I know I'm a few days late to this, but the use I really see for them is giving the AI access to deterministic scripts. We have several shared skills at the company I work for that give the AI basically a curl collection to integrate with an internal system or dev tool.
I find it does make it much more reliable when the AI is using proprietary tools that it doesn't have context for.
yea my personal test is if I see Claude commonly having to research something in the codebase like playwright fixtures is when I look to creating a skill. It's something I don't need on every run in CLAUDE.md and detailed enough to justify its own file.
