The performance-tool.py script is designed to analyze and improve the performance of custom themes in web projects. It performs various checks to identify potential issues in theme files, such as missing attributes, non-optimized images, and inline styles/scripts.

The tool performs the following checks:

1. Libraries.yml (Async/Defer): Ensures JavaScript files in libraries.yml have async or defer attributes.
2. Non-Optimized Images (CSS & Twig): Detects non-WebP image formats in CSS and Twig files.
3. Inline CSS/JS in Twig: Flags excessive inline <style> and <script> tags in Twig templates.
4. Missing Alt Attributes: Identifies <img> tags in Twig files that are missing alt attributes for accessibility.
5. Large Images in CSS/Twig: Checks for images larger than 500 KB in CSS and Twig files.
6. Missing Async/Defer in <script>: Ensures inline <script> tags in Twig files have async or defer attributes.

This repository includes GitHub workflows to automate testing and validation:

• Test Performance Tool Action: This workflow, defined in .github/workflows/test.yml, allows you to manually trigger a test of the performance tool using the workflow_dispatch event. It runs the tool against the specified theme directory (./themes/custom/custom-theme by default) to ensure it functions as expected.

1. Clone the repository:

   git clone https://github.com/rahulsavaria/Performance-tool.git
