbed DRYwall, has been introduced to tackle the issue of code duplication in software development. Utilizing the powerful jscpd tool, DRYwall automatically detects and eliminates redundant code, promoting the "Don't Repeat Yourself" (DRY) principle. This is especially significant as coding agents like Claude Code often generate new code instead of reusing or refactoring existing code, leading to bloated AI-native codebases. By integrating this functionality directly into Claude Code, developers can streamline the deduplication process, making it more efficient and cost-effective compared to manual prompts. Technically, DRYwall requires Node.js for installation and operates through commands within Claude Code. Users can configure settings in a .drywallrc.json file to tailor the plugin's behavior, including options that respect .gitignore files and set limits on the maximum number of duplicates reported. The plugin supports both manual and autonomous deduplication, allowing developers to supervise refactoring or delegating large-scale tasks to an autonomous agent. This innovation not only enhances code quality but also improves productivity for developers using AI tools in their coding practices.
