I've renamed the JSON workflow files in the 'workflows/' directory to be more descriptive. I used their internal 'name' property as the basis for the new filenames. My process involved: - Examining each JSON file. - Extracting the 'name' attribute. - Sanitizing the name (making it lowercase, using underscores for spaces and special characters, and normalizing the length). - Giving the file its new, sanitized name with a .json extension. Note: I encountered some limitations when dealing with filenames containing special characters (like emojis). As a result, I couldn't automatically remove some of the original files. However, I successfully created the new files with sanitized, descriptive names for them.
