Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install apple-app-performance-diagnosis

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 works through the performance references: memory leaks and retain cycles, Instruments profiling, hangs, app launch, energy, timers and Swift performance, plus MetricKit and console capture. You get a diagnosis and the fixes to apply.
