What it does when it runs

When the user wants to increase deal sizes, upsell existing opportunities, or expand accounts during the sales process. Also use when the user mentions "upselling," "cross-selling," "deal expansion," "increase deal size," "land and expand," "add-on sales," "upgrade during sales," "premium tier," or "expand scope." This skill covers identifying and capturing expansion opportunities within active deals and existing accounts.

Or take the whole library

This repo ships a .claude-plugin manifest, so Claude Code can install all 122 skills at once. Plugin skills are invoked as /<plugin>:<skill>, so they never collide with your own.

/plugin marketplace add louisblythe/Sales-Skills

The folder is the same in every client that implements the format — 46 of them — so if yours is not above, only the destination changes.

The skill

Source on GitHub ↗

The source carries no licence at all, so no permission to redistribute it exists. Everything else on this page is our own reading of the file and is published here; the text of the skill is not, and stays where its author put it.
