Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install apple-app-performance-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 picks the right method for the problem (hangs, memory, launch, energy, thermal), applies a targeted fix and checks the result with real measurements. It can also add os_signpost measurement points and MetricKit tracking.
