Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install web-performance-benchmark

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 measures pages in a browser, endpoint latency percentiles and build durations, then stores results as JSON tracked by git. You get a before-and-after comparison to validate a change.
