A few weeks ago, I deleted 93 skills in a single pull request. If you haven&rsquo;t worked with them, a skill is a small bundle of instructions you hand to the model, a workflow you&rsquo;ve written down once so it runs the same way every time, the kind of thing you&rsquo;d reach for when you&rsquo;re chasing down a flaky test, or pulling together the context for an incident at 2 am.
