Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install swiftui-performance-audit-profiling

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 starts with a code review of the view, then guides measurement in Instruments if the review is inconclusive. It identifies causes such as expensive formatters in body, heavy computed properties or filtering inside ForEach, and proposes fixes.
