Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install pixel-image-diffing-odiff

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 runs odiff on two PNG, JPEG or WebP images, writes a diff image and reads the exit codes for CI. You get a verdict and an image of the changed pixels.
