What
When Claude Code needs to extract a skill's type definitions because its authoring guidance isn't otherwise available, the message it shows now distinguishes between skills: for core, built-in skills it says "calling this capability," while for other, declared skills it keeps saying "declaring this capability."
Why
This makes the guidance more accurate, since core skills are invoked directly ("called") while other skills are only declared for use, helping anyone reading the message understand the distinction correctly.
