Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install frontend-perceived-performance

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 every wait, decides for each mutation between optimistic and pessimistic updates, removes avoidable waits and masks the rest, and fixes LCP, INP and CLS. You get an audit ranked by user impact and the code for the fixes.
