What
A skill is a packaged set of instructions Claude can use for a particular task. The skill for running tests now has the short description "Run tests on this machine (local)". The longer text that used to be its description now sits in the part that says when to use the skill.
Why
This changes how the skill appears wherever skills are listed.
