Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install youtube-thumbnail-design-brief

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 designs the concept, text and focal point of the thumbnail, treating it and the title as one unit. It writes the brief for a designer or image tool and plans the A/B test. You get the brief and test plan; the final thumbnail is uploaded natively in YouTube Studio.
