When users ask "how do I do X" or "is there a skill for that," this routes them to the open skills ecosystem instead of you fumbling through a generic answer. It wraps the Skills CLI (npx skills find) and helps match their need to an installable skill, then handles the install-skill.sh flow. The smart bit is the trigger detection: it activates on capability questions, not just explicit "find me a skill" requests. Honestly most useful in the early days of building with skills, when users don't yet know what exists. Once you've got your core skills installed, you'll rarely need this, but it beats manually searching skills.sh when someone asks if there's something for PR reviews or React performance.
