After saving a custom skill (like a financial statement review skill) to Claude, how do I actually use it for a new client?

Once you've saved the skill file to your Claude library (using 'add to library' or 'update and replace'), you can invoke it in two ways: type a slash ('/') in the chat to bring up a menu of your saved skills and select it, or simply reference it directly in your prompt, e.g. 'Hey, use the financial statement review skill and do this.' This lets you reuse the same skill for each new client without recreating it.
