Note

Low Risk
Low risk: adds a new read-only CLI command and extends marketplace parsing with an optional description field, without changing install/update behavior.

Overview
Adds a new hf skills list (alias ls) command that fetches marketplace skills and prints a table including name/description plus whether each skill is installed in the four supported locations (project/global and Claude project/global).

Extends marketplace parsing by adding an optional description field to MarketplaceSkill, and updates the generated CLI reference docs to include the new command.

I see that both are possible, but I would just use one in the docs.

Nice! I was just looking for this and couldn't find it in the latest release.
Also, should we have a hf skills remove ... just to mirror the add?
