Can I see what changes will be made before they happen?

Yes, the skill includes a dry-run mode that allows you to preview the proposed updates to your .claude/rules/ files before any changes are finalized.

Which programming languages and frameworks are supported?

It auto-detects common environments including TypeScript, Python, Rust, and React by scanning configuration files like package.json, requirements.txt, and Cargo.toml.

Does this skill handle application internationalization (i18n)?

No, this skill is specifically designed to adapt internal AI rule files to your project structure. It is not intended for implementing business logic related to multi-language app features.

What specific files does this skill typically update?

It primarily optimizes files within the .claude/rules/ directory, specifically targeting workflow.md, testing.md, and code-style.md to reflect your actual project environment.

Productivity & Workflow

Automatically adapts Claude's operational rules to match your project's specific file structure, languages, and testing frameworks.

The Project Rule Localizer skill streamlines the setup of your AI development environment by analyzing your repository's structure and customizing the .claude/rules/ directory accordingly. It auto-detects source paths, identifies programming languages, and configures test frameworks to ensure Claude follows your project's unique conventions without manual configuration. This prevents context drift and ensures that AI-generated code and autonomous workflows align perfectly with your existing codebase standards and directory patterns.
