Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install retail-price-comparison

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent compares one product, identified by its UPC code, across more than 70 retailers, and spots price drops and large discounts. It can also estimate whether a product is profitable to resell on Amazon.
