Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install performance-investigation-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 defines the target, reproduces the problem, then profiles the right dimension before any change. You get a localized cause, a single fix and a new measurement that confirms it.
