The README opens with

A Pi extension that keeps the Agent Skills catalog out of model requests and replaces it with one ranking tool backed by TypeSafe's Jev System One model.

Skills stay loaded, so /skill:name keeps working. Before each agent turn the extension removes Pi's generated catalog from the effective system prompt and gives the model two tools to pull skills in on demand.

skillsearch takes a plain-language description of the task, rates every enabled skill against it, and returns the complete SKILL.md instructions of the skills that apply.
