Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install trading-card-price-lookup

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 finds the card in the Midpoint database, then gives its dollar value from real sales, its price history and the gap between PSA 9 and PSA 10. Each result shows its capture date and links to the source card page.
