Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install swiftui-performance-analysis

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 identifies scrolling contexts, view body complexity and update triggers, then looks for anti-patterns: file I/O in body, formatters created on each render, image processing in body and containers without lazy loading. You get a report ranked by severity.
