Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install target-size-distance

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 checks the size and position of clickable targets using Fitts's Law. You get recommendations on target size and placement, especially for touchscreens.
