From the original repository

Add an Upstream Skill

Use add when you want a workspace entry but do not want to vendor the source.

From the bundled reference library:

npx ai-agent-skills add frontend-design --area frontend --branch Implementation --why "I want this on my shelf."

From a GitHub repo:

npx ai-agent-skills add anthropics/skills --skill ask-questions-if-underspecified --area workflow --branch Planning --why "I use this to tighten vague requests."

add writes to the active workspace only.

It keeps the upstream metadata:

description
source
sourceUrl
installSource
tags
labels
requires

You still choose:

shelf
branch
why it belongs

That keeps the workspace shaped like your own library instead of becoming a blind copy.
