Unclear It is unclear whether there is an api-version skill you can actually use.

What

Claude Code keeps a list of names for built-in skills and commands, with entries such as cost-optimize, migrate and upgrade. A skill is a packaged set of instructions Claude can use for a task. An empty slot in that list now holds the name api-version.

Why

This may mean a new built-in skill, or only that a name slot was filled in.
